Introduction<\/p>\n\n\n\n

Composer is an application for tracking the dependencies of a project. It pulls in all the required PHP packages. It allows to specify a set of libraries for a specific project. With the libraries established, it identifies the versions and dependencies and installs them to the corresponding project.

Prerequisites<\/p>\n\n\n\n

    \n
  1. SSH access with sudo privileges<\/li>\n\n\n\n
  2. Required PHP (>=5.3.2) version should be installed<\/li>\n<\/ol>\n\n\n\n

    Implementation<\/p>\n\n\n\n

    Step 1: Update the Local Repository<\/p>\n\n\n\n

    $sudo yum -y update<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Step 2: Install PHP Dependencies<\/p>\n\n\n\n

    $ yum install php-cli php-zip wget unzip<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    \"\"<\/a><\/figure>\n\n\n\n

    Step 3: Download Composer Installer Script<\/p>\n\n\n\n

    $ php -r “copy(‘https:\/\/getcomposer.org\/installer’, ‘composer-setup.php’);”<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Step 4: Download the authorized signature from Composer\u2019s Github page in the HASH variable<\/p>\n\n\n\n

    $HASH=”$(wget -q -O – https:\/\/composer.github.io\/installer.sig)”<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Step 5: Compare the official hash against the one which we  downloaded<\/p>\n\n\n\n

    $ php -r “if (hash_file(‘SHA384’, ‘composer-setup.php’) === ‘$HASH’) { echo ‘Installer verified’; } else { echo ‘Installer corrupt’; unlink(‘composer-setup.php’); } echo PHP_EOL;”

    ========
    Output:
    Installer verified
    ==========<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Step 6: Install Composer<\/p>\n\n\n\n

    $ php composer-setup.php –install-dir=\/usr\/local\/bin –filename=composer<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    \"\"<\/a><\/figure>\n\n\n\n

    Step 7: Check the installation <\/p>\n\n\n\n

    $composer<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    \"\"<\/a><\/figure>\n\n\n\n

    Step 8: To modify the composer version<\/p>\n\n\n\n

    $ composer self-update <required version><\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"
