Got two RHEL servers - one real and one virtual/cloud.
Both run apache web server.
When traffic is applied, CPU seems to go quite high on virtual one (20%) but real is not really affected. Worry is that a further increase in traffic will see a problem.
Experience of RHEL is limited. Whats... (2 Replies)

pidfilehack
pidfilehack(8) System Manager's Manual pidfilehack(8)NAME
pidfilehack - work around daemons that always fork
SYNOPSIS
pidfilehack servicename pidfile command [parameters]
DESCRIPTION
pidfilehack is used to work around daemons that insist on forking into the background, but that do write a correct pid file.
pidfilehack forks the actual service, then waits for the pidfile to be written. Once it can read the pid from the pidfile it will tell
minit the real pid and quit.
USAGE
usually pidfilehack is symlinked as run command of a service.
servicename
the name of the service pidfilehack is installed for.
pidfile
the filename to read the pid from
command
the real command to start
parameters
additional parameters for the command
A typical use of this command will look like this:
/etc/minit/apache
/etc/minit/apache/params
apache
/var/run/apache.pid
apachectl
start
/etc/minit/apache/run
-> /sbin/pidfilehack
