1.　

　　//登录数据库
　　mysql -u root -pvmwaremysql>use mysql;
　　//%为所有ip都可以远程访问
　　mysql>update user set host = '%' where user = 'root';
　　//或直接添加一条语句也行 　　
　　mysql>insert into user (host,user,password) values('192.168.1.55','root',password('123'));　　
　　//查看一下修改
　　mysql>select host, user from user;
　　//推送设置到内存或重启服务器也行
　　mysql>FLUSH PRIVILEGES

　　2.　　

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

　　如果是固定ip就这么写

　　grant all privileges on *.* to 'root'@'192.168.1.35'identified by '123' with grant option;

　　//推送设置到内存或重启服务器也行
　　mysql>FLUSH PRIVILEGES
