zookeeper集群搭建

1.关闭防火墙

查看防火墙状态
firewall-cmd --state
关闭防火墙
systemctl stop firewalld.service 
开机禁用
sysemctl disable firewalld.service

2.下载zookeeper3.4.6

http://archive.apache.org/dist/zookeeper/

3.zookeeper安装

tar zxvf zookeeper-3.4.6.tar.gz 
cd zookeeper-3.4.6
cp conf/zoo_sample.cfg conf/zoo.cfg
#把zookeeper加入到环境变量
echo -e "# append zk_env
export PATH=$PATH:/opt/soft/zookeeper-3.4.6/bin" >> /etc/profile
source /etc/profile

4.集群配置

#修改过后的配置文件zoo.cfg，如下：

tickTime=2000
initLimit=10
syncLimit=5
dataLogDir=/opt/soft/zookeeper-3.4.6/logs
dataDir=/opt/soft/zookeeper-3.4.6/data
clientPort=2181
autopurge.snapRetainCount=500
autopurge.purgeInterval=24
server.1= 192.168.231.128:2888:3888
server.2=  192.168.231.129:2888:3888
server.3=  192.168.231.130:2888:3888

#创建相关目录，三台节点都需要

mkdir -p /opt/soft/zookeeper-3.4.6/{logs,data}

创建myid文件

echo "1">>/opt/soft/zookeeper-3.4.6/data/myid

把zookeeper发送到其他服务器

scp -r zookeeper-3.4.6 root@zto2:$PWD

scp -r zookeeper-3.4.6 root@zto3:$PWD

修改对应的myid

启动zookeeper server:
./zkServer.sh start
查看zookeeper状态
./zkServer.sh status
进客户端
./zkCli.sh -server 192.168.231.130:2181
