This indicates that Nginx was unable to find the gunicorn.sock file at the given location. You should compare the proxy_pass location defined within /etc/nginx/sites-available/myproject file to the actual location of the gunicorn.sock file generated by the gunicorn.socket systemd unit. If you cannot find a gunicorn.sock file within the /run directory, it generally means that the systemd socket file was unable to create it. Go back to the section on checking for the Gunicorn socket file to step through the troubleshooting steps for Gunicorn.
所以我做了，它说 运行 file /run/gunicorn.sock 我得到 /run/gunicorn.sock: socket，与他们的输出相同。
此外，当我 运行: sudo journalctl -u gunicorn.socket
我明白了：

我检查了我的 settings.py 文件中的 corsheader，它是：
# Application definition

'django.contrib.contenttypes',

'django.contrib.messages',

...
]
CORS_ALLOWED_ORIGINS = [
"https://example.com",
"http://example.com",
"http://localhost:8000",
"http://localhost:3000",
"http://127.0.0.1:8000",
]
那么，我的问题是什么？是吗
"Nginx was unable to find the gunicorn.sock file at the given
location"
是 corsheader 的东西吗？或者可能两者兼而有之？以及，如何解决？在进行一些更改以修复管理页面中的 css 问题之前，我确实有相同的代码，并且它没有抱怨 corseheader。感谢您阅读这么长的日志和问题。我认为您需要查看全貌才能判断可能的原因。非常感谢您的帮助，因为这让我们的网站在关键时刻无法正常运行。

我还应该注意，当我 运行 sudo nano /run/gunicorn.sock 时，文件打开时显示以下消息：
[ Error reading /run/gunicorn.sock: No such device or address ]

This Stackover flow post 帮助我进一步调试。 运行命令
gunicorn --log-file=- <app_name>.wsgi:application
我发现在我的本地机器上安装时，有几个包 (python-dotenv) 包没有安装在 Droplet 上。安装包后，我仍然收到错误消息，因为 .env 文件未在 droplet 上设置。所以，基本上我现在的问题是是否可以跟踪 .env 文件，是否应该在 droplet 上创建一个单独的 .env 文件并将我所有的环境变量放在那里，或者是否有另一种方法在 digitalocean droplet 上设置环境变量（注意 droplet 与其应用平台不同）
所以，我的问题（也可能是其他人的问题）是：
- 我没有在我的虚拟环境中安装所有的包（因此臭名昭著
502 bad gateway）
- 我的环境变量没有设置（所以，我得到
500 Server Error）。我刚刚在服务器上做了一个.env文件，把我所有的环境变量复制到那里（不建议跟踪.env文件）
- 我的迁移没有迁移到我的生产数据库。所以，我必须
python manage.py migrate
我能够通过在 settings.py 中设置 DEBUG = True 来调试问题，并查看我在哪里得到错误以及这些编程错误的真正含义（例如，如果你得到一个 AttributeError, 这意味着你还没有迁移一些迁移文件)。哦，确保你之后打开 DEBUG = False 以避免暴露该站点。我希望这可以节省 3 天的挖掘和调试工作；)
我的网站已启动并 运行ning，但管理员 CSS 未加载，我不确定服务器不同意我做了什么，但现在整个网站都是关闭 502 Bad Gateway 消息。

This indicates that Nginx was unable to find the gunicorn.sock file at the given location. You should compare the proxy_pass location defined within /etc/nginx/sites-available/myproject file to the actual location of the gunicorn.sock file generated by the gunicorn.socket systemd unit. If you cannot find a gunicorn.sock file within the /run directory, it generally means that the systemd socket file was unable to create it. Go back to the section on checking for the Gunicorn socket file to step through the troubleshooting steps for Gunicorn.
所以我做了，它说 运行 file /run/gunicorn.sock 我得到 /run/gunicorn.sock: socket，与他们的输出相同。
此外，当我 运行: sudo journalctl -u gunicorn.socket
我明白了：

我检查了我的 settings.py 文件中的 corsheader，它是：
# Application definition
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
# 3rd party apps:
'corsheaders',
...
]
MIDDLEWARE = [
# 3rd party middleware
'debug_toolbar.middleware.DebugToolbarMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
...
]
CORS_ALLOWED_ORIGINS = [
"https://example.com",
"http://example.com",
"http://localhost:8000",
"http://localhost:3000",
"http://127.0.0.1:8000",
]
那么，我的问题是什么？是吗
"Nginx was unable to find the gunicorn.sock file at the given location"
是 corsheader 的东西吗？或者可能两者兼而有之？以及，如何解决？在进行一些更改以修复管理页面中的 css 问题之前，我确实有相同的代码，并且它没有抱怨 corseheader。感谢您阅读这么长的日志和问题。我认为您需要查看全貌才能判断可能的原因。非常感谢您的帮助，因为这让我们的网站在关键时刻无法正常运行。

我还应该注意，当我 运行 sudo nano /run/gunicorn.sock 时，文件打开时显示以下消息：
[ Error reading /run/gunicorn.sock: No such device or address ]

This Stackover flow post 帮助我进一步调试。 运行命令
gunicorn --log-file=- <app_name>.wsgi:application
我发现在我的本地机器上安装时，有几个包 (python-dotenv) 包没有安装在 Droplet 上。安装包后，我仍然收到错误消息，因为 .env 文件未在 droplet 上设置。所以，基本上我现在的问题是是否可以跟踪 .env 文件，是否应该在 droplet 上创建一个单独的 .env 文件并将我所有的环境变量放在那里，或者是否有另一种方法在 digitalocean droplet 上设置环境变量（注意 droplet 与其应用平台不同）
所以，我的问题（也可能是其他人的问题）是：
- 我没有在我的虚拟环境中安装所有的包（因此臭名昭著
502 bad gateway） - 我的环境变量没有设置（所以，我得到
500 Server Error）。我刚刚在服务器上做了一个.env文件，把我所有的环境变量复制到那里（不建议跟踪.env文件） - 我的迁移没有迁移到我的生产数据库。所以，我必须
python manage.py migrate
我能够通过在 settings.py 中设置 DEBUG = True 来调试问题，并查看我在哪里得到错误以及这些编程错误的真正含义（例如，如果你得到一个 AttributeError, 这意味着你还没有迁移一些迁移文件)。哦，确保你之后打开 DEBUG = False 以避免暴露该站点。我希望这可以节省 3 天的挖掘和调试工作；)
