1、下载和安装yum 源：wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -ivh epel-release-6-8.noarch.rpm wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm rpm -ivh remi-release-6.rpm 2、开启源：vi /etc/yum.repos.d/remi.repo 更改［remi］下的enabled＝0为1 3、首先需要卸载所有php5.3的程序，然后重新yum安装php就可以了 4、如果报错：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again 解决办法： vi /etc/yum.repos.d/epel.repo 编辑[epel]下的baseurl前的#号去掉，mirrorlist前添加#号
