+
+## Step 1: Upgrade Apache from PPA
+
+Let’s assume you installed Apache from the standard stable Ubuntu repository using apt. When you check your version of apache2 by typing:
+
+      apache2 -v
+
+… You’ll notice that Apache **2.4.18** is the current default version for Ubuntu 16.04. However, you need Apache 2.4.24 or later for compatibility with HTTP/2.
+
+To get a newer version of Apache, you can use the PPA from Ondřej Surý which includes the latest stable release (Apache 2.4.33 at time of writing). Ondřej is a prominent PHP developer in the Debian community, so this PPA is considered safe.
+
+To add the PPA, type:
+
+    sudo add-apt-repository ppa:ondrej/apache2
+
+Or, you can add the PPA manually by inserting these lines into /etc/apt/sources.list:
+
+    deb http://ppa.launchpad.net/ondrej/apache2/ubuntu xenial main 
+    deb-src http://ppa.launchpad.net/ondrej/apache2/ubuntu xenial main 
+
+Once the PPA is added, update and upgrade Apache:
+
+    sudo apt update
+    sudo apt upgrade
+
+This will update and upgrade apache2 to Apache 2.4.33+.
+## Step 2: Tell Apache to use PHP FastCGI
+
+You want to make Apache use a compatible PHP implementation by changing mod_php to php-fpm (PHP FastCGI). If your website or app breaks on FastCGI, you can always revert back to mod_php until further troubleshooting.
+
+# Install PHP FastCGI module for PHP 7.0 (replace with “7.1” if desired):
+
+    sudo apt install php7.0-fpm 
+
+Enable required modules, **proxy_fcgi** and **setenvif**:
+
+    sudo a2enmod proxy_fcgi setenvif
+
+Enable **php7.0-fpm**:
+
+    sudo a2enconf php7.0-fpm 
+
+_Disable_ the **mod_php** module:
+
+    sudo a2dismod php7.0 
+
+Restart Apache:
+
+    sudo service apache2 restart
+
+## Step 3: Change MPM from "prefork" to "event"
+
+Since the default "prefork" MPM (Multi-Processing Module) is not fully compatible with HTTP/2, you’ll need to change Apache’s current MPM to "event" (or "worker"). This is shown by the error message in Apache versions greater than 2.4.27 as – AH10034: The mpm module (prefork.c) is not supported by mod_http2.
+
+Keep in mind that your server requires more horsepower for HTTP/2 than for HTTP/1.1, due to the multiplexing feature and other factors. That said, smaller servers with low traffic may not see much difference in performance.
+
+First, disable the "prefork" MPM:
+
+    sudo a2dismod mpm_prefork 
+
+Enable the "event" MPM:
+
+    sudo a2enmod mpm_event 
+
+Restart Apache and PHP 7.0:
+
+    sudo service apache2 restart 
+
+    sudo service php7.0-fpm restart
+
+## Step 4: Add a line to your Virtual Host file
+
+Add the following line to your site’s current Virtual Host config file. This can go anywhere between the <VirtualHost>...</VirtualHost> tags. If you want to serve HTTP/2 for all your sites, add this to your global /etc/apache2/apache2.conf file instead of per each individual site’s Virtual Host file.
+
+    Protocols h2 h2c http/1.1
+
+_Explanation_: h2 is TLS-encrypted HTTP/2, h2c is cleartext HTTP/2, and http/1.1 is ordinary HTTP/1.1.
+
+Having http/1.1 at the end of the line provides a fallback to HTTP/1.1, while h2c is not strictly necessary.
+Step 5: Enable the mod_http2 Apache module
+
+Now you can enable the http2 module in Apache:
+
+    sudo a2enmod http2
+
+Restart Apache:
+
+    sudo service apache2 restart
+
+## Step 5 create http2.conf for entire Server HTTP2
+
+Create a new http2.conf
+
+    sudo nano /etc/apache2/conf-available/http2.conf
+
+and add all the following rows:
+
+    <IfModule http2_module>
+    Protocols h2 h2c http/1.1
+    H2Direct on
+    </IfModule>
+
+Enable the http2.conf by running
+
+    sudo a2enconf http2
+
+Restart your Apache2
+
+    service apache2 restart
+
+
+
+
+and enhance your ssl-vhost file (default-ssl.conf):
+
+    sudo nano /etc/apache2/sites-available/default-ssl.conf
+
+Amend the red ones in your configuration file:
+
+    ...
+    SSLEngine on
+    (&#x1F34E;)Protocols h2 h2c http/1.1
+    H2Push on
