An Ansible role that installs Drush on Linux.

Supports global installation via Composer or via packaged download (faster).

• Composer (only required if installing via Composer rather than from a packaged download).
• PEAR (only required to install Drush 6 & below).

Available variables are listed below, along with their default values (see defaults/main.yml):

drush_install_path: /usr/local/share/drush

The location of the entire drush installation (includes all the supporting files, as well as the drush executable file.

drush_path: /usr/local/bin/drush

The path where drush will be installed and available to your system. Should be in your user's $PATH so you can run commands simply with drush instead of the full path.

drush_version: 8.1.0

The version of Drush to install (examples: "8.0.2", "7.x", "7.1.0", "master"). This should be a string as it refers to a git branch, tag, or commit hash.

drush_prefer_packaged_download: true

If set to true, the role will attempt to install Drush from a downloaded .phar file. Note that .phar files are only available through later releases of Drush and will require drush_version to be set to 8.0.0-rc3 or higher.

drush_composer_path: /usr/local/bin/composer

Path to where Composer is installed.

drush_keep_updated: no

Whether to keep Drush up-to-date with the latest revision of the branch specified by drush_version.

Hat tip to @geerlingguy. Some of this role is based on his Drush role.
