Drupal multisite server provision scripts set.

Requirements.

• Drupal 7,8
• Apache web server

NOTE: This solution doesn't work with NGINX web server.

Download and install.

Composer is recommended way to get files in your drupal project. Just use command composer require bellcom/os2subsites_provision.

Composer specific settings.

For composer based stack you will need to add specific settings to composer.json file.

1. Override default installed path for composer installer.

By default bellcom/os2subsites_provision will be installed as drupal-module. Add extra line to your composer.json to override default path.

Add this line

"scripts/os2subsites_provision": ["bellcom/os2subsites_provision"],

above line define path for drupal modules

    "extra": {
        ...
        "installer-paths": {
            ...
            "scripts/os2subsites_provision": ["bellcom/os2subsites_provision"],
            "web/modules/contrib/{$name}": ["type:drupal-module"],
            ...
        }
        ...
    }

2. Check local and config files.

Composer will keep os2subsite_provision code base updated and stable. It means that all extra files will be removed from os2subsites_provision directory, includes config and local files. To add files back after every composer install/update add following command to composer.json scripts section.

    "scripts": {
        ...
        "post-install-cmd": [
             ...
            "./scripts/os2subsites_provision/check_config.sh scripts/os2subsites_provision_config"
             ...
        ],
        "post-update-cmd": [
             ...
            "./scripts/os2subsites_provision/check_config.sh scripts/os2subsites_provision_config"
             ...
        ]
    },

To manage subsites there are drupal module that triggering server scripts. See how to add module below.

Allow web server run os2subsites_provision scripts.

To allow web server run scripts that will handle subsites you need to allow apache user run this scripts with sudo rights without password. To allow Apache user www-data run os2subsites scripts add following line to /etc/sudoers.d/os2subiste_provision file.

www-data   ALL=(root) NOPASSWD: /var/www/[your-project]/scripts/os2subsites_provision/subsite_add_domain.sh
www-data   ALL=(root) NOPASSWD: /var/www/[your-project]/scripts/os2subsites_provision/subsite_create.sh
www-data   ALL=(root) NOPASSWD: /var/www/[your-project]/scripts/os2subsites_provision/subsite_delete.sh
www-data   ALL=(root) NOPASSWD: /var/www/[your-project]/scripts/os2subsites_provision/subsite_remove_domain.sh
www-data   ALL=(root) NOPASSWD: /var/www/[your-project]/scripts/os2subsites_provision/reload.sh

Restart web server after adding to apply changes.
