HHVM is an open-source virtual machine designed for executing programs written in Hack and PHP. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the development flexibility that PHP provides.<a href="https://2.bp.blogspot.com/-ijr19P1E8s0/WDwyDax_csI/AAAAAAAABt0/Haqo0UYh4gArtEGZG46zJ7fO-M-nB9A6QCLcB/s1600/WikipediaHHVM650.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" src="https://2.bp.blogspot.com/-ijr19P1E8s0/WDwyDax_csI/AAAAAAAABt0/Haqo0UYh4gArtEGZG46zJ7fO-M-nB9A6QCLcB/s1600/WikipediaHHVM650.jpg" /></a> 
 
HHVM supports Hack, PHP 5 and the major features of PHP 7. We are aware of minor incompatibilities, so please open issues when you find them. HHVM also supports many extensions as well.

Install Apache: 
 
Apache package is available from Ubuntu repository, so you can easily install it with apt command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; color: white; font-family: monospace, serif; font-size: 14px; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">sudo apt-get update
sudo apt-get install -y apache2 unzip</pre>
Once the installation is complete, start the Apache service. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; color: white; font-family: monospace, serif; font-size: 14px; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">sudo systemctl start apache2</pre>
Verify whether Apache service is running. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; color: white; font-family: monospace, serif; font-size: 14px; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">sudo systemctl status apache2

Install and Configure MariaDB: 
 
We will use MariaDB instead of MySQL database. MariaDB is a fork of MySQL developed by MariaDB Foundation, led by Michael "Monty"Widenius. 
<div style="clear: both; margin: 10px 0;">
<center>
<script async="" src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

</div>
MariaDB is available in Ubuntu base repository. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; color: white; font-family: monospace, serif; font-size: 14px; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">sudo apt-get install -y mariadb-client mariadb-server</pre>
Start MariaDB service. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; color: white; font-family: monospace, serif; font-size: 14px; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">sudo systemctl start mysql</pre>
 
Verify MariaDB is running as expected.

Login with the root and create a database for our WordPress installation. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo mysql -u root -p

grant all privileges on testdb.* to wpdbuser@localhost identified by 'wp@123';

</pre>
Install and Configure HHVM: 
 
Let’s add HHVM repository to your system. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo apt-get install -y software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449 
sudo add-apt-repository "deb http://dl.hhvm.com/ubuntu $(lsb_release -sc) main"</pre>
Update the Ubuntu repositories and Install HHVM 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo apt-get update
sudo apt-get install -y hhvm
</pre>
Once the installation is complete, configure Apache web server to use HHVM. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo /usr/share/hhvm/install_fastcgi.sh</pre>
Run below command to start HHVM automatically on system boot up. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo update-rc.d hhvm defaults</pre>
Here, We’ll use HHVM as a PHP alternative. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo /usr/bin/update-alternatives --install /usr/bin/php php /usr/bin/hhvm 60</pre>
Now start HHVM service. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">sudo systemctl start hhvm</pre>
Verify the php version. You should get the similar output like below. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; outline: 0px; overflow: auto; padding: 10px !important; vertical-align: baseline; width: auto !important; word-break: break-all;">$ php -v
