nginx子域使用node.js应用程序反向代理

Question

我有3个Node.js应用。客户端，管理员和API。我还有子域：example.com，admin.example.com和api.example.com。 我也有nginx配置，但它不起作用（在我看来） 当我输入api.example.com时，它会加载example.com的内容，但是当我用端口编写子域时，它的工作原理是：api.example.com：8081

在客户端，我使用angular.js，也许这里有问题，但我不这么认为......

这是我的nginx conf：/ etc / nginx / sites-avaliable / default：

server {
    listen 80;
    server_name example.com;
    rewrite ^ https://$http_host$request_uri? permanent;

    location / {
        proxy_pass http://127.0.0.1:443;
        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_connect_timeout 150;
        proxy_send_timeout 100;
        proxy_read_timeout 100;
        proxy_buffers 4 32k;
        client_max_body_size 8m;
        client_body_buffer_size 128k;
    }
}

server {
    listen 80;
    server_name api.example.com;
    rewrite ^ https://$http_host$request_uri? permanent;

    location / {
        proxy_pass http://127.0.0.1:8081;
        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_connect_timeout 150;
        proxy_send_timeout 100;
        proxy_read_timeout 100;
        proxy_buffers 4 32k;
        client_max_body_size 8m;
        client_body_buffer_size 128k;
    }
}

server {
    listen 80;
    server_name admin.example.com;
    rewrite ^ https://$http_host$request_uri? permanent;

    location / {
        proxy_pass http://127.0.0.1:8082;
        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_connect_timeout 150;
        proxy_send_timeout 100;
        proxy_read_timeout 100;
        proxy_buffers 4 32k;
        client_max_body_size 8m;
        client_body_buffer_size 128k;
    }
}
