安装zookeeper

1. 下载
链接：

 http://zookeeper.apache.org/releases.html
 https://archive.apache.org/dist/zookeeper/

2. 上传
通过 MobaXterm stfp功能
上传文件到 /opt/pkg3. 解压
三台机器都需要安装，配置

 tar -zxvf zookeeper-3.4.6.tar.gz -C /opt/software/       --解压到指定路径

4. 配置文件

  cd /opt/software/zookeeper-3.4.6/conf
  cp zoo_sample.cfg zoo.cfg

vi zoo.cfg

clientPort=2181
dataDir=/opt/software/zookeeper/data
dataLogDir=/opt/software/zookeeper/logs

server.1=0.0.0.0:2881:3881                   --阿里云 本机都配置0.0.0.0 其他两台机器，就是ip
server.2=cdh02:2881:3881
server.3=cdh03:2881:3881

第二台机器

 
clientPort=2181
dataDir=/opt/software/zookeeper/data
dataLogDir=/opt/software/zookeeper/logs

server.1=cdh01:2881:3881
server.2=0.0.0.0:2881:3881
server.3=cdh03:2881:3881

第三台机器

clientPort=2181
dataDir=/opt/software/zookeeper/data
dataLogDir=/opt/software/zookeeper/logs

server.1=cdh01:2881:3881
server.2=cdh02:2881:3881
server.3=0.0.0.0:2881:3881

5.创建数据存放目录，并创建myid文件

mkdir -p /opt/software/zookeeper/data
mkdir -p /opt/software/zookeeper/logs

 cd /opt/software/zookeeper/data/
 echo 1 > myid

 echo 2 > myid --其他两台分别是2 和 3
 echo 3 > myid --其他两台分别是2 和 3

6. 配置环境变量

vim /etc/profile.d/my_env.sh 

export ZOOKEEPER_HOME=/opt/software/zookeeper-3.4.6
export PATH=$PATH:$ZOOKEEPER_HOME/bin

source /etc/profile.d/my_env.sh          --刷新

7.启动

三台依次启动

cd /opt/software/zookeeper-3.4.6/
 bin/zkServer.sh start

查看状态

bin/zkServer.sh status
