This article will explain in detail how to install the HBase cluster. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

HBase is based on Hadoop, and it is assumed that you have installed the Hadoop platform.

1. Download resources

Official website: http://mirrors.cnnic.cn/apache/hbase/stable/

two。 Upload, decompress, soft connection

Note: for the process, please refer to "VMware Virtual Machine Building Hadoop2.7.1 distributed Cluster (3)"

3. Modify configuration

(1) Environmental variables

Vim / etc/profile

Export HBASE_HOME=/opt/hbase

Export PATH=$HBASE_HOME/bin:$PATH

(2) hbase-env.sh

Export HBASE_LOG_DIR=/logs/hbase

ExportHBASE_MANAGES_ZK=ture

(3) hbase-site.xml

Hbase.cluster.distributed

True

Hbase.regionserver.hlog.replication

Hfile.block.cache.size

0.5

Hbase.snapshot.enabled

True

(4) regionservers

Hadoop01

Hadoop02

Hadoop03

4. Copy

Copy the above to another node.

5. Start the cluster

(1) start HDFS

Sh start-dfs.sh

(2) start HBase

Sh bin/start-hbase.sh

Tip: it is necessary to keep the time synchronization of the cluster, otherwise RegionServer may not be able to start and report an error.

Time synchronization reference: http://www.hello-code.com/group/Hadoop/201407/1291.html

You can write a crontab script to synchronize the time.

6. View startup results

(1) JPS view process

(2) simple operation of hbase shell

(3) UI
