6 Docker——Zookeeper 3.7.0 环境搭建

1 下载

https://apache.website-solution.net/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz

2 安装

tar -zxvf /software/apache-zookeeper-3.7.0-bin.tar.gz -C /usr/local/

3 重命名

mv /usr/local/apache-zookeeper-3.7.0-bin/ /usr/local/zookeeper

4 创建文件夹

mkdir /usr/local/zookeeper/data

5 修改master配置文件

复制配置文件模板

cp /usr/local/zookeeper/conf/zoo_sample.cfg /usr/local/zookeeper/conf/zoo.cfg

修改配置文件

vim /usr/local/zookeeper/conf/zoo.cfg

更改

dataDir=/usr/local/zookeeper/data

添加如下内容

server.1=master:2888:3888
server.2=slave01:2888:3888
server.3=slave02:2888:3888

6 复制到各个子节点

scp -r /usr/local/zookeeper slave01:/usr/local
scp -r /usr/local/zookeeper slave02:/usr/local

7 创建myid文件
master节点添加myid文件

touch /usr/local/zookeeper/data/myid

echo 1 > /usr/local/zookeeper/data/myid

slave1节点添加myid文件

touch /usr/local/zookeeper/data/myid

echo 2 > /usr/local/zookeeper/data/myid

slave2节点添加myid文件

touch /usr/local/zookeeper/data/myid

echo 3 > /usr/local/zookeeper/data/myid

8 启动zookeeper（master、slave1、slave2均需执行）
启动master

cd /usr/local/zookeeper/bin

./zkServer.sh start

使用 ./zkServer.sh start-foreground 可显示错误
