CentOS is a Linux distribution based on Red Hat Enterprise Linux. Some of the main features of CentOS are:

  • Stable and reliable: CentOS follows a "stable release" model, releasing updates only when thoroughly tested. This makes it suitable for production use.

  • Free and open source: CentOS is based on Red Hat Linux and uses the same open-source components and licenses. It can be used and modified freely.

  • Enterprise-ready: CentOS provides a similar set of features and packages as Red Hat Enterprise Linux, making it suitable for enterprise use. It does not include commercial support, though.

  • Compatible with Red Hat: Since CentOS is almost identical to Red Hat Linux in terms of software and configuration, knowledge, tools, and applications developed for Red Hat Linux also work on CentOS.

  • Rich package repository: CentOS has extensive storage of software packages that can be installed using the Yum package manager. This includes typical server applications and development tools.

  • Command-line oriented: CentOS is primarily configured and administered from the command line, like most Linux distributions. This requires some technical knowledge of Linux.

  • Focus on stability: CentOS focuses on strength and reliability over bleeding edge features. Updates and newer versions of software packages are thoroughly tested before being made available.

    Some of the most popular programming languages used with CentOS are:

    1. Python - Python has rapidly grown in popularity for web and general-purpose programming. It is used for backend web development, data analysis, and scientific computing. CentOS has a rich set of Python libraries and tools available.

    2. PHP - PHP is the most popular language for web development, especially for creating dynamic websites and web applications. Many popular content management systems like WordPress, Drupal, and Joomla! are built with PHP.

    3. Perl is an older language but still widely used, especially for system administration tasks, server-side scripts, and web development. There are lots of Perl modules available in the CentOS repositories.

    4. Java - Java is an enterprise-level language famous for creating robust and scalable applications. CentOS includes the Oracle Java Development Kit to compile and run Java applications.

    5. Ruby - Ruby, and Ruby on Rails are popular frameworks for creating dynamic web applications. CentOS has all the required Ruby libraries and tools available.

    6. JavaScript - While primarily a client-side language, JavaScript is now used extensively on the server side and with the help of Node.js. CentOS includes Node.js packages so you can develop and run Node applications.

    7. C/C++ - C and C++ are relevant for developing low-level applications, drivers, daemons, and embedded software. The GNU Compiler Collection (GCC) is available in CentOS to compile C/C++ applications.
