mysql升级后php无法使用

mysql用jason的源后，虽然可以直接yum到5.5了，但是php-mysql无法使用了

总是无法update到对应的依赖包。

错误如下：

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

谷歌了好久，得到的方案是，把php和mysql相关的都删除了，然后切换一个源，重新安装php和mysql

删除php内容

rpm-qa|grepmysql

rpm-qa|grepphp

把看到的内容都删除了

yumremovephp-*

yumremovemysql

yumerasemysql-libs

切换源

rpm-Uvhhttp://rpms.famillecollet.com/enterprise/remi-release-5.rpm

安装mysql

yum--enablerepo=remi,remi-testinstallmysqlmysql-server

yum--enablerepo=remi,remi-testinstallphp

yum--enablerepo=remi,remi-testinstallphp-mysql

终于再也没看到那个可恶的包依赖了。
