Let&#8217;s Encrypt is a completely free and automated, new certificate authority developed by the Internet Security Research Group (ISRG) and recognized by all major browsers. They make it a breeze to set up TLS certificates for your web server. And for free! Let&#8217;s Encrypt is supported by major players like Mozilla, Akamai, Cisco, the EFF and managed by the Linux Foundation. Let&#8217;s Encrypt provides free, automatic and secure certificates. The website owners can easily obtain security certificates within minutes, enabling a safer web experience for all.In today&#8217;s tutorial we are going to learn how to install a Let&#8217;s Encrypt SSL certificate on CentOS 7 with Apache, and configure the certbot for automatic renewal.<br \/>\n<!--more--><\/p>\n<h2>1. Update the system<\/h2>\n<p>As usual make sure the system is fully up to date before installing any packages:<\/p>\n<pre># yum -y update<\/pre>\n<h2>2. Install Apache<\/h2>\n<p>We are going to use Apache as our web server, install it using this command:<\/p>\n<pre># yum -y install httpd<\/pre>\n<h2>3.\u00a0Install mod_ssl<\/h2>\n<p>Install mod_ssl as well as we are going to need it to configure our Let&#8217;s Encrypt SSL certificate:<\/p>\n<pre># yum -y install mod_ssl<\/pre>\n<h2>4. Configure Apache<\/h2>\n<p>Create a document root folder for your site:<\/p>\n<pre># mkdir \/var\/www\/test<\/pre>\n<p>Create a virtual host config file for your site by opening it with nano and then pasting the following contents inside:<\/p>\n<pre># nano \/etc\/httpd\/conf.d\/test-site.conf\r\n\r\n&lt;VirtualHost *:80&gt;\r\n    ServerAdmin admin@test.com\r\n    DocumentRoot \"\/var\/www\/test\"\r\n    ServerName test.com\r\n    ServerAlias www.test.com\r\n    ErrorLog \"\/var\/log\/httpd\/test.error_log\"\r\n    CustomLog \"\/var\/log\/httpd\/test.access_log\" common\r\n&lt;\/VirtualHost&gt;\r\n<\/pre>\n<p>Add a index.html file for testing purposes later with the following contents:<\/p>\n<pre># nano \/var\/www\/test\/index.html\r\n\r\nIt works!\r\n<\/pre>\n<p>Change owner of the &#8220;\/var\/www\/test&#8221; directory to the apache user so Apache can read the directory:<\/p>\n<pre># chown -R apache:apache \/var\/www\/test<\/pre>\n<p>Remember to change &#8220;test&#8221; for your site&#8217;s name.<br \/>\nNow that we have Apache installed we can continue by installing certbot.<\/p>\n<h2>5. Install certbot<\/h2>\n<p>To install certbot first we need to make sure we have the EPEL repository enabled, to do that execute the following command:<\/p>\n<pre># yum -y install epel-release<\/pre>\n<p>Make sure yum-utils is installed:<\/p>\n<pre># yum -y install yum-utils<\/pre>\n<p>Then install certbot for Apache:<\/p>\n<pre># yum -y install certbot-apache<\/pre>\n<p>Now that we have certbot installed, run certbot with the following command:<\/p>\n<pre># certbot --apache<\/pre>\n<p>Certbot will ask you for the names you would like to activate HTTPS for:<\/p>\n<pre>Saving debug log to \/var\/log\/letsencrypt\/letsencrypt.log\r\nPlugins selected: Authenticator apache, Installer apache\r\nStarting new HTTPS connection (1): acme-v01.api.letsencrypt.org\r\n\r\nWhich names would you like to activate HTTPS for?\r\n-------------------------------------------------------------------------------\r\n1: test.com\r\n2: www.test.com\r\n-------------------------------------------------------------------------------\r\nSelect the appropriate numbers separated by commas and\/or spaces, or leave input\r\nblank to select all options shown (Enter 'c' to cancel):\r\n<\/pre>\n<p>Press enter to continue and then optionally if you want you can redirect your sites to HTTPS:<\/p>\n<pre>Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.\r\n-------------------------------------------------------------------------------\r\n1: No redirect - Make no further changes to the webserver configuration.\r\n2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for\r\nnew sites, or if you're confident your site works on HTTPS. You can undo this\r\nchange by editing your web server's configuration.\r\n-------------------------------------------------------------------------------\r\nSelect the appropriate number [1-2] then [enter] (press 'c' to cancel):\r\n<\/pre>\n<p>If everything goes well you should see the following output:<\/p>\n<pre>-------------------------------------------------------------------------------\r\nCongratulations! You have successfully enabled\r\nhttps:\/\/test.com and https:\/\/www.test.com\r\n\r\nYou should test your configuration at:\r\nhttps:\/\/www.ssllabs.com\/ssltest\/analyze.html?d=test.com\r\nhttps:\/\/www.ssllabs.com\/ssltest\/analyze.html?d=www.test.com\r\n-------------------------------------------------------------------------------\r\n<\/pre>\n<h2>6. Configure automatic renewal<\/h2>\n<p>Now we are going to add a cronjob so our Let&#8217;s Encrypt SSL certificates can be renewed automatically.<\/p>\n<p>First run the following command so we can have nano as the default editor:<\/p>\n<pre># export EDITOR=\/bin\/nano<\/pre>\n<p>Then execute the following command to edit the crontab:<\/p>\n<pre># crontab -e<\/pre>\n<p>Let&#8217;s Encrypt recommends the automatic renew cronjob to run twice a day, to do that add the following line and then save and exit the crontab:<\/p>\n<pre>* *\/12 * * * \/usr\/bin\/certbot renew &gt;\/dev\/null 2&gt;&amp;1<\/pre>\n<p>Now you should have successfully installed and configured Let&#8217;s Encrypt with Apache.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-431\" src=\"https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/01\/install-Let\u2019s-Encrypt-on-CentOS-7-with-Apache.jpg\" alt=\"install Let\u2019s Encrypt on CentOS 7 with Apache\" width=\"600\" height=\"121\" srcset=\"https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/01\/install-Let\u2019s-Encrypt-on-CentOS-7-with-Apache.jpg 600w, https:\/\/linuxhostsupport.com\/blog\/wp-content\/uploads\/2018\/01\/install-Let\u2019s-Encrypt-on-CentOS-7-with-Apache-300x61.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>Of course you don\u2019t have to install Let&#8217;s Encrypt on CentOS 7 with Apache, if you use one of our <a href=\"https:\/\/linuxhostsupport.com\/per-incident-support.html\">outsourced Linux server support services<\/a>, in which case you can simply ask our expert Linux admins to install Let&#8217;s Encrypt SSL certificate on your server with Apache.
