software preparation

1、zookeeper-3.4.9.tar.gz

2、hbase-1.1.7-bin.tar.gz

Install Zookeeper

Since Hbase needs the collaborative management of zookpeeper, first install Zookeeper.

1. First download zookeeper from the Apache website;

2. Upload the zookeeper installation package to the linux server through the xshell tool, and then enter the decompression command:

tar -zxvf zookeeper-3.4.9.tar.gz

3. Enter the conf folder and create a new zoo.cfg configuration file, the configuration is as follows:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit = 10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/opt/zookeeper/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
# autopurge.purgeInterval = 1

4. Configure environment variables

Open the configuration environment variables file

vi /etc/profile

Configure the following information

export ZOOKEEPER_HOME=/opt/zookeeper
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH

5. Start Zookeeper

Before starting zookeeper, you can start up the hdfs environment of hadoop first, that is

sbin/start-dfs.sh

Then start zookeeper

zkServer.sh start

Install Hbase

1. Download hbase from the Apache website;

2. Upload the file to the linux server and unzip the file

tar -zxvf hbase-1.1.7-bin.tar.gz

3. Configure environment variables

export HBASE_HOME=/opt/hbase
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:$PATH

4. Edit hbase-env.sh

In the conf folder, find hbase-env.sh and modify it as follows:

# The java implementation to use.  Java 1.7+ required.
export JAVA_HOME=/opt/jdk1.7.0_67

# Extra Java CLASSPATH elements.  Optional.
export HBASE_CLASSPATH=/opt/hadoop/etc/hadoop

# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=true

5. Edit hbase-site.xml

In the conf folder, find the hbase-site.xml file and configure it as:

<configuration>
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://yunpan:9000/hbase</value>
        </property>

        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>yunpan</value>
        </property>

        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
</configuration>

6. Start Hbase

start-hbase.sh
