用root身份登录mysql服务器:mysql -h localhost -u root

赋予任何主机使用 username 远程访问:mysql>GRANT ALL PRIVILEGES ON *.* TO 'username'@'%'WITH GRANT OPTION

设置指定的用户只能从指定的ip进行访问,这里是新建了远程访问的用户:

GRANT ALL PRIVILEGES ON *.* TO 'user'@'192.168.1.250' IDENTIFIED BY 'password' WITH GRANT OPTION;//phpfensi.com

指定已有用户只能从指定ip访问:GRANT ALL PRIVILEGES ON *.* TO 'user'@'192.168.1.250' WITH GRANT OPTION;

刷新生效:FLUSH PRIVILEGES
