CentOS 7 安装Apache-Zookeeper-3.6.2

Apache-Zookeeper-3.6.2的安装

简介

• 本文主要介绍Centos 7下安装简单的zookeeper集群

1 Zookeeper下载地址

2 安装并配置Zookeeper

2.1 安装zookeeper

tar -zxvf apache-zookeeper-3.6.2-bin.tar.gz -C /opt/module/
cd /opt/module/
mv apache-zookeeper-3.6.2-bin/ zookeeper-2.6.2
           

2.2 配置zookeeper集群

cd  zookeeper-2.6.2/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

#将文件下添加如下内容
tickTime=2000
#zk的存放数据的目录,可以指定在zk的home目录下创建一个data目录
dataDir=/opt/module/zookeeper-3.6.2/data
#客户端访问端口
clientPort=2181
initLimit=5
syncLimit=2
#server.id=ip:port:port，id应该与data/下的myid中的内容保持一致
server.1=shufang101:2888:3888
server.2=shufang102:2888:3888
server.3=shufang103:2888:3888
           

2.3 分发zookeeper的目录到其它节点

cd /opt/module
xsync zookeeper-3.6.2
           

2.4 在各个节点上分别创建data目录，创建myid文件

# shufang101
cd /opt/module/zookeeper-3.6.2
mkdir data
cd data/
touch myid
echo 1 > myid
-------------
# shufang102
cd /opt/module/zookeeper-3.6.2
mkdir data
cd data/
touch myid
echo 2 > myid
--------------
# shufang103
cd /opt/module/zookeeper-3.6.2
mkdir data
cd data/
touch myid
echo 3 > myid
           

2.5 分别在不同节点上启动zkServer.sh start

• 分别在shufang101 shufang102 shufang103上启动 zkServer.sh start /status/stop

3 群起脚本

# 1 首先必须在~/.bashrc 下配置JAVA_HOME，否则会报错
cat /etc/profile >> ~/.bashrc 
source ~/.bashrc 
# 2 
cd ~/bin

vim zkall
chmod 777 zkall 
-------------------------
#!/bin/bash
for i in [email protected] [email protected] [email protected]
do 
        echo "---------------------- $i-------------------------";

        ssh $i /opt/module/zookeeper-3.6.2/bin/zkServer.sh start
done
