1. 换源,sohu的相当好用。

1.1备份CentOS-Base.repo

cd /etc/yum.repos.d/

cp CentOS-Base.repo CentOS-Base.repo.bak

1.2替换源

用vi打开CentOS-Base.repo,并将内容清空,然后将下面的内容复制进去,并保存。

# CentOS-Base.repo

#

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client. You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

#

1.3更新一下。

yum -y update

2. 用yum安装Apache,Mysql,PHP.

2.1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

2.2 安装mysql

2.2.1 yum install mysql mysql-server mysql-devel

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

2.2.2 设置mysql密码

mysql>; USE mysql;

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

mysql>; FLUSH PRIVILEGES;

2.2.3 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。

2.2.4 设为开机启动

chkconfig mysqld on

3. 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

4. 测试一下

4.1在/var/www/html/新建个test.php文件,将以下内容写入,然后保存。

<?

phpinfo();

?>

4.2 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

4.3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。
