Hbase installation and configuration tutorial under Linux

Hbase installation and configuration under Linux

First, install Hadoop

Linux Hadoop 2.7.3 Installation and Setup

1. Download the Hbase installation package

Click to enter the Hbase official website to download

http://hbase.apache.org/downloads.html

2. Installation

Upload the downloaded Hbase installation package to the specified directory on the server (unlimited, depending on the actual situation) and decompress it.

3. Configure the JAVA_HOME environment variable

Find the conf/hbase-env.sh file in the hbase installation directory, uncomment the JAVA_HOME line in the file and change it to the actual path of the local JDK.

	export JAVA_HOME=/wys/jdk1.8.0_311/
	# Because hbase comes with zk, here true is to use export HBASE_MANAGES_ZK=true

4. (Optional) Configure hbase-site.xml

Modify the conf/hbase-site.xml file

<configuration>
 <!-- hbase data storage directory -->
  <property>
    <name>hbase.rootdir</name>
    <value>file:/hadoop/hbase-2.4.7/data</value>
  </property>

  <!-- ZooKeeper data file path -->
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/hadoop/hbase-2.4.7/zkdata</value>
  </property>

<!--Specify the zk address as the machine name-->
<property>
        <name>hbase.zookeeper.quorum</name>
        <value>VM-16-8-centos</value>
</property>
<property>
  <name>hbase.zookeeper.property.clientPort</name>
  <value>2181</value>
</property>
 <!-- ZooKeeper node name for storing hbase data -->
    <property>
        <name>zookeeper.znode.parent</name>
        <value>/hbase</value>
    </property>
    <!-- Cluster mode, distributed or stand-alone mode. If set to false, the HBase process and Zookeeper process will be in the same JVM process. If set to true, an error will be reported. -->
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
<property>
  <name>hbase.unsafe.stream.capability.enforce</name>
  <value>false</value>
</property>
<property>
   <name>hbase.master.maxclockskew</name>
   <value>120000</value>
</property>
 <!--Set the enabled port to be accessible from the external network-->
<property>
<name>hbase.master.ipc.address</name>
<value>0.0.0.0</value>
</property>
<property>
<name>hbase.regionserver.ipc.address</name>
<value>0.0.0.0</value>
</property>

</configuration>

Note: The following controls whether the port can be accessed from the external network.

<property>
<name>hbase.master.ipc.address</name>
<value>0.0.0.0</value>
</property>
<property>
<name>hbase.regionserver.ipc.address</name>
<value>0.0.0.0</value>
</property>

 0 0.0.0.0: The one that starts with 127.0.0.1:40648 is accessible from the Internet. This Internet cannot access it. 

5. Start Hbase

Run the ./bin/start-hbase.sh command in the Hbase installation directory to start Hbase.

In stand-alone mode, after Hbase is successfully started, an HMaster and ZooKeeper background process will be generated. You can browse the Hbase monitoring page by accessing http://localhost:16010 in the browser.

After successful startup, execute ./bin/hbase shell in the Hbase installation directory to enter the Hbase command line interface.

Phoenix installation and configuration

1. Download the Hbase installation package

Click to enter Phoenix official website to download

2. Installation

Upload the downloaded Phoenix installation package to the specified directory on the server (unlimited, depending on the actual situation) and decompress it.

3. Configuration

Copy phoenix-[version]-server.jar in the Phoenix installation directory to the lib directory of Hbase and restart Hbase.

4. Run

Execute ./bin/sqlline.py 127.0.0.1:2181 in the Phoenix installation directory to connect to Hbase. After the connection is successful, execute the !tables command to see several system tables that are automatically created.

**Note:** The first connection may be slow because several system tables will be created, as shown above.

Connecting to Phoenix from other hosts on the Internet or intranet

Connect Phoenix to HBase via DBeaver
