¿Cómo instalar Composer en Linux?

Método 1:

# Moverse a /usr/bin
cd /usr/bin

# Descargar composer (tener instalado php)
curl -sS https://getcomposer.org/installer | sudo php

# Renombramos de composer.phar a composer
sudo mv composer.phar composer

Método 2:

# Descargar composer
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

# Verificar integridad del archivo composer-setup.php
php -r "if (hash_file('sha384', 'composer-setup.php') === 'dac665fdc30fdd8ec78b38b9800061b4150413ff2e3b6f88543c636f7cd84f6db9189d43a81e5503cda447da73c7e5b6') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"


# Instalar composer
php composer-setup.php

# Eliminar el archivo 'composer-setup.php' luego de su instalación
php -r "unlink('composer-setup.php');"

# Mover el archivo 'composer.phar' y renombrarlo además de hacer que el comando se pueda ejecutar globalmente
sudo mv composer.phar /usr/local/bin/composer
