Overview
The lifecycle of the httpd server is controlled by sending Unix signals into the httpd parent process.
The signals can be sent into the parent process using the httpd process directly, using the -k command line option or (recommended) the apachectl control script.
For more details about the httpd server lifecycle see:
Use apachectl Control Script
This is the recommended method to control the httpd server life cycle.
apachectl -k stop|graceful|restart|graceful-stop
Send Signals Directly to httpd
httpd -TERM|-USR1|-HUP|-WINCH $(cat /usr/local/apache2/logs/httpd.pid)
Send Commands to httpd with -k Command Line Option
httpd -k stop|graceful|restart|graceful-stop
