Enable and Configure http to https redirection for Apache on CentOS 7

Method 1

• Create .htaccess file under the root of the web folder

         RewriteEngine On RewriteCond %{SERVER_PORT} 80 RewriteCond %{HTTP_HOST} ^(www\.)?coolexample\.com RewriteRule ^(.*)$ https://www.coolexample.com/$1 [R,L]

where www.coolexample.com should change to the url of the website

• Check the line LoadModule rewrite_module modules/mod_rewrite.so in /etc/httpd/conf.modules.d/00-base.conf is not comment or missing. If it is commented or missed, the mod_rewrite of Apache is not enabled. 

• Edit the /etc/httpd/conf/httpd.conf to allow override

          <Directory /var/www/html>

     AllowOverride All
</Directory>

       

• Restart the Apache to put the change into effect 

Method 2

• vi /etc/httpd/conf.d/ssl.conf
• Add following

      <VirtualHost *:80>

                ServerAdmin webmaster@your domain name

                DocumentRoot /var/www/html/your folder root

                ServerName your server name

                RewriteEngine on

               RewriteRule ^(.*) https://your domain name$1 [R=301,L]

     </VirtualHost>
