CPanel Web host management software provides an intuitive interface for managing a website server. When running complex scripts on the server, you may occasionally need to stop a process from running to prevent a server crash. You can either stop all processes that a certain user is running, or you can stop a specific process by selecting it from a list of live processes.
Type he server IP address followed by a colon and 2087 or follow your hosting server company or co-location center's directions for accessing CPanel. Enter the administrator user name and password in the text fields when the CPanel login screen appears.
