windows下zookeeper伪集群搭建以及遇到myid文件找不到

1.下载zookeeper压缩包，解压到三个不同文件夹

zookeeper1、zookeeper2、zookeeper3文件夹打开后如下：

2.找到conf文件下的zoo_sample.cfg，复制后改名称为zoo.cfg

3.配置zoo.cfg（注意双斜杠，本机测试不加双斜杠提示找不到myid路径，因为myid存放在data文件夹下）

zookeeper1的配置：

#dataDir=/tmp/zookeeper
dataDir=C:\\zookfk\\zk_cluster\\zookeeper1\\data
dataLogDir=C:\\zookfk\\zk_cluster\\zookeeper1\\log
# the port at which the clients will connect
clientPort=2181
server.1=127.0.0.1:2016:2006
server.2=127.0.0.1:2017:2007
server.3=127.0.0.1:2018:2008

zookeeper2的配置：

#dataDir=/tmp/zookeeper
dataDir=C:\\zookfk\\zk_cluster\\zookeeper2\\data
dataLogDir=C:\\zookfk\\zk_cluster\\zookeeper2\\log
# the port at which the clients will connect
clientPort=2182
server.1=127.0.0.1:2016:2006
server.2=127.0.0.1:2017:2007
server.3=127.0.0.1:2018:2008

zookeeper3的配置：

#dataDir=/tmp/zookeeper
dataDir=C:\\zookfk\\zk_cluster\\zookeeper3\\data
dataLogDir=C:\\zookfk\\zk_cluster\\zookeeper3\\log
# the port at which the clients will connect
clientPort=2183
server.1=127.0.0.1:2016:2006
server.2=127.0.0.1:2017:2007
server.3=127.0.0.1:2018:2008

4.data文件下创建myid文件

myid文件没有后缀，直接创建名字myid，内容分别为server后的数字1、 2 、 3

5.启动zookeeper

分别切换到三个zookeeper目录下的bin目录，cmd输入zkServer.cmd或者点击zkServer.cmd，启动时会报错如下：

2018-07-27 13:11:33,711 [myid:1] - WARN  [WorkerSender[myid=1]:QuorumCnxManager@382] - Cannot open channel to 3 at election address /127.0.0.1:2008

        at java.lang.Thread.run(Thread.java:748)

原因：zookeeper的其他节点还没有启动，当三个节点都启动后，就正常运行了。

6.检测zookeeper是否启动，jps

QuorumPeerMain是zookeeper启动类，有这个进程就表示启动成功
