Webmin is an open source interface for Unix system administration that offers an easy to use graphical interface for managing user accounts, DNS, file sharing, and more. Webmin alleviates the need to use the command line to edit Unix system configuration files and allows you to configure your system easily from a simple web interface.
Deploy Webmin with Marketplace Apps
Linode’s App Marketplace allows you to easily deploy software on a Linode using the Linode Cloud Manager. To access Linode’s App Marketplace:
Log in to your Linode Cloud Manager account.
From the Linode dashboard, click on the Marketplace button in the left-hand navigation menu.
The Linode creation page appears, with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy:
Once you have selected the app, proceed to the app’s Options section and provide values for the required fields.
The Webmin Marketplace form includes advanced fields to setup your Webmin’s limited user account and DNS records. These are optional configuration options and are not required for installation.
|The limited sudo user to be created for the Linode||This is the limited user account to be created for the Linode. This account will have sudo user privileges.|
|The password for the limited sudo user||Set a password for the limited sudo user. The password must meet the complexity strength validation requirements for a strong password. This password can be used to perform any action on your server, similar to root, so make it long, complex, and unique.|
|The SSH Public Key that will be used to access the Linode||If you wish to access SSH via Public Key (recommended) rather than by password, enter the public key here.|
|Enable passwordless sudo access for the limited user?||If you entered an SSH Public Key above and it is for the limited user account, select |
|Disable root access over SSH?||Select |
|Configure automatic security updates||Select |
|Use fail2ban to prevent automated intrusion attempts||Select |
|Your Linode API Token||Your Linode |
|Subdomain||The subdomain you wish the installer to create a DNS record for during setup. The suggestion given is |
|Domain||The domain name where you wish to host your Webmin server. The installer creates a DNS record for this domain during setup if you provide this field along with the required |
|Admin Email for the server||The start of authority (SOA) email address for this server. This email address will be added to the SOA record for the domain. This is a required field if you want the installer to create DNS records.|
|Do you need an MX record for this domain?||Check |
|Do you need an SPF record for this domain?||Check |
After providing the app-specific options, provide configurations for your Linode server:
|Select an Image||Debian 10 is currently the only image supported by the Webmin Marketplace App, and it is pre-selected on the Linode creation page. Required|
|Region||The region where you would like your Linode to reside. In general, it’s best to choose the location that’s closest to you. For more information on choosing a data center, review the How to Choose a Data Center guide. You can also generate MTR reports for a deeper look at the network routes between you and each of our data centers. Required.|
|Linode Plan||Your Linode’s hardware resources. You can use any size Linode for your Webmin App as it uses minimal system resources. The minimum recommended memory is 1 GB and the minimum recommended free disk space is 1 GB. You can always resize your Linode to a different plan later if you feel you need to increase or decrease your system resources. Required|
|Linode Label||The name for your Linode, which must be unique between all of the Linodes on your account. This name will be how you identify your server in the Cloud Manager’s Dashboard. Required.|
|Add Tags||A tag to help organize and group your Linode resources. Tags can be applied to Linodes, Block Storage Volumes, NodeBalancers, and Domains.|
|Root Password||The primary administrative password for your Linode instance. This password must be provided when you log in to your Linode via SSH. The password must meet the complexity strength validation requirements for a strong password. Your root password can be used to perform any action on your server, so make it long, complex, and unique. Required|
When you’ve provided all required Linode Options, click on the Create button. Your Webmin app will complete installation anywhere between 2-5 minutes after your Linode has finished provisioning.
Getting Started after Deployment
Webmin is now installed and ready to use.
If you filled out the optional Webmin configuration fields:
Webmin is served on port 10000. To access Webmin, navigate to either the IP address of your server, or to your domain name followed by port 10000. For example, entering
http://203.0.113.0:10000while replacing the domain name or IP address with values for your server will allow you to reach the Webmin login screen.
At the login screen, login using either:
- The system root username and password
- The sudo username and password if you set that up in the Webmin optional configuration during installation.
Once logged in, you will be taken to the Webmin dashboard, where you can see various statistics and controls for your server.
NoteCurrently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
