How to Install Drush Manually?

Drupal websites may be managed, controlled, and altered using Drush, a shell-based computer program.

A composer is a PHP dependency management used by the Drush installation process. Therefore, before installing Drush, you must install composer on your account.

# Steps to install Drush :

1. Log in to your account using SSH.

2. Select the Drush version that you wish to install :

Install Drush 8 by typing following command :

composer global require drush/drush: 8. x

Install Drush 7 by typing following command :

composer global require drush/drush: 7. x

3. Now determine the CentOS version used on your server by typing following command :

uname -r

If you get an output of this command containing eI7 (for example, 3.10.0-714.10.2.Ive1.5.9.el7.x86_64), then your server is running CentOS7.

If you get an output of this command containing eI6 (for example, 2.6.32-673.23.1.Ive1.4.27.el6.x86_64). then your server is running CentOS6.

4. In order to add Drush to your path, type the following commands depending on the CentOS version that you have obtained in step 3 :

For the server running CentOS 7, type the following command :

echo 'export PATH="$HOME/.config/composer/vendor/bin:$PATH" '>> ~/ .bashrc

For the server running CentOS 6, type the following command :

echo 'export PATH="$HOME/ .composer/vendor/bin:$PATH" ' >> ~/ .bashrc

5. To make the new path effective immediately, type the following command :

source ~/.bashrc

Now you can see Drush is now installed and is ready to use.

If you want to confirm if Drush is installed correctly, then type the following command :

drush version

Dursh will show you the recent version number.

If you want to update Drush to the newest version, then type the following command :

composer global update
