Zookeeper安装与配置 - 图1

linux的环境

  • jdk1.8
  • tomcat：9.0
  • zookeeper 3.5.6

3 安装与配置

3.1 新建解压目录

在linux的opt新建ZooKeeper目录

  1. cd /opt/ZooKeeper
  3. #上传zookeeper alt+p
  4. put f:/setup/apache-zookeeper-3.5.6-bin.tar.gz
  5. #打开 opt目录
  6. cd /opt
  7. #创建zooKeeper目录
  8. mkdir  zooKeeper
  9. #将zookeeper安装包移动到 /opt/zooKeeper
  10. mv apache-zookeeper-3.5.6-bin.tar.gz /opt/zookeeper/![点击并拖拽以移动](data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==)

3.2 解压压缩包

  1. tar -zxvf apache-ZooKeeper-3.5.6-bin.tar.gz ![点击并拖拽以移动](data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==)

3.3 配置zoo.cfg

  1. #进入到conf目录
  2. cd /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/conf/
  3. #拷贝
  4. cp  zoo_sample.cfg  zoo.cfg![点击并拖拽以移动](data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==)

3.4 修改zoo.cfg

  1. #打开目录
  2. cd /opt/zooKeeper/
  3. #创建zooKeeper存储目录
  4. mkdir  zkdata
  5. #修改zoo.cfg
  6. vim /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/conf/zoo.cfg

Zookeeper安装与配置 - 图2

修改存储目录：dataDir=/opt/zookeeper/zkdata

修改端口占用：admin.serverPort=9091 (原因：默认8080端口和tomcat端口占用)

3.5 启动ZooKeeper

输入 cd /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/bin/

输入 ./zkServer.sh start

  1. cd /opt/zooKeeper/apache-zooKeeper-3.5.6-bin/bin/
  2. #启动 
  3. ./zkServer.sh  start
  4. ZooKeeper JMX enabled by default
  5. Using config: /opt/zooKeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
  6. ZooKeeper JMX enabled by default
  7. Using config: /opt/zooKeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
  8. Stopping zookeeper ... ./zkServer.sh: 第 213 行:kill: (30207) - 没有那个进程
  9. STOPPED
  10. ZooKeeper JMX enabled by default
  11. Using config: /opt/zooKeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
  12. Starting zookeeper ... STARTED

3.6 查看ZooKeeper状态

输入 ./zkServer.sh status

  1. ./zkServer.sh status
  2. ZooKeeper JMX enabled by default
  3. Using config: /opt/zooKeeper/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
  4. Client port found: 2181. Client address: localhost.
  5. Mode: standalone

standalone代表zk没有搭建集群，现在是单节点 ，端口：2181
