104-Zookeeper集群搭建[leader+follower模式]

1.下载zookeeper

http://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/

2.解压缩

在node1主机上，解压zookeeper的压缩包到/export/server路径下去，然后准备进行安装

3.修改配置文件

(base)[root@node1 software]# cd /export/server/(base)[root@node1 server]# lltotal932972drwxr-xrwx28root root4096Dec309:32 anaconda3 drwxr-xrwx10root root201Aug615:23 apache-hive-3.1.2-bin -rwxr-xrwx1root root278813748Aug614:29 apache-hive-3.1.2-bin.tar.gz drwxr-xrwx2root root40Jul3009:46 finebi drwxr-xrwx11root root227Jul2115:56 hadoop-3.3.0 -rwxr-xrwx1root root456364743Jul2114:57 hadoop-3.3.0-Centos7-64-with-snappy.tar.gz lrwxrwxrwx1hadoop hadoop28Dec1514:35 jdk ->/export/server/jdk1.8.0_241/ drwxr-xrwx71014310143245Dec112019jdk1.8.0_241 -rwxr-xrwx1root root194545143Jul2114:27 jdk-8u241-linux-x64.tar.gz drwxr-xrwx2root root4096Jul2814:11 mysql drwxr-xrwx6root root56Aug1814:42 python3.10.4 drwxr-xrwx17hadoop hadoop4096Aug1814:42 Python-3.10.4 -rwxr-xrwx1root root25612387Aug1814:34 Python-3.10.4.tgz lrwxrwxrwx1hadoop hadoop40Dec310:48 spark ->/export/server/spark-3.2.0-bin-hadoop3.2 drwxr-xrwx15hadoop hadoop235Dec1514:37 spark-3.2.0-bin-hadoop3.2 drwxr-xr-x10hadoop hadoop4096Feb202014zookeeper-3.4.6(base)[root@node1 server]# ln -s zookeeper-3.4.6/ zookeeper(base)[root@node1 server]# cd /export/server/zookeeper/conf/(base)[root@node1 conf]# cp zoo_sample.cfg zoo.cfg(base)[root@node1 conf]# mkdir -p /export/server/zookeeper/zkdatas/(base)[root@node1 conf]# vim zoo.cfg

vim zoo.cfg配置文件添加如下内容:

#Zookeeper的数据存放目录dataDir=/export/server/zookeeper/zkdatas# 保留多少个快照autopurge.snapRetainCount=3# 日志多少小时清理一次autopurge.purgeInterval=1# 集群中服务器地址server.1=node1:2888:3888 server.2=node2:2888:3888 server.3=node3:2888:3888

4.添加myid配置

(base)[root@node1 conf]# vim zoo.cfg(base)[root@node1 conf]# echo 1 > /export/server/zookeeper/zkdatas/myid(base)[root@node1 conf]# cd /export/server/zookeeper/zkdatas(base)[root@node1 zkdatas]# lltotal4-rw-r--r--1root root2Dec1614:15 myid(base)[root@node1 zkdatas]#

5.安装包分发并修改myid的值

5.1 第node1上面执行以下两个命令

(base)[root@node1 zkdatas]# cd /export/server/(base)[root@node1 server]# scp -r /export/server/zookeeper-3.4.6/ node2:$PWD拷贝过程代码省略......(base)[root@node1 server]# scp -r /export/server/zookeeper-3.4.6/ node2:$PWD拷贝过程代码省略......

5.2在node2机器上建立软连接, 并修改myid的值为2

(base)[root@node2 ~]# cd /export/server/您在 /var/spool/mail/root 中有新邮件(base)[root@node2 server]# ln -s zookeeper-3.4.6/ zookeeper(base)[root@node2 server]# echo 2 > /export/server/zookeeper/zkdatas/myid(base)[root@node2 server]#

5.3在node3机器上建立软连接, 并修改myid的值为3

(base)[root@node3 ~]# cd /export/server/您在 /var/spool/mail/root 中有新邮件(base)[root@node3 server]# ln -s zookeeper-3.4.6/ zookeeper(base)[root@node3 server]# echo 3 > /export/server/zookeeper/zkdatas/myid(base)[root@node3 server]#

6.三台机器启动zookeeper服务

三台机器分别启动zookeeper服务！！！
在node1 node2 node3 上分别执行下面的命令:

/export/server/zookeeper/bin/zkServer.sh start

分别查看一下node1、node2、node3的启动状态

/export/server/zookeeper/bin/zkServer.sh status

到此为止zookeeper集群搭建完毕!
