Global Installation of Composer (manual)

  • 772

I followed composer manual (global installation of composer (manual)) to install composer on Ubuntu.

$ ll /usr/local/bin/
total 4760
drwxr-xr-x  2 root root    4096 2012-03-29 08:29 ./
drwxr-xr-x 10 root root    4096 2011-04-26 00:50 ../
-rwxr-xr-x  1 root root  410324 2012-03-29 08:28 composer.phar

Other scripts from /usr/local/bin/ works, but composer gives:

$php composer.phar update Could not open input file: composer.phar

It works only if I enter absolute path to composer.phar. How to fix this?

php binary

  1. TLDR;

    As described on the Composer website:

    curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

    Manual Method

    I found an easier way to globally install composer than the manual proscribed in the github readme.md. It's actually on the getcomposer.org website:

    curl -s http://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/

    And if you're even more lazy, like me, you can create an alias:

    alias composer='/usr/local/bin/composer.phar'

    This way you can invoke composer with just composer

    Don't add php in the beginning. Just call composer.phar.

  3. Actually, getcomposer.org now recommends a simpler method:

    $ curl -sS https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer

    Now you can just use composer without bothering with an alias or a separate sh script.

  4. Another alternative to get a nice composer command instead of composer.phar:

    $ curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin
$ ln -s /usr/local/bin/composer.phar /usr/local/bin/composer

  5. for easier execution I created /usr/local/bin/composer with content:

    #!/bin/sh
exec /usr/local/bin/composer.phar "$@"

    dont forget about sudo chmod +x /usr/local/bin/composer.phar

  6. Below are the steps to be followed to install composer globally: 1. Before installing Composer, make sure our server has all dependencies installed.

    1st, update the package manager cache by running:

    $ sudo apt-get update

    2. Now, let's install the dependencies. We'll need

    • curl => to download Composer
    • php5-cli => installing and running it
    • git => used by Composer for downloading project dependencies

    Everything can be installed with the following command:

    $ sudo apt-get install curl php5-cli git

    3. Composer installation with a single command:

    curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

    4. This will download and install Composer as a system-wide command named composer, under /usr/local/bin. The output should look like this:

    Output:

    \#!/usr/bin/env php
All settings correct for using Composer
Downloading...

Composer successfully installed to: /usr/local/bin/composer

    Use it: php /usr/local/bin/composer

    5. To test your installation, run:

    $ composer -V

    Output:

    Composer version 1.1.3 2016-06-26 15:42:08
    1. Installation Successful

  7. I have made a simple bash script that automatically installs composer for current user/all users, you can one of the following commands in your terminal to use bash script.

    Current User

    wget -O - https://gist.github.com/EmpireWorld/1dd5f59566e186907f99dc16badc382a/raw/install-composer-local.sh | bash

    All Users

    wget -O - https://gist.github.com/EmpireWorld/1dd5f59566e186907f99dc16badc382a/raw/install-composer-global.sh | bash

  8. This might work for you. Note that sudo is used two times here.

    sudo curl -sS https://getcomposer.org/installer | sudo php
