mysql用户想连到mysql,需要使用grant命令给用户授权,有一个简单的办法,可以使用grant ALL privileges 命令给用户授予所有权限, 你想myuser使用mypassword从任何主机连接到mysql服务器的话。

主要使用:GRANT ALL PRIVILEGES ON *.* to 'root'@'%'; 命令授权.

--grant给root使用root密码从任何主机连接到mysql服务器。

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

FLUSH PRIVILEGES;
