Guides to web administration Interface (webmin, Virtualmin)

# Installing web administration interface

the os used is ubuntu 20.4 ( server edition)

1. update the repositories

sudo apt update

2. the upgrade is optional 3. install the properties repo

sudo apt install software-properties-common apt-transport-https wget

4. Add the repositories source in the source.list the command for that is

sudo nano /etc/apt/sources.list
# Add these lines at last
deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge
contrib
# Save and exit the editor

5. Install the GPG key to trust the repositories the command is

wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -

6. update the repositories list

sudo apt update

7. Install the webmin

sudo apt install webmin

8. If the firewall is enabled we can allow port 10000 as this is the default port for webmin since ubuntu uses UFW we can use following command

9. now we can visit the URL after completion of install

https://<IP>:10000/

Installing the plugin(virtualmin) for better management.

1. Download the shell script

curl -O http://software.virtualmin.com/gpl/scripts/install.sh

2. make the script executable

sudo chmod +x install.sh
sudo ufw allow 10000
sudo ufw reload

3. Run the command

sudo ./install.sh
sudo apt install apache2
/etc/init.d/apache2 stop ; update-rc.d apache2 remove

this will stop the apache as well

# Installing webservers

since apache2 is preinstalled if not we can install it with

sudo apt install apache2

we can directly go of the installation of nginx

1. Shut down Apache with the command `service httpd stop ; chkconfig httpd off` (on RHEL or CentOS), or (on Debian).

/etc/init.d/apache2 stop ; update-rc.d apache2

2. Install Nginx with the command `yum install nginx` (on RHEL or CentOS) or `apt-get install nginx` (on Debian).
3. Start the Nginx webserver with the command

/etc/init.d/nginx start

4. Install Virtualmin’s Nginx plugin with the command `yum install wbm-virtualmin-nginx wbm- virtualmin-nginx-ssl` (on RHEL or CentOS) or `apt-get install webmin-virtualmin-nginx webmin- virtualmin-nginx-ssl` (on Debian).

configure nginx to run on any port

1. change the default configuration

vi /etc/nginx/sites-enabled/default

2. change the nginx port no

server {
        listen 8080 default_server;
listen [::]:8080 default_server;
        ...
