Zookeeper3.7.1安装配置-526互联

前提条件

三台centos7的主机

hadoop集群搭建完毕

下载完拖到对应的目录下

#解压

sudo tar -zxvf apache-zookeeper-3.7.1-bin.tar.gz -C /usr/local/

#修改名称

sudo mv apache-zookeeper-3.7.1-bin zookeeper-3.7.1

#修改权限组

suod chown -R bill:freedom zookeeper-3.7.1

#到conf目录下修改zoo_sample.cfg为zoo.cfg

mv zoo_sample. cfg zoo.cfg

vi zoo.cfg

#修改配置

#下面文件目录可以自定义

dataDir=/mnt/data01/zk_data

#然后通过分发脚本在对应的另外两台主机上也部署zookeeper

sudo xsync /usr/local/zookeeper-3.7.1

sudo xsync chown -R bill:freedom /usr/local/zookeeper-3.7.1

xsync /mnt/data01/zk_data

#配置集群

cd /mnt/data01/zk_data

vi myid

#在里面第一行写上本主机的id

#分发脚本

xsync ../

#不同的主机id不一样,需要逐个修改，我这里设置的id为0，1，2

vi /usr/local/zookeeper-3.7.1/conf/zoo.cfg

#在末尾添加上这几行

server.0=billsaifu:2888:3888
server.1=hadoop1:2888:3888
server.2=hadoop2:2888:3888

xsync /usr/local/zookeeper-3.7.1/conf/zoo.cfg

最后重新配置一下hadoop的启动脚本

vi /home/bill/bin/myhadoop.sh

#改为下面

if [ $# -lt 1 ]; then
echo "No Args Input..."
exit
fi
case $1 in
