hhvm support checklist

Related to #180

• Analyze https://github.com/facebook/hhvm/search?q=wordpress&type=Issues
• test wp-cli
• what happens to php5-fpm (max children reached monitoring etc)
• does xdebug works nicely?
• what about zend-opcache?
• Analyze upstart script - http://community.rtcamp.com/t/hhvm-upstart-script/3450/7

We will need following for automatic search and replace php location bloc:

grep -lr "location ~ .php" . | xargs sed -i -e 's/\.php\$/\\\.\(hh\|php\)\$/g'

grep -lr "location ~ \\\\\.php\\$" . | xargs sed -i -e 's/\\\.php\$/\\\.\(hh\|php\)\$/g'

add fastcgi_keep_conn on; inside /etc/nginx/conf.d/fastcgi.conf

[rahul286]

Inside /etc/nginx/hhvm.conf

location ~ \.(hh|php)$ {
    fastcgi_keep_conn on;
    fastcgi_pass   127.0.0.1:9999;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

Packages used: https://github.com/facebook/hhvm/wiki/Prebuilt%20Packages%20for%20HHVM

Important: Configure your webserver to use HHVM:

sudo /usr/share/hhvm/install_fastcgi.sh

For Ubuntu 12.04, boost 1.49 is required (or recommended)

https://github.com/facebook/hhvm/wiki/Building-and-installing-HHVM-on-Ubuntu-12.04#installing-boost-149

[rahul286]

For debug logs:

File: /etc/default/hhvm has

Line: ## "-vLog.Level=Debug" Enable debug log level

[rahul286]

Some workaround needed to get timestamps in logs:

Ref: facebook/hhvm#1122 (comment)

Inside file: /etc/hhvm/php.ini

Add: hhvm.log.header = true

And restart hhvm

[rahul286]

server.ini and php.ini together creates confusion.

In /etc/init.d/hhvm both files are used.

 # Default values. This values can be overwritten in '/etc/default/hhvm'
CONFIG_FILE="/etc/hhvm/server.ini"
SYSTEM_CONFIG_FILE="/etc/hhvm/php.ini"

Then both files are passed to command-line as:

DAEMON_ARGS="--config ${SYSTEM_CONFIG_FILE} \
--config ${CONFIG_FILE}

I think it will be good if we use php.ini and leave server.ini untouched. I think server.ini is useful for builtin web-server. In our case we are using nginx as our web-server and php is processed via fastcgi.

I get a Detected clashes error with sudo /usr/share/hhvm/install_fastcgi.sh

Does zend opcache work with hhvm

i am not able to see the opcache viewer in :2222

[solhuebner]

Does this make any sense and how to do it exactly? "There were a few gotchas, hhvm's install script didn't work, detected a class or whatever with Nginx. So I just made a symlink for hhvm.conf in conf.d and continued on."

[joeguilmette]

Sorry, could've been more specific.

When you run HHVM's install script it throws an error because it detects
some of the same settings already exist in nginx.conf

So I had to manually install HHVM.
