The following snippets can be used to remove your Magento 1.x installation(s).

This is irreversible so make sure you know what you are doing!

Remove a Magento 1 Installation Using Magerun

In order to uninstall/remove a Magento 1.x installation, run the following command:

n98-magerun --root-dir=/data/web/public uninstall --installationFolder=/data/web/public --force

This will delete the default database (YOURAPPNAME_preinstalled_Magento), and recursively delete the /data/web/public directory. Any instances of Magento installed in other directories will not be touched.

Manually Remove a Magento 1.x Installation

To manually remove all databases and files of both the staging and production, use the following snippet:

mysql -Be 'show databases' | sed 1d |\
 grep -vE '^information_schema$|^performance_schema$|^mysql$|^test$' | while read DATABASE
do
    mysql -Be "DROP DATABASE $DATABASE"
done

Then remove all Magento files, use the following command:

cd /data/web
rm -rf /data/web/{public,staging}
mkdir /data/web/{public,staging}

Keep in mind: After removing your Magento content and database, sometimes you need to remove or adjust your Nginx configuration in /data/web/nginx too, in order to start with a clean slate.
