How to install WebMin in CentOS 7

How to install WebMin in CentOS 7.

First Download the CentOS 7 minimal ISO (https://www.centos.org/download/)

Create a VM in VirtualBox
Name: CentOS - WebMin
Type: Linux
Version: Red Hat (64-bit)

Attach the downloaded CentOS 7 ISO after creating the VM
Make sure enable 'Adapter 2' and attach to 'Host-Only'
Start the VM and complete the installation with default options.

Once installation is completed , execute below commands

Change Host Name

hostnamectl set-hostname webmin01.mylinxlabs.com --static --transient

Delete the dhcp configuration of enp0s8 and re-create it with static IP
(use the 'ip a' command to see the interface name)

nmcli con del enp0s8
nmcli con add type ethernet con-name enp0s8 ifname enp0s8 ip4 192.168.56.10/24

Add hostname to /etc/hosts
cat EOF /etc/hosts
192.168.56.10 webmin01.mylinxlabs.com webmin01
EOF
Now you can access the VM via SSH using the IP which set above (192.168.56.10)
Make sure the NAT interface is up. If not then execute below commands

ifup enp0s3
nmcli con mod enp0s3 connection.autoconnect yes

Configure YUM repo for WebMin

cat EOF /etc/yum.repos.d/webmin.repo
[WebMin]
name="Webmin Distribution Neutral"
mirrorlist=http://download.webmin.com/download/y...
enabled=1
EOF

curl http://www.webmin.com/jcameron-key.asc -O
rpm --import jcameron-key.asc

Now install below packages

yum install webmin

Open 10000 port which will be used by WebMin
firewall-cmd --zone=public --add-port=10000/tcp --permanent
firewall-cmd --reload

Make sure WebMin is running
/etc/init.d/webmin status

Now you can access the WebMin interface using URL https://192.168.56.10:10000
