zookeeper集群搭建步骤

前提：准备3台linux虚机 下面是实操命令步骤

一、下载zk

[app@zknode01 ~]$ mkdir zookeeper [app@zknode01 ~]$ cd zookeeper [app@zknode01 zookeeper]$ mkdir zkdata [app@zknode01 zookeeper]$ mkdir zkdatalog [app@zknode01 zookeeper]$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz

二、解压zk

[app@zknode01 zookeeper]$ tar -xzvf zookeeper-3.4.13.tar.gz [app@zknode01 zookeeper]$ cd zookeeper-3.4.13/ [app@zknode01 zookeeper-3.4.13]$ cd conf [app@zknode01 conf]$ cp zoo_sample.cfg zoo.cfg

三、配置zoo.cfg

[app@zknode01 conf]$ vim zoo.cfg dataDir=/home/app/zookeeper/zkdata dataLogDir=/home/app/zookeeper/zkdatalog server.1=10.10.30.238:12888:13888 server.2=10.10.30.239:12888:13888 server.3=10.10.30.240:12888:13888 以上ip需配置实际地址 node2和node3重复以上步骤

四、配置myid

[app@zknode01 ~]$ echo “1” > /home/app/zookeeper/zkdata/myid [app@zknode02 ~]$ echo “2” > /home/app/zookeeper/zkdata/myid [app@zknode03 ~]$ echo “3” > /home/app/zookeeper/zkdata/myid

五、编辑zookeeper.out输出路径

在zkEnv.sh 修改ZOO_LOG_DIR="$ZOOKEEPER_PREFIX/logs"

六、启动zk

启动node01 [app@zknode01 ~]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Starting zookeeper … STARTED [app@zknode01 ~]$

启动node02 [app@zknode02 conf]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Starting zookeeper … STARTED

启动node03 [app@zknode03 conf]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Starting zookeeper … STARTED

查看node1状态 [app@zknode01 ~]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Mode: follower [app@zknode01 ~]$

查看node2状态 [app@zknode02 conf]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Mode: leader [app@zknode02 conf]$

查看node3状态 [app@zknode03 conf]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg Mode: follower [app@zknode03 conf]$

zk集群搭建完毕。
