How to Install MongoDB 8 on Amazon Linux 2023

[fromdevcom]

In this article, I’ll be sharing the technical expertise and help you understand all that freaky on the first sight staff. There will be information about stacks, frameworks, programming languages etc., - everything that can help one understand aspects of developing tools that are commonly used in web development agencies.What is MEAN stack development?So, today we are going to talk about MEAN, not the adjective, but the abbreviation for the Javascript web development stack that consists of:MongoDB - database.Express.js - application server, used for the backend.Angular.js - web application framework, used for the frontend.Node.js - web server. The MEAN stack today is a modern and more flexible analog of LAMP (Linux, Apache, MySQL, PHP) web development stack. While LAMP requires special OS, MEAN can be developed on every OS - Windows, Mac, Linux.Technical features of MEAN technology stackMongoDB MongoDB is a document-oriented database specially created to store hierarchical data structures (documents) and is implemented using a NoSQL approach. This NoSQL approach represents a fundamental shift in the persistence strategy.The programmer spends less time writing SQL statements and more writing the map/reduce functions in JavaScript. This eliminates the huge layers of transformation logic since MongoDB initially produces the JavaScript Object Notation (JSON) format. As a result, writing of REST web services is extremely easy.Express.js Express.js is free and open-source web application framework that runs on top of Node.js. It is used for backend development. The huge step from LAMP is a transition from a traditional generation of pages on the server side to targeting single-page applications (SPA) on the client side. Express allows you to manage and route/generate pages on the server side, but other components of MEAN stack such as Angular.js turn it more into client side.Angular.jsAngular.js is frontend MVC (Model-View-Controller) framework in Javascript with an open-source software.The transition to SPA does not simply translate the MVC artifacts from the server to the client device. This is also a jump from the mentality of synchronism to the mentality of asynchronism, which is essentially event-driven. And perhaps, most importantly is the movement from page-oriented applications to component-oriented applications.Node.js JavaScript development platform for server-side. It transforms JavaScript from a highly specialized language to general-purpose language. Node.js replaces Apache from the LAMP stack. But Node.js is much more than just a web server. In fact, the finished application is not deployed on a separate web server; instead, the web server itself is included in the application and automatically installed as part of the MEAN stack. As a result, the deployment process is greatly simplified, since the required version of the web server is explicitly defined along with the remaining dependencies of the execution time.Why we prefer using the MEAN stack over LAMP?During the last 10 years of our existence, we have always been trying to improve our development process. We rejected ineffective, slow or narrow-oriented tools and worked hard to deliver only high-quality results. We tried using LAMP and actually we still use it in some projects, but the transition to MEAN stack development is where we are heading to. Why? Here is the answer: One programming language (JavaScript) - less confusion with syntax.On AngularJS it is convenient to make rich client applications that do not require reloading of pages (MVC, event model, routing, the possibility of creating components + this killer-feature: two-way data binding).On Node.js in conjunction with Express framework, it is good to do RESTful API backend. When the server sends only the data to JSON, and the client itself is engaged in the submission. This reduces the connectivity of the client and server + simplifies the creation of a mobile application in the future (it will come in handy with the same API).

Of course, the RESTful API can be done in PHP, but the PHP process will be created and terminated with each request, spending resources on initialization, while the process on Node.js hangs in memory all the time.Asynchrony. Even the fact that any mean stack example can be implemented two times faster because of asynchrony, make us believe, that is one of the best options. Node.js does not block the current process when accessing external resources (for example, the database). This allows, among other things, to execute several requests in parallel. Node.js has a cool NPM package manager and a cool package community. Under any task, be it PDF generation or Email sending, it's easy to find a package with a concise interface and add it to your application.So with these technologies, the MEAN stack developers can build applications with higher quality in less time so that they can deliver a quick result to the customer while fewer resources are used.

Our goal is to turn clients’ ideas only to excellent results!

Data is the foundation of successful businesses in today's linked digital landscape, driving everything from decision-making procedures to consumer interactions. Organizations heavily rely on powerful database management systems to fully utilize the value of data. Microsoft SQL Server, MySQL, and MongoDB stand out among the many solutions available as three well-known names. These database systems are essential for organizing, retrieving, and storing data; yet, they each go about this in a different way and have different advantages and disadvantages.

This blog is to uncover the complexities of these three database juggernauts, comprehending what makes them special and how they cater to various needs.

Microsoft SQL Server

A game-changer in relational databases. Robust, reliable, and feature-packed, it drives apps from small projects to enterprise solutions. Join us to unveil its magic—data storage, retrieval, performance, and security.

Hardware:

Running on Windows-based hardware, Microsoft SQL Server is a dependable relational database management system (RDBMS). It can be installed on a variety of hardware arrangements, including single-server systems and clusters of powerful servers. For the best speed while processing big datasets and difficult queries, it makes use of multi-core computers, lots of RAM, and quick storage systems.

