It is very useful for dynamic websites that allow repeated PHP object calls to be cached in system memory. It stores data based on key-values for small arbitrary strings or objects. It offers a lot of features including, ease of use, sub-millisecond latency, multithreaded architecture, data partitioning, support for multiple languages, and many more.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>In this tutorial, we will show you how to install Memcached with Apache on an Ubuntu 20.04 VPS.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_65 counter-hierarchy ez-toc-counter ez-toc-transparent ez-toc-container-direction\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-662dfb61a0d47\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-662dfb61a0d47\"  aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Prerequisites\" title=\"Prerequisites\">Prerequisites<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Step-1-Log-in-to-the-Server-Update-the-Server-OS-Packages\" title=\"Step 1: Log in to the Server &amp; Update the Server OS Packages\">Step 1: Log in to the Server &amp; Update the Server OS Packages<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Step-2-Install-Memcached\" title=\"Step 2: Install Memcached\">Step 2: Install Memcached<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Step-3-Configure-Memcached\" title=\"Step 3: Configure Memcached\">Step 3: Configure Memcached<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Step-4-Install-and-Configure-Apache-with-Memcached-Support\" title=\"Step 4: Install and Configure Apache with Memcached Support\">Step 4: Install and Configure Apache with Memcached Support<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.rosehosting.com\/blog\/install-memcached-with-apache-on-ubuntu-20-04\/#Step-5-Verify-Memcached\" title=\"Step 5: Verify Memcached\">Step 5: Verify Memcached<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\" id=\"h-prerequisites\"><span class=\"ez-toc-section\" id=\"Prerequisites\"><\/span>Prerequisites<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul><li>An Ubuntu 20.04 VPS (we\u2019ll be using our SSD 2 VPS plan)<\/li><li>Access to the root user account (or access to an admin account with root privileges)<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-1-log-in-to-the-server-update-the-server-os-packages\"><span class=\"ez-toc-section\" id=\"Step-1-Log-in-to-the-Server-Update-the-Server-OS-Packages\"><\/span>Step 1: Log in to the Server &amp; Update the Server OS Packages<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>First, log in to your Ubuntu 20.04 server via SSH as the root user:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">ssh root@IP_Address -p Port_number<\/pre>\n\n\n\n<p>You will need to replace &#8216;IP_Address&#8217; and &#8216;Port_number&#8217; with your server&#8217;s respective IP address and SSH port number. Additionally, replace &#8216;root&#8217; with the username of the admin account if necessary.<\/p>\n\n\n\n<p>Before starting, you have to make sure that all Ubuntu OS packages installed on the server are up to date. You can do this by running the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get update -y\napt-get upgrade -y<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-2-install-memcached\"><span class=\"ez-toc-section\" id=\"Step-2-Install-Memcached\"><\/span>Step 2: Install Memcached<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The Memcached package is available in the Ubuntu 20.04 default OS repository. You can install it by running the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get install memcached libmemcached-tools -y<\/pre>\n\n\n\n<p>By default, the Memcached service will start automatically after installing it in your system. You can verify it with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl status memcached<\/pre>\n\n\n\n<p>You should get the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">\u25cf memcached.service - memcached daemon\n     Loaded: loaded (\/lib\/systemd\/system\/memcached.service; enabled; vendor preset&gt;\n     Active: active (running) since Fri 2021-01-08 08:25:36 UTC; 12s ago\n       Docs: man:memcached(1)\n   Main PID: 32022 (memcached)\n      Tasks: 10 (limit: 2353)\n     Memory: 1.5M\n     CGroup: \/system.slice\/memcached.service\n             \u2514\u250032022 \/usr\/bin\/memcached -m 64 -p 11211 -u memcache -l 127.0.0.1 -P&gt;\n\nJan 08 08:25:36 ubuntu2004 systemd[1]: Started memcached daemon.\n<\/pre>\n\n\n\n<p>You can also start and stop the Memcached service using the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl start memcached\nsystemctl stop memcached<\/pre>\n\n\n\n<p>Memcached listens on port 11211, you can also verify it using the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">ss -antpl | grep 11211<\/pre>\n\n\n\n<p>You should get the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">LISTEN  0        1024                    127.0.0.1:11211          0.0.0.0:*      users:((\"memcached\",pid=32022,fd=26))  \n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-3-configure-memcached\"><span class=\"ez-toc-section\" id=\"Step-3-Configure-Memcached\"><\/span>Step 3: Configure Memcached<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Memcached main configuration file is located at \/etc\/memcached.conf. By default, Memcached listens on localhost on port 11211. If your application is running on the remote host then you will need to configure Memcached to allow connection from the remote host.<\/p>\n\n\n\n<p>To do so, edit the \/etc\/memcached.conf:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">nano \/etc\/memcached.conf<\/pre>\n\n\n\n<p>Find the following line:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">-l 127.0.0.1\n<\/pre>\n\n\n\n<p>Replace it with your server IP as shown below:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">-l 192.168.0.100\n<\/pre>\n\n\n\n<p>Save and close the file then restart the Memcached service to apply the changes:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl restart memcached<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-4-install-and-configure-apache-with-memcached-support\"><span class=\"ez-toc-section\" id=\"Step-4-Install-and-Configure-Apache-with-Memcached-Support\"><\/span>Step 4: Install and Configure Apache with Memcached Support<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Next, you will need to install Apache and PHP, and enable Memcached support.
