It appears you are not a Professional System Administrator (or similar). Questions about software that runs on a "server" (a pretty meaningless classification in the broad scheme of things) aren't automatically on-topic on Server Fault.
Please have a look through our FAQ. Once done, take a look at Super User and Unix & Linux, as these sites are more appropriate for user questions.
Any question that can be simply answered by "Read the Friendly Manual" and pointing to a semi-obvious spot in the documentation is off-topic for Server Fault.
