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

我有几个*。保存文件(紧急转储从nano)从不同的NGINX配置文件在my sites- available目录。一旦我删除了这些.save文件，NGINX重新启动正常。我以为这些是无害的，因为没有相应的符号链接，但我想我错了。

其他回答

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:)

我在letsencrypt (certbot)和nginx中遇到了同样的问题，

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

此错误还没有解决方案

因此，a更改了一个cron为renew(在renew后重新加载)(使用certbot的建议)

-- in /etc/cron.d/certbot
from
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew 
to
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew --pre-hook "service nginx stop" --post-hook "service nginx start"

问题——我有这个问题。基本上，我所做的就是用正常的nginx命令启动nginx，然后尝试用service nginx reload / restart重新启动nginx，然后我得到这个错误

解决方案-使用nginx -s stop停止nginx，然后重新启动nginx服务器使用服务nginx重启问题解决。

2022-10-28 09:03:18

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。
