How to Deploy a Node.js App – From Server Setup to Production

In this tutorial, we are going to learn everything we need to know before deploying a Node app to a production server.

We will start by renting a server on Digital Ocean. Then we'll configure this server, connect to it, install Nginx and configure it, pull or create our Node app, and run it as a process.

As you can see, there is a lot to do and it will be an action-packed tutorial. So let's get started without wasting any time.

You should have some basic knowledge on how the Terminal works and how to work in Vi/Vim before getting started. If you are not familiar with basic commands, I would advise you to read up on them a bit.

I will run the commands in MacOS. If you want to follow this tutorial in Windows, you can use Powershell or some other Unix emulator of your choice.

Although I will use Node.js as the platform of our example application, most of the steps are the same for any web application.

Why Digital Ocean?

I choose Digital Ocean because it is cheap and the interface is really easy to use, compared to the likes of AWS. Also, a $100 credit is included in the GitHub student pack so you do not have to pay anything for a couple of months. It is ideal for deploying a course or hobby project.

It has a concept called Droplets, which is basically your share of a server. You can think of the server as an apartment in which you own or rent a flat.

Droplets work with the help of Virtual Machines which run on the server. So a Droplet is your Virtual Machine on a shared server. Since it is a VM, its CPU and memory share can be easily increased, usually by throwing more money at your provider.

How to Create a Digital Ocean Project

I am assuming that you have already signed up and logged in to Digital Ocean before proceeding. We should first create a project that will contain our droplets. Let's click on the new project button on the left side menu. It will ask you to name your project.

Enter whatever name you want. It will also ask you if you want to move any resources, but for now just click Skip – we will create the droplet later.

How to Create a Droplet on Digital Ocean

Let's create our droplet by clicking the Get Started button.

After clicking the button, it will ask us to choose a VM image.

Choosing an Image

On this page, I will select Ubuntu 20.04 since it is the latest LTS version at the time I am writing this post. LTS means "Long Term Support". It is best to go with the LTS version for actual projects, because the provider guarantees that it will be supported and maintained for a long time. This means you will not have problems in the long run.

I have chosen Ubuntu, and would recommend it to you since it is the most commonly used Linux distribution. This means it's also the easiest to find answers to your future questions.

You can also choose to have a Dedicated CPU if you need it. If you are building your own startup or any business project, I would recommend reading this post which contains detailed instructions about how to pick the right option for you.

I will go with the cheapest option in this case.

Then you will need to select a Datacenter region. You should pick the one that is closest to you to minimize network delay.

Select a Datacenter

Next let's select SSH Keys as the Authentication Method, since it is much more secure than basic password authentication.

Authentication Method

To connect to the server we need to generate a new SSH key on our own device and add it to Digital Ocean.

How to Generate an SSH Key

I will generate the key on my macOS device. If you are using Windows you can refer to this article. Open your terminal and move into the ssh folder:

cd ~/.ssh

Then create your SSH key:

ssh-keygen

If your computer says that it does not know this command, you should install it via brew.

It will ask you to name the file and enter a passphrase. Do not enter a name, just press enter and go with the defaults. You should have these files generated. I have named mine digital-ocean-ssh in this screenshot, so do not get confused by that.

❯ lsid_dsa id_rsa known_hosts

Our public key is the id_dsa and the id_rsa is our private key. If you forget which one is private, you can always print one of them to see.

How to Add Your SSH Key to Digital Ocean

Now we want to copy our public key and upload it to Digital Ocean so they will know which key to use in authentication.

Copy this whole key including the ssh-rsa part.

Click on "New SSH Key":

Paste the key in the textbox that appears after you click the button and you should see your SSH key.

How to Connect to the Server

We will use the terminal to connect to our server with SSH. You can also take a look at Termius for a nice interface if you want.

Run this command in your terminal after replacing the IP_ADDRESS with your server's IP address (you can look it up from Digital Ocean's panel).

ssh root@IP_ADDRESS

If everything goes well, now you should be in the server's terminal. We have successfully connected to server. If there is any error, you can debug it by running the command with the "-v" option or "-vv" for even more verbosity.

How to Set Up the Server

We need to do some initial setup before deploying the Node app to the server.

Update and Upgrade Software

We want to update the server's software to make sure we are using the latest versions.

Many servers are vulnerable to attacks because they are using older versions of software with known vulnerabilities. Attackers can search for the vulnerabilities in those software and try to exploit them in order to gain access to your server.

