Step 1:
Login to cPanel (login details are in your account information email).

Step 2: Record your server name for later usage (as shown below).

Step 3: Click on the fantastico icon (as shown below).

Step 4: Click on the link for OS Commerce (under E-Commerce & shown below).

Step 5: Click on the link for New Installation (as shown below).

Step 6 (MOST IMPORTANT STEP): Define the installation location (as shown below).

A. Select your domain name from the drop down menu.

B. Enter the name of a directory where you wish osCommerce to install.

WARNING! The "install in directory" field is where a lot of clients go wrong. You should enter a single word of a new folder that will be created for osCommerce. Do NOT enter ANY slashes!
 

C. Double check what you entered in the "Intall in directory" field. If you wanted your website visitors to access your oscommerce store when they went to http://yourdomain.com, you would NOT enter anything in the "Install in directory" field (you would leave it blank). However, if you already have a website (you have upload webpages), you would want to enter a directory name (single word) in the "install in directory" field. For example, in our image above, you can see we entered the word "store". If you decided to enter "store", you would access osCommerce by going to http://yourdomain.com/store/ (you would use your actual domain name though).

Step 7: Enter a username & password of your choosing (as shown below).

Step 8: Enter a shop name, owner name, and email addresses (as shown below).

The shop name, owner's name, email sender, and your email address fields are all pretty self explanitory.

Enter your details and proceed to step 8, which still falls under the Base configuration, but the other fields need a little more explanation.

Step 9: Set Use SSL to Yes (as shown below).

Step 10: Enter your Secure Server Hostname (as shown below).

If you have an ssl certificate for your domain name, you can just enter your domain name in this field. Otherwise, enter your servername, forward slash, tilda, your cpanel username ( centos.securenet-server.net/~acenet ).



Step 11: Select information you want to require from your clients (as shown below).

These self explanitory variables and can be set to Yes (required ) or No.



Step 12: Click Install OS Commerce (as shown below).

Step 12: On the next page, click Finish installation (as shown below).

END: YOU'RE DONE!
