Zookeeper简单应用（单机）

简单的zookeeper单机安装部署，类似安装部署手册吧~

以sthe账户为例安装zookeeper

1. zookeeper安装包zookeeper-3.4.6.tar.gz上传至home目录下。（rz 命令 或者 secureFX工具）

2. 解压安装包

3. 配置文件修改

[sthe@server conf]$ vi zoo.cfg 
# The number of milliseconds of each tick
# tickTime：这个时间是作为Zookeeper服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个tickTime时间就会发送一个心跳。

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：Zookeeper保存数据的目录，默认情况下，Zookeeper将写数据的日志文件也保存在这个目录里。

#dataDir=/tmp/zookeeper 这个是默认的

dataDir=/home/sthe/zookeeper-3.4.6/data
# the port at which the clients will connect

#clientPort：这个端口就是客户端连接Zookeeper服务器的端口，Zookeeper会监听这个端口，接受客户端的访问请求。

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

保存退出配置就完了

启动：cd /home/sthe/zookeeper-3.4.6/bin 执行 ./zkServer.sh start 

状态：./zkServer.sh status

关闭：./zkServer.sh stop
