[root conf]# cp zoo_sample.cfg zoo.cfg
[root conf]# ls
configuration.xsl  logback.xml  zoo.cfg  zoo_sample.cfg

• 编辑zoo.cfg

# 修改数据目录
dataDir=/opt/apache-zookeeper-3.8.0-bin/data
dataLogDir=/opt/apache-zookeeper-3.8.0-bin/log

# 添加集群ip信息
server.1=172.16.24.174:2888:3888
server.2=172.16.24.175:2888:3888

如：172.16.24.174 服务器myid内容为1

touch /opt/apache-zookeeper-3.8.0-bin/data/myid

export ZOOKEEPER_INSTALL=/opt/apache-zookeeper-3.8.0-bin
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin

export ZOOKEEPER_INSTALL=/opt/apache-zookeeper-3.8.0-bin
export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
