二、Zookeeper搭建

1. 安装包解压指定地点
2. 配置环境变量
3. 修改默认配置

mkdir /usr/zookeeper
cd /usr/zookeeper
tar -zxvf /usr/package277/zookeeper-3.4.14.tar.gz -C /usr/zookeeper-3.4.14
cd zookeeper-3.4.14
pwd
vim /etc/profile
G
换行
#ZOOKEEPER
export ZOOKEEPER_HOME=/usr/zookeeper/cd zookeeper-3.4.14
export PATH=$PATH:ZOOKEEPER_HOME/bin
source /etc/profile
cd
cd conf/
vim zoo_sample.cfg

1. 设置数据存储路径

dataDir=/usr/zookeeper/cd zookeeper-3.4.14/zkdata

1. 设置日志文件路径
   dataLogDir=/usr/zookeeper/cd zookeeper-3.4.14/zkdatalog
2. 设置集群列表
   sever.1=master:2888:3888
   sever.2=slave1:2888:3888

sever.3=slave2:2888:3888

1. 创建所需文件夹
   cd /usr/zookeeper/cd zookeeper-3.4.14/
   mkdir zkdata zkdatalog
   scp -r /usr/zookeeper slave1:/usr/

scp -r /usr/zookeeper slave2:/usr/

1. 数据存储路径下创建myid
   echo 1 > /usr/zookeeper/cd zookeeper-3.4.14/zkdata/myid
   cat /usr/zookeeper/zookeeper-3.4.14/zkdata/myid
   slave1:

echo 2 > /usr/zookeeper/zookeeper-3.4.14/zkdata/myid
slave2:
echo 3 > /usr/zookeeper/zookeeper-3.4.14/zkdata/myid

1. 启动服务，查看进程QP
   zkSever.sh start
   zkSever.sh status
2. 查看各节点服务器角色是否正常
   jps
   如果寄了怎么办
   1. 停止服务
   2. 检查zoo.cfg
   3. 删除zkdata目录下除myid外所有文件
