As of <a href=\"https:\/\/news.cpanel.com\/easyapache-4-feb-6-release\/\">last week&#8217;s update<\/a>, EasyApache 4 includes a light version of mod_lsapi, a module built and distributed by our friends at CloudLinux. This release is a scaled-back version of the module already distributed by CloudLinux. Anyone already using CloudLinux should use the one distributed by CloudLinux, but for everyone else let&#8217;s talk about it!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is mod_lsapi?<br><\/h2>\n\n\n\n<p>mod_lsapi is an Apache module based on the&nbsp;<a href=\"https:\/\/www.litespeedtech.com\/open-source\/litespeed-sapi\">LiteSpeed Technologies API<\/a>&nbsp;that provides significant improvements in speed and resource use for PHP websites. The version that we are distributing allows cPanel &amp; WHM servers the option of using mod_lsapi on operating systems other than CloudLinux, and without LiteSpeed.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">cPanel&#8217;s LSAPI<\/h2>\n\n\n\n<p>The two main features of lsapi that are disabled in the cPanel-distributed version of mod_lsapi are <a href=\"https:\/\/docs.cloudlinux.com\/criu_support.html\">CRIU<\/a> (which requires kernel changes to enable), and connection pooling. A detailed understanding of the full-featured version of LSAPI can be found in&nbsp;<a href=\"https:\/\/docs.cloudlinux.com\/apache_mod_lsapi.html\">CloudLinux&#8217;s documentation<\/a>.&nbsp;To take advantages of the full benefits, you can upgrade from CentOS to CloudLinux via the promotional banner in the EasyApache or MultiPHP interfaces (only available on cPanel &amp; WHM Version 78 or higher).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why you might want to use mod_lsapi<\/h2>\n\n\n\n<p>LSAPI will give you a pretty significant boost all on its own, over mod_php. It can also be a replacement for PHP-FPM and can provide easier management for servers owners that don&#8217;t require much in-depth configuration. If you are using CentOS now and are considering upgrading to CloudLinux, you can get an extra 10% performance boost with that switch and enabling those two missing features.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Getting started<\/h2>\n\n\n\n<p>If you&#8217;re ready to install it, log in to WHM. After you navigate to the EasyApache 4 interface, edit your current profile and click on <em>Apache Modules<\/em>. In the search box enter <em><g class=\"gr_ gr_6 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling\" id=\"6\" data-gr-id=\"6\">lsapi<\/g><\/em> and you will see the module listed. Toggle the slider next to the module to enable it in your profile.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/blog.cpanel.com\/wp-content\/uploads\/2019\/02\/2019-02-11_1414.png\" alt=\"locating the lsapi module.\" class=\"wp-image-51761\"\/><\/figure>\n\n\n\n<p>Once you review any warnings presented, click <em>Review<\/em> on the left, and then select <em>Provision<\/em>. That&#8217;s it! <\/p>\n\n\n\n<p>For support with this module or anything else cPanel, always feel free to open up a ticket with our <a href=\"https:\/\/tickets.cpanel.net\">amazing support team<\/a>.
