What is Webmin?
Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
“install from RPM” VS “install from repository”
When installing from RPM by “rpm -U webmin-1.470-1.noarch.rpm” you will not be able to upgrade Webmin by simple yum upgrade. To upgrade such installation you will need to redownload and reinstall RPM manually. E.g. no automatic upgrades are done.
When Webmin is installed from a repository, bug fixes and security patches can be automated as are other system updates, and managed using yum.. Also, yum_updatesd daemon will warn you about updates and/or install them depending on it’s settings.
How to install from repository
Become root.
Copy and paste the following into console:
(echo "[Webmin] name=Webmin Distribution Neutral baseurl=http://download.webmin.com/download/yum enabled=1" >/etc/yum.repos.d/webmin.repo rpm --import http://www.webmin.com/jcameron-key.asc yum -y install webmin)
Press enter if command hasn’t executed automatically.
Ok.
The Webmin repo and application are now installed.
