PROSAGA码农传奇-zookeeper-zookeeper中的“ java.net.ConnectException：连接被拒绝”

我按以下方式安装了zookeeper： <code>
wget http://archive.cloudera.com/cdh/3/zookeeper-3.3.3-cdh3u1.tar.gz
</code> 这是我的zoo.cf：
<pre><code># The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/home/reach121/basf/data/zookeeper/data1
# maximum client connection
maxClientCnxns=500
# the port at which the clients will connect
clientPort=2183
server.1=localhost:2878:3878
server.2=localhost:2879:3879
server.3=localhost:2880:3880
</code></pre>然后开始 <code>
/bin/zkServer.sh start zoo.cfg
</code> 当我做什么？ <code>
bin/zkCli.sh -server 127.0.0.1:2183
</code> 它给了我这个错误：
