两个 Node 应用,一个 Nginx 服务器

两个 Node 应用,一个 Nginx 服务器

我是 Nginx 的新手,但它似乎并不复杂。我有两个节点应用程序(使用 forever),一个在端口 2368 上运行(域 A),另一个在 2367 上运行(sub.domainB)。

domainA 工作正常。但是 sub.domainB 报告 502 错误。

这是我的配置文件:

服务器运行的是 Ubuntu 15.04

/etc/nginx/nginx.conf

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;

        server_names_hash_bucket_size 64;

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

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##

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

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

        ##
        # Virtual Host Configs
        ##

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

etc/nginx/sites-available/domainA.com

server {
    listen 80;

    server_name domainA.com;

    location / {
        proxy_pass http://my_ip:2368;
        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;
    }
}

etc/nginx/sites-enabled/sub.domainB.com

server {
    listen 80;

    server_name sub.domainB.com;

    location / {
        proxy_pass http://my_ip:2367;
        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;
    }
}

上述配置是正确的,但是,在我的应用程序中,我指向位于 sub.domainB.com 的节点应用程序的生产环境中的 127.0.0.1。将其更改为机器的 IP 地址(与其他节点应用程序一样)解决了该问题。
