Python管理.py运行服务器_mysql_exceptions.OperationalError：（2002，“无法通过套接字'/ tmp / mysql.sock'（2）连接到本地MySQL服务器”）

Question

我想运行"python manage.py runserver"，已经安装了mysql、django和它们一起使用的适当工具：Mysql-django。但是尝试运行时出现了以下错误：

$ python manage.py runserver
Validating models...

Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x110251450>>

_mysql_exceptions.OperationalError: **(2002, "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)")**

这是我的settings.py文件的内容。

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

你的MySQL服务器正在运行吗？ - Blender

你的MySQL服务器是否配置为监听/tmp/mysql.sock？ - sarnold

@Sarnold 不，我该如何配置它？ - user1467736

当settings.py数据库HOST配置为''或'localhost'时，杀死mysql进程然后尝试启动开发服务器会产生一个错误，就像它在寻找“/tmp/mysql.sock”一样。这意味着sarnold所建议的，你的mysql正在特定的unix套接字上运行。 - jdi

问题在于我使用的是Python3，而Django目前不兼容。 - user1467736

Answer 1

我也遇到了这个问题。你只需要将数据库主机从localhost更改为127.0.0.1就可以解决此问题。

我浪费了整整2个小时试图找到问题。谢天谢地我看到了这个！ - nishant_boro

Answer 2

为了找到你的mysql套接字以进行配置，请输入以下命令。

mysql_config --socket

获取结果并应用它：

'HOST': '/Applications/MAMP/tmp/mysql/mysql.sock',

尽管我正在使用MAMP，但这应该适用于其他情况。
