No, Webmin is a separate install, but a good tool to have in addition to Kloxo-MR.
Here is the procedure to install:
Create a text file with following content (use cut and past):
[Webmin]
name=Webmin Distribution Neutral
#baseurl=http://download.webmin.com/download/yum
mirrorlist=http://download.webmin.com/download/yum/mirrorlist
enabled=1
Save the file as webmin.repo to your computer, then use Filezilla to move it over to your server into the /etc/yum.repos.d folder.
Now install the GPG key with which the packages are signed, with the following commands in SSH:
# cd /tmp
# wget
http://www.webmin.com/jcameron-key.asc# rpm --import jcameron-key.asc
# yum install webmin
# cd /
Start webmin and also auto start webmin at system startup:
# /etc/init.d/webmin start
# chkconfig webmin on
Now, in your browser type your server IP address at port 10000 and webmin should start.
Hope this helps
