Run builds using a worker
The PHP Censor Worker 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 PHP Censor builds. You can run several workers all watching one queue, allowing jobs to be run simultaneously without the overhead of polling your database.
You need to install Beanstalkd - On Ubuntu, this is as simple as running
apt-get install beanstalkd.
Systemd or Supervisord needs to be installed and running on your server.
Setting up the PHP Censor worker
On a new installation
Setting up the worker on a new installation of PHP Censor is as simple as entering the appropriate values for your
Beanstalkd server hostname and queue name when running the PHP Censor installer. By default, the installer assumes that
you'll be using beanstalkd on
localhost:11300 and will use the queue name
On an existing installation
On an existing installation, to set up the worker, you simply need to add the beanstalkd host and queue names directly
config.yml file like:
php-censor: queue: use_queue: true host: localhost port: 11300 name: php-censor-queue lifetime: 600
Running the PHP Censor worker
You can use systemd to run the worker. Configuration for the unit is almost the same as supervisord's configuration.
Just copy this config to
/etc/systemd/system/php-censor.service with right permissions, enable
systemctl enable php-censor.service and run it by
systemctl start php-censor.service. If you want to start more
than one worker, just create more unit files with different name and repeat previous steps.
[Unit] Description=PHPCensor Worker After=network.target [Service] Type=simple ExecStart=/your/path/bin/console php-censor:worker Restart=always #Could be changed User=php-censor #Could be changed Group=php-censor [Install] WantedBy=multi-user.target
And check that it works properly by
systemctl status php-censor.service
Also you can use Supervisord to run the worker. Once you've set up PHP Censor 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:
[program:php-censor] command=/path/to/php-censor/bin/console php-censor:worker process_name=%(program_name)s_%(process_num)02d stdout_logfile=/var/log/php-censor.log stderr_logfile=/var/log/php-censor-err.log user=php-censor autostart=true autorestart=true environment=HOME="/home/php-censor",USER="php-censor" numprocs=2
You'll need to edit the '/path/to/php-censor', 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 PHP Censor.
Once you've created this file, simply restart supervisord using the command
service supervisor restart and 2
instances of PHP Censor's worker should start immediately. You can verify this by running the command
ps aux | grep php-censor, which should give you output as follows:
➜ ~ ps aux | grep php-censor php-censor 19057 0.0 0.9 200244 18720 ? S 03:00 0:01 php /php-censor/console php-censor:worker php-censor 19058 0.0 0.9 200244 18860 ? S 03:00 0:01 php /php-censor/console php-censor:worker
Simple start with nohup (not recommended)
Also you can simple daemonise worker by
nohup /path/to/php-censor/bin/console php-censor:worker &> /var/log/php-censor-worker.log </dev/null & # and you can save pid in pidfile with echo "$!" > /var/run/php-censor-worker.pid, but it's not really necessary
But keep in mind: it won't restart your worker if it fails and can be inconvenient to manage worker process in contrast with other solutions. So, it's good for debug purposes or as temporary solution.
That's it! Now, whenever you create a new build in PHP Censor, it should start building immediately.
