Without limits, one site using an unfair share (because of a DDoS attack, a badly written script or a traffic spike) can slow down or crash the whole server and every site on it. Finding the culprit takes time and often means suspending accounts.<\/p>\n<h2>How CloudLinux solves it<\/h2>\n<p>CloudLinux places each account in its own LVE (LightWeight Virtual Environment) with a set amount of resources. If a site reaches its limits, only that site is affected, and the other sites on the same server keep working normally.<\/p>\n<h2>What CloudLinux limits<\/h2>\n<ul>\n<li><strong>CPU<\/strong> usage<\/li>\n<li><strong>RAM<\/strong> (physical memory)<\/li>\n<li><strong>I\/O<\/strong>: disk read and write speed<\/li>\n<li><strong>Entry processes<\/strong>: simultaneous connections to PHP<\/li>\n<li><strong>Inodes<\/strong>: the number of files<\/li>\n<\/ul>\n<h2>Security with CageFS<\/h2>\n<p>CageFS isolates each user so they can&#8217;t see or access other users&#8217; files, and system files are read-only, which makes shared hosting much safer.<\/p>\n<h2>CloudLinux features<\/h2>\n<ol>\n<li><strong>Dedicated resources per customer:<\/strong> each account gets its own guaranteed CPU and memory.\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-9784\" src=\"https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/LVM.png\" alt=\"\u0645\u0627\u0647\u0648 \u0643\u0644\u0627\u0648\u062f \u0644\u064a\u0646\u0643\u0633 cloudlinux \u061f\" width=\"801\" height=\"353\" title=\"\" srcset=\"https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/LVM.png 1024w, https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/LVM-300x132.png 300w, https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/LVM-768x339.png 768w\" sizes=\"(max-width: 801px) 100vw, 801px\"><\/p>\n<\/li>\n<li><strong>Stable hosting:<\/strong> traffic spikes on other sites don&#8217;t take yours down.<\/li>\n<li><strong>Hardened kernel:<\/strong> helps stop malicious users from attacking other accounts on the server.<\/li>\n<li><strong>Multiple PHP versions:<\/strong> the PHP Selector lets each customer choose their PHP version and extensions and adjust PHP settings.\n<p><img decoding=\"async\" class=\"alignnone wp-image-9788\" src=\"https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/phpselector-screen-php-version-cpanel-cloudlinux.png\" alt=\"\" width=\"768\" height=\"371\" title=\"\" srcset=\"https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/phpselector-screen-php-version-cpanel-cloudlinux.png 1024w, https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/phpselector-screen-php-version-cpanel-cloudlinux-300x145.png 300w, https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/phpselector-screen-php-version-cpanel-cloudlinux-768x371.png 768w, https:\/\/www.hyyat.com\/zasogooh\/2019\/02\/phpselector-screen-php-version-cpanel-cloudlinux-360x174.png 360w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/p>\n<\/li>\n<li><strong>Stable MySQL:<\/strong> MySQL Governor tracks each account&#8217;s database usage in real time and throttles heavy queries within its limits.<\/li>\n<\/ol>\n<p><strong>Note:<\/strong> CloudLinux is a paid system, and all Hyyat Host hosting servers run it.<\/p>\n<p>Related service: <a href=\"https:\/\/www.hyyat.com\/en\/shared-hosting-2\/\">cPanel shared hosting on CloudLinux<\/a> from Hyyat Host, with 24\/7 support.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In short: CloudLinux is an operating system for shared hosting servers that puts every account in its own lightweight virtual environment (LVE) with fixed limits on CPU, RAM, disk I\/O, processes and files.
