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>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 Cstate NEW -m tcp -p tcp Cdport 21 -j ACCEPT iptables -I RH-Firewall-1-INPUT -m state Cstate NEW -m tcp -p tcp Cdport 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。
