mysql允许root本地登录_mysql 允许root从远程登录

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”改称“%”

mysql -u root -pvmwaremysql>use mysql;

mysql>update user set host = ‘%’ where user = ‘root’;

mysql>select host, user from user;

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。

GRANT ALL PRIVILEGES ON *.* TO ‘myuser’@'%’ IDENTIFIED BY ‘mypassword’ WI

TH GRANT OPTION;

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

GRANT ALL PRIVILEGES ON *.* TO ‘myuser’@'192.168.1.3′ IDENTIFIED BY

‘mypassword’ WITH GRANT OPTION;

我用的第一个方法,刚开始发现不行,在网上查了一下,少执行一个语句 mysql>FLUSH PRIVILEGES

使修改生效.就可以了

x:>mysql -u root -pvmware

mysql> use mysql;

mysql> update user set host = ‘%’ where user = ‘root’;

mysql> select host, user from user;

mysql> flush privileges;
