mysql開啓遠程訪問權限

　1.　
  //登陸數據庫
　　mysql -u root -pvmwaremysql>use mysql; 
　　//%爲全部ip均可以遠程訪問
　　mysql>update user set host = '%' where user = 'root';  
   //或直接添加一條語句也行   　　
   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;    
   //推送設置到內存或重啓服務器也行
　　mysql>FLUSH PRIVILEGES 
 
  2.　　
 GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 
  若是是固定ip就這麼寫
 grant all privileges on *.* to 'root'@'192.168.0.49'identified by '123' with grant option;

//推送設置到內存或重啓服務器也行　　mysql>FLUSH PRIVILEGES
