OsCommerce is one of the most popular open source ecommerce applications available today. OsCommerce runs well on both Windows/IIS servers and on Linux/Apache servers. Installing OsCommerce onto your domain is just a matter of clicking a few buttons in the control panel. Here's how it's done:
First, log into your control panel using your username and password. Once you are in, scroll to the bottom of the page and look for the "OsCommerce" icon second group of icons from the bottom of the page. Click the icon.
You should now be on a page with a list of the domains you own with "Off" buttons to the right of the domains. To install OsCommerce onto one of the domains, click the "Off" button to turn it on.
A wizard will now guide you through the install process. Assuming you have not already created a database or user for OsCommerce, leave the wizard selections on the first page to "New Database" and "New User" and click the "Next" button.
On the second page of the wizard, give your database a name and optionally a description and press the "Next" button. The next page will then ask you for the username and password to be associated with the database. The username and password you are providing at this point is for the database connection, not for access to the OsCommerce Administrative area. Once you've filled in the username and password, click "Next" to continue. The screen will "hang" for a bit while the database is being created and oscommerce is being installed.
You will now have a subdirectory under your domain called "catalog" where your customers will interact with your store. There will be another directory called "admin" where you can configure the store. By default, the login for the admin area is the first 8 characters of your control panel login name and the password is the same as the password you use to log into the control panel.
Your OsCommerce store is now installed and you can go about the business of configuring the store to suit your needs.