Software:

The Windows operating system-based Microsoft SQL Server has a number of editions, each suited to a particular purpose, including the Express, Standard, and Enterprise editions. In addition to SQL Server Management Studio (SSMS), Integration Services, Analysis Services, and Reporting Services, it offers a range of tools for database management. These resources support database creation, upkeep, and business intelligence.

Procedure:

For data administration and manipulation, Microsoft SQL Server adheres to the Structured Query Language (SQL) standards. SQL commands are used by users to create, update, and retrieve data. In order to improve data security and integrity, it offers stored processes, triggers, and functions for procedural logic. To maintain data availability and reliability, SQL Server also provides sophisticated tools including replication, backup and recovery, and failover clustering.

Data:

SQL Server maintains the consistency and integrity of the data by storing it in relational tables with established schemas. It supports ACID transactions, which ensure that database operations are carried out trustworthily. ACID stands for Atomicity, Consistency, Isolation, and Durability. Additionally, SQL Server makes it possible to build intricate connections between tables, which makes it easier to get and analyze data quickly.

MySQL

Is an open-source relational database management system, consists of key components that drive its functionality:

Hardware:

Popular open-source relational database system MySQL is compatible with Windows, Linux, and macOS in addition to other hardware systems. It is a versatile option for both small-scale applications and large-scale systems because it is designed to operate effectively even on basic hardware configurations.

Software:

The Community Edition and the Enterprise Edition are the two primary editions of MySQL's core system. While the Enterprise Edition offers extra tools and assistance, the Community Edition is open-source and delivers necessary features. A graphical tool called MySQL Workbench makes it easier to create, manage, and develop queries for databases.

Procedure:

Similar to Microsoft SQL Server, MySQL too employs SQL to manipulate data. Using SQL commands, users can create, change, and query databases, among other things. MySQL offers user-defined functions, stored procedures, and triggers, enabling programmers to incorporate unique logic inside the database. To improve data availability and fault tolerance, it provides replication and clustering functions.

Data:

Structured tables with predefined schemas are used by MySQL to store data. It is well renowned for performing well in read-intensive situations, making it appropriate for applications that call for quick data retrieval. Because MySQL supports ACID transactions, data consistency and durability are guaranteed. Additionally, it supports many storage engines, including InnoDB and MyISAM, each of which is tailored for a particular use case.

MongoDB

A popular NoSQL database, operates through essential components that define its functionality:

Hardware:

Leading NoSQL database system MongoDB was created to manage unstructured or partially organized data. It can be installed on a variety of hardware setups, including cloud-based settings and common hardware. The architecture of MongoDB is adaptable and can extend horizontally to handle expanding datasets.

Software:

MongoDB has both a community edition and an enterprise version, and it functions as a distributed database. MongoDB is accessed by developers through drivers tailored to their chosen programming languages. A graphical tool called MongoDB Compass facilitates query exploration and database management, making it simpler to work with the document-oriented approach.

Procedure:

The flexible schema-less method used by MongoDB differs from that of conventional RDBMS systems. Data is kept as groups of documents that resemble JSON. Users work with MongoDB by performing CRUD (Create, Read, Update, Delete) actions on documents using the MongoDB Query Language (MQL). Due to its nature, MongoDB is a good choice for applications that need quick and agile development cycles.

Data:

Documents, which can have different structures inside the same collection, are how MongoDB stores data. As data develops, this enables increased flexibility and agility. MongoDB offers sharding, which distributes data across different servers, to enable horizontal scaling. In its "eventual consistency" concept, availability is prioritized over consistency.

标题：如何在服务器上搭建蜘蛛池？TG@yuantou2048

在互联网时代，数据的抓取和分析变得尤为重要。而“蜘蛛池”作为一项关键技术，被广泛应用于网站爬虫、数据分析等领域。本文将详细介绍如何在服务器上搭建一个高效的蜘蛛池。

1. 什么是蜘蛛池？

蜘蛛池（Spider Pool）是一种用于管理多个爬虫任务的技术方案。它通过集中管理和调度爬虫任务，提高爬虫效率，降低资源消耗。对于需要大量抓取网页信息的场景，如���索引擎优化（SEO）、市场调研等，蜘蛛池能够提供强大的支持。

2. 搭建前的准备工作

硬件准备

服务器配置：选择合适的服务器配置是基础。通常来说，CPU、内存和硬盘空间越大，处理能力越强。

操作系统：推荐使用Linux系统，因为其稳定性和安全性较高。

软件准备

Python环境：确保服务器上已安装Python及其相关库，如Scrapy、Requests等。

数据库：MySQL或MongoDB等数据库用于存储爬取的数据。

网络环境：确保服务器拥有稳定的网络环境，避免因网络波动导致的任务失败。

首先，你需要在服务器上安装必要的软件包。以Ubuntu为例：

```bash

sudo apt-get update

sudo apt-get install python3-pip

pip3 install scrapy redis

```

4. 创建项目结构

创建一个新的Scrapy项目，并配置Redis作为任务队列。

```bash

scrapy startproject myspiderpool

cd myspiderpool

```

5. 编写爬虫代码
