代码更新/主机更改: 1)“点安装主管”。 [在 venv/bin 中创建了 'supervisord' 和 'supervisorctl']
2) 'sudo mkdir -p /etc/supervisor/conf.d'
3) 'sudo vim /etc/supervisor/conf.d/project.conf'
4) 'sudo vim /etc/supervisor/supervisord.conf'
5) gunicorn project.wsgi:application --bind localhost:8000

你能告诉我如何解决这个问题吗? [当我点击 52.xx.xx.xx 时,我想显示 file1.html 而不是 /usr/share/nginx/html/index.html 页面。目前,我看到的是 403.html 页面]
【问题讨论】:
【参考方案1】:Nginx 用于静态文件。对于 django 项目,您需要安装应用程序服务器,例如 uwsgi
或 gunicorn
它将按以下逻辑运行:user <-> nginx <-> app_server <-> django
这是 nginx + gunicorn + django 的指南http://tutos.readthedocs.org/en/latest/source/ndg.html
用于 cmets 的 UPD 给你一些配置,也许有帮助。 Nginx
server
listen 80;
server_name your_public_ip;
access_log /var/log/nginx/your_nginx.log;
location /media
alias /home/ubuntu/Project/project/media;
#It is path to your media, you can check this by 'pwd' command
location /static
alias /home/ubuntu/Project/project/static_root;
#same
location /
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $server_name;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
安装 gunicorn 并由主管自动启动sudo apt-get install supervisor
打开文件
sudo vim /etc/supervisor/conf.d/project.conf
并编写此配置
[program:project] #by this name you will call supervisor
command=/home/ubuntu/venv/bin/gunicorn --bind localhost:8000 project.wsgi:application
enviroment=PYTHONPATH=/home/ubuntu/venv/bin #path to virtualenv
directory=/home/ubuntu/project_folder/project #you path to project
user=ubuntu #your user
开始吧
sudo supervisorctl start project
也是主管的命令:sudo supervisorctl reload
sudo supervisorctl status
sudo supervisorctl reread
sudo supervisorctl update
【讨论】:
“项目”路径是否必须为:/var/www/? 当我尝试从路径 '/home/ec2-user/project/' 运行 'gunicorn project.wsgi:application' 时,它会抛出一个很长的错误跟踪:venv/local/lib/ python2.7/site-packages/gunicorn/arbiter.py",第 515 行,在 spawn_worker worker.init_process() ImportError: No module named wsgiNo module named wsgi
wsgi 它是 django 中的应用程序文件的名称,包含在项目文件夹中,靠近 settings.py
,你从错误的路径中调用它。因此,为艰巨的任务做好准备。当我第一次上传时,我整天都在这样做。我建议您逐步完成教程中的所有事情,以及您将拥有的谷歌错误
当我尝试命令:'systemctl enable gunicorn_project'时,它说 -bash: systemctl: command not found。您能否就如何安装它提供一些替代/建议?
你可以在google上查,这个问题,会在第一页。但老实说我不使用它,你停留在哪一步?你需要配置nginx,配置gunciorn,然后在supervisor中添加这个,phoro自动启动。您可以查看另一个指南来解决这个问题,当我第一次这样做时,我会阅读 3 或 4 个指南 :)以上是关于在 AWS EC2 主机上托管 Django 应用程序的主要内容,如果未能解决你的问题,请参考以下文章
