The PHPCI Worker (added in v1.7) runs in the background on your server and waits for new builds to be added to a Beanstalkd queue. Unless already running a build, the worker will pick up and start running new builds almost immediately after their creation.
The worker is the recommended way to run PHPCI builds. You can run several workers all watching one queue, allowing jobs to be run simultaneously without the overhead of polling your MySQL database.
apt-get install beanstalkd.
Setting up the worker on a new installation of PHPCI is as simple as entering the appropriate values for your Beanstalkd server hostname and queue name when running the PHPCI installer. By default, the installer assumes that you'll be using beanstalkd on
localhost and will use the queue name
On an existing installation, to set up the worker, you simply need to add the beanstalkd host and queue names directly into your
/PHPCI/config.yml file. You should add a
worker key beneath the
phpci section, with the properties
queue as outlined in the screenshot below:
Once you've set up PHPCI to add your jobs to a beanstalkd queue, you need to start the worker so that it can pick up and run your builds. On most servers, it is best to manage this using supervisord. The following instructions work on Ubuntu, but will need slight amendments for other distributions.
Using your preferred text editor, create a file named
/etc/supervisor/conf.d. In it, enter the following config:
[supervisord] logfile = /tmp/supervisord.log logfile_maxbytes = 50MB logfile_backups = 10 loglevel = info pidfile = /tmp/supervisord.pid [program:phpci] command=/path/to/phpci/latest/console phpci:worker process_name=%(program_name)s_%(process_num)02d stdout_logfile=/var/log/phpci.log stderr_logfile=/var/log/phpci-err.log user=phpci autostart=true autorestart=true environment=HOME="/home/phpci",USER="phpci" numprocs=2
You'll need to edit the '/path/to/phpci', the
user value and the
environment value to suit your server. The user needs to be an actual system user with suitable permissions to execute PHP and PHPCI.
Once you've created this file, simply restart supervisord using the command
service supervisor restart and 2 instances of PHPCI's worker should start immediately. You can verify this by running the command
ps aux | grep phpci, which should give you output as follows:
➜ ~ ps aux | grep phpci phpci 19057 0.0 0.9 200244 18720 ? S 03:00 0:01 php /phpci/console phpci:worker phpci 19058 0.0 0.9 200244 18860 ? S 03:00 0:01 php /phpci/console phpci:worker
That's it! Now, whenever you create a new build in PHPCI, it should start building immediately.