You can update Ubuntu's software using the "apt update" command.

apt updateHit:1 https://repos.insights.digitalocean.com/apt/do-agent main InReleaseGet:2 http://mirrors.digitalocean.com/ubuntu focal InRelease [265 kB] Hit:3 http://mirrors.digitalocean.com/ubuntu focal-updates InRelease Get:4 http://security.ubuntu.com/ubuntu focal-security InRelease [109 kB]Hit:5 http://mirrors.digitalocean.com/ubuntu focal-backports InReleaseFetched 374 kB in 1s (662 kB/s) Reading package lists... DoneBuilding dependency tree Reading state information... Done96 packages can be upgraded. Run 'apt list --upgradable' to see them.

If you read the message, it says that "96 packages can be upgraded". We have installed the new software packages but we have not upgraded our software to those versions yet.

To do that, let's run another command:

apt upgrade

Type y when it prompts you and it will upgrade the software.

Create a User

We have connected to the server as the root user (the user with the highest privileges). Being the root is dangerous and can open us up to vulnerabilities.

Therefore we should create a new user and not run commands as root. Replace $username with a username of your choice.

whoamiroot

adduser $username

You need to enter a password for the user. After that point, it will ask a bunch of questions, so just input y until the prompting is over.

The new user has been created but we also need to add this new user to the "sudo" group so that we can perform any action we need.

usermod -aG sudo $USERNAME

We add group with the -aG (add group) option, and we add the group name sudo to our username.

We are still root, so let's switch our user to the newly created user, using the su (switch user) command.

su $USERNAME

After this point, if you run whoami command, you should see your username. You can confirm the existence of the sudo group by running this command:

sudo cat /var/log/auth.log

Only superusers can view this file and OS will ask for your user password after you run this command.

Copy the SSH Key

We have successfully created the user but we have not enabled SSH login for this new user yet.

Therefore, we have to copy the public key that we previously created on our local computer and paste it into this user's SSH folder so SSH can know which key should it use to authenticate our new user.

mkdir -p ~/.ssh

The -p argument creates the directory if it does not exist.

vi ~/.ssh/authorized_keys

We will use vi or vim to create a file and call it authorized_keys.

Copy your public key (`id_dsa` file) then press "i" to go into insert mode. Then just paste it into this file with CMD + V.

Press esc to quit insert mode, type :wq to save and quit.

If you have any problems about using Vim-Vi, you can check out one of the many tutorials that explain how to use it.

Connect to Server as New User

Now we should be able to connect to the server without any problems using ssh. You can use this command to connect, just remember to insert your username and IP_ADDRESS.

ssh $USERNAME@IP_ADDRESS

If you are having any problems at this point, you should just delete the droplet and start over. It does not take a lot of time to start over but debugging server problems can be difficult.

How to Disable Root Login

It is a good practice to disable Root login as a security precaution, so let's do that now.

It can be useful to change the file permission just in case so that we won't run into problems regarding permissions in the future.

chmod 644 ~/.ssh/authorized_keys

Let's now open our sshd_config file:

sudo vi /etc/ssh/sshd_config

Find this line and change the yes to no in the same way we did earlier with vi.

PermitRootLogin no

Save and quit vi.

How to Install Node.js and Git

We can now go ahead and install Node.js and Git:

sudo apt install nodejs npm

sudo apt install git

We are now ready to create a Node app and run it. You can either pull your Node project from Github or create a Node app here just to test if it works.

Move to a directory of your choice and create an "app.js" file:

sudo vi app.js

You can paste the following snippet into your app.js file:

const express = require('express');const app = express();const port = 3000;app.get('/', (req, res) => { res.send('Hello World');});app.listen(port, () => console.log(`Example app listening on port ${port}!`));

Now we can run it with the command:

node app.js

You should see "Example app listening on port 3000!" on your terminal.

We can confirm that it is working by sending a request to our server:

GET http://IP_ADDRESS:3000/

Send this request either from an HTTP client like Postman or your browser and you should see the "Hello World" message.

At this point, you should notice that something is wrong: Regular users do not know how to send requests to port 3000.

We should redirect the requests that come to our web server from our IP to port 3000. We can accomplish this with the help of Nginx.

How to Install and Configure Nginx

We will use Nginx as a Reverse Proxy to redirect the requests to our Node app.

