Hadoop-2.7下搭建Zookeeper集群

---

配置Zookeeper环境变量

export ZOOKEEPER_HOME=/op/zookeeper-3.4
export PATH=$PATH:$ZOOKEEPER_HOME/bin

创建文件夹每台机器都得建

mkdir /opt/zookeeper-3.4/data
mkdir /opt/zookeeper-3.4/dataLog
touch /opt/zookeeper-3.4/data/myid

编辑/opt/zookeeper-3.4/data/myid文件

hserver-1上写入1

hserver-2上写入2

hserver-3上写入3

修改配置文件（每台机器）

cp /opt/zookeeper-3.4/conf/zoo_smaple.cfg /opt/zookeeper-3.4/conf/zoo.cfg

在文件zoo.cfg最后添加(每台机器都需要写)

dataDir=/opt/zookeeper-3.4/data
dataLogDir=/opt/zookeeper-3.4/dataLog
server.1=hserver-1:2888:3888
server.2=hserver-2:2888:3888
server.3=hserver-3:2888:3888

启动zookeeper(每台机器都要启动)

./bin/zkServer.sh start
