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。

其他回答

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"

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

2013-02-24 12:47:22

我通过跑步来解决

sudo killall apache2

sudo fuser -k 443/tcp

最后

sudo service nginx start
2021-03-19 11:06:38

请尝试执行该命令

sudo fuser -k 443/tcp
service nginx restart

fuser命令将找到进程id(PID)， -k标志将杀死进程，使nginx重新启动。

2018-03-29 04:49:23

我的情况不同，我必须杀死正在运行的Nginx进程来重新启动它。

而不是

sudo systemctl restart nginx

我不得不使用:

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