Nginx as a Reverse Proxy

Let's install Nginx:

sudo apt install nginx

Start the Nginx service:

sudo service nginx start

We can test to see if it is working by sending a request to our server's IP address from the browser. Type your server's IP address to your browser and you should see this:

It is important to know that Nginx serves from "/var/www/html" by default and you can find this HTML file in that directory as well.

I also advise you to create a folder under "/var/www", call it app, and move your Node app to that folder so it will be easy to find.

How to Configure the Nginx Reverse Proxy

We will edit the Nginx config file to configure a reverse proxy:

sudo vi /etc/nginx/sites-available/default

In this file you need to find the location / block and change it as follows:

location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. proxy_pass http://127.0.0.1:3000/; }

The proxy_pass directive proxies the request to a specified port. We give the port that our Node application is running on.

Let's restart Nginx so the changes can take effect:

sudo service nginx reload

After this step, we should be able to see the message when we send a request to our server. Congratulations, we have completed the minimum number of steps to deploy a Node app!

But I still advise you to complete the following bonus step as well, as I believe it's quite important.

If you can't see the hello world message, you can check if your app and Nginx are running and restart them.

How to Run your App as a Process

We do not want to start our application manually every time something goes wrong and our app crashes. We want it to restart on its own. Also, whenever the server starts, our app should start too.

To make this happen, we can use PM2. Let's install PM2 and configure it.

sudo npm i -g pm2

We are installing pm2 globally by using the "-g" option so that it will be accessible from every folder.

pm2 start app.js

This makes sure that the app will restart if it exits due to an error.

Let's save the current process list.

pm2 save

We also need to convert it to a daemon that runs whenever the system starts:

pm2 startup systemd

As a reminder, in this tutorial, I'm using the commands for Ubuntu. If you are using any other Linux distro, you should replace systemd in this command.

We can confirm that the service is getting restarted by rebooting the server and sending a request without running app.js by hand:

sudo reboot

After sending a request as we did earlier, you should be able to see the hello world message.

Conclusion

In this tutorial we started from scratch, rented a server for ourselves, connected to it, and configured it in a way that it serves our Node.js app from port 80.

If you have followed along and were able to complete all steps, congratulations! You can be proud of yourself, as this was not the easiest topic :). I hope that you have learned a lot. Thank you for your time.

I am planning to explore this topic further by connecting the server to a domain name, then connecting it to CircleCI for continuous integration. I'll also go through the required steps to make your Node.js/React app production ready. This post had already gotten long enough, though, so those topics are reserved for another post :)

[tutorials-website]

we’ll cover all methods of how to upgrade NodeJs to Latest version in Linux Os, Ubuntu Os, Windows 7, 8, 10, and Mac Osx using NPM (Node Package Manager) and NVM (Node Version Manager).

[holytheoristtastemaker]

Disclaimer: I’m writing about my experience with major OS (Windows 10, macOs High/Sierra, Ubuntu/Manjaro) using a Solid State Drive. It has a huge impact in term of speed and it could be different from your own experience.

Hello there. To begin with, this post isn’t about what’s the best OS for everyday programming, it could depend on the stack used, Misc programs and specially YOU, so i’ll try to describe all the good/bad things that happened during my everyday workflows.

But before that I should let you know my programming stack so you won't get confused later. I mainly use:

PHP frameworks and CMS

nodejs frameworks for frontend

react native/ionic for mobile dev

Photoshop (with CssHat) for HTML Integration, banner for mobile apps.

ms office due to my current job.[1]

Ubuntu (Unity/Gnome):

By the end of 2015 and after a good run with Windows 7 and using Ubuntu just occasionally in virtual machines I thought I would give it a shot with a daily usage so I installed the 15.10 version. back then i was programming in PHP, Java and C# (because of my Software engineering Studies), php and apache had great performances locally, same for java but used a windows 7 VM for Visual Studio, Ms Office and Adobe Photoshop, because all the alternatives (Darkable/Gimp, Open office) weren't at the same levels. I tried but the more you use them the more you notice their weak points such as ease of use, backward compatibility.

