Setting up Install Process

Package 4:perl-5.10.1-144.el6.x86_64 already installed and latest version

Nothing to do

2、 卸载旧版本的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:忽略其他依赖，直接卸载)

3、 安装rpm(4个)
