原因调查：

root@ubuntu:/home/wqxin01/zookeeper-3.4.6/bin# cat zookeeper.out 

（注意目录和文件名）

原来在 zoo.cfg文件中配置：dataLogDir=/home/wqxin01/zookeeper-3.4.6/logs  文件夹不存在。
所以只能手动建：

root@ubuntu:/home/wqxin01/zookeeper-3.4.6#  mkdir logs

然后重启zookeeper

root@ubuntu:/home/wqxin01/zookeeper-3.4.6/bin# zkServer.sh  stop
root@ubuntu:/home/wqxin01/zookeeper-3.4.6/bin# zkServer.sh  start
