How to Optimize Your Offshore SSD VPS for Maximum Efficiency

Having a well-optimized Offshore SSD VPS Hosting Solution is crucial for maintaining high performance, security, and cost-effectiveness. By implementing the right strategies, you can maximize the efficiency of your SSD VPS Servers while ensuring a seamless experience for your users. Here’s a step-by-step guide to help you achieve optimal performance.

1. Select the Right Operating System

Choosing an efficient OS like Linux (Ubuntu, CentOS, or Debian) can reduce resource consumption and improve server stability. Opt for minimal installations to avoid unnecessary processes that slow down your Offshore VPS Hosting Services.

2. Keep Software and System Updated

Regular updates enhance security and efficiency. Ensure your Offshore VPS Hosting Solutions receive the latest OS patches, security fixes, and software upgrades to maintain peak performance.

3. Optimize SSD Performance

Since SSDs provide high-speed storage, enabling TRIM support and reducing unnecessary write operations will extend their lifespan and enhance server performance. Using a lightweight file system like ext4 or XFS can further optimize storage efficiency.

4. Implement Caching Mechanisms

Caching reduces server load and speeds up content delivery. Tools like Memcached, Redis, or Varnish can significantly improve the responsiveness of your SSD VPS Servers by storing frequently accessed data.

5. Use a Lightweight Web Server

Switching to a high-performance web server like Nginx or LiteSpeed can enhance efficiency by handling more simultaneous connections with fewer resources. This optimization is essential for Offshore VPS Hosting Services that deal with heavy traffic.

6. Optimize Database Queries

Inefficient database queries can slow down your server. Use indexing, query caching, and database optimization tools to ensure fast and efficient data retrieval. MySQL tuning with InnoDB adjustments can also improve performance.

7. Strengthen Security Measures

Securing your Offshore SSD VPS Hosting Solutions is critical. Use firewalls (like UFW or CSF), SSH key authentication, and regular malware scans to prevent vulnerabilities and unauthorized access.

8. Leverage a Content Delivery Network (CDN)

A CDN reduces latency and speeds up global content delivery by caching and distributing resources across multiple locations. This reduces the direct load on your Offshore VPS Hosting Solutions.

9. Monitor Resource Usage

Tracking CPU, memory, and disk space usage is essential for identifying bottlenecks. Use monitoring tools like Nagios, Zabbix, or htop to ensure your SSD VPS Servers operate efficiently.

10. Optimize Bandwidth Usage

Reduce data transfer costs and improve performance by enabling Gzip or Brotli compression, minimizing HTTP requests, and optimizing website images. This ensures efficient bandwidth usage for your Off shore SSD VPS Hosting Solutions.

Conclusion

By applying these optimization techniques, you can enhance the efficiency, security, and performance of your Offshore SSD VPS Hosting Solutions. A well-maintained VPS ensures smooth operation, better user experience, and cost savings. Start implementing these strategies today to get the most out of your hosting solution!

The Ultimate InterServer WordPress VPS Hosting Review

In this article, I’m going to show you how to make a WordPress Website on InterServer WordPress VPS Hosting (Virtual Private Server).

At the same time, I will share with you my honest and unbiased review of this service.

Unlike other reviews, this is going to be a spontaneous report of an ongoing experience that summarizes the impressions and opinions I have before, during, and afterthe purchase and the use of the service.

Why InterServer?

In the ultimate guide of How to Make a Website, I strongly recommended established companies that have good experience with hosting and InterServer was one of them.

InterServer is an American hosting company and a domain registrar that has been in the industry for more than 21 years.

Although a lot has changed since then, these long years must have enriched its experience.

Today, the company provides varied services ranging from simple hosting plans intended for small businesses to advanced plans for giant companies.

I liked this because it is a great indicator that this is the hosting that one can grow and stay with for a long time.

1. My First Impressions: Before Selecting a Package

The website of InterServer looks professional: The combination of the main colors, white and blue, plus the organization of the information makes the understanding of the website structure and main services they provide easy.

At this time, I see that they are offering a 65% OFF discount ($2.50 / month), plus a special coupon (PENNYDEAL) that allows you to get their shared hosting for $0.01 the first month. The offer is made to encourage new visitors to buy and try their services.

I already got their shared hosting plan, and now I want to try their WordPress VPS Hosting.

