CentOS 5 升級PHP 5.3的方法

C5-testing這個repo的php版本更新好慢，想試試較新版本的php得換別隻repo了。

for i386：
wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm
yum --enablerepo=remi update php php-*

for x86_64：
wget http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm
yum --enablerepo=remi update php php-*

如果在x64的環境下更新PHP跟MySQL的時候，遇到如下的錯誤訊息：

file /etc/my.cnf from install of mysql-libs-5.5.21-1.el5.remi.x86_64 conflicts with file from package mysql-5.0.77-3.el5.i386

那是因為i386版的mysql也被裝到系統裡面了，所以影響了yum的更新，解決方法如下：
yum remove mysql-5.0.77-3.el5.i386

看你錯誤訊息的package name是啥，就跟著輸入，讓yum把i386版的移除後，就沒問題了。
