Using Webmin to Manage Network Services on CentOS 7

Webmins can be used  to configure operating system internals, such as users, disk quotas, services or configuration files, as well as modify and control open source apps, such as the Apache HTTP Server, PHP or MySQL

Webmin is largely based on Perl, running as its own process and web server. It is built around modules, which have an interface to the configuration files and the Webmin server. This makes it easy to add new functionality. Due to Webmin’s modular design, it is possible for anyone to write plugins for desktop configuration. Webmin also allows for controlling many machines through a single interface, or seamless login on other webmin hosts on the same subnet or LAN. Webmin is a web based tool for Linux and helps manage the services like DNS, DHCP, MySQL server, PostgreSQL and other networking services. It also helps to manage the user, disk, bandwidth monitoring, file system, process, packages, etc..

Step 1: First download Webmin by running the following command on the terminal.
Step 2:Now run the command to install downloaded Webmin rpm package.
Step 3: Use the following command to start Webmin services.
Step 4: Auto start Webmin at system startup.
Step 5: Webmin listens on port no. 10000, so allow this port on the firewall.
Step 6: Now open up a browser and visit http://your-ip-address:10000, you will be asked to enter username and password. Use root username and password of your OS root user account.

Step 7: After you have logged in, you get the dashboard where you get all information of your server and lots of options in the left side panel. Here you can do specific tasks like manage user accounts, Apache, DNS, file sharing, bandwidth monitoring and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
