1. installation environment: RedHat AS 4

2. install Apache, MySQL, and PHP

(1) install MySQL

: Http://dev.mysql.com/downloads/mysql/5.0.html

// Check whether MySQL is installed in the system. If yes, Uninstall all packages starting with mysql.

# Rpm-qa | grep mysql

# Rpm-e mysql -*

// Find/etc/my. cnf (MySQL option configuration file). If yes, delete it to avoid affecting the startup of the new installation version.

# Rm-f/etc/my. cnf

# Tar-zxvf mysql-standard-5.0.27-linux-i686-glibc23.tar.gz

# Cp-rf mysql-standard-5.0.27-linux-i686-glibc23/usr/local/

// Create a symbolic link. If a new version of MySQL is available in the future, you can just extract the source code to a new path and re-create a symbolic link. This is very convenient and data is more secure.

# Ln-s mysql-standard-5.0.27-linux-i686-glibc23/usr/local/mysql

// Add the user and user group used to start MySQL (if MySQl has been installed before, the user and user group may already exist ).

# Useradd mysql

# Groupadd mysql

// Initialize the authorization table

# Cd/usr/local/mysql

# Scripts/mysql_install_db

// Modify the ownership of the MySQl directory

# Cd/usr/local

# Chgrp-R mysql mysql-standard-5.0.27-linux-i686-glibc23.

# Chgrp-R mysql

# Chown-R mysql mysql-standard-5.0.27-linux-i686-glibc23/data

# Chown-R mysql/data

# Ln-s/usr/local/mysql/bin/*/usr/local/bin/

Set-variable = max_connections = 1000

Set-variable = max_user_connections = 500

Set-variable = wait_timeout = 200

// Set max_connections to 1000

// Set max_user_connections to 500

// Wait_timeout indicates that the IDLE (IDLE) connection will be closed after 200 seconds, but it will not affect the working connection.

// Save and exit, and restart MySQL

// Restart MySQL and run the following command to check whether the modification is successful.

# Mysqladmin-uroot-p variables
