去年9月安装的服务器，php的版本已经不能满足安装Kaltura Community Edition (KalturaCE)的需要了，于是必须升级php，采用yum update php*，竟然只能升级到5.1.6，看着安装提示里的：

Required PHP version 5.2.0 and above.  You need to upgrade your PHP

就对自己的服务器窝火，KalturaCE可是好东西呀，服务器不能直接升级PHP可麻烦了。

在网上找了点资料，终于找到一种升级CentOS的php到5.3.2的方法，步骤如下：

1、wget pub/epel/5/i386/epel-release-5-3.noarch.rpm

2、wget enterprise/5/remi/i386/remi-release-5-7.el5.remi.noarch.rpm

3、rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm

4、编辑/etc/yum.repos.d/remi.repo

#vi /etc/yum.repos.d/remi.repo

在这个文件的最后增加一行：priority=1

保存退出。

5、编辑/etc/yum.repos.d/epel-testing.repo，

#vi /etc/yum.repos.d/epel-testing.repo

在这个文件的最后增加一行：priority=1

保存退出。

6、编辑/etc/yum.repos.d/epel.repo

#vi /etc/yum.repos.d/epel.repo

在这个文件的最后增加一行：priority=1

保存退出。

7、使用下面的命令进行升级（经过测试，如果单独升级php将提示失败，只有连同mysql一起升级才可以，所以我们必须执行以下命令才能升级php到5.2.9版本）：
yum –-enablerepo=remi update php* mysql*

以下为下载完成之后的执行过程，由于我本身的服务器参数和Mysql之前的升级问题，出现了以下加粗部分的警告提示，不在本文讨论范围之内：
