centos下yum快速安装lamp环境

用yum安装Apache,Mysql,PHP.

1.1安装Apache

        yum install httpd httpd-devel

        安装完成后，用/etc/init.d/httpd start 启动apache

        设为开机启动:chkconfig httpd on

1.2 安装mysql

      1.2.1 yum install mysql mysql-server mysql-devel

                同样，完成后，用/etc/init.d/mysqld start 启动mysql 

      1.2.2 设置mysql密码

                mysql>; USE mysql;

                mysql>; UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';

                mysql>; FLUSH PRIVILEGES; 

      1.2.3 允许远程登录

                mysql -u root -p

                Enter Password: <your new password>

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

                完成后就能用mysql-front远程管理mysql了。 

       1.2.4 设为开机启动

               chkconfig mysqld on
2. 安装php

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

        /etc/init.d/httpd start
3. 测试一下

       3.1在/var/www/html/新建个test.php文件，将以下内容写入，然后保存。

       <?

           phpinfo();

       ?>

       3.2 防火墙配置

             a.添加.允许访问端口{21: ftp, 80: http}.

                iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT

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

             b.关闭防火墙{不推荐}.

                service iptables stop

             c.重置加载防火墙

                service iptables restart

      3.3然后在客户端浏览器里打开http://serverip/test.php，若能成功显示，则表示安装成功。

至此，安装完毕。感慨，yum真是太好用了。
