Editing PHP/HHVM

First, install HHVM:

https://www.howtoforge.com/tutorial/how-to-install-wordpress-with-hhvm-and-nginx-on-centos-7/

For better performance, set up HHVM as a UNIX socket to reduce additional load from TCP layers.

== Systemd Service ==

Make sure you've installed Nginx from the official nginx repos, rather than your distribution's outdated versions. On both Debian and CentOS, this will result in the creation of an nginx user and group, which is then made accessible in the systemd service below:

{{hc|/etc/systemd/system/hhvm.service|<nowiki>
[Unit]
Description=HHVM HipHop Virtual Machine (FCGI)
After=network.target nginx.service mariadb.service
 
[Service]
User=nginx
Group=nginx
ExecStart=/usr/local/bin/hhvm --config /etc/hhvm/server.ini --user nginx --mode daemon -vServer.Type=fastcgi -vServer.FileSocket=/var/run/hhvm/hhvm.sock
 
[Install]

-The PHP engine runs the MediaWiki source code. However, rather than using the conventional PHP engine, this configuration will use Facebook’s HHVM for significantly higher performance. Follow these instructions to set up the HHVM package:

-Now, reload the systemd services. You only need to do this whenever you edit the systemd service files.
-sudo systemctl daemon-reload
-Finally, start HHVM.
-sudo systemctl start hhvm
-If it works out, enable the hhvm service.
-sudo systemctl enable hhvm
