Note: HHVM doesn’t play with all WordPress themes and plugins. Test your site properly before using this in production.
Installation of HHVM:
For installation of HHVM please follow this guide:
https://github.com/facebook/hhvm/wiki/Prebuilt%20Packages%20for%20HHVM
Post installation:
We need to configure our web server to use HHVM,
sudo /usr/share/hhvm/install_fastcgi.sh
You can ignore the WARNING from following message.
# sudo /usr/share/hhvm/install_fastcgi.sh
Checking if Apache is installed
WARNING: Couldn't find Apache2 configuration paths, not configuring
Checking if Nginx is installed
Detected Nginx installation
Checking for custom Nginx configuration
WARNING: Detected clashing configuration. Look at /etc/nginx/hhvm.conf for information how to connect to the hhvm fastcgi instance.
#
Configuring HHVM:
Editing server.ini:
Open server.ini file:
vim /etc/hhvm/server.ini
If HHVM crashed then site must use PHP-FPM as fallback, so change HHVM server port from 9000 to 8000
hhvm.server.port = 8000
Editing php.ini
Open php.ini file:
vim /etc/hhvm/php.ini
Add following towards end of file:
hhvm.log.header = true
hhvm.log.natives_stack_trace = true
Editing hhvm.conf:
Note: This editing is not required, as we are not using this file, but if have included hhvm.conf in your previous site then you also need to change HHVM port here.
vim /etc/nginx/hhvm.conf
and change HHVM port from 9000 to 8000:
fastcgi_pass 127.0.0.1:8000;
Configuring FastCGI:
Open fastcgi.conf file:
vim /etc/nginx/conf.d/fastcgi.conf
and add following line towards end of file:
fastcgi_keep_conn on;
Use HHVM and adding PHP5-FPM as fallback:
Open Upstream.conf file:
vim /etc/nginx/conf.d/upstream.conf
and make sure it look like this:
# Common upstream settings
upstream php {
# server unix:/run/php5-fpm.sock;
server 127.0.0.1:8000;
server 127.0.0.1:9000 backup;
}
upstream debug {
# Debug Pool
server 127.0.0.1:9001;
}
Restart Services:
service hhvm restart
php5-fpm -t && service php5-fpm restart
nginx -t && service nginx restart
Testing:
- Using web browser:
Just point your browser to https://example.com:22222/php/info.php, if you are seeingHipHopthen, your server is using HHVM, otherwise it is using FPM - Using CURL:
Use following command to test from command line:
curl -I example.com
If you are able to see line like this:
X-Powered-By: HHVM/3.2.0
then your site is using HHVM, otherwise FPM
Log File:
You should check the HHVM error log file for any issues related to your site.
tail -f /var/log/hhvm/error.log
