一.下载HBase软件
1>.访问HBase官网并点击下载
官网地址: http://hbase.apache.org/ 博主推荐阅读: http://hbase.apache.org/book.html#arch.overview http://hbase.apache.org/book.html#faq
2>.选择您要下载的HBase版本(该版本要和开发人员协商，最好和开发人员使用的版本一致哟)
下载地址: http://hbase.apache.org/downloads.html
3>.下载HBase
二.部署HBase集群
1>.搭建HDFS HA集群

单独启动/停止/重启"HBase Master"角色: hbase-daemon.sh start master hbase-daemon.sh stop master hbase-daemon.sh restart master
单独启动/停止/重启"HBase Region Server"角色: hbase-daemon.sh start regionserver hbase-daemon.sh stop regionserver hbase-daemon.sh restart regionserver 温馨提示: 身为运维人员，只要你搭建的服务是以集群的方式工作，那第一件事情就是应该让所有节点的时间保持一致。 如果服务不依赖时间同步，如果你没有配置集群时间同步那倒无所谓，比如Hadoop服务如果各节点相差10分钟还是可以运行的，但是这对开发以后排错会产生困扰，因此我强烈建议大家配置集群时间同步。 不仅如此，因为在使用集群搭建后期的HBase，Kudu等服务，若时间不同会直接导致你集群无法启动哟~ 如果集群之间的节点时间不同步，会导致regionserver无法启动，抛出ClockOutOfSyncException异常。虽然可以通过hbase.master.maxclockskew参数来修改更大的值，但并不能根本解决问题，因此推荐大家在搭建集群之前最好配置chrony集群。 博主推荐阅读: https://www.cnblogs.com/yinzhengjie/p/12292549.html
