# How to install the hhvm package using yum on CentOS 6.6 with Plesk 11.5
# Note that you can also install hhvm from source. For that check the official guides here: 
# https://github.com/facebook/hhvm/wiki/Building-and-installing-HHVM-on-CentOS-6.6#13-install-ocaml

cd /etc/yum.repos.d

sudo wget http://www.hop5.in/yum/el6/hop5.repo

yum clean all

yum install hhvm

# For me this threw the following dependecy error:
# Error: Package: psa-libxml-proxy-2.7.8-13032215.x86_64 (@PSA_11_5_30-dist)
#           Requires: libboost_program_options.so.5()(64bit)
#           Removing: boost-program-options-1.41.0-27.el6.x86_64 (@base)
#               libboost_program_options.so.5()(64bit)
#           Updated By: boost-program-options-1.54.0-7.el6.x86_64 (hop5)

# Install boost first
wget http://www.hop5.in/yum/el6/boost-program-options-1.54.0-7.el6.x86_64.rpm
rpm -ivh boost-program-options-1.54.0-7.el6.x86_64.rpm

yum install hhvm

# Check if hhvm is working
hhvm --version

# Plesk 11.5 comes with Apache 2.2, so install mod_fastcgi
yum install libtool httpd-devel apr-devel apr
cd /opt
wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz
tar -zxvf mod_fastcgi-current.tar.gz
cd mod_fastcgi-2.4.6/
cp Makefile.AP2 Makefile
make top_dir=/usr/lib64/httpd
make install top_dir=/usr/lib64/httpd

# Have Apache load the module
vi /etc/httpd/conf.d/mod_fastcgi.conf
# Add this line
LoadModule fastcgi_module modules/mod_fastcgi.so

service httpd restart

# Make sure the module is loaded
apachectl -M |grep fastcgi
# Should output:
# fastcgi_module (shared)
# Syntax OK

# !Important: Disabe PHP support for the virtual host, otherwise the regular PHP handler will handle PHP requests.

# Next create a config file for HHVM:
vim /etc/hhvm/hhvm.hdf

# This is the content of my hhvm.hdf config file (note that the log level is set to Verbose, for production you can lower that)

# Restart Apache
service httpd restart

# Test it: create a php file in your virtual host's document root, i.e. test.php
vim /var/www/vhosts/hhvm.example.com/test.php

# Add the following content to test.php:
<?php
echo  defined('HHVM_VERSION')?'Using HHVM':'Not using HHVM';

# Finally open a webbrowser and navigate to the test.php file. It should return 'Using HHVM' if everything is working.
# If not then check the log files under /var/log/hhvm (make sure this directory exists!)
