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

对我来说，问题是我在用Supervisor和Systemd运行一个应用程序。在应用程序与Supervisor运行时，我有一个配置文件来处理Nginx。我停止了这个过程，重新启动了监督者。

现在Nginx由Systemd推出，我不再有这个问题了。

[::]:80是ipv6地址。

如果你有一个nginx配置，监听端口80和端口[::]:80，就会导致这个错误。

我有以下在我的默认网站可用文件:

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

你可以通过添加ipv6only=on到[::]:80来解决这个问题，就像这样:

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

首先修改apache监听端口80为8080 在/etc/apache2/ports.conf中包含Apache

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

sudo service httpd restart    // in case of centos

然后添加nginx作为反向代理服务器，将监听apache端口

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
}

修改后重启nginx服务器

sudo service nginx restart

现在所有流量都将由nginx服务器处理，并将所有动态请求发送到apache，静态内容由nginx服务器提供。

对于像缓存这样的高级配置:

如果在尝试上述任何解决方案后问题仍然存在，请重新启动服务器一次。这对我很有用:)

我知道这是旧的，但也要确保没有一个docker集装箱已经在80端口。那是我的问题。
