使用yum在CentOS上将PHP升级到5.2.12

我试图找到一种简单的方法来升级我的CentOS5机器上的PHP yum而不是下载源代码并自己再次编译它(我上次做了,但是很难让所有的编译配置与CentOS的默认配置相同).无论如何,我最终使用这里列出的方法:http: //www.atomicorp.com/wiki/index.php/PHP

现在,该命令php -v显示版本已经是5.2.11(我需要),但它总是包含许多警告,如:

PHP Warning:  PHP Startup: fileinfo: Unable to initialize   module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP    compiled with module API=20060613, debug=0, thread-safety=0
These options need to match
in Unknown on line 0

PHP Warning:  PHP Startup: mcrypt: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP    compiled with module API=20060613, debug=0, thread-safety=0
These options need to match
in Unknown on line 0

PHP Warning:  PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP    compiled with module API=20060613, debug=0, thread-safety=0

PHP Warning:  PHP Startup: mssql: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP    compiled with module API=20060613, debug=0, thread-safety=0
These options need to match

我认为这基本上意味着我需要重新编译这四个模块,我怎么能这样做？任何建议表示赞赏.
