How to install Composer globally on linux?

Question

Usually, when we install Composer, I usually do so:

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

It downloads a file called composer.phar. But then I have to keep putting the path of the folder every time I run.

For example:

~/downloads/composer.phar 

I’d like to do just that on the command line:

 composer self-update && composer update

How can I do this on Linux?

Answer 1

The solution to this is just to move the downloaded file to the folder /usr/local/bin.

Come on.

1) First download the Composer file:

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

2) I believe that before moving it is only necessary to give execution permission:

 sudo chmod +x composer.phar

3) And then, just move it:

sudo mv composer.phar /usr/local/bin/composer

If you don’t have the curl installed, you can run the command:

 sudo apt-get install curl

Or use one of these options instead of the first step:

php -r "readfile('https://getcomposer.org/installer');" | php

Or

wget https://getcomposer.org/composer.phar 

Answer 2

First, download the installer of Composer in any folder:

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

Then use the command mv to move the Composer file to the folder where linux recognizes the commands:

mv composer.phar /usr/local/bin/composer

There you can use in the terminal

composer install ...

Aliases

An alias could solve

vi ~/.bashrc

add

alias nome_do_alias=comando

example

alias composer=/a/pasta/onde/estah/conposer.phar

The alias feature varies according to the Linux distribution, but overall is similar to the above example.

Symbolic link

Another even simpler way is to create a Symbolic link

ln -s /local/do/arquivo/composer.phar composer
