梳理了一下centos上安装mysql的三种方法：一是通过源码安装，二是用通用二进制包，三是通过不同linux release到系统包安装,centos上是RPM包安装。
先来rpm包装

环境
[root@host2 ~]# uname -a

检查是否安装
[root@host2 ~]# rpm -qa | grep -i mysql
文件名
MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle.tar
3
删除已安装
[root@host2 ~]# rpm -e mysql-libs-5.1.71-1.el6.x86_64 --nodeps
[root@host2 ~]#

查验，这样删还是会留下一些东西
[root@host2 ~]# find / -name mysql
[root@host2 ~]# find / -name *mysql*

[root@host2 ~]# rpm -qa | grep -i mysql
[root@host2 ~]#

查验有否mysql用户和组
[root@host2 ~]# nl /etc/group | grep mysql
[root@host2 ~]# nl /etc/shadow | grep mysql
[root@host2 ~]#

解包
[root@host2 mysql_rpm]# tar -xvf MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle.tar
