Linux中zookeeper的安装

• 关闭防火墙

  systemctl stop firewalld  
  systemctl disable firewalld 
  

• 下载安装包、解压

  tar -zxvf zookeeper-3.4.6.tar.gz
  mv zookeeper-3.4.6 zookeeper
  

• 修改环境变量，可选操作

  vi /etc/profile
  

  export ZOOKEEPER_HOME=/export/server/zookeeper export
  PATH=$PATH:$ZOOKEEPER_HOME/bin
  

  source /etc/profile
  

• 修改Zookeeper配置文件

  cd zookeeper/conf
  mv zoo_sample.cfg zoo.cfg
  

  vi zoo.cfg
  

  dataDir=/export/data/zkdata
  server.1=node1:2888:3888
  server.2=node2:2888:3888
  server.3=node3:2888:3888
  

• 创建文件夹：

  mkdir -p /export/data/zkdata
  

• 在data文件夹下新建myid文件，myid的文件内容为对应服务器编号：

  echo 1 > /export/data/zkdata/myid 
  

• 分发安装包到其他机器

  cd /export/server
  scp -r zookeeper/ root@node2:$PWD
  scp -r zookeeper/ root@node3:$PWD
  

• 修改myid文件

  mkdir -p /export/data/zkdata
  echo 2 > /export/data/zkdata/myid  
  mkdir -p /export/data/zkdata
  echo 3 > /export/data/zkdata/myid  
  

/export/server/zookeeper/bin/zkServer.sh  start|stop|status

#!/bin/bash
hosts=(node1 node2 node3)
for host in ${hosts[*]}
do
 ssh $host "source /etc/profile;/export/server/zookeeper/bin/zkServer.sh start"
done

#!/bin/bash
hosts=(node1 node2 node3)
for host in ${hosts[*]}
do
 ssh $host "/export/server/zookeeper/bin/zkServer.sh stop"
done

• 查看进程

  jps
  

• 查看集群状态，主从信息

  zkServer.sh status
