1：也许之前的机器安装过Mysql，但是自己不知道，账号密码也忘记了，又执行安装操作，导致Mysql不兼容问题。Linux上安装MySQL时出现不兼容的解决办法，错误如下所示：
[root@master package]# rpm -ivh MySQL-server-5.1.-.glibc23.i386.rpm

2：出现问题了，就解决呗，原因是系统已经安装了其他版本的mysql-libs包导致不兼容。
可以使用命令查看yum list | grep mysql，查看之前安装的mysql的信息，如下所示：
[root@master package]# yum list | grep mysql

3：将之前的mysql的lib包删除了即可，删除mysql-libs：
[root@master package]# yum remove mysql-libs

4：然后开始安装你的mysql，在linux操作系统上面：http://www.cnblogs.com/biehongli/p/7693598.html
5：以上方法，亲测可以，下面是更暴力卸载的，看着好像方便些，未测：https://www.cnblogs.com/angelasp/p/4301446.html
停更......
