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;
