Linux系统CentOS使用yum方式安装指定版本的PHP 添加yum源 从PHP5.3升级到5.4/5.5/5.6

默认的版本过低了，手动安装有一些麻烦，想采用Yum安装的能够使用下面的方案：
首先删除旧版本的PHP，
经过yum list installed | grep php能够查看全部已安装的php软件
使用yum remove php ……删除

经过yum list php*查看是否有本身须要安装的版本，若是没有就须要添加第三方yum源， 推荐安装webtatic、rpmforge，还有国内163的

CentOs 5.x 
rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm 
CentOs 6.x 
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm 
CentOs 7.X 
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm 
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
//rpmforge
#32位：  
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm  
rpm -ivh rpmforge-release-0.5.1-1.el5.rf.i386.rpm  
#64位：  
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm  
rpm -ivh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm  

安装完成后能够使用yum repolist查看已经安装的源，也能够经过ls /etc/yum.repos.d/查看。 

而后再yum install php55w或yum install php54w或yum install php56w||yum install php70w……就能够安装新版本PHP了
