zookeeper3.4.10集群方式安装
# 安装
本次将zookeeper安装至/usr/local/hadoop/zookeeper-3.4.10/目录下
下载：
zookeeper3.4.10下载 (opens new window)
linux环境准备：
注意：准备服务器台数的时候要注意，一定要是奇数（1，3，5，7台机器）
| 序号 | IP | hostname |
|---|---|---|
| 1 | 192.168.56.121 | mini1 |
| 2 | 192.168.56.122 | mini2 |
| 3 | 192.168.56.123 | mini3 |
# 上传并解压zookeeper-3.4.10包
[root@mini1 soft]# tar -zxvf zookeeper-3.4.10.tar.gz

# 配置zookeeper
修改zoo.cfg文件
[root@mini1 soft]# cd /usr/local/hadoop/zookeeper-3.4.10/conf/
# 复制一份zoo.cfg配置文件
[root@mini1 conf]# cp zoo_sample.cfg zoo.cfg
# 配置zoo.cfg
[root@mini1 conf]# vi zoo.cfg

zoo.cfg配置文件如下：中文的地方需要修改
# 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 <span style='color:red;'>需要修改，自行创建zkdata目录</span>
dataDir=/usr/local/hadoop/zookeeper-3.4.10/zkdata
# 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
# <span style='color:red;'>这里的机器台数一定要是奇数</span>

创建节点myid文件
# 创建/usr/local/hadoop/zookeeper-3.4.10/zkdata目录
[root@mini1 conf]# mkdir /usr/local/hadoop/zookeeper-3.4.10/zkdata
[root@mini1 conf]# cd /usr/local/hadoop/zookeeper-3.4.10/zkdata
[root@mini1 zkdata]# echo 1 >myid

# 在mini2和mini3上安装zookeeper
使用scp命令将mini1上配置的zookeeper复制到mini2和mini3机器上
[root@mini1 conf]# scp -r /usr/local/hadoop/ mini2:/usr/local/
[root@mini1 conf]# scp -r /usr/local/hadoop/ mini3:/usr/local/

修改mini2上的myid文件内容为2
修改mini3上的myid文件内容为3
# 启动zookeeper集群
分别在三台机器上执行zkServer.sh start命令
[root@mini1 conf]# zkServer.sh start
