再给新项目使用rpm安装MySQL的时候，报错：
[root@zhanglin ~]# rpm -ivh MySQL-server-5.6.19-1.el6.x86_64.rpm

1、查看是否安装了MySQL
[root@zhanglin ~]# rpm -aq|grep mysql
mysql-libs-5.1.61-4.el6.x86_64
2、删除系统自带的。
mysql-libs-5.1.61-4.el6.x86_64的库（这是linux自带的,在装系统的时候被勾选了）所以需要先删除以前的库才能安装！
执行命令：
[root@zhanglin ~]# rpm -e mysql-libs-5.1.61-4.el6.x86_64 ------可能删不掉，因为有些依赖的包
[root@zhanglin ~]# rpm -e mysql-libs-5.1.61-4.el6.x86_64 --nodeps ------强制卸载！
3、再次检查是否删除掉，若删掉就可以rpm安装了。
