CentOS 5.5使用yum安装LAMP环境（sohu源）

CentOS 5.5默认的是163的源，据说sohu的源很好用，今天小试了下。

 1、修改yum配置文件，更改为sohu源

# cd /etc/yum.repos.d/ 
# cp CentOS-Base.repo CentOS-Base.repo.bak

• 清空CentOS-Base.repo文件内容，替换为以下内容：

# 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. 
# 
# 
[base] 
name=CentOS-$releasever - Base 
baseurl=http://mirrors.sohu.com/centos/$releasever/os/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#released updates 
[updates] 
name=CentOS-$releasever - Updates 
baseurl=http://mirrors.sohu.com/centos/$releasever/updates/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#packages used/produced in the build but not released 
[addons] 
name=CentOS-$releasever - Addons 
baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#additional packages that may be useful 
[extras] 
name=CentOS-$releasever - Extras 
baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/ 
gpgcheck=1 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5 
#additional packages that extend functionality of existing packages 
[centosplus] 
name=CentOS-$releasever - Plus 
baseurl=http://mirrors.sohu.com/centos/$releasever/centosplus/$basearch/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

• 更新源

# yum -y update

2、使用yum命令安装apache、mysql、PHP环境

#yum -y install httpd php mysql mysql-server php-mysql
#这里只装了最基础的，其他扩展没装

3、设定服务启动与自启动

# chkconfig httpd on
# chkconfig --add mysqld
# chkconfig mysqld on

# service httpd start
# service mysqld start 

4、防火墙设置

a.添加.允许访问端口{21: ftp, 80: http}. 
# iptables -I INPUT -p tcp --dport 80 -j ACCEPT
# 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.或者关闭防火墙(不推荐). 
# service iptables stop 
c.重置加载防火墙 
# service iptables restart

5、修改mysql的密码

#mysqladmin -u root password 'root'

其他的配置，童鞋们自己搞吧
