Question

我在单个管理页面上遇到502 Bad Gateway错误： http://Domain.com/admin/sitecategory/add/

虽然所有其他管理页面都运行良好。我检查了django日志，没有错误。我运行了django测试服务器，并且该特定页面也正常工作。

nginx日志：

2013/06/15 13:37:01 [error] 1906#0: *4431 upstream prematurely closed connection while reading response header from upstream, client: 46.185.176.26, server: staging.myapp.com, request: "GET /admin/sitecategory/add/ HTTP/1.1", upstream: "uwsgi://unix:///tmp/myapp-staging.socket:", host: "staging.myapp.com", referrer: "http://staging.myapp.com/admin/sitecategory/"

DAMN ! worker 1 (pid: 1942) died, killed by signal 9 :( trying respawn ...

我使用upstart运行uwsgi：

exec uwsgi -b 25000 --chdir=/www/python/apps/myapp-staging/ --module=wsgi:application --env DJANGO_SETTINGS_MODULE=settings --socket=/tmp/myapp-staging.socket --processes=3  --harakiri=10  --max-requests=5000  --vacuum --master --pidfile=/tmp/myapp-staging-master.pid --uid=220 --gid=499 --daemonize=/www/uwsgi/myapp-staging.log

和我的nginx配置如下：

server {
    server_name staging.myapp.com;

    root /www/python/apps/myapp-staging/;



    access_log /www/nginx/staging.myapp.com.access.log;
    error_log /www/nginx/staging.myapp.com.error.log;

    location /static/ {
        alias /www/python/apps/myapp-staging/static/;
        expires 30d;
    }

    location /media/ {
        alias /www/python/apps/myapp-staging/media/;
        expires 30d;
    }

    location / {
        uwsgi_pass unix:///tmp/myapp-staging.socket;
        include uwsgi_params;
        proxy_read_timeout 360;
    }
}

我在这里做错了什么？

由于

Answer 1

在nginx配置文件中找到一个错误

        proxy_read_timeout 360;

应该阅读

        uwsgi_read_timeout 360;

HttpUwsgiModule模块有自己的超时指令。

http://wiki.nginx.org/HttpUwsgiModule#uwsgi_read_timeout

Answer 2

你设置了10秒harakiri的重视，很可能需要更多的时间。

只需删除它，衡量视图需要多长时间并相应地重置
