用於節點應用程序的Nginx反向代理子域

Question

我對NGINX配置非常陌生。 我瀏覽了許多帖子，尋找其他遇到此問題並找到了可行解決方案的人。

我有2個node.js Web應用程序，它們將在2個單獨的端口（例如81, 82 ）上運行。

我最初的意圖是使用反向代理，以便訪問者可以訪問相同的物理盒子，但是根據所使用的域為他們提供不同的內容。

我成功地將站點根據其域分開進行渲染。 其中一個應用程序有一個app.exampleb.com綁定的子域（ app.exampleb.com ），似乎我app.exampleb.com嘗試訪問該子域時，nginx都會為我提供一個頁面，指出“我已成功配置了服務器” .....謝謝nginx

我已經在我的nginx.conf文件中放置了以下內容：

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

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

    ##
    # Logging Settings

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##
    # Gzip Settings

    gzip on;
    gzip_disable "msie6";

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    server {
        listen       80;
        server_name  examplea.com;

         location / {
        proxy_pass http://localhost:81;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    }

    server {
            listen       80;
            server_name  app.examplea.com;

             location / {
        proxy_pass http://localhost:81;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
        }


    server {
        listen       80;
        server_name  exampleb.com;

        location / {
         proxy_pass http://localhost:82;
        }
    }

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

完整的配置應該是這樣的：

server {
    listen 80;

    server_name example.com;

    location / {
        proxy_pass http://localhost:81;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

將其放在nginx.conf的http {}指令中

記得重啟nginx
