1、准备三台服务，ip如下
192.168.37.183192.168.37.150192.168.37.86
2、防火墙
zookeeper服务应限制访问ip，将集群节点和需要访问zookeeper的ip添加到trusted区域
安装、启动防火墙
yum install firewalld.noarchsystemctl enable firewalld.servicesystemctl start firewalld.service
不同的服务器执行不同的命令
（1）192.168.37.183服务器
firewall-offline-cmd --zone=trusted --add-source=192.168.37.150firewall-offline-cmd --zone=trusted --add-source=192.168.37.86systemctl reload firewalldfirewall-cmd --list-all-zones
（2）192.168.37.150服务器
firewall-offline-cmd --zone=trusted --add-source=192.168.37.183firewall-offline-cmd --zone=trusted --add-source=192.168.37.86systemctl reload firewalldfirewall-cmd --list-all-zones
（3）192.168.37.86服务器
firewall-offline-cmd --zone=trusted --add-source=192.168.37.183firewall-offline-cmd --zone=trusted --add-source=192.168.37.150systemctl reload firewalldfirewall-cmd --list-all-zones
3、zookeeper集群搭建
新建zookeeper数据目录
mkdir /home/trimps/zoodata
不同的服务器执行不同的命令
（1）192.168.37.183服务器
echo "1" > /home/trimps/zoodata/myid
（2）192.168.37.150服务器
echo "2" > /home/trimps/zoodata/myid
（3）192.168.37.86服务器
echo "3" > /home/trimps/zoodata/myid
将apache-zookeeper-3.7.0-bin.tar.gz文件上传到/home/trimps/software目录，解压
tar -zxvf apache-zookeeper-3.7.0-bin.tar.gz
主要配置（各服务器配置相同）
vi zoo.cfgtickTime=2000initLimit=10syncLimit=5dataDir=/home/trimps/zoodataclientPort=3292server.1=192.168.37.183:3999:4999server.2=192.168.37.150:3999:4999server.3=192.168.37.86:3999:4999
启动、查看状态、停止命令
bin/zkServer.sh startbin/zkServer.sh statusbin/zkServer.sh stop
4、查看状态
（1）192.168.37.183服务器
[root@0003 apache-zookeeper-3.7.0-bin]# bin/zkServer.sh statusZooKeeper JMX enabled by defaultUsing config: /home/trimps/software/apache-zookeeper-3.7.0-bin/bin/../conf/zoo.cfgClient port found: 3292、Client address: localhost、Client SSL: false.Mode: follower

5、测试
客户端连接192.168.37.183服务器并新建一个节点，客户端连接192.168.37.183、192.168.37.150、192.168.37.86服务器并查看节点信息
