How to redirect http to https on Apache2

Redirect HTTP To HTTPS

This is my favorite snippet code in Apche2 for redirect http protocol to https protocol. There are only two steps for completed this.

Step 1: Enable a2enmod rewrite

Assume, you are in terminal of server and logged as root permission

$ a2enmod rewrite

Step 2: Update sites-available conf file

Assume that my site conf file is default-ssl.conf, you can change to your actual conf file of sites-available.

$ nano /etc/apache2/sites-available/default-ssl.conf

Copy this code to the last of files

     RewriteEngine On
     RewriteCond %{HTTPS} off [OR]
     RewriteCond %{HTTP_HOST} ^www\. [NC]
     RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
     RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=301]

Than save files and restart service apache2.

$ sudo service apache2 restart
