本文介绍了如何在CentOS7系统中卸载默认的MariaDB，然后通过RPM和YUM安装MySQL5.6的过程，包括解决yum锁问题、配置启动项、设置密码和开放防火墙端口。

1.列出安装的包

# rpm -qa | grep mariadb

mariadb-libs-5.5.41-2.el7_0.x86_64

2.卸载包

# rpm -e --nodeps mariadb-libs-5.5.41-2.el7_0.x86_64

3.安装rpm包

# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

[root@localhost ~]# rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

4.查看当前可用的mysql安装资源

[root@localhost ~]# yum repolist enabled | grep "mysql.*-community.*"
Existing lock /var/run/yum.pid: another copy is running as pid 48035.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit
    Memory : 152 M RSS (557 MB VSZ)
    Started: Sat Nov 25 18:27:02 2017 - 37:44 ago
    State : Sleeping, pid: 48035

5.原因就是yum在自动更新只要关掉他就可以了

[root@localhost ~]# rm -f&nbs
