Managing Services and Daemons on RHEL

A UNIX daemon is a program that runs in the background and is independent of control from a

terminal. Daemons can either be started by a process (such as a system startup script, where there is no

controlling terminal) or by users at a terminal without tying up the terminal.

The init daemon is the system and service manager for RHEL. It is one of the first processes RHEL

starts when it boots. It has a PID of 1 and is the ancestor of all processes. On RHEL, services are

started and stopped through init scripts in the /etc/init.d directory. Many of these services

are launched by the init daemon when the system is booted.

Many System V UNIX variants use scripts in the /etc/rcN.d/ directories to control which services

should be started in the various run levels. Since this model involved having multiple copies of the

same script in many different directories, RHEL adopted the standard of putting all service control

scripts in the /etc/init.d/ directory and using symbolic links to these scripts in the various
