Easy way to install webmin on CentOS 4

Webmin is a web based control panel for system administrators for Unix/Linux. I use Webmin for reports mainly. More about Webmin here.

This is how you would install Webmin on Centos 4.

1. First start by downloading the latest version of Webmin. The current version is 1.400.

I prefer to use use wget to directly download the file onto the server but it’s up to you.

wget http://prdownloads.sourceforge.net/webadmin/webmin-1.400-1.noarch.rpm

2. Install the Webmin rpm package.

rpm -ivh  webmin-1.400-1.noarch.rpm

[root@proxy0 /]# rpm -ivh webmin-1.400-1.noarch.rpm
warning: webmin-1.400-1.noarch.rpm: V3 DSA signature: NOKEY, key ID 11f63c51
Preparing...                ########################################### [100%]
Operating system is CentOS Linux
1:webmin                 ########################################### [100%]
Webmin install complete. You can now login to https://proxy0.klm1.netcel360.com:10000/
as root with your root password.

3. Check if the Webmin service has been started.

service webmin status

[root@proxy0 /]# service webmin status
webmin (pid 4878) is running

That’s it, you can now login using your root id at https://localhost:10000
