检查ssh免密登录实现与否
[offcn@node-1 ~]$ ssh node-2
检查jdk的安装是否成功
[offcn@node-1 ~]$ java -version java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
检查时钟是否同步
三台机器统一执行date命令
1.安装包

提取码:zhxm
2、上传解压重命名:
cd /home/offcn/software/ tar -zxvf apache-zookeeper-3.5.7-bin.tar.gz -C ../apps/ cd /home/offcn/apps/ mv apache-zookeeper-3.5.7-bin zookeeper-3.5.7
3、创建zk数据存储目录:
cd /home/offcn/data/ mkdir zookeeper-3.5.7
4、创建myid
cd /home/offcn/data/zookeeper-3.5.7 echo 1 > myid
5、重命名配置文件:
cd /home/offcn/apps/zookeeper-3.5.7/conf/ mv zoo_sample.cfg zoo.cfg
6、修改核心配置文件
vim zoo.cfg
(1)指定数据存储目录
# the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/home/offcn/data/zookeeper-3.5.7/
(2)添加集群信息(节点、监听端口、选举端口)
server.1=node-1:2888:3888 server.2=node-2:2888:3888 server.3=node-3:2888:3888
zk端口说明:
2181:对clent端提供服务
2888:集群内机器通讯使用(Leader监听此端口)
3888:选举leader使用
(4)修改zk日志输出目录
cd /home/offcn/apps/zookeeper-3.5.7/bin vim zkEnv.sh if [ "x${ZOO_LOG_DIR}" = "x" ] then # ZOO_LOG_DIR="$ZOOKEEPER_PREFIX/logs" ZOO_LOG_DIR="$HOME/logs/zookeeper-3.5.7/" fi
(5)分发安装包以及修改myid
cd /home/offcn/apps/ scp -r zookeeper-3.5.7/ node-2:$PWD scp -r zookeeper-3.5.7/ node-3:$PWD cd /home/offcn/data/ scp -r zookeeper-3.5.7/ node-2:$PWD scp -r zookeeper-3.5.7/ node-3:$PWD
注意:修改node-2、node-3的myid
(6)修改环境变量(可选)
sudo vim /etc/profile
#zookeeper-3.5.7 export ZOOKEEPER_HOME=/home/offcn/apps/zookeeper-3.5.7 export PATH=$PATH:$ZOOKEEPER_HOME/bin
同步环境变量到其他节点
sudo scp /etc/profile node-2:/etc sudo scp /etc/profile node-3:/etc
三台机器全部执行
source /etc/profile(三)服务启停
1、服务端启停
zkServer.sh start zkServer.sh stop zkServer.sh status
2、客户端启停
zkCli.sh
3、一键启停脚本
cd mkdir bin vim zk.sh chmod 777 zk.sh
zk.sh
#!/bin/bash echo -e "e[1;35m Zookeeper $1 .... e[0m" export scriptsPath=`pwd` for host in node-1 node-2 node-3 do echo "===================$host $1=====================" if [ $1 = status ] then ssh $host "source /etc/profile;zkServer.sh $1" | grep "Mode" elif [ $1 = restart ] then sh $scriptsPath/$0 stop;sleep 3;sh $scriptsPath/$0 start;break else ssh $host "source /etc/profile;nohup zkServer.sh $1>/dev/null 2>&1 &" fi done
最后启动结果
