Failed to start mysqld.service: Unit not found

输入命令

systemctl start mysql.service

要启动MySQL数据库是却是这样的提示

Failed to start mysqld.service: Unit not found

解决方法如下:

首先需要安装mariadb-server

yum install -y mariadb-server

启动服务

systemctl start mariadb.service

添加到开机启动

systemctl enable mariadb.service

进行一些安全设置，以及修改数据库管理员密码

[zhaojq@localhost]$ mysql_secure_installation

mysql给root开启远程访问权限
use mysql；
select User,authentication_string,Host from user；

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456';
flush privileges;
