问题描述

最近一直在开发一个微信公众号，由于后台计算量较大，nginx常出现timeout问题，经过排查，已经解决。错误代码形如：

14:12:16 web.1  | 2014-07-17 14:12:16 [30747] [INFO] Using worker: sync
14:12:16 web.1  | 2014-07-17 14:12:16 [30752] [INFO] Booting worker with pid: 30752
14:13:21 web.1  | 2014-07-17 14:13:21 [30747] [CRITICAL] WORKER TIMEOUT (pid:30752)
14:13:21 web.1  | 2014-07-17 03:43:21 [30752] [INFO] Worker exiting (pid: 30752)
14:13:21 web.1  | 2014-07-17 14:13:21 [30841] [INFO] Booting worker with pid: 30

解决方案

更改gunicorn配置文件，我用的是supervisor，故vi /etc/supervisor/con.f/name.conf添加一行timeout = 60*60，配置完成的name.conf文件如下：

[program:test]
		
command = /home/mirror/test/bin/gunicorn app:app -b localhost:8100
directory = /home/mirror/test
timeout = 60*60
user = mirror
autostart = true
autorestart = true
redirect_stderr = true
stdout_logfile = /home/mirror/logs/supervisor.log

更改nginx配置，补充一行proxy_read_timeout 1200，nginx默认为60秒。故vi /etc/nginx/sites-enabled/test，配置完成的test文件如下：

server {
    listen 80;
    root /home/mirror/test;
    location / {
		proxy_pass http://127.0.0.1:8100;
		proxy_read_timeout 1200;
		}
    }

Done!

温馨提示: 若配置多个站点，需单独配置gunicorn.conf，然后被supervisor调用.
