Webmin is a web-based interface that allows Unix-like operating
systems and common Unix services to be easily administered.
Installing Webmin in /usr/local/webmin …
Webmin uses separate directories for configuration files and log files.
Unless you want to run multiple versions of Webmin at the same time
you can just accept the defaults.
Config file directory [/etc/webmin]:
Log file directory [/var/webmin]:
Webmin is written entirely in Perl. Please enter the full path to the
Perl 5 interpreter on your system.

Webmin uses its own password protected web server to provide access
to the administration programs. The setup script needs to know :
What port to run the web server on. There must not be another
web server already using this port.
The login name required to access the web server.
The password required to access the web server.
If the webserver should use SSL (if your system supports it).
Whether to start webmin at boot time.
Web server port (default 10000):
Login name (default admin):
Login password:
Password again:
Use SSL (y/n): y
Webmin does not support being started at boot time on your system.

Webmin has been installed and started successfully. Use your web
browser to go to
https://rhel8.local:10000/
and login with the name and password you entered previously.
Because Webmin uses SSL for encryption only, the certificate
it uses is not signed by one of the recognized CAs such as
Verisign. When you first connect to the Webmin server, your
browser will ask you if you want to accept the certificate
presented, as it does not recognize the CA. Say yes.Configure Webmin onRHEL 8|CentOS 8|Rocky Linux 8
To be able to access Webmin Web interface from the network, you need to allow TCP port 10000 in the firewall.
sudo firewall-cmd --add-port=10000/tcp --permanent
sudo firewall-cmd --reloadAccess Webmin Interface
Now that you have installed Webmin onRHEL 8|CentOS 8|Rocky Linux 8, open your server URL/IP address port 10000, e.g https://192.168.122.197:10000
If you get “Invalid Certificate” warning, click Continue Anyway
