前几段的时候，Zookeeper的安装是成功的，也启动成功，但是今天不知道就怎么了，另外一台装突然就一直启动不起来。在‘#’后面的是注释：

# 目前所在的位置：

[scidb@localhost bin]$ pwd

/home/scidb/zookeeper/zookeeper-3.4.8/bin

# 在bin的文件下有这些文件：

[scidb@localhost bin]$ ls

README.txt zkCli.cmd zkEnv.cmd zkServer.cmd zookeeper.out

zkCleanup.sh zkCli.sh zkEnv.sh zkServer.sh

# 接下来启动 zkServer.sh

[scidb@localhost bin]$ sudo sh zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /home/scidb/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg

Starting zookeeper … STARTED

# 看起来是启动成功了哦，然后我们再来看看是否真的启动成功了。

[scidb@localhost bin]$ sh zkServer.sh status

ZooKeeper JMX enabled by default

Using config: /home/scidb/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg

Error contacting service. It is probably not running.

# 呵呵，居然没有启动起来。然后我用zkCli.sh 尝试启动客户端，结果。。

# 乍一看配置没错啊，我想看看到底2181端口是否被占用。

[scidb@localhost bin]$ sudo netstat -anp | grep 2181

# 命令没有问题，程序是真的没有启动起来。

# 接下来我在google和百度里看了搜索了许多有关于这个错误的信息。

分别搜索了‘at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1141)’、

‘at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:361)

’、‘INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@1032] - Opening socket connection to server localhost/0:0:0:0:0:0:0:1:2181. Will not attempt to authenticate using SASL (unknown error)’……

看了很多在http://stackoverflow.com/ 上的回答。。。

我靠，居然都没有用啊，多数都在强调你的配置文件的问题。但是配置都已经看烂了，没有什么问题啊！！！

# 好吧，最后我快绝望的我切换成root用户，然后象征性的启动，然后查看状态。