I’m choosing this option to benefit from the power and the speed it provides.

My choice of a VPS over a shared hosting will result in a faster and stronger website: And after all, VPS to Shared Hosting is like a private car to a public bus.

Promises & Guarantees

On the purchase page, InterServer promises that my WordPress Website will be ready in 20 minutes and says that the price starts from $6 per month.

InterServer also promises high performances and speed: It states that their VPS is optimized for WordPress, making it more powerful to WP than an ordinary VPS.

Furthermore, they guarantee:

1. Free Migration Service (Migrate your website from a place to another)

2. High-performance storage. (Optimized for WP, fast and responsive)

3. Instant Provisioning (Activates in a few seconds)

4. 99,99% Uptime Guarantee (Website available everywhere in the world, all the time)

5. Easy Control Panel

6. Multiple Language Servers (PHP, MySQL, Perl, Python, Ruby…etc.)

7. Flexible Software Options (full root access to install any software.)

My Choice

There's a bar in the middle of the page to customize the VPS: If you want more power, you can move it to the right. But, the more you do, the more the price rises.

As a starter, 1 core, 2048MB, 30GB SSD, and 2TB transfer are more than enough for my project.

At a later time, If I ever need more resources for my website, I will always have the option to upgrade them.

Now, with this configuration and at this price, it’s worth it. Yet I think it would have been more appealing if it was a little bit cheaper than this.

2. Ordering the VPS

By clicking on BUY NOW, the configuration page shows up.

On the left side, there’s a table that can be used to customize the VPS before ordering it.

The table allows you to choose:

1. The platform of the VPS (Virtuozzo, KVM, or HyperV),

2. The location of the VPS (New Jersy, Los Angeles, or Equinix NY4),

3. How many slices you need (1 or more, and up to 16),

4. The operating system (CentOS, Debian, Fedora, OpenSUSE, Ubuntu, VzLinux, and Windows),

5. The version of the operating system,

6. The control panel (None, DirectAdmin, or cPanel),

7. The Hostname and Root Password,

8. The Coupon Code

And it indicates the overall price.

I will not change a lot here; I will only enter the Hostname (Domain Name) and a Root Password.

To get a price reduction of $0.01 for the first month like me, you can use the coupon code PENNYDEAL before you proceed.

On the right side of the screen, there’s a table titled VPS availability.

As you can see in the picture below, VPSs are not available in Los Angeles right now. I will stick with New Jersey.

Below it, there’s a table that indicates the current VPS information:

When you click on proceed, you will be directed to the confirmation page, where you will be able to review your order.

You will also be asked to read and accept the Terms and conditions as well as the Privacy Policy.

After that, you will be able to pay for the service.

3. After Purchase: Let’s Test the Promises

VPS Activation

Once I placed the order, I saw a progress bar telling me to hold on while building the server.

I noted the starting time to see how many minutes it will take.

Surprisingly, in about 60 seconds I had my server up and running.

Linking the VPS to the Domain Name

Now that I have a unique VPS IP, I need to link it to my domain name to be able to access my website through the URL.

Image 1: IPV4 ADDRESS

To do that, I just have to add an A record in the DNS configuration page of my domain name (image 2) and set the hostname to the hostname I chose (vps.clevious.com), and the IPV4 ADDRESS (image 1) to the unique IP address I got.

Rhel Desktop Iso

Red Hat Enterprise Linux (RHEL) is a Linux distribution developed by Red Hat and targeted toward the commercial market. Red Hat Enterprise Linux is released in server editions for x86, x8664, Itanium, PowerPC and IBM System z architectures, and desktop editions for x86 and x8664 processors. Red Hat Enterprise Linux, or RHEL, is the go-to enterprise-level Linux distribution for those customers who want support from a vendor.

Redhat Linux is one of the many Linux distributions and one of few open-source OS with enterprise class of technical support. Indeed, it’s well backup by many big boys such as IBM, Dell, HP-Compaq, Oracle, etc. Apart from that, a scale-down version of Fedora Core is also selected for well-known

One-Laptop-Per-Child project (OLPC)

! OLPC is a nice and caring idea of developing $100 laptop (XO-1 or Children’s Machine) for children around the world, especially to those in developing countries, to provide them with access to modern form of knowledge and education! Unlike Windows Vista or its predecessor, you neither need to really pay for a genuine Redhat Linux CD nor you’ll see high-tech hologram printed. Redhat Linux is free-of-charge OS, unless you need to access their technical support or using Redhat Enterprise Linux. Having say that, you can easily and freely download Redhat Linux CD ISO image from its FTP server. Although, development of the free version Redhat Linux has been discontinued after the release of Redhat Linux 9. Then, it’s Fedora Core – a merger between the Redhat Linux and old Fedora Linux projects in September 2003! Anyway, Redhat Inc (NYSE:RHT) sponsorship is ensuring that Fedora Core will continue available for free download and installation.

Centos 6 Minimal Iso

As a home user, there might be little or not problem at all by using the most up-to-date Linux distribution, such as Fedora Core 7. However, upgrade is not always an easy job for Linux administrators, who are maintaining legacy application servers running on old Redhat Linux distribution! So, one of the Linux administrator responsibilities is to ensure all the Linux installation CDs or ISO images are securely maintained and regularly backup. If you have lost track of them, you’ll appreciated if someone or somewhere still have a copy for download!

Here are the last resources – the official archive of Redhat Linux CD ISO images available for download from Redhat file servers. Also included are Redhat Linux LiveCD for OLPC project and the latest Fedora Core 7 download links:

Thank you for the access to these ISO files for Redhat 7.2. I am making an effort to use Kylix 3 and it was certified on this version. All the best in your walkings!

This site is great for redhat iso’s and even legacy redhat iso’s here lately I have been searching for a really really old copy of redhat linux 2.5, does anyone know where I can get it?

thx

Dears, Am downloading Redhat 7.2 , thanks for that , but i want to know which specific files that should i download and how to mount it ?

If you’re looking for English version, then browse to “en”, “iso”, “i386” folder.

Depends on how you want to use the ISO files, e.g. if install on physical machine, then you should burn the ISO file to disc. To read the ISO file on Linux, you can try this.

Hi, thanks for the iso files!!

thanks man! been looking for a site like this one, glad i found it. More power!

I want redhat 6.3 64bit

THANKS

Hi there, I have downloaded and tried installing several different iso’s of redhat, versions 8 and 9. Unfortunately, my computer will not boot from the CD; other CD’s will boot however, so I know the drive is good. I have a disc one iso for version that I downloaded a few years back and it runs but I can’t find disc two to continue the installation. If it helps, my computer is a Compaq desktop with a i845 chipset. It does meet the requirements for the system but for some reason, I can’t get any of the iso’s I’ve downloaded to work! Please help!!!!!

Thank you!

First of all, did you verify the MD5 file checksum of the ISO images you’ve downloaded?

If the file checksum is valid, then I suspect you didn’t “burn” the ISO image correctly onto the CD/DVD-ROM.

Otherwise, the images hosted by the official site might have corrupted.

Install Specific Version of MySQL 8 using YUM

We have many ways to install MySQL on linux machines such as source, binary and so on. But most of the Engineers always prefer default package managers (yum for RPM-Based distributions and apt for DPKG-Based distributions) for its ease of use and it can resolve all dependencies on its own. And of course, it is not possible to use package managers in environments where the internet is not allowed, but this is a different case.  At some point, we need to install exactly specific version of MySQL for the following cases To create Production Replicas  To simulate an Production Issue on similar kind of environment To configure Disaster Recovery(DR)/UAT Setup Compatibility with opensource tools ( Eg , Xtrabackup compatibility ) But following the instructions from MySQL Documentation for installation using yum always leads to the installation of the latest version released. At the time of writing this blog, the latest release is MySQL 8.0.22. Following the documentation steps resulted in installation of the same. Definitely, we can install other versions of MySQL using RPM files. But it is quite tough at times because of its dependencies or conflicts with any other older version packages. So, in this blog post, we will look at how to install a specific version of MySQL using yum. All the following steps are tested in CentOS 7 and it requires sudo privileges. Setting up Yum Repository The below command will enable the yum repository required for the installation of MySQL rpm -Uvh https://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm Disabling all repos in MySQL It is to disable repos for all versions of MySQL. sed -i 's/enabled=1/enabled=0/' /etc/yum.repos.d/mysql-community.repo To install MySQL 8 of particular minor version, let’s say 8.0.20 , we can execute the following command yum --enablerepo=mysql80-community install mysql*8.0.20* So, the general command will be like yum --enablerepo=mysql80-community install mysql*8.0.X* Where X is the minor version that you want Or else if you want to install the latest version, just go with the below command. It will install the latest version available at that time. yum --enablerepo=mysql80-community install mysql-community-server That’s it if the above command succeeds. We will get the required version successfully installed on the server. 4. Start the MySQL service Use the below service command to start up the MySQL service service mysqld start 5. Get the temporary password in the error log By default, MySQL will generate a temporary password for root user and it will be in the error log. So, to get the temporary password from error log use the below command. grep "temporary password" /var/log/mysqld.log The sample output would be like: [root@ha mydbopslabs]# grep "temporary password" /var/log/mysqld.log 2020-12-10T14:12:49.940127Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: 7y:ztnVKwh7q [root@ha mydbopslabs]# 6) Login the MySQL using root user with the temporary password mysql -p'$temporary password' 7) On successful login, we should reset the root user password as the first thing. Otherwise, we cannot execute any commands until we reset the password. we will get the warning like below mysql> show schemas;ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.mysql> To reset the root user password, execute the below query on mysql prompt. alter user 'root'@'localhost' identified by 'strong password'; Sample query be like mysql>mysql> alter user 'root'@'localhost' identified by '[BX.D"7s!c';Query OK, 0 rows affected (0.22 sec)mysql> Once it is done, our MySQL setup is ready to use. For fine tuning of MySQL to handle production work load, refer our presentation Fine Tuning of MySQL 8.0 which was taken at Mydbops Database Meetup. Also, look our other blogs that explores the coolest features of MySQL 8.0 which greatly helps for Database Administrators and Developers. https://mydbops.wordpress.com/2020/12/12/install-specific-version-mysql-8-using-yum/

こんにちは。GMOリサーチでインフラを担当しているオカモトです。 コロナの影響で引きこもり生活が続く中、皆様いかがお過ごしでしょうか。 今回、Googleが先日公開した「Tsunami」というオープンソースのセキュリティスキャナーを試してみたのでその内容をご紹介します。 １．Tsunamiって何？ Tsunamiは、2020年6月18日木曜日（現地時間）にGoogleがオープンソースのプロジェクトとして公開したセキュリティスキャナーです。 GoogleではGKE（Google Kubernetes Engine）を使ってインターネットからアクセスを受けているシステムの脆弱性診断にTsunamiを使っているそうです。 ・Tsunamiのリリースに関する記事は以下のURLから確認できます。 Google Open Source Blog https://opensource.googleblog.com/2020/06/tsunami-extensible-network-scanning.html Tsunamiは以下の目標・理念を掲げて開発を進めているそうで、超大規模なシステムを高速にスキャンするような用途でも使いやすいソフトウェアを目指しているようです。 Tsunami supports small manually curated set of vulnerabilities（手動でリストアップされた少数の脆弱性に対してのスキャンをサポート）Tsunami detects high severity, RCE-like vulnerabilities, which often actively exploited in the wild（遠隔からのコード実行のような緊急度の高い脆弱性を検知する）Tsunami generates scan results with high confidence and minimal false-positive rate（誤検出率を最小限に抑えた信頼性の高いスキャン結果を生成する）Tsunami detectors are easy to implement.（脆弱性の検知器は簡単に実装できる）Tsunami is easy to scale, executes fast and scans non-intrusively.（簡単にスケールできる。高速に実行��れ、対象システムに侵入せずにスキャンする）２．Tsunamiの仕組み 公式の資料によるとTsunamiの脆弱性診断の流れは以下のような感じで進むそうです。 出典: Tsunami Scan Orchestration https://github.com/google/tsunami-security-scanner/blob/master/docs/orchestration.md 大きく分けて、Reconnaisance（調査/偵察）とVulnerability Verification（脆弱性の検証）の2つのステップで実行されるそうで、各ステップの役割は以下の通りになります。 Reconnaisance（調査/偵察） Reconnaisance（調査/偵察）のステップでは、ポートスキャンとフィンガープリントの2つのフェーズで対象システムに関する情報を可能な限り収集します。 ＜ポートスキャン＞ 対象システムの開いているポート、使われているプロトコル、ネットワークサービスなどを検出するフェーズ。 車輪の再発明をしないために、nmapやmasscanなどの既存のソフトウェアを内部で利用したプラグインを使うことを想定しているようです。 デフォルトではnmapのプラグインが使えます。 ＜フィンガープリント＞ 検知したポートで動いているサービスやウェブアプリケーションを検出するフェーズ。 1つのポートで複数のウェブアプリケーションが動いているような場合でも、それぞれのウェブアプリケーションを識別することを目指しているようです。 （例、TCPポートの443でリバースプロキシとしてnginxが動いている状態で、/blogではWordPress、/forumではphpBBが動いているというような構成）。 残念ながら今はまだ実装されてないみたいです。 Vulnerability Verification（脆弱性の検証） Vulnerability Verification（脆弱性の検証）のステップでは、前のステップで収集した情報に基づいて、脆弱性検知のプラグインを並列に実行して対象に脆弱性がないか検証します。 脆弱性検知のプラグインは、基本的には1つの脆弱性に対して1つのプラグインとして実装されることを想定しているようです。 また将来的な構想として、脆弱性検知のプラグインをJavaで実装するほかにPythonやGoなど別の言語でも実装できるようにしたいそうです。 ※現在公開されているTsunamiは開発者に試してもらうことを目的としたPre-Alpha版なので、将来的に仕様に大きな変更が入る可能性があります。 ３．Tsunamiを実際にインストールしてみた 今回は以下の環境のサーバーを使って試してみました。 CentOS Linux release 7.7.1908 (Core) 3.10.0-1062.4.1.el7.x86_64 ① 必要なパッケージのインストール 以下のバージョン以降のnmapとncrackが必要となるので、それぞれ公式サイトよりバイナリ及びソースコードをダウンロードしてインストールします。 nmap = 7.80 ncrack = 0.7 nmapとncrackの最新安定版はこちらからダウンロードできます。 ● nmap(binary/source) https://nmap.org/download.html ● ncrack(source) https://nmap.org/ncrack/ また、今回のテスト環境ではncrackのコンパイルのためopensslのバージョンを上げる必要があったので以下のバージョンのopensslもインストールしています。 お使いの環境によってはその他にも必要なものがあるかもしれません。 #

The Good, the Bad and the Unknown — Bluehost Review In 2019

BlueHost is one of the oldest and most reputable web hosting providers accessible as my review in 2019. This Bluehost evaluation depends strongly on information, as well as on the general experience with their hosting characteristics and customer support.

In short, all Bluehost plans give their clients 24/7 live chat, unlimited bandwidth, and at least 5 email accounts. Similarly to many other web hosting companies, they too offer their users a free domain for the first year. Their plans start from $2.75/mo and include improved security, backups, and SSL certificate. These help keep your website secure and protect.

Overall, their performance was great. Bluehost is obviously at the top with its uptime (99.99 percent) and a quick load time of 0.41ms. Read all of the “Advantage” and “Disadvantage” below:

First of all, we should know about the history of Bluehost.

History of Bluehost?

Most of the individuals who heard about any hosting business probably learned about Bluehost.

Podcasters and internet marketing leaders love to encourage it, but is it a nice thing?

Founded in 2003, Bluehost is a private hosting company owned by Endurance International Group. With its sister hosting HostMonster, FastDomain, and iPage, the group owns almost two million domains. The service specialties are based in Provo, Utah, Bluehost VPS and specialized server hosting plans.

How Good is Bluehost Hosting?

The biggest selling point of Bluehost is, well, their selling point.

Bluehost pricing (beginning at around $2.95) is one of the lowest on the market and comes standard with all the fundamental characteristics that a shared hosting supplier might want.

They are worth comparing against other similar budget hosts as they offer a wide variety of plans with certain niche advantages. You may want to keep an eye out for a few things that our researchers found, however. Uptime and speed are considerably smaller than most rivals (particularly higher-priced competitors) and Bluehost’s customer service is not as helpful as one would have hoped.

General Info & Hosting Overview of Bluehost Review

Let’s see Bluehost Review In 2019

OVERALL RANK: Rated #1 out of 32 web host

speed: 406ms (Average from December 2017 to March 2019)

UPTIME:99.99% (Average from December 2017 to March 2019)

SUPPORT:24/7 Live ChatAPPS: WordPress, Joomla, Drupal, and some website builders

FEATURES: Unmetered bandwidth and storage, email accounts, free domain 1st year hosting

PLANS: Shared, Cloud, VPS, and Dedicated Servers

SITE TRANSFER: Not free pricing:

Starting at $2.75/mo (renews at $7.95/mo)

Why Choose Bluehost?

• Bluehost is awarded #1 for WordPress by WordPress.org since 2005 • Heavy focus on WordPress with WordPress installed by default on all new accounts • Custom-branded cPanel with all of the industry-standard features • Affordable cloud hosting with solid performance/reliability • Optimized plans specifically for WordPress and WooCommerce • Free & paid integrated SSL certificates for eCommerce websites • Personal & direct customer phone support based in the US • Numerous add-ons available, such as G Suite, Spam Experts, SiteLock, etc.

Key Features We Like On Bluehost Hosting

• Default support for PHP, Perl, Python, Ruby/Rails, & MySQL on Apache with the ability to install any other web server extensions required by developers or programming teams. • Fast hardware with SSD storage and real-time analytics that monitor website user traffic. • Immediate provisioning with no need to spend hours installing the OS and setting up the server. • Inclusion of Dedicated IP addresses and cPanel/CentOS license saves money over other companies. • Easily organize, edit, and manage databases directly on the server with Bluehost’s custom-designed database manager.

WHAT WE DON’T LIKE:

• VPS plans max-out at 4 CPU cores & 8 GB RAM, forcing an upgrade to dedicated servers.• Cloud Hosting plans are cheaper and more feature-packed, with higher capacity to support traffic spikes on a scale, while offering comparable hardware allocations, developer instruments, and third-party add-ons. • Configuration settings for sophisticated web page caching & HTML / JavaScript compression may be complicated for inexperienced users and involve live testing on manufacturing locations to be optimized.

What Are The Disadvantage of Bluehost

• Monetizes your site by injecting ads onto the 404 pages (although this can be disabled) • Basic hosting plan only allows you to host 1 website • Weebly site builder is pointless • Average speed & reliability scores from our performance testing on shared hosting plans • Uses MOJO Marketplace which includes a lot of bloatware/upsells • Charges $149 for migrating your existing website over to them • The cost of additional dedicated IP addresses can be expensive • Customer support via email tickets was discontinued • No prorated refund after 30 days

Do We Recommend Bluehost Hosting

yes, we do

Bluehost ranked at or near the top for both uptime and load times for more than a year.

They also provide strong safety help, money-back guarantee, and a lot of user-friendly apps, all for one of the lowest rates in the industry ($2.75/month).

They’re not perfect, however. Renewal prices will occur following the closing of the introductory price. And they pay extra for site migrations, which other hosts throw free of charge.

But overall, for a good value, Bluehost delivers a strong performance.

Instalar Grafana en CentOS 8

Instalar Grafana en CentOS 8 y CentOS 7. Grafana, es una de las mejores herramientas para monitorizar servidores que puedes encontrar, tiene unas propiedades únicas para ser de código abierto. No pienses que estamos ante una herramienta común, no no, de eso nada. Solo te digo que gigantes como eBay, Paypal o el mismo RedHat, utilizan Grafana para monitorear sus servidores. Es una herramienta imprescindible si quieres controlar tus servidores de manera robusta y escalable. Como ya comentamos en un articulo anterior, el nuevo panel de control web, Plesk Obsidian, lo integra de serie en sus instalaciones. Es muy, muy bueno. Grafana tiene otra interesante particularidad, nos permite optar por vincularlo con bases de datos de series temporales como InfluxDB o Prometheus, o con bases de datos relacionales como MySQL, MariaDB o PostgreSQL. En este articulo vemos como instalar Grafana en tu servidor o VPS.  

