Once you do that, you will need to upload it on your account using the File Manager Tool or via FTP. (Please make sure you upload it in your public_html folder)
Next you need to unpack it by selecting the package and then choosing extract as described on the screenshot.
The files are extracted to a folder named after the version of the PostNuke. You can change the name to the one you want by clicking on the folder and selecting Rename.
Next, please, create a new database from the cPanel – MySQL Databases Area.
Add a username from the cPanel – MySQL Databases Area and add it to the database.
Point your browser to http://yoursite.com/path/to/install.php (if you installed postnuke directly into the www folder on your site, then you would point your browser to http://yoursite.com/install.php
Step 1: Select your language, and then click set language.
Read and accept the General Public License agreement, and click Next.
If the files config.php and config-old.php are set to CHMOD 666 you will see checkmarks indicating this. Click Continue.
! NB: If you do not see the same as the image above, please login to the File Manager tool and set the config.php and config-old.php to 666.
Enter your database information.
Step 4: Setup the Database
Database Host: localhost
Database name: username_database (the name of the database you created. Please note that it gets the user prefix. For example if you add a database called pnuke and your cPanel username is uname the full name of the database is uname_pnuke.
Database username: the username that you created. (Same as the database rules)
Database password: the password for the username.
Table prefix: nuke (it’s a good one for table prefix)
Database type: MySQL
Database Table Type: MyISAM
Leave the rest as it is and click Submit.
