5.5使用yum来安装LAMP-CentOS-php运行环境

1. 换源，sohu的相当好用。 1.1备份CentOS-Base.repocd /etc/yum.repos.d/cp CentOS-Base.repo CentOS-Base.repo.bak1.2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-$releasever - Basebaseurl=$releasever/os/$basearch/gpgcheck=1gpgkey=updates[updates]name=CentOS-$releasever - Updatesbaseurl=$releasever/updates/$basearch/gpgcheck=1gpgkey=used/produced in the build but not released[addons]name=CentOS-$releasever - Addonsbaseurl=$releasever/addons/$basearch/gpgcheck=1gpgkey=packages that may be useful[extras]name=CentOS-$releasever - Extrasbaseurl=$releasever/extras/$basearch/gpgcheck=1gpgkey=packages that extend functionality of existing packages[centosplus]name=CentOS-$releasever - Plusbaseurl=$releasever/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=更新一下。yum -y update 2. 用yum安装Apache,MYSQL,PHP. 2.1安装Apacheyum 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 on2.2 安装mysql2.2.1 yum install mysql mysql-server mysql-devel同样，完成后，用/etc/init.d/mysqld start 启动mysql2.2.2 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 -pEnter 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。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 ACCEPTiptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPTb.关闭防火墙{不推荐}.service iptables stopc.重置加载防火墙service iptables restart4.3然后在客户端浏览器里打开，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。
