mysql 访问权限设置

mysql 默认只能 本机访问：

　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
