nginx: [emerg] bind() to [::]:80 failed(98:地址已被使用)

突然我得到下面的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

我什么也得不到。80端口上没有东西

然后我运行如下:

sudo netstat -pan | grep ":80"

我被难住了。我如何调试这个?

我在端口8070上使用带有代理通道的uwsgi。Uwsgi正在运行。Nginx则不然。我使用的是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;
                 }
        }

下面是我在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

当前回答

我使用supervisor在Docker容器上并排运行Nginx和Gunicorn。

这是用于supervisor的配置:

[supervisord]
nodaemon=true

[program:gunicorn]
command = /project/start.sh
user = www-data

[program:nginx]
command=/usr/sbin/nginx

问题是我如何在默认情况下启动Ngnix，它在前台运行。这使得管理器重试运行另一个Nginx实例。

你可以通过在命令行中添加-g 'daemon off;'或daemon off;在配置文件的顶部，Nginx停留在前台，supervisor停止尝试运行另一个实例。

其他回答

我也有同样的问题，但我看到Nginx监听了80端口:

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      9730/nginx

但是当我试图重新启动它时，我有错误:

    service nginx restart
Stopping nginx:                                            [FAILED]

nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)
nginx: [emerg] still could not bind()

我的问题是在配置文件，我设置PID文件，似乎系统不能正确捕获它:

user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

当我取出它时，它工作了。

我发现了以前从未有过的问题。

我只需要删除/etc/nginx/sites-available/default。然后就成功了。

此删除将只删除符号链接，作为备份，您可以在默认文件中找到 /etc/nginx/sites-enabled /违约

我的conf在/etc/nginx/default

我通过跑步来解决

sudo killall apache2

sudo fuser -k 443/tcp

最后

sudo service nginx start

在我的例子中，罪魁祸首是一个服务器块，它包含:

        listen  127.0.0.1:80;
        listen  [::1]:80 ipv6only=on;
        server_name  localhost;

在Linux上，侦听特定IP的套接字(例如[::1]:80)与侦听同一端口但任何IP的套接字(例如[::]:80)发生冲突。通常nginx会在幕后使用一个套接字来透明地处理这个问题。然而，在listen指令上显式指定ipv6only(或某些其他选项)会迫使nginx(尝试)为它创建一个单独的套接字，从而导致Address already in use错误。

由于ipv6only=on是默认的(自1.3.4以来)，修复只是简单地从这个指令中删除该选项，并确保ipv6only不在我的配置中的其他任何地方使用。

在Ubuntu上对我有效的快速解决方案。首先找到当前运行的nginx实例:

PS 辅助 |格雷普·恩金克斯

复制pid(例如123456)并运行

杀死-9 123456
