需要打开用户权限和mysql的本机绑定

1、在命令行底下打开用户权限:grant all privileges on drupal.* to user@192.168.1.80 identified by 'user-password';

在管理员界面可以通过用户管理add host->any host来添加访问权限（root用户默认只能访问本机，新添加的用户可远程）

2、取消mysql本机绑定：

编辑/etc/mysql/my.cnf

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 127.0.0.1

将”bind-address = 127.0.0.1“注释

sudo /etc/init.d/./mysql restart重启即可远程访问。
