Question

此处查看了一些其他类似问题，但无法诊断问题。

我的网站偶尔会出现502 Bad Gateway Error。

我在错误日志中找到了以下内容。注意我使用Gunicorn / NGINX在Ubuntu 16.04上使用VPS服务器。

＆＃13;

ListChanged

＆＃13;

当我去检查gunicorn状态时，我得到以下内容所以看起来可能是因为某些原因失败了？：

＆＃13;

2017/02/21 01:08:29 [crit] 1247#1247: *1 connect() to unix:/home/django/chrisblog/chrisblog.sock failed (2: No such file or directory) while connecting to upstream, client: 173.48.32.62, server: 45.32.201.31, request: "GET /redditclone/ HTTP/1.1", upstream: "http://unix:/home/django/chrisblog/chrisblog.sock:/redditclone/", host: "pythoncreate.com"

＆＃13;

这是ps aux |的输出镜头grep nginx

＆＃13;

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