I had a good (exactly 2 years) run switching between Unity and Gnome DE (I was the n°1 hater for KDE btw), but over time and even with SSD it felt a kinda slow (I was always stuck with 16.04 LTS) and honestly, I wasn’t fan of the Ubuntu’s PPAs either and then I discovered the Hackintosh community.

macOs (10.12/10.14)

So after a hell of an installation process I managed to run macOs Sierra smoothly on a laptop that has hardware near to macbook pro late 2012 (HP elitebook 840 G1). Apps installed with one simple drag n’ drop (applies to android studio too). It run the Android Virtual Device smoother than windows 7 and ubuntu with the same laptop, i was very surprised, the memory management, the apps integration and the overall stability was so great. At that time I finished my studies so no more Java or .Net programming, and the adobe/ms office suite was a strong point compared to Linux in general so every program ran natively without the need of any VM, with our beloved Unix cli.

The only drawback I had with mac, or with hackintosh, is the system updates/upgrades it was so painful to do it breaks your system every time, I was backing up the whole bootable system image whenever I attempted to update. Because the Kexts (Kernel extensions or “drivers”) weren’t always backward compatible.

So in the end i was thinking to go back to linux again but not sure which distribution i will stick with again, I wanted a stable distro that i forgot completely about something called upgrades of “big updates”. In the meantime I give Windows 10 another shot after hearing it got better and better in the last years.

And again, after 2 years with no workflow complaints I backed up my hackintosh installation and installed the last build of windows 10.

Windows 10.

I’ll resume my experience with one line: “not great, not terrible” Compared, again, to mac os the system was very smooth in every way, snapping windows, switching virtual desktops, programs and files search in the start menu, no problem but! I already missed the unix cli. Yeah I know there’s cmder and other tools. The overall performance was okay but there was some latency when compiling node js apps. My workflow didn’t change. I used Laragon for all my php projects with phpstorm and it was perfect honestly. On the other hand Android Emulator was terrible even with 8gb or ram and ssd, mac os was handling it way better.

In the meantime I played with some linux distros in VMs and made the choice: Manjaro, KDE flavor.

Manjaro:

“You said you hated KDE right?” well yes but for a cause, one I didn’t want to bring back the Gnome memories i had with Ubuntu and second, I disliked is because its similarity in UI compared to Windows in general, 10 specially then I found how very customizable was and again i’ll resume it with one line: “everything is a widget”. So in term of UI I made my simple comfortable setup.

Now in term of programs and workflow I still use PhpStorm for my php and nodejs projects, npm and yarn installed globally and surprisingly npm run very fast compared to windows and mac; git already installed, but for my php projects I migrate all of them to docker with docker compose, majority of projects were based on Laravel, Prestashop, Wordpress and old native php apps. I managed to dockerize some of them from scratch, some with Laradock.

Java/.Net: RIP.

For mobile development there were some struggles during configuring ionic and react native’s first run but done with them quickly, no problem with android studio but the emulator “again” wasn’t that good as mac os, but not that bad like windows. And I discovered a helpful package that cast my connected android device to my screen and it’s shown as a virtual device but a physical one, called scrcpy from the genymotion team!

And finally these are just some of the benefits why I picked manjaro:

No big breaking updates.

A rolling release distro.

Fast security patches.

The Great Arch User Repository (AUR)

Snap and Flatpak support (but why?)

Very stable.

But still there are some drawback, linux’s ones in general:

Still needing photoshop and lightroom.

Ms Office for work purpose (Managed to use Web version since we have ms365 but still miss Excel for heavy use)

Conclusion:

Finally and personally I’ll stick with linux for these main two reasons: native support for docker (future projects could be deployed with it) and the unix environment similarity to production servers (cli, ssh and packages’ configuration). I understand many of you will disagree for many things said in the post but that’s okay! because, finally, we choose what will help us to give the most of us in terms of productivity.

Thank you all for reading the most boring post ever made on Dev.to platform! I would gladly hear from you some of your thoughts and experiences as well. Thanks again! [1]

