Customizing the Portal Dedicated tmp location

Before changing the Portal tmp location, create the directory with appropriate permissions:

sudo mkdir -p /waratek/tmp

sudo chmod 755 /waratek/tmp

sudo chown <portal_user>: /waratek/tmp

Note: Replace <portal_user> with the user that runs the Portal service (check with sudo systemctl status portal).

Now you must edit the service script and make the following changes. Add the following to the ExecStart line in the Portal service script (location found by using sudo systemctl status portal)

-Djna.tmpdir=/waratek/tmp

Reload the systemctl daemon and restart the Portal service

sudo systemctl daemon-reload

sudo systemctl restart portal

Note: On SELinux if the Portal service fails to start after making these changes, SELinux may be blocking the service. Check the service status with sudo systemctl status portal. To temporarily disable SELinux for troubleshooting, run sudo setenforce 0. For production environments, configure SELinux policies appropriately to allow Portal startup with the custom tmp directory.
