Manually install and compile LAMP

Manually install and compile LAMP

Preface

This time I mainly introduce the LAMP architecture and the whole process of manual installation and configuration. The process is written in detail as much as possible. The relevant software packages are prepared in advance, and the corresponding folders are created.

1. Apache website service

1.1 Origin of Apache

  • Originated from A Patchy Server, the famous open source web service software
  • In 1995, the 1.0 version of the Apache service program was released
  • Maintained by the Apache Software Foundation (ASF)
  • The latest name is "Apache HTTP Server"
  • Official site: htp://httpd.apache.org/

1.2 Main features

  • Open source code, cross-platform application
  • Support multiple web programming languages
  • Modular design, stable operation, good safety

1.3 Software version

1.X

  • The current highest version is 1.3, stable operation
  • Good backward compatibility, but lacks some newer features

2.X

  • The current highest version is 2.4
  • Has more features
  • Compared with 1.X, there is a big difference in configuration management style

1.4 Advantages of Compiling and Installing Apache Service

  • With greater freedom, functions can be customized
  • Get the latest software version in time
  • Universally applicable to most Linux versions, easy to transplant

Obtain the source code package of the Apache server

  • Reference address: htp://ttpd.apache.org/download.cgi

1.5 Directory structure of httpd service

Main directories and files

  • Service directory: /usr/local/httpd/
  • Main configuration file: /usr/local/httpd/conf/httpd.conf
  • Web directory: /usr/local/httpd/htdocs/
  • Service script: /usr/local/httpd/bin/apachectl
  • Executing program: /usr/local/httpd/bin/httpd
  • Access log: /usr/local/httpd/log/access_log
  • Error log: /usr/local/httpd/log/error_log

1.6 httpd.conf configuration file

Commonly used global configuration parameters

  • ServerRoot: Service Directory
  • Listen: listening IP address and port number
  • User: The identity of the user running the service
  • Group: The identity of the group running the service
  • ServerAdmin: Administrator mailbox
  • ServerName: The domain name of the website server
  • DocumentRoot: The root directory of the web document
  • DirectoryIndex: The default index page file
  • ErrorLog: Set the path of the error log file
  • LogLevel: The level of logging, the default is warn

Commonly used global configuration parameters (continued)

  • CustomLog: The location of the access log file
  • PidFile: The file that saves the PID number of the httpd process
  • AddDefaultCharset: Set the default character set encoding of web pages in the site
  • Timeout: network connection timeout, the default is 300 seconds
  • KeepAlive: Whether to keep the connection, optional On or Off
  • MaxKeepAliveRequests: Maximum number of requested files per connection
  • KeepAliveTimeout: The timeout period when keeping the connected state
  • Include: other configuration files that need to be included

Two, MySQL compilation and installation

2.1 Introduction to MySQL

  • MySQL is an open source relational database management system (RDBMS) that uses the most commonly used database management language-Structured Query Language (SQL) for database management.
  • MySQL is open source, so anyone can download it under the General Public License and modify it according to individual needs.
  • MySQL is a true multi-threaded, multi-user SQL database service, which has attracted much attention for its speed, reliability and adaptability. Most people think that MySQL is the best choice for managing content when transactional processing is not required.

3.1 Introduction to PHP

  • PHP stands for "Hypertext Preprocessor" and is a universal open source scripting language. PHP is a scripting language executed on the server side, similar to the C language, and is a commonly used website programming language. PHP's unique syntax is a mixture of C, Java, Perl, and PHP's own syntax. Conducive to learning, widely used, mainly suitable for the field of Web development
  • PHP supports most of the popular databases, the operation function at the database level is very powerful, and it can support Unix, Windows, Linux and other operating systems
