Nginx Reverse Proxy Configuration

1. Config Nginx

open your nginx configuration file ( at /etc/nginx/sites-available/default under ubuntu ), add a server :

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /wings/sqlflow/frontend/;
    index index.html;

    location ~* ^/index.html {
        add_header X-Frame-Options deny; # remove this line if you want embed sqlflow in iframe
        add_header Cache-Control no-store;
    }

    location / {
        try_files $uri $uri/ =404;
    }

    location /api/ {
        proxy_pass http://127.0.0.1:8081/;
        proxy_connect_timeout 600s ;
        proxy_read_timeout 600s;
        proxy_send_timeout 600s;

        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 User-Agent $http_user_agent;  
    }
}

note that 8081 in proxy_pass http://127.0.0.1:8081/ should be consistent to gspLive.jar's port.

/api is mapped to http://127.0.0.1:8081 in the above configration. This is useful if you company doesn't allow access 8081 port from the external.

2. modify frontend configuration file config.private.json

  • Open the configration file "/wings/sqlflow/frontend/config.private.json"
  • Modify the ApiPrefix attribute
1
  "ApiPrefix": "/api"

Customize the port

If you don't want to change the default service port you can just ignore this section. Otherwise this section will show you how to customize the port.

1. Default port

  1. Web port is 80
  2. SQLFlow backend service port:
File Port
eureka.jar 8761
gspLive.jar 8081
sqlservice.jar 8083

2. Modify the web port

Change the default web port from 80 to 9000 (or any port you like).

3. Modify java service port

Change the default gspLive port from 8081 to 9001(or any port you like).

Step 1: Change the port in nginx config file

Step 2: Change the port in gspLive.sh(gspLive.bat)

Start Frontend Services

start your nginx :

1
sudo service nginx start

or reload :

1
sudo nginx -s reload