10 Free Software

beginning with this edition of the free software series and future episodes to come we'll take a look the best free and open source programs for your computer in short when you see the term open source software it means that its source code is freely available for users to inspect modify and distribute the software to anyone for any reason but so many free and open source programs that are actually grade coming up I will show you ten of our personal favorites many of which you've heard me discuss previously in other videos they're all well-established trusted and completely free let's get started [Music] first up is Libre Office this office suite released in 2011 is a great alternative to Microsoft Office the Microsoft Word and Excel alternatives have improved quite a bit over the years when opening and converting those file formats included with LibreOffice is writer which has many of the same features as Microsoft Word calc is similar to excel impress can be used instead of PowerPoint draw is a vector graphics editor and math can be used to create and edit mathematical formulas LibreOffice is available for Windows Mac and Linux there are two versions available for download there's one for early adopters that want the latest features and their other one is their stable release with less bugs developed by the Mozilla Foundation way back in 2002 the open source Firefox browser is still one of the most popular browsers available it has a ton of add-ons and extensions that enhance your browsing experience you can sync between your desktop and mobile devices and includes an excellent manager for bookmarks other browsers that use variants of the Firefox source code include water Fox and the privacy and security focused tour browser the Firefox web browser is available for Windows Mac and Linux various distributions of Linux Firefox is often the default web browser next up is OBS studio released in 2012 the screen recorder is available for Windows Linux and Mac it's very popular for streaming video games and other live content recordings can also be saved to your computer to be imported into your favorite video editor if you have an older PC with low system specs you may encounter lag for most people the only true thick's for this is to upgrade your computer many users of OBS studio report that they find it to be confusing to use when starting out I'd highly recommend checking out the various tutorials available online shotcut is a great video editor for new users it was initially released in 2004 and is updated on a rig cervesas a few years ago it was the first editor I used for editing YouTube videos before switching over to Premiere Pro it includes a ton of features that are often locked behind a paywall with most free video editors including support for 4k resolutions and allows for multiple tracks on the same timeline if you've tried out other video editors shot cuts user interface may not be what you're used to for example when adding tracks to the timeline you have to click on the menu icon in the lower left then select add video track and go back in and add audio track before adding your clips on the shotcut website they include video tutorials that will teach you how to use it chalk cut is available for Windows Mac and Linux the oldest program in this video is GIMP released in 1996 this image editor is one of the best free alternatives to Photoshop before we go any further many of the free and open source programs offered depend on the donations of others for development if you'd like to donate to any project you'll often see a donate button near the top of their website with Jim it's to the right of tutorials let's move on GIMP supports layers and includes tools for retouching your photos or creating brand new images from scratch in the past year GIMP has received a major upgrade making it more useful including cosmetic changes that make it look better I personally prefer the dark theme but if you don't here's how you change the theme go to edit and select preferences go down to the interface section and select theme your choices are dark which is what I'm using right now grey light and system which is way too bright if you want to check out gimp it's available for download on Linux Mac and Windows share X is one of the best screenshot utilities ever to be created it was initially released in 2007 and at this time is only available for computers running Windows 7 or newer with so many features and ways to capture any portion of your screen it makes the new screenshot tool in the latest version of Windows 10 look pathetic it's quite simple to use just go to capture in the left pane and select your screenshot method for simple tasks you can even use chair X to record your screen otherwise you're better off using OBS studio if you select web page capture it works great to capture an entire webpage at the top just enter the URL of the webpage you'd like to capture in this example I'll just use the share X website click on capture when it's done click upload with every screen capture method at the top you have various ways save upload and mark up your images blender is a 3d computer graphics toolset released in 1998 it's been used to create animated films video games visual effects and a whole lot more some of its features include 3d modeling raster graphics editing rigging and skinning and even includes a video editor blender does have a high learning curve and the user interface will be overwhelming for first-time users so I'd recommend checking out the various tutorials on the blender website when you're getting started using it blender is available for Windows Mac and Linux if you're a programmer Adam is a source code editor with support for plugins written in nodejs and embedded get control released in 2014 it's available for Windows Linux and Mac with thousands of themes and open source packages to choose from to change the look and feel of atom it includes developer tools and with its user-friendly layout it's really easy to use especially when analyzing code it's a definite step up from the standard notepad unlike most of its competitors it's truly open-source the VLC media player has been around since 2001 and will play just about any audio or video file format it's available on all major platforms including apps for both Android and iOS its user interface has been described by many people as being clunky when compared to other media players but at least it's ad free has no spyware and just works great once you get used to it VirtualBox released in 2007 allows you to create and manage guest virtual machines running other operating systems on your computer setup can be confusing for new users that's why I created a beginner's guide on this channel using the Linux distro Ubuntu as an example you can install other operating systems using the same steps just adjust the memory and CPU as needed if you experience any issues especially on older pcs you may need to go into your BIOS and enable virtualization VirtualBox is available for download on Windows Linux and Mac thanks for watching all links are in the description if this video is useful for you give it a thumbs up and share with others what is your favorite free and open source software let us know about it in the comments and if you haven't done so already subscribe and click the Bell icon to stay up to date with the latest free software and other tech related stuff from tech gumbo

Temas personalizados, emojis, sonidos y cualquier activo de tu empresa. etc… Para realizar este articulo usamos un servidor con Ubuntu 18.04 instalado.  

