Env(4) Zookeeper部署安装

参考文档：黑马06-zookeeper集群安装.doc

1 下载并解压

在node1上下载： Index of /zookeeper/stable（本文采用3.8.4）

tar -zxvf zookeeper.tar.gz -C .
ln -s apache-zookeeper-3.8.4-bin zookeeper

2 修改配置文件

cd zookeeper/conf
cp zoo_sample.cfg zoo.cfg
mkdir ../zkdata
sudo vim zoo.cfg

在zoo.cfg中：

# 第12行修改为：
dataDir=/home/user/Work/2025/zookeeper/zkdata
# 解除25和28行的注释：
autopurge.snapRetainCount=3
autopurge.purgeInterval=1
# 末尾添加：
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

4 配置myid

在node1上，在zkdata中创建名为”myid”的、内容为1的文件：

echo 1 > ../zkdata/myid

分发：

cd ../..
scp -r ./apache-zookeeper-3.8.4-bin node2:$PWD
scp -r ./apache-zookeeper-3.8.4-bin node3:$PWD

第2台机器上建立软连接, 并修改myid的值为2：

cd ./Work/2025
ln -s apache-zookeeper-3.8.4-bin/ zookeeper
echo 2 > zookeeper/zkdata/myid

第3台同理：

cd ./Work/2025
ln -s apache-zookeeper-3.8.4-bin/ zookeeper
echo 3 > zookeeper/zkdata/myid

5 启动服务

3台机器分别执行：

~/Work/2025/zookeeper/bin/zkServer.sh start

查看状态：

~/Work/2025/zookeeper/bin/zkServer.sh status

各节点状态如下：
