Zookeeper启动报错

我在三台机器上部署了zookeeper,启动的时候报错了，部署步骤如下：
1、在conf目录下创建 zoo.cfg
 
tickTime=2000
dataDir=/usr/local/zookeeper/data 
dataLogDir=/usr/local/zookeeper/dataLog
clientPort=2181
initLimit=5
syncLimit=2
server.1=liullei-1:2888:3888
server.2=liulei-2:2888:3888
server.3=liulei-3:2888:3888
 
 复制这个文件到另外两台机器的conf目录下
3、修改主机liulei-1中的zoo.cfg中的两个配置：
peerType=observer
server.1:localhost:2181:3181:observer
4、在每一台机器的dataDir=/usr/local/zookeeper/data  下新建一个文件myid,内容分别为：1、2、3
