Fresh installation of zookeeper does not survive a reboot

Commands run:

• yum install hadoop-zookeeper-server.noarch hadoop-hbase-master.noarch hadoop-hbase-regionserver.noarch hadoop-hbase-thrift.noarch hadoop-hive.noarch hadoop-pig.noarch hadoop-0.20-sbin.x86_64 hadoop-0.20-sbin.i386 hadoop-0.20-pipes.x86_64 hadoop-0.20-native.x86_64 hadoop-0.20-libhdfs.x86_64 hadoop-0.20-fuse.x86_64 hadoop-0.20-doc.noarch hadoop-0.20-debuginfo.x86_64 flume sqoop hue
• reboot

• [root@localhost ~]# service hadoop-zookeeper status
  ZooKeeper is not running.

Here are the logs suggesting this is a port conflict somewhere:
