无法重启nginx

Question

我在Ubunto 10:04上使用nginx和Django.问题是,当我重新启动nginx时,我收到此错误.

sudo /etc/init.d/nginx restart
Restarting nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
configuration file /etc/nginx/nginx.conf test is successful
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

此外,我已经尝试停止然后启动但仍然得到错误.

这是lsof的输出:

sudo lsof -i tcp:80
COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   27141   root    6u  IPv4 245906      0t0  TCP *:www (LISTEN)
nginx   27142 nobody    6u  IPv4 245906      0t0  TCP *:www (LISTEN)

如果我使用PID 27141终止进程,它可以工作.但是,我想深究为什么我不能只重新启动.

这是nginx.conf:

worker_processes 1;

user nobody nogroup;
pid /tmp/nginx.pid;
error_log /tmp/nginx.error.log;

events {
    worker_connections 1024;
    accept_mutex off;
}

http {
    include mime.types;
    default_type application/octet-stream;
    access_log /tmp/nginx.access.log combined;
    sendfile on;

    upstream app_server {
        # server unix:/tmp/gunicorn.sock fail_timeout=0;
        # For a TCP configuration:
        server 127.0.0.1:8000 fail_timeout=0;
    }

    server {
        listen 80 default;
        client_max_body_size 4G;
        server_name _;

        keepalive_timeout 5;

        # path for static files
        root /home/apps/venvs/app1/app1;

        location / {
            # checks for static file, if not found proxy to app
            try_files $uri @proxy_to_app;
        }

        location @proxy_to_app {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;

            proxy_pass   http://app_server;
        }

        error_page 500 502 503 504 /500.html;
        location = /500.html {
            root /path/to/app/current/public;
        }
    }
}

有任何想法吗？

Answer 1

尝试:

$ sudo fuser -k 80/tcp ; sudo /etc/init.d/nginx restart 

Answer 2