Instalar Grafana en CentOS 8 o CentOS 7

Comenzamos actualizando el servidor. sudo yum update Agregamos el repositorio de Grafana. nano /etc/yum.repos.d/grafana.repo Copia y pega lo siguiente: name=grafana baseurl=https://packages.grafana.com/oss/rpm repo_gpgcheck=1 enabled=1 gpgcheck=1 gpgkey=https://packages.grafana.com/gpg.key sslverify=1 sslcacert=/etc/pki/tls/certs/ca-bundle.crt Guarda el archivo, cierra el editor, y actualiza el sistema. sudo yum update Instalamos Grafana. sudo yum install grafana Una vez concluya la instalación, puedes comprobar el servicio con sus rutas. cat /usr/lib/systemd/system/grafana-server.service ejemplo... Description=Grafana instance Documentation=http://docs.grafana.org Wants=network-online.target After=network-online.target After=postgresql.service mariadb.service mysqld.service EnvironmentFile=/etc/sysconfig/grafana-server User=grafana Group=grafana Type=notify Restart=on-failure WorkingDirectory=/usr/share/grafana RuntimeDirectory=grafana RuntimeDirectoryMode=0750 ExecStart=/usr/sbin/grafana-server \                                                         --config=${CONF_FILE} \                                                         --pidfile=${PID_FILE_DIR}/grafana-server.pid \                                                         --packaging=rpm \                                                         cfg:default.paths.logs=${LOG_DIR} \                                                         cfg:default.paths.data=${DATA_DIR} \                                                         cfg:default.paths.plugins=${PLUGINS_DIR} \                                                         cfg:default.paths.provisioning=${PROVISIONING_CFG_DIR} LimitNOFILE=10000 TimeoutStopSec=20 WantedBy=multi-user.target Según nos indica el ejemplo anterior... Los binarios de Grafana están en /usr/sbin/grafana-server. El archivo que define las variables de entorno las podemos encontrar en /etc/sysconfig/grafana-server. El archivo de configuración es a través de la variable CONF_FILE. El PID del archivo lo determina la variable PID_FILE_DIR. Las rutas del registro, datos, complementos, y más... también están indicadas por las variables. Puedes ver las variables en: etc/sysconfig/grafana-server ejemplo... GRAFANA_USER=grafana GRAFANA_GROUP=grafana GRAFANA_HOME=/usr/share/grafana LOG_DIR=/var/log/grafana DATA_DIR=/var/lib/grafana MAX_OPEN_FILES=10000 CONF_DIR=/etc/grafana CONF_FILE=/etc/grafana/grafana.ini RESTART_ON_UPGRADE=true PLUGINS_DIR=/var/lib/grafana/plugins PROVISIONING_CFG_DIR=/etc/grafana/provisioning # Only used on systemd systems PID_FILE_DIR=/var/run/grafana Puedes ver en el ejemplo anterior, que al instalar Grafana ya se creo un usuario (grafana). Vale, continuamos... Iniciamos Grafana y verificamos el servicio. sudo systemctl start grafana-server sudo systemctl status grafana-server Felicidades, ya tiene a Grafana corriendo en tu sistema. No te olvides de abrir el puerto correspondiente. sudo firewall-cmd --add-port=3000/tcp --permanent sudo firewall-cmd --reload   Interfaz de usuario de Grafana El puerto por defecto de Grafana es el "3000", por tanto desde tu navegador web favorito puedes acceder así... http://ip-del-servidor:3000/ http://localhost:3000/ Nos aparece la pantalla de inicio de sesión, por defecto el usuario y la contraseña es "admin".

Iniciar sesión en Grafana La aplicación te pide que modifiques la contraseña por defecto.

Modificar el password en Grafana Accedemos a la pantalla predeterminada por defecto de Grafana.

Pantalla principal de Grafama La url de inicio de sesión en Grafana es la siguiente: http://ip-del-servidor:3000/signup http://localhost:3000/signup Si tu eres el sysadmin, y no quieres que nadie más tenga acceso, algo recomendable (ni intentar registrarse), sigue los pasos que te indico a continuación. Editamos el archivo "grafana.ini". sudo nano /etc/grafana/grafana.ini Busca la siguiente linea... # disable user signup / registration ;allow_sign_up = true La modificas a false. # disable user signup / registration ;allow_sign_up = false Guarda el archivo y cierras el editor. Para concluir reiniciamos Grafana. sudo systemctl restart grafana-server En un próximo articulo aprenderemos a crear nuestro primer tablero, síguenos.   Espero que este mini articulo te sea útil, puedes ayudarnos a mantener el servidor con una donación (paypal), o también colaborar con el simple gesto de compartir nuestros artículos en tu sitio web, blog, foro o redes sociales.   Read the full article
