Gunicorn 不在 AWS EC2 上创建 .sock 文件

Posted 2023-02-24

【中文标题】Gunicorn 不在 AWS EC2 上创建 .sock 文件

【英文标题】：Gunicorn not creating .sock file on AWS EC2

【发布时间】：2019-02-09 08:26:07

【问题描述】：

我坚持按照本教程创建 Django Web 应用程序： https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04#check-for-the-gunicorn-socket-file

我想我已经阅读了关于 SO 的所有相关问题：

django gunicorn sock file not created by wsgi

Gunicorn not generating sock file

https://github.com/benoitc/gunicorn/issues/1166

他们都没有帮助。

我完全按照描述执行每个步骤，但仍未创建 myapp.sock 文件。

主项目目录为/home/ubuntu/puchalatravel 内容：

ubuntu@ip-172-31-35-104:~/puchalatravel$ ls -l

访问文件夹：

我跑了

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

多次，没有任何效果。

sudo systemctl status gunicorn的输出

这可能与 AWS EC2 设置有关吗？ Gunicorn 将页面直接提供到端口 8000，但不通过套接字，因为它不是创建的。

【参考方案1】：

您的 gunicorn.service 文件将 gunicorn 配置为在“/home/puchalatravel/puchalatravel.sock”而不是“/home/ubuntu/puchalatravel/puchalatravel.sock”中创建文件。
