1、打开mysql.exe(MySQL Command Line Client),输入密码
2、输入:use mysql;
3、查询host输入: select user,host from user;
4、创建host(如果有”%”这个host值,则跳过这一步)
如果没有”%”这个host值,就执行下面这两句:
mysql> update user set host=’%’ where user=’root’;
mysql> flush privileges;
5、授权用户
(1)任意主机以用户root和密码pwd连接到mysql服务器
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY ‘pwd’ WITH GRANT OPTION;
mysql> flush privileges;
(2)指定IP为(如192.168.1.100)的主机以用户tuser和密码tpwd连接到mysql服务器
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘tuser’@’192.168.1.100’ IDENTIFIED BY ‘tpwd’ WITH GRANT OPTION;
mysql> flush privileges;
