shell脚本搭建zookeeper错误提醒：Error contacting service. It is probably not running.

shell脚本搭建zk错误记录

网上的正常配置：

1. shell脚本
   在/usr/local/bin下面创建一个shell程序，命名为start.sh。

#!/bin/bash
echo "==========          zookeeper启动                                     =========="
echo "==========          正在启动zookeeper                                 =========="
for i in donghao@hadoop132 donghao@hadoop133 donghao@hadoop134
do
        ssh $i '/opt/module/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start'
	sleep 2s
done

echo "==========          正在启动HDFS                                      =========="
ssh donghao@hadoop132 '/opt/module/hadoop/hadoop-2.7.3/sbin/start-dfs.sh'
echo "==========          正在启动YARN                                      =========="
ssh donghao@hadoop133 '/opt/module/hadoop/hadoop-2.7.3/sbin/start-yarn.sh'
echo "==========          hadoop132节点正在启动JobHistoryServer             =========="
ssh donghao@hadoop132 '/opt/module/hadoop/hadoop-2.7.3/sbin/mr-jobhistory-daemon.sh start historyserver'

2. zk的zoo.cfg设置
   在zk的conf文件包下，将此zoo.cfg文件修改如下

# 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.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/module/zookeeper/zookeeper-3.4.10/zkData
####################cluster####################

server.1=hadoop132:2888:3888

# the port at which the clients will connect

出现的问题

当我使用start.sh之后，

但是当我在我的hadoop134机器上查询zk服务器情况的时候出现以下情况

[donghao@hadoop133 zookeeper-3.4.10]$ bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/module/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

我使用自己编译的stop关闭zk的时候弹出

Using config: /opt/module/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg

显示的就是133与134的进程没有开启

问题查找

1. 我在我的hadoop132机器上

[donghao@hadoop132 bin]$ jps
23818 NodeManager
23499 DataNode
23936 JobHistoryServer
23316 NameNode
23065 QuorumPeerMain
24066 Jps

此处说明在hadoop132这台机器上，zkServer已经运行好了

2. 我在我的hadoop133机器上

[donghao@hadoop133 zookeeper-3.4.10]$ jps
25429 NodeManager
25142 DataNode
25773 Jps
25298 ResourceManager

此处说明在hadoop133机器上，zkServer未运行。

问题的解决

我查找了好多博客，之后解决了，我也不太清楚以下哪些是无用的，哪些才是关键的，但是我都在下面将我修改的列出来。

1. 首先修改conf文件夹下的zoo.cfg文件

# 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.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/module/zookeeper/zookeeper-3.4.10/zkData
####################cluster####################
#server.1=hadoop132:2888:3888
server.1=0.0.0.0:2888:3888   
#此处，如果是机器132上的zoo.cfg，此处将hadoop132修改成0.0.0.0，如果是133上面的就将hadoop133修改成0.0.0.0
server.2=hadoop133:2878:3878
server.3=hadoop134:2898:3898
#同时我将三个端口修改了一下，为了防止端口被占用情况的发生。（此处我不确定不修改有没有影响，我也没做过测试）


# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

2. 其次将zoo.cfg设定的dataDir文件夹下的myid
   此处将hadoop132机器上的myid修改成下面的参数值

[donghao@hadoop132 zkData]$ cat myid 
1

同时将hadoop133、hadoop134中的此值修改成对应的值（看zoo.cfg中的server后面的数值）

3. 修改shell程序
   我将shell程序进行了一定的修改，此处是我最后做的修改，作此修改以后我的shell运行成功，而且zk集群也运行起来了。

#!/bin/bash
echo "==========          zookeeper启动                                     =========="
echo "==========          正在启动zookeeper                                 =========="
for i in donghao@hadoop132 donghao@hadoop133 donghao@hadoop134
do
        ssh $i 'source /etc/profile;/opt/module/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start'
        #此处我添加了一个source /etc/profile;
	sleep 2s
done

echo "==========          正在启动HDFS                                      =========="
ssh donghao@hadoop132 '/opt/module/hadoop/hadoop-2.7.3/sbin/start-dfs.sh'
echo "==========          正在启动YARN                                      =========="
ssh donghao@hadoop133 '/opt/module/hadoop/hadoop-2.7.3/sbin/start-yarn.sh'
echo "==========          hadoop132节点正在启动JobHistoryServer             =========="
ssh donghao@hadoop132 '/opt/module/hadoop/hadoop-2.7.3/sbin/mr-jobhistory-daemon.sh start historyserver'

之后再运行，我在hadoop133上面就看到了

我自己也不太清楚，不过我这样的确成功了。
