mysql开启远程访问权限

　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('192.168.0.51','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'@'192.168.0.49'identified by '123' with grant option;

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