linux下安装MySQL出错！
[root@hadoop0 local]# rpm -i MySQL-server-5.5.31-2.el6.i686.rpm
file /usr/share/mysql/czech/errmsg.sys from install of MySQL-server-5.5.31-2.el6.i686 conflicts with file from package mysql-libs-5.1.66-2.el6_3.i686

原因：已存在mysql-libs-5.1.66-2.el6_3.i686的库（这是linux自带的）所以需要先删除以前的库才能安装！
执行命令：
rpm -e mysql-libs-5.1.66-2.el6_3.i686 --nodeps 强制卸载！
然后查看：
rpm -qa|grep mysql
执行安装自己的mysql:
rpm -i mysqlxxxxx.rpm
ok！搞定！
