sudo systemctl restart usermin

Step 6 : Run the Usermin setup script to configure it according to your preferences:

sudo /usr/libexec/usermin/setup.sh

Step 7 : If you are using a firewall, you need to allow traffic on Usermin's default port (20000):

sudo firewall-cmd --permanent --add-port=20000/tcp
sudo firewall-cmd --reload

Step 8 : Verify that the Usermin service is running:

sudo systemctl status usermin
