Start Backend Services

If your computer has more than 8G of memory, you can change the boot parameters to recommended

Please use the gspLive.sh, eureka.sh and sqlservice.sh under mac directory instead of the original one.

• /wings/sqlflow/backend/bin/gspLive.sh

#  defult and less than or equal to 8G recommended
heapsize="2g";
# greater than 8G  recommended
# heapsize="3g"; 

• /wings/sqlflow/backend/bin/eureka.sh

#  defult and less than or equal to 8G recommended
heapsize="256m";
# greater than 8G  recommended
# heapsize="512m"; 

• /wings/sqlflow/backend/bin/sqlservice.sh

#  defult and less than or equal to 8G recommended
heapsize="4g";
# greater than 8G  recommended
# heapsize="10g"; 

start service in background:

sh /wings/sqlflow/backend/bin/backend.sh

please allow 1-2 minutes to start the service.

use jps to check those 3 processing are running.

Nginx Reverse Proxy

If we set the reverse proxy path of gspLive restful service to /api

1. Config Nginx

open your nginx configuration file ( at /usr/local/etc/ngin/nginx.conf ), 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;
		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;  
	}
}

2. modify frontend configuration file config.private.json

• Open the configration file "/wings/sqlflow/frontend/config.private.json"

• Modify the ApiPrefix attribute

  "ApiPrefix": "/api"

Start Frontend Services

start your nginx :

sudo nginx

or reload :

sudo nginx -s reload

open http://yourdomain.com/ to see the SQLFlow.

open http://yourdomain.com/api/gspLive_backend/doc.html?lang=en to see the Restful API documention.

Sqlflow client api call

See sqlflow client api call

1. Get userId from gudu_sqlflow.conf

• Open the configration file "/wings/sqlflow/backend/conf/gudu_sqlflow.conf"

• The value of anonymous_user_id field is webapi userId

  anonymous_user_id=xxx

• Note: on-promise mode, webapi call doesn't need the token parameter

1. Test webapi by curl

   • test sql:

     select name from user

   • curl command:

   curl -X POST "http://yourdomain.com/api/gspLive_backend/sqlflow/generation/sqlflow" -H "accept:application/json;charset=utf-8" -F "userId=YOUR USER ID HERE" -F  "dbvendor=dbvoracle" -F "sqltext=select name from user"

   • response:

     {
       "code": 200,
       "data": {
         "dbvendor": "dbvoracle",
         "dbobjs": [
           ...
         ],
         "relations": [
           ...
         ]
       },
       "sessionId": ...
     }

   • If the code returns 401, please check the userId is set or the userId is valid.
