Nginx试图在端口80上运行，但托拉斯已被移除。

Question

我有一台用清漆运行nginx的服务器。我不能在运行nginx和清漆的同时，他们都试图监听端口80。

nginx配置为侦听端口8080。

        upstream www {
        server 127.0.0.1:9001;
    }
    server {
        listen 8080 default_server;
        server_name server.com;
        root /var/www/html/;
    location /docs/index.php {
            fastcgi_pass www;
            fastcgi_split_path_info ^(.+\.php)(/.*)$;
            include fastcgi_params;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param  HTTPS off;
            fastcgi_param  SERVER_PORT 8888;
        }
}

清漆然后监听端口80。

             -s ${VARNISH_STORAGE}"

当我尝试重新启动nginx时，我会得到一个错误。

service nginx restart
Stopping nginx:                                            [FAILED]

nginx: [emerg] still could not bind()

如果我停止清漆并运行netstat，我可以看到nginx运行在端口8080和80上。

netstat -tulpn | grep nginx
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      95831/nginx
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN      95831/nginx

检查nginx config目录，我看不到定义端口的任何地方。

grep -rnw '/etc/nginx/' -e '80'  


grep -rnw '/etc/nginx/' -e 'server'

检查所有Server块都有侦听指令，否则nginx将默认为该块的80。
