zookeeper集群搭建
1.在/usr/soft/zookeeper-cluster下存放zookeeper-3.4.6.tar.gz
2.解压：tar -zvxf zookeeper-3.4.6.tar.gz
3./usr/soft/zookeeper-cluster/zookeeper-3.4.6/conf
下重命名 zoo_sample.cfg为zoo.cfg
mv zoo_sample.cfg zoo.cfg
4.创建三个文件夹
[root@java zookeeper-cluster]# mkdir zookeeper-1
[root@java zookeeper-cluster]# mkdir zookeeper-2
[root@java zookeeper-cluster]# mkdir zookeeper-3
[root@java zookeeper-cluster]# ls
zookeeper-1 zookeeper-2 zookeeper-3 zookeeper-3.4.6 zookeeper-3.4.6.tar.gz
5.将解压后的Zookeeper复制到以下三个目录
[root@java zookeeper-cluster]# cp -rf zookeeper-3.4.6 zookeeper-1
[root@java zookeeper-cluster]# cp -rf zookeeper-3.4.6 zookeeper-2
[root@java zookeeper-cluster]# cp -rf zookeeper-3.4.6 zookeeper-3
6.
配置每一个 Zookeeper 的 dataDir（zoo.cfg） clientPort 分别为 2181 2182 2183

修改zoo.cfg

clientPort=2181
dataDir=/usr/soft/zookeeper-cluster/zookeeper-1/data

修改zoo.cfg

clientPort=2182
dataDir=/usr/soft/zookeeper-cluster/zookeeper-2/data

修改zoo.cfg

clientPort=2183
dataDir=/usr/soft/zookeeper-cluster/zookeeper-3/data
