Once the package is installed, edit miniserv.conf file.

[root@node1 ~]# vim /etc/usermin/miniserv.conf 

Now add the below line in the end of that configuration file.

allow=127.0.0.1 192.168.5.141

Next start and enable the service for Usermin and allow the default port 20000 on firewall.

[root@node1 ~]# service usermin start
[root@node1 ~]# chkconfig usermin on
[root@node1 ~]# firewall-cmd --permanent --add-port=20000/tcp
success
[root@node1 ~]# firewall-cmd --reload
success

Once all the necessary steps are done for installing Usermin, we can open the web browser and call https://192.168.5.141:20000 to access Usermin control panel web user interface.

You need to replace with your ip address on that link.
