Nginx with Docker : nginx: [emerg] unknown directive "enable" in /etc/nginx/nginx.conf

Question

我有两台服务器，一台在数字海洋上，另一台在其他地方。我有一个项目，它与该服务器上的所有应用程序配合良好。但是，我想创建一个 droplet 并将其移动到数字海洋，所以我通过 sudo scp 命令将所有文件复制到新服务器（数字海洋）。除了 Nginx 返回退出代码 1 之外，所有服务都运行良好，如下图所示。整个代码都是一样的，所以我很困惑为什么它不能像另一个一样工作。

我可以知道我可能遗漏了什么吗？

这是我的 nginx.conf 文件 :

worker_processes 4;
    
    events {
      worker_connections 4096;
    }
    
    http {
    
      server {
        listen 80 default_server;
        server_name "";
        return 444;
      }
    
      server {
        server_name game-dev.myappapp.com;
    
        location / {
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header Host $http_host;
          proxy_set_header X-NginX-Proxy true;
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection "upgrade";
    
          proxy_pass http://game_nodes;
          proxy_redirect off;
        }
      }
      server {
        if ($host = game-dev.myappapp.com) {
          return 301 https://$host$request_uri;
        }
    
    
        listen 80;
        listen [::]:80;
        server_name game-dev.myappapp.com;
        return 404;
      }
    
      upstream game_nodes {
        # enable sticky session
        #ip_hash;
        server game-alpha:3000;
        keepalive 8;
      }
    
      server {
        server_name api-dev.myappapp.com;
    
        location / {
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header Host $http_host;
          proxy_set_header X-NginX-Proxy true;
    
          proxy_pass http://main_nodes;
          proxy_redirect off;
    
        }
      }
    
      server {
        if ($host = api-dev.myappapp.com) {
          return 301 https://$host$request_uri;
        }
    
        listen 80;
        listen [::]:80;
        server_name api-dev.myappapp.com;
        return 404;
      }
    
      upstream main_nodes {
        server main-alpha:8000;
        server main-beta:8000;
        keepalive 8;
      }
    }

这是我的 Dockerfile :

FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf

正如你从下面的截图中看到的（左边的服务器是我的 droplet，右边的是我的另一台服务器）我的 droplet 没有正常监听 80 端口它应该监听另一台服务器的 80 端口。

这是我来自 DigitalOcean Droplet 的 Nginx 日志。

是nginx.co.conf来自DigitalOcean droplet:

    root@knowin-project-dev:/home/cihat/app# docker run -it nginx /bin/bash 
    root@1c54013ff2c8:/# cat etc/nginx/nginx.conf 
    user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

注意：ufw 的状态为未激活。所以所有端口都可用。

阅读错误信息：

2021/06/13 20:22:46 [emerg] 1#1: unknown directive "enable" in /etc/nginx/nginx.conf:45
nginx: [emerg] unknown directive "enable" in /etc/nginx/nginx.conf:45

您的配置文件中存在语法错误 #45 您共享的配置文件在第 45 行看起来不错，因为您的“启用粘性会话”已用 # 符号注释掉。

通过输入

确保运行容器中的配置文件是相同的

docker exec nginx /bin/bash -c "cat /etc/nginx/nginx.conf" | tee nginx.co.conf

在您的数字海洋服务器上。请分享 nginx.co.conf 文件的输出，并确保第 45 行也被注释掉。

您是如何部署 docker-容器的？您是否将它们导出为 tar 并上传到新服务器？听起来你的本地容器和数字海洋上的容器有些不同。
