无法连接到MySQL服务器错误111 [英] Can't connect to MySQL server error 111

问题描述

我在linux机器IP = 192.168.1.100上安装了mysql服务器，但是当我尝试连接到该IP时，它总是报错(111).但使用localhost并可以使用127.0.0.1.

I installed mysql server on linux box IP = 192.168.1.100 but when i try to connect to this IP it alway error(111). but use localhost and 127.0.0.1 is OK.

beer@beer-laptop# ifconfig | grep "inet addr"
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0

beer@beer-laptop# mysql -ubeer -pbeer -h192.168.1.100
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.100' (111)

从另一台计算机连接它也会出现错误111.

Connect from another machine it also error 111.

another@another-laptop# mysql -ubeer -pbeer -h192.168.1.100
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.100' (111)

在这种情况下，使用localhost/127.0.0.1和192.168.1.100有何区别. 我不知道如何从另一台计算机连接到该数据库.

How difference between use localhost/127.0.0.1 and 192.168.1.100 in this case. I don't know how to connect to this database from another machine.

请帮助. 谢谢.

推荐答案

这可能意味着您的MySQL服务器仅在监听localhost接口.

It probably means that your MySQL server is only listening the localhost interface.

如果您有这样的行:

bind-address = 127.0.0.1

在您的 my.cnf配置文件中，应为它们添加注释(在#的开头添加#行)，然后重新启动MySQL.

In your my.cnf configuration file, you should comment them (add a # at the beginning of the lines), and restart MySQL.

sudo service mysql restart

当然，要做到这一点，您必须是服务器的管理员.

Of course, to do this, you must be the administrator of the server.
