This article mainly introduces how to achieve HBase installation, the article is very detailed, has a certain reference value, interested friends must read it!

One: prepare

Like Hadoop, HBase supports three operating modes: stand-alone mode, pseudo-distributed mode and fully distributed mode. When installing pseudo-distribution mode, it is important to make sure that Hadoop is also running in the appropriate mode.

Installation of Hadoop: http://my.oschina.net/gently/blog/668222. (hadoop-2.6.4.tar.gz)

Installation of Zookeeper: http://my.oschina.net/gently/blog/674311 (zookeeper-3.4.8.tar.gz)

HBase download address: http://mirrors.hust.edu.cn/apache/hbase/. (hbase-1.2.1-bin.tar.gz)

Second: HBase pseudo-distributed installation

1. Place the downloaded package under Desktop and extract it to the specified directory

two。 First, modify the following properties in hbase-env.sh

Sudo gedit hbase-env.sh

3. Modify the hbase-site.xml file

Sudo gedit hbase-site.xml

Modification: pay attention to the value value in the first property, which is consistent according to the configuration information of your own hadoop.

3. Modify the regionservers file

Sudo gedit regionservers

4. Go to the bin directory of the HBase installation directory and start HBase

(after completing the above operations, you can start Hbase normally. Startup order: start Hadoop-- > then start Hbase, and close order: close Hbase-- > then close Hadoop. Make sure Hadoop starts properly)

5. View the process (Hadoop, Zookeeper, Hbase are enabled for the process here)
