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

Question

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.

如果我跑了

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

我一无所获。端口 80 上没有任何内容

然后我运行以下命令：

sudo netstat -pan | grep ":80"

我被难倒了。我该如何调试这个？

我在端口8070上使用代理传递的uwsgi。uwsgi正在运行。Nginx不是。我正在使用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;
                 }
        }

这是我如何在ubuntu 12.04上安装ngin x

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

Answer 1

[：：]：80 是 IPv6 地址。

如果您有一个ngin x配置正在侦听端口80和端口[::]： 80，则可能会导致此错误。

我的默认站点可用文件中有以下内容：

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

您可以通过将ipv6只=on添加到[::]： 80来解决此问题，如下所示：

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

Answer 2

我的情况不同，我必须终止正在运行的Nginx进程才能重新启动它。

而不是

sudo systemctl restart nginx

我不得不使用:

sudo pkill -f nginx & wait $!
sudo systemctl start nginx

Answer 3

我通过运行修复了这个问题：

sudo apachectl stop

结果是apache在后台运行，阻止了nginx在期望的端口上启动。

在Ubuntu上，运行：

sudo /etc/init.d/apache2 stop
