ubuntu – nginx – nginx：[emerg] bind()to [::]：80 failed(98：Address already in use)

突然我得到了下面的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

我什么都没有。没有在端口80

然后我运行下面：

sudo netstat -pan | grep ":80"

我被骗了。

如何调试？

我使用uwsgi与

代理通过端口8070.uwsgi正在运行。 Nginx不是。我使用ubuntu 12.4

下面是我的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;
                 }
        }

这里是如何在ubuntu 12.04上安装Nginx

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

[::]：80是一个ipv6地址。

如果你有一个Nginx配置监听端口80和端口[::]：80，可能会导致此错误。

我在我的默认网站 – 可用文件中有以下：

listen 80;
listen [::]:80 default_server;

你可以通过添加ipv6only = on到[::]：80这样解决这个问题：

listen 80;
listen [::]:80 ipv6only=on default_server;
