使用yum 命令先卸载掉mariadb

[root@node04 ~]# yum -y remove mariadb-libs.x86_64

[root@node04 ~]# yum install mysql-server

[root@node04 ~]# service mysqld start

授权

[root@node04 ~]# mysql

mysql -uroot

mysql> use mysql

mysql> show tables;

mysql> select user,host,password from user;

mysql> delete from user;

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

mysql> flush privileges;

mysql> exit

[root@node04 ~]# mysql -uroot -proot
