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] still could not bind()
   ...done.
   ...done.

如果我跑步

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

我什么都没有。80端口上没有任何内容

然后我运行以下命令：

sudo netstat -pan | grep ":80"

我很沮丧 我该如何调试？

我正在将uwsgi与端口8070上的代理传递一起使用。uwsgi正在运行。Nginx不是。我正在使用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

[::]:80 是ipv6地址。

如果您的nginx配置正在侦听端口80和port，则可能导致此错误[::]:80。

我的默认网站可用文件中包含以下内容：

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

您可以通过添加如下内容ipv6only=on来解决此[::]:80问题：

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

有关更多信息，请参见：

http://forum.linode.com/viewtopic.php?t=8580

http://wiki.nginx.org/HttpCoreModule#listen

我通过运行解决了这个问题 sudo apachectl stop -事实是apache在后台运行，并阻止了nginx在所需端口上启动。

在ubuntu上运行 sudo /etc/init.d/apache2 stop

我的情况不同，我必须终止运行Nginx才能重新启动它。

代替

sudo systemctl restart nginx

我不得不使用：

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

我发现了从未有过的问题。

我只需要删除/etc/nginx/sites-available/default。然后它起作用了。

我的conf在/etc/nginx/default。

我也遇到了同样的错误。

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

当我在浏览器中输入本地主机时，我正在

有用！

这是此服务器的默认网页。

Web服务器软件正在运行，但尚未添加任何内容。apache2不在同一端口上运行，而不是nginx欢迎页面，

1. 找到apache2 ports.conf文件

   sudo /etc/apache2/ports.conf
   

2. 然后更改其他端口80，我将其设置为70

3. 保存文件

4. 重新启动系统

它也将为您工作，如果您在浏览器中键入localhost，您将获得nginx欢迎页面

尝试执行此命令

sudo fuser -k 443/tcp
service nginx restart

我的问题是我有重叠的监听指令。我已经设法通过运行找出重叠的指令

grep -r listen /etc/nginx/*

两个文件在同一端口上监听：

/etc/nginx/conf.d/default.conf:           listen 80;  
/etc/nginx/sites-enabled/default.conf:    listen 80;

我在letencrypt（certbot）和nginx中遇到了同样的问题，

参考：https : //github.com/certbot/certbot/issues/5486

此错误尚无解决方法

因此，更改了cron以进行续订（在续订后重新加载）（使用certbot的建议）

-- in /etc/cron.d/certbot

首先将/etc/apache2/ports.conf中的apache监听端口80更改为8080 apache

Listen 1.2.3.4:80 to 1.2.3.4:8080
sudo service apache2 restart 

要么

sudo service httpd restart    // in case of centos

然后将nginx添加为将监听apache端口的反向代理服务器

server {
 listen   1.2.3.4:80;
 server_name  some.com;

 access_log  /var/log/nginx/something-access.log;

 location / {
  proxy_pass http://localhost:8080;
  proxy_redirect off;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 }


location ~* ^.+\.(jpg|js|jpeg|png)$ {
   root /usr/share/nginx/html/;
}

location /404.html {
  root /usr/share/nginx/html/40x.html;
}

error_page 404 /404.html;
    location = /40x.html {
}

error_page 500 502 503 504 /50x.html;
    location = /50x.html {
}

# put code for static content like js/css/images/fonts
}

更改后重新启动Nginx服务器

sudo service nginx restart

现在，所有流量将由nginx服务器处理，并将所有动态请求发送到apache，而静态内容则由nginx服务器提供服务。

对于像cache这样的高级配置：

我遇到了类似的问题。日志如下

最后一个[emerg]表明，duplicate listen options for [::]:80这意味着有多个Nginx块文件包含[::]:80。

我的解决方案是删除 [::]:80设置

PS您可能具有默认的阻止文件。我的建议是将此文件保留为端口80的默认服务器。并[::]:80从其他阻止文件中删除

我使用超级用户在Docker容器上并排运行Nginx和Gunicorn。

这是用于主管的配置：

[supervisord]
nodaemon=true

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


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

问题是我如何启动Ngnix：默认情况下，它在前台运行。这使得监督重试以运行另一个Nginx实例。

通过添加-g 'daemon off;'到命令行，Nginx停留在前台，主管停止尝试运行另一个实例。

就我而言，其中一个服务（Apache，Apache2或Nginx）已经在运行，因此我无法启动另一个服务。

我的站点目录中有来自不同NGINX配置文件的多个* .save文件（来自nano的紧急转储）。删除这些.save文件后，NGINX重新启动正常。由于没有相应的符号链接，我认为这些代码是无害的，但我想我错了。

要继续@ lfender6445和@SAURABH的答案-

我的问题还在于，在升级到Vagrant 2.2.2之后，来宾引导时Apache2作为Web服务器运行。过去，我只有nginx作为Web服务器。

将vagrant ssh放入框中，并在访客箱启动时运行以下命令以禁止Apache2启动：

sudo update-rc.d -f apache2 remove

退出ssh，无所适从，无所适从。问题解决了。

如果尝试上述任何一种方法后问题仍然存在，请重新启动服务器一次。它为我工作:)

在我看来，罪魁祸首是一个包含以下内容的服务器块：

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

在Linux上，侦听特定IP（例如[::1]:80）的套接字与侦听同一端口但侦听任何IP（即[::]:80）的套接字冲突。通常，nginx将通过在幕后使用单个套接字来透明地处理此问题。但是，ipv6only在listen指令上显式指定（或某些其他选项）会迫使nginx（尝试）为其创建单独的套接字，从而导致Address already in use错误。

由于ipv6only=on无论如何都是默认设置（自1.3.4起），解决方法是从该指令中删除该选项，并确保ipv6only未在我的配置中使用该选项。

我有同样的问题，但是我看到Nginx监听了端口80：

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

但是，当我尝试重新启动它时，出现错误：

    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中，我设置了PID文件，似乎系统无法正确捕获它：

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

当我删除它时，它起作用了。
