我正在尝试使用Gunicorn / WSGI / Nginx部署FlaskApp。我一直在尝试使它工作一段时间,除了遵循T的《数字海洋》指南之外,找不到其他任何东西。以下是我目前所处状态的文件。我已经尝试对mywebapp.service
文件进行了几种不同的调整,因为我很确定这就是问题所在。我可以运行/bin/gunicorn --workers 3 --bind 0.0.0.0:8000 -u nginx -g nginx wsgi
,并且gunicorn将起作用。我很确定自己缺少了一些很小但可能是基本的东西,但我输了。我的nginx
用户拥有该应用程序目录。

我终于发现我可以查看journalctl
并找到实际的日志。我必须为chown
用户使用nginx
的gunicorn文件。现在它可以工作了,我只是要调整我的Nginx东西,导致它找不到东西该死的套接字。

根据提供的答案,这是我如何解决的方法。
导航到您的virtualenv,如下所示
cd / my-env / bin /
知道当前使用情况(在gunicorn.service文件上指定用户)
下面的示例在/etc/systemd/system/gunicorn.service文件中将用户作为“ sammy”
[Service]
User=sammy
Group=www-data
WorkingDirectory=/home/sammy/myprojectdir
ExecStart=/home/sammy/myprojectdir/myprojectenv/bin/gunicorn \
在bin文件夹上,运行命令ls确认您具有文件'gunicorn'
使用此Linux命令终止文件
sudo chown sammy gunicorn
运行以下命令以重启gunicorn并确认
sudo systemctl启用gunicorn sudo systemctl启动gunicorn sudo systemctl status枪色
