Is the Magento software installed already?
To determine if the Magento software is installed already, you can access the Magento Admin (administration console) or storefront using a web browser.
Prerequisite: You must know the Magento server’s host name or IP address, and the URL to access the Magento installation. If you’re not sure, find the information from your system administrator or hosting provider.
Then open a web browser and go to the URL you were provided. Some examples follow:
http://www.example.com/magento2/admin https://www.example.com/admin http://www.example.com
If a 404 (Not Found) error displays, Magento probably isn’t installed. You should confirm that with your system administrator or hosting provider.
If Magento is installed, you should see something like the following after you log in:
