python - django 项目 nginx : connect() failed (111: Connection refused) while connecting to upstream ubuntu server on Digital Ocean

Question

请帮帮我，我使用 django + gunicorn + nginx，但出现错误
nginx:连接到上游时连接()失败(111:连接被拒绝)
我认为问题是9000端口？如何解决这个问题呢？
502 Bad Gateway

你似乎还没有开始 unicorn 。既然你已经为它制作了一个初始化脚本，你应该做 sudo start gunicorn .
