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

我用nginx运行Varnish服务器。我的varnish服务器运行在端口80上,因此,我的nginx服务器没有启动。我在所有nginx配置文件中将端口更改为8088,但我的default.conf文件在/etc/nginx/conf中。d目录下的Ubuntu服务器。

由于我的conf.d目录包含在主/etc/nginx.conf文件中,nginx没有启动。

将“/etc/nginx/conf.d/default.conf”重命名为“/etc/nginx/conf.d/default.conf”。/etc/nginx/conf.d/*.conf;从我的nginx.conf文件。

其他回答

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。

多个服务可以在同一个端口上侦听。 这个问题通常来自于在同一台机器上混合使用Apache和NGINX。

检查:

Sudo netstat -plant | grep 80

停止Apache并重启NGINX:

Sudo systemctl stop apache2 && Sudo systemctl restart nginx && Sudo systemctl status nginx

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。

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。

在我的例子中,罪魁祸首是一个服务器块,它包含:

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

在Linux上,侦听特定IP的套接字(例如[::1]:80)与侦听同一端口但任何IP的套接字(例如[::]:80)发生冲突。通常nginx会在幕后使用一个套接字来透明地处理这个问题。然而,在listen指令上显式指定ipv6only(或某些其他选项)会迫使nginx(尝试)为它创建一个单独的套接字,从而导致Address already in use错误。

由于ipv6only=on是默认的(自1.3.4以来),修复只是简单地从这个指令中删除该选项,并确保ipv6only不在我的配置中的其他任何地方使用。
