It is stable software with a high level of security and various panel options.<br>\n<\/p><\/div>\n\n\n\n<\/p><p>From small businesses to high-end corporate IT applications, many projects use CentOS because of its stability, high security, and numerous control panel options. Aside from that, CentOS has a growing community that contributes to developing the Linux distro by creating wiki content, giving technical support, and finding bug fixes.<\/p><p>In this article, we will describe CentOS and its key features. We will also discuss the differences between CentOS Linux, CentOS Stream, and Red Hat Enterprise Linux.<\/p><h2 class=\"wp-block-heading\" id=\"h-centos-linux-distribution-key-features\">CentOS Linux Distribution Key Features<\/h2><p>Compared to other Linux-based operating systems, CentOS has some distinctive features such as:<\/p><ul class=\"wp-block-list\">\n<li><a href=\"\/ca\/tutorials\/how-to-install-ssl-certificate-on-centos-7\/\"><strong>Great security features<\/strong><\/a><strong>.<\/strong> CentOS complements its security architecture with the <a href=\"\/ca\/tutorials\/what-is-selinux\/\">Security-Enhanced Linux (SELinux)<\/a> system. It provides access control policies that you can enable for various processes and files.<\/li>\n\n\n\n<li><strong>Regular updates.<\/strong> Red Hat releases a new major CentOS Linux version every few years, and each is supported for ten years. This results in less issues which may be caused by updating the software.<\/li>\n\n\n\n<li><strong>Stability. <\/strong>CentOS uses stable software versions since the release cycle is longer. Therefore, applications don&rsquo;t need to be updated as often.<\/li>\n\n\n\n<li><strong>Panel options.<\/strong> CentOS users have various options of management platforms, including cPanel, Plesk, WebMin, Spacewalk, CWP, Virtualmin, and VestaCP.<\/li>\n\n\n\n<li><strong>Free of charge.<\/strong> CentOS is an open-source distribution. This means that users may modify and distribute it freely.<\/li>\n<\/ul><p>CentOS is one of the OS templates available with our VPS plans. You can select it during your initial VPS setup or switch to it anytime later. Explore our <a href=\"\/ca\/vps\/centos-hosting\">CentOS hosting plans<\/a> for more details.<\/p><h2 class=\"wp-block-heading\" id=\"h-centos-linux-vs-centos-stream\">CentOS Linux vs CentOS Stream<\/h2><p>The CentOS project is responsible for two Linux distributions &ndash; CentOS Linux and CentOS Stream. The former is a downstream rebuild of Red Hat Enterprise Linux (RHEL). In comparison, CentOS Stream is the upstream version as it serves as a platform for upcoming RHEL releases.<\/p><p>Before changes are applied to CentOS Linux, they are first submitted to the upstream projects included in the distribution, such as Fedora. That is why it takes years before a major update is released publicly. As for CentOS Stream, users contribute directly to its official repository. This cuts the release cycle down to weeks or days.<\/p><p>A new major CentOS Linux version usually consists of a large batch of updates, with smaller improvements in-between releases. On the other hand, each CentOS Stream revision includes any upcoming minor RHEL updates.<\/p><p>However, the CentOS project has decided to discontinue CentOS Linux. Users can migrate their systems to a different path like&nbsp;<a href=\"https:\/\/www.centos.org\/centos-stream\" target=\"_blank\" rel=\"noreferrer noopener\">CentOS Stream<\/a>. The CentOS community will continue collaborating on other open-source Linux distributions as part of the CentOS Stream project. If you choose Hostinger VPS hosting, you will get the CentOS 9 Stream version.<\/p><h2 class=\"wp-block-heading\" id=\"h-centos-linux-vs-red-hat-enterprise-linux\">CentOS Linux vs Red Hat Enterprise Linux<\/h2><p>Red Hat Enterprise Linux was released in 2000 by Red Hat. It is derived from the Fedora project. In 2014, Red Hat announced it would sponsor CentOS. Consequently, the CentOS Governing Board was formed, consisting of Red Hat members to assist and guide the software development. However, the CentOS team has remained independent from RHEL by removing Red Hat branding and artwork.<\/p><p>CentOS Linux is open-source software, which means that all its code and programs are available for people to use, modify, and distribute. In comparison, RHEL is built on open-source components but a user has to purchase a license in order to use it for commercial applications. In addition, Red Hat has implemented the Red Hat Developer Subscription for Individuals program, making the distro free to download but only for small production workloads.