Install PHP Composer

Composer is PHP’s dependency manager. The Statusengine 3 worker and Statusengine UI are both installed with it.

ℹ️

Only Statusengine 3 needs this. The current Go worker is a single binary with no PHP and no Composer anywhere in the picture.

Installation

apt-get install php-cli
curl -o composer-setup.php https://getcomposer.org/installer

php composer-setup.php
cp composer.phar /usr/local/bin/composer

Usage

You should now be able to run composer and get its help output:

root@ubuntu:~# composer
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Continue as root/super user [yes]? yes

Usage:
  command [options] [arguments]

The warning about running as root is expected here: Statusengine 3 is installed system-wide under /opt/statusengine or /usr/share, so the install step does run as root.
