启动停止MySql服务

MySql初始化

mysqld --user=mysql --basedir=/home/mysql/mysql8 --datadir=/home/mysql/mysql8/data --initialize

MySql创建用户并赋权

MySQL8创建用户与授权时分开的,如果使用MySQL5的授权方式会出现以下错误：

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'zhaoty' WITH GRANT OPTION' at line 1

#创建账户(% 代表所有IP)
create user 'root'@'%' identified by  'password'

#赋予权限，with grant option这个选项表示该用户可以将自己拥有的权限授权给别人
grant all privileges on *.* to 'root'@'%' with grant option

MySql修改用户密码

#修改用户密码
alter user 'root'@'localhost' identified with mysql_native_password by 'zhaoty';

#刷新权限
flush privileges;
