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

继续关注@lfender6445和@SAURABH回答——

我的问题还在于，在升级到Vagrant 2.2.2之后，当客户机启动时，Apache2作为web服务器运行。在过去，我只使用nginx作为web服务器。

vagrant ssh进入机箱，并运行以下命令使Apache2在guest机箱引导时不启动:

sudo update-rc.d -f apache2 remove

退出ssh，流浪汉停下来，流浪汉起来。问题解决了。

其他回答

我通过运行:

sudo apachectl stop

结果apache在后台运行，阻止nginx在指定的端口上启动。

在Ubuntu上运行:

sudo /etc/init.d/apache2 stop

[::]: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;

用编辑器打开/etc/nginx/nginx.conf，注释掉这行-

include /etc/nginx/sites-enabled/*;

重新启动nginx，你就可以开始了!

最后一个[emerg]显示了[::]:80的重复监听选项，这意味着有多个nginx块文件包含[::]:80。

我的解决方案是删除[::]:80设置之一

附注:你可能有默认块文件。我的建议是将该文件作为端口80的默认服务器。并从其他块文件中删除[::]:80

2018-10-31 23:34:09

我的问题是我有重叠的监听指令。我设法通过运行来找出重叠的指令

grep -r listen /etc/nginx/*

两个文件在同一个端口监听:

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