After installing jenkins without receiving any error messages, then starting jenkins from the command line, no log file is created and jenkins is not listening on the assigned port. There is no error in any server log.

Steps to repeat

wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo

rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

yum install jenkins

Changed the 2 below ports after confirming they were free.
vi /etc/sysconfig/jenkins
JENKINS_AJP_PORT="8007"
JENKINS_AJP_PORT="-1"

service jenkins start - server responded with, "OK"

service jenkins status - server responded with, "jenkins dead but pid file exists"

During installation /var/log/jenkins directory was created with owner and group of jenkins. No log file created.

Created from yum install

/var/log/jenkins
/var/run/jenkins.pid
/var/lib/jenkins
/usr/lib/jenkins
/usr/lib/jenkins/jenkins.war
/usr/sbin/rcjenkins
/var/cache/jenkins
/etc/logrotate.d/jenkins
/etc/rc.d/init.d/jenkins
/etc/sysconfig/jenkins

vi /etc/passwd - shows the below line

jenkins:x:496:494:Jenkins Continuous Build server:/var/lib/jenkins:/bin/false

java -version
java version "1.6.0_30"

Also tried using java version 1.7 but experienced the same results.
