Improve multinode setup

    XMLWordPrintable

    Details

      Description

      The multinode setup procedure should be enhanced the following way to make it as simple as possible and without forcing the user to modify files manually.

      As a user, I would like to setup a multinode system through the CLI or WebUI without modifying PostgreSQL configuration files and starting/stopping/restarting services manually. Thus I would expect something like that:

      On the master system:

      • Execute oaconfig --masternode install
      • The following information is requested via user input:
        • The IP address of the remote system
      • An OTP (one time password) will be generated and displayed which is used to authenticate incoming REST-API requests from the remote system to be connected.

      On the remote system:

      • Execute oaconfig --remotenode install
      • The following information is requested via user input:
        • The IP address of the master system
        • The OTP used to connect the remote to the master system

      With this information the system should be able to automatically setup and configure a multinode setup. Using the OTP, the remote system can get all required information (e.g. the database password) from the master and trigger REST-API calls on that system.

      It must be ensured that the master configuration is not overwritten when multiple remote systems are added. This must be asked explicitely when a remote system is added.
