1、1。 改表法。可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 "mysql"数据库里的 "user" 表里的 "host" 项，从"localhost"改成"%"Sql代码 1.mysql-u root -pvmwaremysql>use mysql; 2. mysql>update user set host = '%' where user = 'root'; 3. mysql>select host, user from user;
2、2. 授权法。例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。Sql代码 1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 2.FLUSH PRIVILEGES;如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码Sql代码 1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 2. 'mypassword' WITH GRANT OPTION; 3. FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY'mypassword' WITH GRANT OPTION;FLUSH PRIVILEGES;如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码Sql代码 1. GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 2. 'mypassword' WITH GRANT OPTION; 3. FLUSH PRIVILEGES; GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY'mypassword' WITH GRANT OPTION;FLUSH PRIVILEGES;注意授权后必须FLUSH PRIVILEGES;否则无法立即生效。
3、另外一种方法.在安装mysql的机器上运行：1、d:\mysql\bin\>mysql -h localhost -u root//这样应该可以进入MySQL服务器2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION//赋予任何主机访问数据的权限3、mysql>FLUSH PRIVILEGES//修改生效4、mysql>EXIT//退出MySQL服务器这样就可以在其它任何的主机上以root身份登录啦！其它：mysql> grant all privileges on *.* to 'energy_pf'@'192.168.2.65' identified by 'energy_pf' with grant option;Query OK, 0 rows affected (0.00 sec)mysql> plush privileges;允许用户energy_pf从ip为192.168.2.65的主机连接到mysql服务器的任意数据库（*.*），并使用energy_pf作为密码
