Centos (64-bit) installation HBase detailed steps

HBase is a distributed, column-oriented, open-source database that comes from the Google paper "Bigtable: A distributed storage system of structured data" written by Fay Chang. Just as BigTable leverages the distributed data store provided by the Google File system, HBase provides bigtable-like capabilities on top of Hadoop. HBase is a sub-project of the Apache Hadoop project. HBase differs from the general relational database, which is a database suitable for unstructured data storage. The other difference is that HBase is column-based instead of row-based patterns.

Linux Environment: CentOS6.5

HBase version: hbase-0.94.16

HBase Official website: http://hbase.apache.org

1 Operating Environment Description 1.1 hard Software environment

L host operating system: Windows 4 bit, dual core, 2.2g,6g memory

L Virtual Software: Vmware®workstation 9.0.0 build-812388

L Virtual Machine Operating system: CentOS 64-bit, single core, 1G memory

L JDK:1.7.0_55 Bit

L hadoop:1.1.2

1.2 Machine network Environment

The cluster consists of three nodes: 1 Namenode, 2 datanode, where nodes can ping each other. The node IP address and host name are distributed as follows:

Serial number	IP Address	Machine name	Type	User name	Running processes
1	10.88.147.221	Hadoop1	Name node	Hadoop	NN, SNN, Jobtracer
2	10.88.147.222	Hadoop2	Data node	Hadoop	DN, Tasktracer
3	10.88.147.223	Hadoop3	Data node	Hadoop	DN, Tasktracer

All nodes are CentOS6.5 64bit systems, firewalls are disabled, a Hadoop user is created on all nodes, and the user home directory is/usr/hadoop. A directory/usr/local/hadoop is created on all nodes, and the owner is a Hadoop user.

2.2 Installation process 2.2.1 Download HBase installation package

Download the HBase stable release package from the Apache website (hbase.apache.org):

Http://mirrors.cnnic.cn/apache/hbase/hbase-0.96.2/

2.2.2 Upload HBase

Move the downloaded hbase-0.96.2-hadoop1-bin.tar.gz installation package to the/home/hadoop/downloads directory

2.2.3 Unzip and move the directory

1. Use the following command to extract the Hbase-0.96.2-hadoop1 folder that appears after decompression:

Cd/home/hadoop/downloads

TAR-ZXF hbase-0.96.2-hadoop1-bin.tar.gz

2. Start HBase

#/usr/hbase-0.94.16/bin/start-hbase.sh

If an error

+======================================================================+
| Error:java_home is not set and JAVA could isn't be found |
+----------------------------------------------------------------------+
| Download the latest Sun JDK from the Sun Java Web site |
| > http://java.sun.com/javase/downloads/< |
| |
|                                   Hadoop requires Java 1.6 or later. |
| Note:this script would find Sun Java whether you install using the |
|                             Binary or the RPM based installer. |
+======================================================================+

3, install the JDK, open the following link to download the latest JDK version

Http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

[Email protected] tools]# Mkdir/usr/local/java # #建立目录

[Email protected] tools]# MV jdk-7u79-linux-64.bin/usr/local/java/

Move packages to/usr/java

[Email protected] tools]# cd/usr/java/

[Email protected] java]# chmod 777jdk-7u79-linux-64.bin # #给安装包执行权限

[[email protected] java]#./jdk-7u79-linux-64.bin# installation succeeded when #安装出现Done

3) Configure Environment variables

After installation, you need to configure the JDK environment variables.

Modify the/etc/profile file and add the following information at the end:

Java_home=/usr/java/jdk1.7.0_29

Path= $PATH: $JAVA _home/bin

Classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

Export Java_home PATH CLASSPATH

When you have finished adding, save the exit.

In order for the/etc/profile file to take effect immediately after modification, you can use the following command:

Command: #. /etc/profile

Note:. There are spaces between the/etc/profile and the

4. Test the JDK

After installing and configuring the environment variables, the next step is to test that the JDK is installed properly.

Enter Java-version or Javac-version, if the version information is displayed, the installation is successful:

As you can see, the JDK has been installed successfully. Next, let's test a simple Hello World program.

A. Create a new Hello.java file

B. Add the following code:

Save exit.

C. Compile, run:

As can be seen from the above, the JDK compiles and runs normally.

At this point, the installation of the JDK has ended successfully.
