nginx - nginx: [emerg] bind() 到 [::]:80 失败（98: 地址已在使用中）

突然我收到以下 nginx 错误

 * Restarting nginx
 * Stopping nginx nginx
   ...done.
 * Starting nginx nginx
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
   ...done.
   ...done.

如果我跑

lsof -i :80 or sudo fuser -k 80/tcp 

我什么也没得到。 80端口上没有任何东西

然后我运行以下命令：

sudo netstat -pan | grep ":80"

我很困惑。我该如何调试这个？

我在端口 8070 上使用带有代理通行证的 uwsgi。uwsgi 正在运行。 Nginx 不是。我使用的是ubuntu 12.4

以下是我的 nginx conf 文件的相关部分

upstream uwsgi_frontend {
          server 127.0.0.1:8070;
        }
server {
listen 80;
        server_name 127.0.0.1;
        location = /favicon.ico {
                  log_not_found off;
                }



                location / {
                       include uwsgi_params;
                       uwsgi_buffering off;

                       uwsgi_pass 127.0.0.1:8070;
                 }
        }

这是我在 ubuntu 12.04 上安装 nginx 的方法

nginx=stable;add-apt-repository ppa:nginx/$nginx;
apt-get update
apt get install nginx-full

我通过运行解决了这个问题：

sudo apachectl stop

事实证明 apache 在后台运行并阻止 nginx 在所需端口上启动。

在 Ubuntu 上，运行：

sudo /etc/init.d/apache2 stop
