Nginx 报 500 号错误

[waterlaw]

服务端采用 Django + Nginx + Gunicorn 部署， 每次访问 /articles/{id} 这个接口时就报 500/502/504 错误。nginx 错误文件：

Gunicorn 控制台的错误日志：

upstream 设置的不对吧

[Beebird]

django 有日志输出吗？ 有条件的话试试直接访问 django 的监听端口

想花式 500 ？
你得跟着 V2EX 多学学😂

排查两方面，一个关闭防火墙试试，同时注意关闭 selinux 试试。

http://unix:/... 肯定连不上啊。。

proxy_pass 配错了吧，upstream 那块的问题

[waterlaw]

不知道是不是文件句柄太多， 每次修改完都再次开启 gunicorn, 然后开了多个进程。 重启一下突然好了， 想到博客用了结巴分词， 然后缓存的时候占用了 1.5 秒。
