今天用yum方法搭建起了个LAMP环境,中间遇到了很多问题,经过google和各位前辈的帮助,终于将环境搭建起来,现在把完整的步骤记录下来,

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. 
# 
# 
[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
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&gt;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
在/var/www/html/新建个test.php文件,将以下内容写入,然后保存。
<?
phpinfo();
?>
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。
