Hi Sim,

The URL you specify in the --urls parameter is the address the Web APIs are to listen on (on the server machine), which most likely won't be the same URL in your PowerServer project (which communicates with the server from outside the network).

For the simplest deployment, you should just pass to --urls 0.0.0.0:<port> (this makes the Web APIs listen on all interfaces), configure your server to reverse proxy incoming requests to <port>, and then in the PowerServer project you use the URL of the server. What port to use in here depends on your server configuration. As long as the server reverse proxies to the <port> you configured on --urls you should be good.

Francisco

Hi

Are the above for development? I am working on production. Hence, i need to figure out my linux available port right?

and when compile my powerserver project, NetServer section, i just put the hostname/ip address with available port number right?

In linux based , how to run the below? Use putty? or?

Method 2: Run the app by executing the following command:

ServerAPIs.exe --urls "http://<hostname>:<port>"

Thanks.

CUrrently I had successfully using IIS as web server with API hosted on the same IIS server. So, now i wanted to move the API from IIS server to be hosted in the DB server and use Nginx as web server.  DB server OS is linux.  Hence, pleaase correct is below steps is wrong also i have two questions below.

1. Install Nginx    https://docs.appeon.com/ps2022/Installing_Nginx_Linux.html

2. Packaging the client app ->>>>> Question: Net server - WEB API URL - Host - is it the Linux server ip address?

3. Publish the PowerServer Web APIs from the SnapDevelop IDE to a folder

4. Copy the clouapp files from item2 above to Linux server    /usr/share/nginx/html

5. Copy all files from the publish folder to the linux server.  ->>> Question: May i know if anybody can tell me, which folder normally? i dnt know because the appeon document never teach this.

6. Any services need to bring up? like in IIS,, need to start client and API.

Please advice. Thanks a lot.
