Linux 卸载mysql-libs包出现错误

在Red Hat Enterprise Linux6.6上安装MySQL时，出现与package mysql-libs-5.1.73-3.el6_5.x86_64冲突的情况

[root@localhost tmp]# rpm -ivh MySQL-server-advanced-5.6.20-1.rhel5.x86_64.rpm

在安装之前检查发现已经有了mysql-libs包，但是并没有卸载该包，既然冲突了，就必须要卸载mysql-libs-5.1.73-3.el6_5.x86_64包，卸载过程中出现error: Failed dependencies，依赖性的问题。 使用参数--nodeps删除了该组件

[root@localhost tmp]# rpm -qa | grep -i mysql
mysql-libs-5.1.73-3.el6_5.x86_64

[root@localhost tmp]# rpm -ev mysql-libs-5.1.73-3.el6_5.x86_64
