CentOS使用yum来安装LAMP

dinggela

　　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。