<\/p><p>When it comes to assistance, CentOS provides community forums where users answer each others&rsquo; questions &ndash; there is no dedicated customer support. However, CentOS Linux users can reach out for third-party support for a fee. The same goes for RHEL, although users have the option to upgrade their plan to include customer support.<\/p><p>In terms of software updates, they are implemented on RHEL first and later deployed to CentOS Linux. Therefore, both of them include the same functionality, compatibility, and bug fixes. Moreover, the same applications and add-on software like <a href=\"\/ca\/tutorials\/vps\/how-to-install-lamp-stack-centos7\/\">LAMP<\/a> and <a href=\"\/ca\/tutorials\/what-is-docker\/\">Docker<\/a> are usually available on both CentOS Linux and RHEL.<\/p><p>        <div class=\"protip\">\n            <div class=\"protip__heading\">\n                <svg width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n                    <path d=\"M1.49234 23.5024C1.23229 23.5024 0.972242 23.4024 0.782206 23.2123C0.562165 22.9923 0.452144 22.6822 0.502153 22.3722C0.562165 21.9221 1.14227 17.9113 3.00262 16.351C3.63274 15.8209 4.43289 15.5509 5.26305 15.5609C6.09321 15.5909 6.87335 15.9109 7.47347 16.4911C8.6937 17.6913 8.76371 19.6717 7.6435 20.9919C6.0832 22.8523 2.08245 23.4324 1.63237 23.4924C1.59236 23.4924 1.54235 23.4924 1.50234 23.4924L1.49234 23.5024ZM5.16303 17.5613C4.84297 17.5613 4.53291 17.6713 4.29287 17.8813C3.60274 18.4614 3.07264 19.9317 2.75258 21.242C4.06282 20.9219 5.5331 20.3918 6.11321 19.7017C6.55329 19.1716 6.54329 18.3814 6.0832 17.9213C5.85316 17.7013 5.5431 17.5713 5.20304 17.5613C5.19304 17.5613 5.17303 17.5613 5.16303 17.5613ZM11.7243 21.8821C11.4942 21.8821 11.2642 21.8021 11.0841 21.652C10.8541 21.462 10.7241 21.1819 10.7241 20.8819V15.9109L8.08358 13.2705H3.11264C2.81259 13.2705 2.53254 13.1404 2.3425 12.9104C2.15246 12.6803 2.07245 12.3803 2.12246 12.0902C2.19247 11.7102 2.84259 8.36953 4.70294 7.12929C6.33325 6.04909 8.96375 6.49918 10.244 6.80923C11.5442 4.96889 13.2546 3.4286 15.2349 2.33839C17.4553 1.11816 19.9858 0.518051 22.4963 0.498047C23.0464 0.498047 23.4865 0.948132 23.4865 1.49824C23.4865 5.0389 22.3763 9.97983 17.1753 13.7605C17.4853 15.0408 17.9354 17.6613 16.8552 19.2816C15.615 21.1419 12.2744 21.7921 11.8943 21.8621C11.8343 21.8721 11.7743 21.8821 11.7143 21.8821H11.7243ZM12.7245 16.181V19.6016C13.7146 19.2916 14.7948 18.7915 15.2049 18.1814C15.675 17.4812 15.605 16.091 15.385 14.9008C14.5248 15.3808 13.6346 15.8109 12.7245 16.181ZM9.66388 12.0302L11.9643 14.3307C13.1845 13.8306 14.3648 13.2204 15.485 12.5103C19.9358 9.51974 21.2361 5.60901 21.4561 2.53843C19.6157 2.67846 17.8254 3.20856 16.2051 4.09872C14.2847 5.14892 12.6544 6.68921 11.4942 8.54956C10.7841 9.65977 10.174 10.82 9.66388 12.0302ZM4.39289 11.2701H7.81353C8.1936 10.3599 8.63368 9.46974 9.11377 8.60957C7.92355 8.38953 6.51329 8.31952 5.81315 8.78961C5.19304 9.19968 4.70294 10.3099 4.39289 11.2701Z\" fill=\"#673DE6\"\/>\n                <\/svg>\n                <p class=\"protip__title\">\n                    Learn More About CentOS                <\/p>\n            <\/div>\n            <p class=\"protip__content\"><a href=\"\/ca\/tutorials\/centos-vs-ubuntu\/\">CentOS vs Ubuntu<\/a><br>\n<a href=\"\/ca\/tutorials\/how-to-set-the-timezone-in-centos\/\">How to Set Timezone in CentOS<\/a><br>\n<a href=\"\/ca\/tutorials\/change-hostname-on-centos-7\/\">How to Change Hostname on CentOS<\/a><\/p>\n                    <\/div>\n        \n\n\n\n<\/p><h2 class=\"wp-block-heading\" id=\"h-conclusion\">Conclusion<\/h2><p>CentOS is one of the most popular Linux distributions. It is an open-source operating system that provides an enterprise-class computing platform. CentOS strives to maintain 100% binary compatibility with Red Hat Enterprise Linux. We&rsquo;ve discussed CentOS&rsquo;s five defining features &ndash; it&rsquo;s highly secure, regularly updated, stable, free of charge, and supports different control panels.<\/p><p>The CentOS project oversees two versions of the distro &ndash; CentOS Linux and CentOS Stream. The main difference between them is that the former is downstream of Red Hat Enterprise Linux while CentOS Stream is the upstream version containing upcoming minor Red Hat updates.<\/p><p>CentOS joined Red Hat in 2014 but has remained independent. While CentOS Linux is open-source software anyone can use, Red Hat Enterprise Linux offers a no-cost program only for individuals. However, users have the option to upgrade their plan for more advanced features.<\/p><p>We hope this article has helped you discover more about CentOS.
