How to Install Usermin on Ubuntu21

Usermin is a web-based interface mainly for webmail designed for non-root users to perform routine tasks including, reading mail, changing passwords, setting up databases and a web-based SSH terminal. It is a simpler version of Webmin for regular users without always system administrators.

It’s a version of Webmin that is for regular users without always system administrators. Usermin, like Webmin, is a basic web server and a set of CGI scripts that update user config files such as / .cshrc and / .forward. All CGI scripts and the web server are in Perl 5, and use only the non-standard Authen::PAM perl module.

It provides a rich set of features, some of them are as follows:

  • Create and manage the database.
  • Schedule emails.
  • Scheduling cron jobs.
  • Change files and folders permissions.
  • Secure web directories.
  • Using MySQL Database Server to configure MySQL database server’s databases, tables, and permissions.

Before starting, update the APT cache to the latest version. You can update it by running the following command:

apt-get -y update

Now, Run the following command to install all the dependencies:

apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl -y

By default, the Usermin package is not present in the Ubuntu default repository. So you will need to download the Usermin .deb package from the Usermin download page.

Use the following command to download Usermin.
