本文主要是介绍linux下安装zookeeper-3.6.1并解决启动报错问题，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

linux下安装Zookeeper

单机版

①创建安装目录

mkdir -p /usr/local/zookeeper

②将tar包解决到安装目录下

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local/zookeeper/

③创建数据目录data，日志目录log

mkdir -p /usr/local/zookeeper/apache-zookeeper-3.6.1-bin/data mkdir -p /usr/local/zookeeper/apache-zookeeper-3.6.1-bin/log

④修改配置文件(conf目录)，默认启动配置文件为zoo.cfg

（复制zoo_sample.cfg一份修改名称为zoo.cfg）

# 进入配置文件
cd /user/local/zookeeper/apache-zookeeper-3.6.1-bin/conf/
# zookeeper 启动默认加载名为 zoo.cfg的配置文件，所以复制一份命名为 zoo.cfg
cp zoo_sample.cfg zoo.cfg
# 修改配置文件
vim zoo.cfg

⑤配置dataDir和dataLogdir

# 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=/usr/local/zookeeper/apache-zookeeper-3.6.1-bin/data
dataLogDir=/usr/local/zookeeper/apache-zookeeper-3.6.1-bin/log
# 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

## Metrics Providers

在bin目录下启动zookeeper

./zkServer.sh start

• 可以直接通过bin目录下的zkcli.sh进行连接

  ./zkCli.sh

  下图为连接成功
  

客户端连接成功后可以进行的操作指令

• ls /

集群版

创建解压目录

①先创建一个目录

mkdir -p /usr/local/zookeeper/zk1

②将文件解压到该目录

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local/zookeeper/zk1/

③创建data目录和log目录，data目录下添加myid文件，myid中只写一个1就行

mkdir /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data

mkdir /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/log

cd /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data

vim myid

• 复制zoo_sample.cfg，并将文件重命名为zoo.cfg

  cp zoo_sample.cfg zoo.cfg
  

• 修改zk1配置的zoo.cfg

  vim zoo.cfg

  dataDir=/usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data
  dataLogDir=/usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/log
  
  

  # 集群配置
  # server.1中的1是myid文件中的内容，2888,2889,2890用于集群内部通信，3888,3889，3890用于选择leader
  server.1=192.168.152.100:2888:3888
  server.2=192.168.152.100:2889:3889
  server.3=192.168.152.100:2890:3890
  
  

  

• 将zk1文件夹复制两份为zk2/zk3

  cd /usr/local/zookeeper/

  cp -Rf zk1/ zk2

  cp -Rf zk1/ zk3

• 修改zk2的配置文件zoo.cfg

  dataDir=/usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/data
  dataLogDir=/usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/log
  
  clientPort=2182
  

  修改zk2中data目录下的myid文件 —把1改成2

  cd /usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/data

  vim myid

  把1改成2 (同理在zk3中把myid改成3)

  • 注意:这里的myid和配置文件中有关
    

    如果没有改可能会出现以下错误

• 修改zk3的配置文件zoo.cfg（和zk2相似）

  dataDir=/usr/local/zookeeper/zk3/apache-zookeeper-3.6.1-bin/data
  dataLogDir=/usr/local/zookeeper/zk3/apache-zookeeper-3.6.1-bin/log
  
  clientPort=2183
  

• 启动

  注意：这里需要把三台**全部启动，再查看状态**

    	原因：涉及到Leader（Master）选举的问题
  

  cd /usr/local/zookeeper/
  
  zk1/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start
  
  zk2/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start
  
  zk3/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start
  

• 查看状态

  cd /usr/local/zookeeper/
  
  zk1/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status
  
  zk2/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status
  
  zk3/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status
