This article introduces the relevant knowledge of "habase stand-alone installation method and basic function demonstration". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The Linux distribution used in this article is: CentOS Linux release 7.4.1708 (Core)

Prepare to create user useradd-m hadooppasswd hadoop download installation package

1.jdk goes to the official download page http://www.oracle.com/technetwork/java/javase/downloads/index.html and downloads jdk. The version I downloaded is jdk-8u151-linux-x64.tar.gz.

The 2.hbase installation package goes to the hadoop official website to download the hadoop binary package. The version I use is: hbase-1.2.6-bin.tar.gz.

Upload the packages of jdk and hbase to linux at the path: / home/hadoop.

Hbase installation and configuration installation

Log in as a hadoop user and extract the packages for jdk and hadoop, respectively.

Tar-zxvf jdk-8u151-linux-x64.tar.gztar-zxvf hbase-1.2.6-bin.tar.gz

Rename the directory of hadoop

Mv hbase-1.2.6/ hbase/hadoop runtime environment configuration

The paths to all the following files and folders are relative to the user directory / home/hadoop of the hadoop user

Set jdk path vi hbase/conf/hbase-env.sh

Set the path of jdk

Enter http://IP:16010 in the browser to view the status of hdfs. If port 50070 is not open, open port 16010 with the following command entered by the root user.

Iptables-I INPUT-p tcp-- dport 16010-j ACCEPT connection hbasehbase/bin/hbase shell

The following interface appears, which indicates that the connection is successful. You can enter the command of hbase.

Hbase (main): 001hbase 0 > basic operation instructions

Use hbase to store the following basic student information data, and do related operations.
