  1. Solved the problem.

    Go to line 122 in /etc/init.d/jenkins

    Replace $SU -l $JENKINS_USER --shell=/bin/bash -c "$DAEMON $DAEMON_ARGS -- $JAVA $JAVA_ARGS -jar $JENKINS_WAR $JENKINS_ARGS" || return 2

    To $SU -l $JENKINS_USER --shell=/bin/bash -c "$DAEMON $DAEMON_ARGS -- $JAVA $JAVA_ARGS -jar $JENKINS_WAR $JENKINS_ARGS --ajp13Port=-1" || return 2
