下面给出的是我的 /etc/nginx/sites-available/default 文件。我添加了两个新的位置 block 及其各自的本地主机链接,只有根位置 block (本地主机 8000)由 nginx 作为服务器。另外两个链接不起作用。

示例

http://111.111.111.111 = Works
http://111.111.111.111/app1 = Doesn't work
http://111.111.111.111/app2 = Doesn't work
http://111.111.111.111:3000 = Doesnt't work
http://111.111.111.111:4000 = Doesnt't work

如何修复以下文件,以便可以访问在三个端口(3000、4000 和 8000)上运行的三个 Node 应用程序。预先感谢您的帮助

最佳答案

有关完整配置,请查看我对 Configuring Load Balancer to Route to different pages of instance? 的回答。您不需要 root/var/www/html; 因为您不提供静态 html 页面。

您需要正确的转发 header :

location /app1 {
proxy_pass http://localhost:4000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}

您还应该在localhost上使用127.0.0.1,并为每个上游node.js服务器创建一个 block ,nginx充当反向代理:

upstream root {
server 127.0.0.1:8000;
keepalive 256;
}

upstream app1 {
server 127.0.0.1:4000
keepalive 256;
}

upstream app2 {
server 127.0.0.1:3000
keepalive 256;
}

server {
listen 80 default_server;

location / {
proxy_pass http://root;
proxy_pass_header Access-Control-Allow-Origin;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass_header Set-Cookie;
proxy_pass_header X-UA-Compatible;
proxy_pass_header Server;
proxy_buffers 64 16k;
proxy_buffer_size 16k;
proxy_busy_buffers_size 64k;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_read_timeout 10;
proxy_redirect off;
}

location /app1 {
proxy_pass http://app1;
proxy_pass_header Access-Control-Allow-Origin;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass_header Set-Cookie;
proxy_pass_header X-UA-Compatible;
proxy_pass_header Server;
proxy_buffers 64 16k;
proxy_buffer_size 16k;
proxy_busy_buffers_size 64k;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_read_timeout 10;
proxy_redirect off;
}

location /app2 {
proxy_pass http://app2;
proxy_pass_header Access-Control-Allow-Origin;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass_header Set-Cookie;
proxy_pass_header X-UA-Compatible;
proxy_pass_header Server;
proxy_buffers 64 16k;
proxy_buffer_size 16k;
proxy_busy_buffers_size 64k;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_read_timeout 10;
proxy_redirect off;
}
}
