The following commands can be used to install Webmin 1.610 on CentOS 5.8. Make sure you’re logged in as root and then follow the steps below.
Select a temporary directory to save the download to. We will only use the downloaded file once so it’s pointless keeping it.. free up space and put it in /tmp!
cd /tmp
Begin the download of Webmin using wget:
wget http://prdownloads.sourceforge.net/webadmin/webmin-1.610-1.noarch.rpm
Install Webmin by unpacking the archive:
rpm -Uvh webmin-1.610-1.noarch.rpm
Done! You can now login to your fresh installation of Webmin by heading to http://hostname-or-ipaddress:10000 using the root username and password.
