zookeeper集群部署（伪集群，版本号zookeeper-3.4.10）

在虚拟机上进行伪集群部署，部署一个节点，拷贝两个，完成三个节点的部署

1，zookeeper下载，下载zookeeper安装包，并解压

2，进入zookeeper的conf目录下，对文件zoo_sample.cfg进行重命名为zoo.cfg，并进行如下编辑：

# 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=/srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data
dataLogDir=/srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data/log
# the port at which the clients will connect
clientPort=2281
# 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
server.1=10.1.88.101:2188:3188
server.2=10.1.88.101:2288:3288
server.3=10.1.88.101:2388:3388

主要是对 dataDir 数据目录，dataLogDir日志目录，clientPort端口号等参数进行目录设置，并设置server1,2,3的IP及通信端口。

3，进入zookeeper的data目录下，对myid文件进行编辑，直接在myid文件中写入1即可，id值与zoo.cfg中的server.*是对应的，  server.1的myid文件，就写入1。其他节点就是对应的2,3。如果没有myid文件，就执行下述命令创建并写入。

echo 1 > /srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data/myid

4，复制配置好的server1，粘贴为server2，server3，并更改相应zoo.cfg的端口为2282myid为2，端口为2283的myid为3。
