Tar -zxvf zookeeper-3.4.10.tar.gz
[root@hmaster local]# rm -rf zookeeper-3.4.10.tar.gz
远程传输zookeeper-3.4.10到其他节点
[root@hmaster local]# scp -r /usr/local/zookeeper-3.4.10 root@hslave1:/usr/local/
[root@hmaster local]# ls
bin etc games hadoop hive include java lib lib64 libexec python3Dir sbin share src zookeeper-3.4.10
[root@hmaster conf]# ls
configuration.xsl log4j.properties zoo_sample.cfg
[root@hmaster conf]# cp zoo_sample.cfg zoo.cfg
[root@hmaster conf]# ls
configuration.xsl log4j.properties zoo.cfg zoo_sample.cfg
编辑配置文件
[root@hmaster conf]# vim zoo.cfg
#第一个端口号2888 是Leader与follower之间通讯的端口；3888是选举使用的端口号
#autopurge.purgeInterval=1
server.0=172.26.19.40:2888:3888
server.1=172.26.19.41:2888:3888
server.2=172.26.19.42:2888:3888
根据zoo.cfg 文件中dataDir=/tmp/zookeeper 创建相应目录，配置myid文件,使得集群映射
[root@hslave1 conf]# cd /tmp
[root@hslave1 tmp]# ls
hsperfdata_root systemd-private-d38862e2d5524a42994bdd9ddd858f50-chronyd.service-nIGJPI
[root@hslave1 tmp]# mkdir zookeeper
[root@hslave1 tmp]# vim myid
[root@hslave1 tmp]# more myid
1
[root@hslave1 tmp]#
每台机器输入对IP的信息server.0=172.26.19.40:2888:3888；应该输入0
[root@hmaster bin]# ./zkServer.sh status
[root@hmaster bin]# ./zkServer.sh start

查看zookeeper日志文件
[root@hmaster bin]# more zookeeper.out
