1.	Solve : chkconfig [service name] not displaying any return values.?
Answer» In the chkconfig man page --> " When chkconfig is run with only a service name, it CHECKS to see if the service is configured to be STARTED in the current runlevel. If it is, chkconfig returns true; OTHERWISE it returns false. " But when I execute chkconfig HTTPD , there is no output. https://access.redhat.com/site/documentation//en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-services-chkconfig.html chkconfig --list httpd should WORK if httpd service is installed to enable/disable on/off
