如何连接到另一台主机上的MySQL服务器？ [英] How to connect to MySQL server on another host?

问题描述

通过在中设置 HOST 和 PORT ，Django可以简单地连接到自己的MySQL服务器。 settings.py as''（空字符串）：

Django can simply connect to its own MySQL server by setting HOST and PORT in settings.py as '' (empty string):

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'dbname',                   # Or path to database file if using sqlite3.
        'USER': 'root',                      # Not used with sqlite3.
        'PASSWORD': 'root',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

我的问题是如何能够连接另一个数据库在另一台主机上？假设我的机器是 192.168.1.33 ，另一台要连接的机器是 192.168.1.34 ，它们都在同一个网络。我尝试设置为：

My question is how to make it able to connect another database on another host? Suppose my machine is 192.168.1.33 and another machine to be connected is 192.168.1.34, both are on the same network. I've tried to set this as:

'HOST': '192.168.1.34',
'PORT': '3306',

和

'HOST': '192.168.1.34',
'PORT': '',

但都导致此 OperationalError ：

(2003, "Can't connect to MySQL server on '192.168.1.34'(10061)")

1. 配置绑定地址到您想要的主机 etc / mysql / my.cnf

为要授予访问权的主机创建一个新用户

Create a new user for the host you want to give an access (if you don't have one).

检查该用户的权限（如果访问被拒绝）

推荐答案

默认情况下，基于Debian的发行版配置MySQL绑定到localhost，这意味着其他主机无法连接到它。修复您的MySQL配置，并且它将工作。

By default, Debian-based distros configure MySQL to bind to localhost only, which means that other hosts cannot connect to it. Fix your MySQL configuration and it will work.

编辑 /etc/mysql/my.cnf ：

bind-address = 127.0.0.1

到此：

bind-address = 0.0.0.0

这会将MySQL暴露给所有网络接口，因此，如果此服务器暴露给不受信任的

This will expose MySQL to all network interfaces, so make sure that you have security measures in place if this server is exposed to untrusted hosts.
