文章介绍的是在linux中的Centos 下用yum 命令部署lamp环境,供大家参考


1. Centos 默认是打开IP安全策略的,也就是80端口也禁止外部访问,所以先停用iptables.

   service iptables stop

或者对80端口开放

  iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

2. 安装

  yum install httpd (只安装apache),如果要安装其它插件可以

  yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql 

 

  安装后的网页位置是 /var/www/html

3. 安装mysql

yum install mysql mysql-server mysql-devel

 安装完成以后,运行mysql 可能出现以下错误:Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock 这个错误的原因有很多种,一种这个时候/var/lib/mysql/目录下找不到mysql.sock这个文件,可以运行 service mysqld start 或 (/etc/init.d/mysqld start) 如果成功启动mysql,那么会在/var/lib/mysql/目录下生成mysql.sock文件的,这个时候就将mysql 设置系统启动时,自动启动,否则又会重复Can't connect to local MySQL server through socket 错误。自动启动命令如下:  chkconfig mysqld on


系统默认不会设置密码的,就是空密码,如果要设置mysql 密码,假设密码设置为123456

  mysqladmin -u root pass 123456

如果要开通外部访问mysql,就要设置用户可供外部访问

  mysql> GRANT ALL PRIVILEGES ON *.* TO '用户名'@'地址' IDENTIFIED BY '密码' WITH GRANT OPTION;
  mysql> FLUSH PRIVILEGES;

  例子,允许root 用户用123456密码192.168.6.6 连接

   mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root'@'192.168.6.6' IDENTIFIED BY '123456' WITH GRANT OPTION;
   mysql> FLUSH PRIVILEGES;

   例子,允许所有外部,用户root 密码123456 连接

  mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
   mysql> FLUSH PRIVILEGES;

  例子,允许IP为192.168.6.6 ,用户root 密码123456 连接USER数据库

   mysql> GRANT ALL PRIVILEGES ON USER.* TO ‘root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
   mysql> FLUSH PRIVILEGES;

 

4. 安装php

yum install php php-mysql php-common php-gd php-mbstring php-mcrtpt php-devel php-xml
