1、安装依赖

[root@node001 ~]# yum install -y perl
Loaded plugins: fastestmirror
Loading mirror speeds from cached
hostfile
base | 3.7 kB 00:00
extras | 3.4 kB 00:00
updates | 3.4 kB 00:00
Setting up Install Process
Package 4:perl-5.10.1-144.el6.x86_64
already installed and latest version
Nothing to do

2、 卸载旧本子的mysql及插件

[root@node001 ~]# rpm -qa | grep mysql
mysql-5.1.73-8.el6_8.x86_64
mysql-libs-5.1.73-8.el6_8.x86_64
mysql-server-5.1.73-8.el6_8.x86_64

[root@node001 ~]# rpm -e mysql-5.1.73-8.el6_8.x86_64
–nodeps

[root@node001 ~]# rpm -e
mysql-libs-5.1.73-8.el6_8.x86_64 –nodeps

[root@node001 ~]# rpm -e
mysql-server-5.1.73-8.el6_8.x86_64 –nodeps

(–nodeps:忽略任何因,直接卸载)

3、 安装rpm(4个)

安装包
