  groupadd -g 333 ossec
  useradd  -u 333 -g 333 -d /var/ossec -s /bin/false ossec
  useradd  -u 334 -g 333 -d /var/ossec -s /bin/false ossecm

You may wish to add these lines to /etc/rc.d/rc.local to start the service:

if [ -x /etc/rc.d/rc.ossec ]; then
  /etc/rc.d/rc.ossec start
fi

You may also add these lines to /etc/rc.d/rc.local_shutdown:

if [ -x /etc/rc.d/rc.ossec ]; then
  /etc/rc.d/rc.ossec stop
fi

Remember to give executable permission to /etc/rc.d/rc.local_shutdown:

  chmod 0755 /etc/rc.d/rc.local_shutdown