Instalar un servidor Rocket.Chat

Antes de instalar el servidor Rocket.Chat actualizamos nuestro sistema. apt update && apt upgrade Rocket.Chat requiere un servidor de base de datos MongoDB, versión 3.2 o superior. Para instalar la ultima versión de MongoDB debemos agregar el repositorio correspondiente. apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4 echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list Instalamos MongoDB. apt update && apt install -y mongodb-org curl graphicsmagick Ahora debemos crear un archivo especifico para que MongoDB inicie como servicio. nano /etc/systemd/system/mongodb.service Copia y pega en el archivo lo siguiente. Description=High-performance, schema-free document-oriented database server After=network.target User=mongodb ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf WantedBy=multi-user.target Guarda el archivo y cierra el editor nano. Recargamos los demonios. systemctl daemon-reload Iniciamos MongoDB y habilitamos su inicio con el sistema. systemctl start mongodb systemctl enable mongodb   Bueno... ya tenemos el servidor de bases de datos en marcha, así que continuamos. Rocket.Chat requiere que tengamos instalado Node.js (se recomienda la versión 8.11.3) y el gestor de paquetes npm, procedemos. apt -y install node.js apt install npm build-essential npm install -g inherits n && n 8.11.3 Agregamos un nuevo usuario (rocketchat) para no utilizar Rocket.Chat como root. useradd -m -U -r -d /opt/rocketchat rocketchat Cambiamos al usuario que acabamos de crear. su - rocketchat Descargamos la última versión estable de Rocket.Chat. curl -L https://releases.rocket.chat/latest/download -o rocket.chat.tgz Descomprime el paquete. tar zxvf rocket.chat.tgz Cambiamos el nombre de la carpeta de la aplicación. mv bundle rocketchat Nos movemos de directorio e instalamos las dependencias necesarias. cd rocketchat/programs/server npm install Establecemos las siguientes variables (con tu dominio real). cd /opt/rocketchat/rocketchat export ROOT_URL=http://tudominio.es:3000/ export MONGO_URL=mongodb://localhost:27017/rocketchat export PORT=3000   En este momento ya tenemos todo preparado para iniciar nuestro servidor chat. node main.js Si todo a salido bien, veras una pantalla similar a esta... +-----------------------------------------------------------------------+ | SERVER RUNNING | +-----------------------------------------------------------------------+ | | | Rocket.Chat Version: 1.2.1 | | NodeJS Version: 8.11.3 - x64 | | Platform: linux | | Process Port: 3000 | | Site URL: http://tudominio.com:3000/ | | ReplicaSet OpLog: Disabled | | Commit Hash: 202a465f1c | | Commit Branch: HEAD | | | +-----------------------------------------------------------------------+ Para que Rocket.Chat se inicie como servicio sigue los pasos siguientes. nano /etc/systemd/system/rocketchat.service Agregamos lo siguiente (asegúrate de insertar el nombre de tu dominio). Description=RocketChat Server After=network.target remote-fs.target nss-lookup.target mongod.target ExecStart=/usr/local/bin/node /opt/rocketchat/rocketchat/main.js Restart=always RestartSec=10 StandardOutput=syslog StandardError=syslog SyslogIdentifier=nodejs-example #User= #Group= Environment=NODE_ENV=production PORT=3000 ROOT_URL=http://tudominio.com MONGO_URL=mongodb://localhost:27017/rocketchat WantedBy=multi-user.target Guarda el archivo y cierra el editor. Reinicia el demonio. systemctl daemon-reload Iniciamos Rocket.Chat y habilitamos su inicio con el sistema. systemctl enable rocketchat systemctl start rocketchat Ya podemos acceder a Rocket.Chat y completar la instalación. Desde tu navegador web favorito accede a la siguiente url. http://tudominio.com:3000 El asistente de instalación te guiará a través de la configuración desde su usuario administrador. Una vez ya lo tengas todo instalado y configurado, te recomiendo que descargues la aplicación de escritorio para interactuar con el resto de usuarios. Al iniciar la aplicación de escritorio por primera vez te pedirá la url del servidor de chat al que te quieres conectar. La url "https://open.rocket.chat" es el chat de la comunidad Rocket.Chat.
