README
Transform any class in a *nix daemon process or cron job without changes or refactoring.
Motivation
Some times we need to create a cron tab or a process for running in background. The most of times we need to create a new class, probably in a different framework and have to set or even choose another language for create the job/daemon.
"Daemonize" enables you to can create a linux daemon or a job for use in a cron tab without change you pre-existing class.
"Daemonize" is a script that create a "init.d" script and encapsulate or class enabling you to run it in the bash, for example.
How to
Suppose you have a pre-existing class for read some info from database and run some action with these data. For example:
<?php namespace Some\Name\Space; class MyExistingClass { // ... public function someExistingMethod() { // Your code } // ... }
If you want transform this class and method in a linux daemon (or "daemonize" it) you have to first create a bootstrap php file.
The most simple bootstrap is vendor/autoload.php
but you can create a more complex bootstrap file if you need.
Below is an example of a bootstrap file:
require_once __DIR__ . "/vendor/autoload.php"; // Your code here
Now, if you want to test it you can run the command:
daemonize run \ "\\Some\\Name\\Space\\MyExistingClass::someExistingMethod" \ --bootstrap "relative/path/to/bootstrap.php" \ --rootdir "/path/to/root" \ --http-get "param1=value1¶m2=value2"
You can test with:
daemonize run \
"\\ByJG\\Daemon\\Sample\\TryMe::ping"
--arg value1
--arg value2
If everything is ok, now you can "daemonize" this class (as root):
daemonize install --template=systemd mydaemon \ --class "\\Some\\Name\\Space\\MyExistingClass::someExistingMethod" \ --bootstrap "relative/path/to/bootstrap.php" \ --rootdir "/path/to/root"
note: valid templates are:
- systemd (default)
- upstart
- initd
- crond
Now for start or stop the service you need only
sudo service mydaemon start # or stop, status or restart
For uninstall just type:
daemonize uninstall mydamon
and list all "daemonized" php classes
daemonize services --only-names
Install
Daemonize does not need to be associated to your PHP project. You can either as a global package or as a local package.
composer global require "byjg/php-daemonize"
sudo ln -s /root/.composer/vendor/bin/daemonize /usr/local/bin/daemonize
If you want to share this installation with another users consider use the command chmod a+x /root
. The root
directory will remain unreadable for them, but you'll can execute the script "daemonize".
Running a pre-installed demo
Open two terminals.
First do :
touch /etc/tryme.txt tail -f /etc/tryme.txt
On the second do:
sudo daemonize install --template=upstart tryme "\\ByJG\\Daemon\\Sample\\TryMe::process" "vendor/autoload.php" "./" sudo service tryme start
If everything is OK, will see on the first terminal a lot of lines added. Do not forget to run sudo service tryme stop
