.rpm -qa | grep mysql
qt-mysql-4.8.5-11.el7.x86_64
pcp-pmda-mysql-3.10.6-2.el7.x86_64
akonadi-mysql-1.9.2-4.el7.x86_64
2.卸载上面三个包
rpm -e akonadi-mysql
rpm -e qt-mysql
rpm -e pcp-pmda-mysql
强制卸载,添加--nodeps
例如: rpm -e --nodeps akonadi-mysql
3 rpm -qa | grep mariadb
#列出所有被安装的rpm package
4.删除所有第三步列出的包
5.CentOS 7的yum源中貌似没有正常安装mysql时的mysql-sever文件,需要去官网上下载
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server
成功安装之后重启mysql服务
# service mysqld restart
初次安装mysql是root账户是没有密码的
设置密码的方法
# mysql -uroot
mysql> set password for ‘root’@‘localhost’ = password('root');
mysql> exit
