In previous article, we already know about Webmin and Virtualmin. Webmin alone (without Virtualmin) suitable for system with small RAM, between 128 to 512 MB or 768 MB. I personally do not recommend using virtualmin for systems with less than 1 GB of RAM. This is because Virtualmin requires a fairly large memory.
It is assumed you already rent a VPS from a provider and use Ubuntu Server.
For your note, installing Webmin and Virtualmin should be done in the beginning. I mean, fresh install. After you rent the VPS and still not install anything. Because if there are lots of other programs installed, if error happened, it’s hard to check and repair them.
The first thing to do is login into the shell via SSH.
Then change the /etc/apt/sources.list file
$ joe /etc/apt/sources.list
(If you don’t have joe, please check the following article)
Add the following 2 lines at the bottom of that file
sarge contrib deb http://download.webmin.com/download/repository
http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib deb
Save by pressing Ctrl + K X
Install GPG Key with the following steps:
$ cd / root
$ wget http://www.webmin.com/jcameron-key.asc
$ apt-key add-key.asc jcameron
There will be jcameron-key.asc files in /root. This file is required for the installation process Webmin.
Install webmin with the following command:
$ apt-get update
$ apt-get install webmin
If asked:
After this operation, xx MB of additional disk space will be used.
Do you want to continue? [Y/n]
Just type Y and let the process run automatically.
Once completed, Webmin can be opened from a browser with address https://1.2.3.4:10000 (the port number is ten thousands, not a thousand). Change 1.2.3.4 with the IP addresses provided by the provider.
If this is your first time running Webmin at that VPS / dedicated server, you will see warning which tell you that website you access is not safe. The message varies depending on the browser.
For Firefox:
Click I Understand the Risks, then click Add Exception.
In the next confirmation box, click Confirm Security Exception.
For Opera:
Just click the Continue Anyway
Next, you will have to login to Webmin :
Make a login with the root user and use password given by the provider.
You’ve made it into Webmin. In the next article we will discuss what needs to be and can be done using Webmin.
Note:
When logged in into Webmin for the first time, you will notice that the website is not secure. But do not fear, because it is your own website, isn’t it?
Actually, the meaning of the warning because your website is not yet install the certificate. To install the certificate requires additional costs that are sometimes quite expensive, and less useful if only for your own use. Unless you are running an e-commerce website or any other website that requires the trust of others, you need certificate.
