php-build can help you compile and manage different versions of PHP installations. Travis CI, a well-known continuous integration testing service, uses php-build.
Composer is a new generation of PHP package manager.
Composer Plugin combines the two. It is a plug-in for php-build that automatically installs Composer on each php-build build, so you don't have to install it manually.
Installation
Use the installation script
wget -O install.sh http://git.io/Hqr8pQ || curl -o install.sh http://git.io/Hqr8pQ && ./install.sh
Default installation to /usr/local/, set the PREFIX environment variable to switch Installation location.
Manual installation
First download the plug-in:
wget https://github.com/rogeriopradoj/php-build-plugin-composer/archive/master.tar.gz tar -vzxf master.tar.gz
In order to facilitate the update, you can also use git clone:
git clone https://github.com/rogeriopradoj/php-build-plugin-composer.git php-build-plugin-composer-master
Ensurecomposer.shhas executable permissions:
cd ~/php-build-plugin-composer-master chmod +x share/php-build/after-install.d/composer.sh
Finally, copy the share directory to your php-build installation, or set up the software Link:
Copy
cd ~/php-build-plugin-composer-master cp -r share /usr/local
Link
cd /usr/local/share/php-build/after-install.d ln -s ~/php-build-plugin-composer-master/share/php-build/after-install.d/composer.sh
Note, here we assume that you installed php-build to /usr/local (default location), if your php-build installation location is different, you need to adjust the above command.
There is nothing to say about using
. Just use php-build as usual, composer will be installed automatically, no need to worry.
