Zookeeper伪分布式安装_DATA数据猿_zookeeper伪分布式

未知 02-07 8338

Zookeeper伪分布式安装 1.预备工作 1.一台服务器 2.伪分布式zookeeper 1,2,3 3.创建zookeeper目录结构 zoo_1/2/3 用于存放节点的快照 zoo_2_dataLog 用于存放节点的事务日志 4.将zookeeper的压缩包解压到此处并改名为zookeeper-3.6.3 5.配置环境变量:vim /etc/profile 添加 export ZK_HOME=/zxy/apps/zookeeper/zookeeper-3.6.3 export PATH=$PATH:$ZK_HOME/bin 刷新资源 source /etc/profile

2.分配myid #server1 echo "1" > /zxy/apps/zookeeper/zoo_1/myid #server2 echo "2" > /zxy/apps/zookeeper/zoo_1/myid #server3 echo "3" > /zxy/apps/zookeeper/zoo_1/myid 3.创建不同节点配置文件 [root@hadoop_zxy conf]# cp zoo_sample.cfg zoo1.cfg [root@hadoop_zxy conf]# cp zoo_sample.cfg zoo2.cfg [root@hadoop_zxy conf]# cp zoo_sample.cfg zoo3.cfg [root@hadoop_zxy conf]# ls configuration.xsl log4j.properties zoo1.cfg zoo2.cfg zoo3.cfg zoo_sample.cfg 4.修改配置文件内容

（三个节点的配置文件只有dataDir、dataLogDir、clientPort不同）

vim zoo1.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/zxy/apps/zookeeper/zoo_1 dataLogDir=/zxy/apps/zookeeper/zoo_1_dataLog clientPort=2181 server.1=hadoop_zxy:2887:3887 server.2=hadoop_zxy:2888:3888 server.3=hadoop_zxy:2889:3889

vim zoo2.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/zxy/apps/zookeeper/zoo_2 dataLogDir=/zxy/apps/zookeeper/zoo_2_dataLog clientPort=2182 server.1=hadoop_zxy:2887:3887 server.2=hadoop_zxy:2888:3888 server.3=hadoop_zxy:2889:3889

vim zoo3.cfg

tickTime=2000 initLimit=10 syncLimit=5 dataDir=/zxy/apps/zookeeper/zoo_3 dataLogDir=/zxy/apps/zookeeper/zoo_3_dataLog clientPort=2183 server.1=hadoop_zxy:2887:3887 server.2=hadoop_zxy:2888:3888 server.3=hadoop_zxy:2889:3889 5.启动zookeeper [root@hadoop_zxy zookeeper-3.6.3]# bin/zkServer.sh start zoo1.cfg bin/zkServer.sh start zoo2.cfg bin/zkServer.sh start zoo3.cfg 6.查看进程(zookeeper已正常) [root@hadoop_zxy zookeeper-3.6.3]# jps 29858 QuorumPeerMain 29715 QuorumPeerMain 19364 Jps 29977 QuorumPeerMain [root@hadoop_zxy zookeeper-3.6.3]# 7.查看节点的leader和follower(半数原则) [root@hadoop_zxy zookeeper-3.6.3]# bin/zkServer.sh status conf/zoo1.cfg ZooKeeper JMX enabled by default Using config: conf/zoo1.cfg Client port found: 2181. Client address: localhost. Client SSL: false. Mode: follower [root@hadoop_zxy zookeeper-3.6.3]# bin/zkServer.sh status conf/zoo2.cfg ZooKeeper JMX enabled by default Using config: conf/zoo2.cfg Client port found: 2182. Client address: localhost. Client SSL: false. Mode: leader [root@hadoop_zxy zookeeper-3.6.3]# bin/zkServer.sh status conf/zoo3.cfg ZooKeeper JMX enabled by default Using config: conf/zoo3.cfg Client port found: 2183. Client address: localhost. Client SSL: false. Mode: follower 8.使用脚本管理(拓展)

vim start-zookeeper.sh

#!/bin/bash # filename:start-zookeeper.sh # autho:zxy # date:2022-01-12 # KAFKA的安装路径 ZOOKEEPER_HOME=/zxy/apps/zookeeper/zookeeper-3.6.3 # 接受参数 CMD=$1 ## 帮助函数 usage() { echo "usage:" echo "start-zookeeper.sh z1/z2/z3" echo "description:" echo " z1:start zoo_1.cfg" echo " z2:start zoo_2.cfg" echo " z3:stop zoo_3.cfg" exit 0 } if [ ${CMD} == "z1" ];then # 启动zookeeper1服务 sh $ZOOKEEPER_HOME/bin/zkServer.sh start $ZOOKEEPER_HOME/conf/zoo1.cfg elif [ ${CMD} == "z2" ];then # 启动zookeeper2服务 sh $ZOOKEEPER_HOME/bin/zkServer.sh start $ZOOKEEPER_HOME/conf/zoo2.cfg elif [ ${CMD} == "z3" ];then # 启动zookeeper3服务 sh $ZOOKEEPER_HOME/bin/zkServer.sh start $ZOOKEEPER_HOME/conf/zoo3.cfg else usage fi

整个zookeeper打包文件，包含脚本
