在Digital ocean上部署Django、Gunicorn、Nginx和Virtualenv会给我带来502坏网关&；古尼康罐头盒'；不读取密钥

我已经尝试部署了2天了，尽管我阅读了很多文章、StackOverflow问题和数字海洋教程，但似乎无法让它正常工作

我的主要教程是：

当我绑定gunicorn文件（见下面的命令）并转到我的ip地址8001时，一切正常

gunicorn --bind 0.0.0.0:8001 vp.wsgi:application 

但是在我创建和编辑我的gunicorn.service文件的地方：

sudo nano /etc/systemd/system/gunicorn.service 

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=tony
Group=www-data
WorkingDirectory=/home/tony/vp/vp/
ExecStart=/home/tony/vp/vpenv/bin/gunicorn --workers 3 --bind unix:/home/tony/vp/vp/vp.sock vp.wsgi:application

[Install]
WantedBy=multi-user.target

2017/04/23 13:41:19 [crit] 15491#15491: *2 connect() to unix:/home/tony/vp/vp/vp.sock failed (2: No such file or directory) while connecting to upstream, client: Client.IP, server: Server.IP, request: "GET / HTTP/1.1", upstream: "http://unix:/home/tony/vp/vp/vp.sock:/", host: "Server.IP"

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")

application = get_wsgi_application()

和我的nginx文件（为了隐私，我用我的ip地址替换了我的ip地址）

我收到一个错误的网关502

即使在重新加载所有内容之后：

(vpenv) ~/vp/vp$ sudo systemctl daemon-reload 
(vpenv) ~/vp/vp$ sudo systemctl start gunicorn
(vpenv) ~/vp/vp$ sudo systemctl enable gunicorn
(vpenv) ~/vp/vp$ sudo systemctl restart nginx

sudo systemctl daemon-reload
sudo systemctl start gunicorn
sudo systemctl enable gunicorn
sudo systemctl restart nginx

所以我检查了gunicorn的状态：

(vpenv) ~/vp/vp$ sudo systemctl status gunicorn

并获取错误：

 gunicorn.service - gunicorn daemon
   Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)

我已经在~./bashrc（和did source~./bashrc）和virtualenv activate文件（和did source vpenv/bin/activate）中放置了我的密钥

找不到.sock文件

一些注意事项：

之前，我遇到了另一个gunicorn无法启动的错误，我的gunicorn和nginx配置路径如下所示：

[Service]
Environment=VP_SECRET_KEY=<value>

古尼康：

WorkingDirectory=/home/tony/vp/
    ExecStart=/home/tony/vp/vpenv/bin/gunicorn --workers 3 --bind unix:/home/tony/vp/vp.sock vp.wsgi:application

Nginx:

location / {
                include proxy_params;
                proxy_pass http://unix:/home/tony/vp/vp.sock;
            }

正如您所看到的，路径是vp/vp.sock，而不是像现在这样的vp/vp/vp.sock

当我这样做时：

$ ps -aux | grep gunicorn

我得到：

tony     15624  0.0  0.1  12944   976 pts/3    S+   13:57   0:00 grep --color=auto gunicorn

这意味着有一个错误

mynginx错误日志文件：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")

application = get_wsgi_application()

是的，我使用多个设置文件

我不得不说，这是我第一次部署，但我尽我所能理解一切

希望你能帮忙

我创建的新用户没有访问.bashrc的权限

我所做的是将环境变量放在gunicorn.service文件中，如下所示：

[Service]
Environment=VP_SECRET_KEY=<value>

完成了
