Mac 上的 Django + XAMPP（2002，“无法通过套接字'/tmp/mysql.sock'（2）连接到本地 MySQL 服务器”）

Question

I am following this tutorial to build a Django app with MySQL.

I am using XAMPP-VM for Mac. I set up my Database settings for Django as so:

 DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'djangoproject', 'USER': 'root', 'PASSWORD': '', 'HOST': 'localhost', 'PORT': '8080', } }

And I have started MySQL on XAMPP but when I run python manage.py migrate I get:

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

Thank you for your help!

Answer 1

Just change HOST from localhost to the ip 127.0.0.1 . This will resolve your problem.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'djangoproject',
        'USER': 'root',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '8080',
    }
}

Answer 2

The mysql client tries to connect through the /tmp/mysql.sock by default. You just have to point it to XAMPP's socket with a symbolic link.

ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock

Answer 3

I would try changing your HOST from 'localhost' to '127.0.0.1'. This usually rectifies it on my end.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'djangoproject',
        'USER': 'root',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '8080',
    }
}

Answer 4

我在 mysql 最新版本中遇到了同样的错误，所以我降级到 mysql 5.7.0 并且它工作正常。

Answer 5

This is probably due to XAMPP-VM being installed and not the local XAMPP. Uninstall XAMPP-VM and install XAMPP.
