hbase環境搭建（zookeeper）

一。配置前準備

1. java環境，Linux下。
2. hadoop環境

 

二。 hbase安裝

1.解壓 hbase-1.2.6-bin.tar.gz，重命名，賦予權限給hadoop用戶

sudo tar -zxvf  hbase-1.2.6-bin.tar.gz
sudo mv hbase-1.2.6 hbase
sudo chown -R hadoop ./hbase

 

2. 添加環境變量

sudo vim ~/.bashrc

export HBASE_HOME=/usr/local/hbase
export HBASE_CONF_DIR=$HBASE_HOME/conf
export HBASE_CLASS_PATH=$HBASE_CONF_DIR
export PATH=$PATH:$HBASE_HOME/bin

使環境變量生效

source ~/.bashrc

 

4.修改hbase-site.xml文件

 

sudo  vim /user/lcoal/hbase/conf/hbase-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
     <name>hbase.rootdir</name>
     <value>hdfs://hadoop:9000/hbase</value>
</property>
<property>
     <name>hbase.cluster.distributed</name>
     <value>true</value>
</property>
　<property>
                <name>hbase.zookeeper.quorum</name>
                <value>hadoop</value>
        </property>
        <property>
                <name>hbase.zookeeper.property.dataDir</name>
                <value>/usr/lib/jvm/habse/hadoop/data/zookeeper/zkdata</value>
        </property>

        <property>
                <name>hbase.zookeeper.property.clientPort</name>
                <value>2181</value>
        </property>
        <property>
                <name>hbase.master</name>
                <value>hdfs://hadoop:60000</value>
        </property>
        <property>
               <name>hbase.coprocessor.abortonerror</name>
                <value>false</value>
        </property>


</configuration>

 

5.修改hbase-env.sh

 sudo  vim /user/lcoal/hbase/conf/hbase-env.sh

export JAVA_HOME=/usr/local/java-8-openjdk-amd64
export HBASE_MANAGES_ZK=true
export HBASE_CLASSPATH=/usr/local/hadoop/conf

 

6.  啓動hadoop   ./hadoop/sbin/start-all.sh

7.  啓動hbase     ./hbase/bin/start-hbase.sh   出現9個進程

hadoop@hadoop:/usr/local/hadoop/sbin$ start-hbase.sh 
hadoop: starting zookeeper, logging to /usr/local/hbase/logs/hbase-hadoop-zookeeper-hadoop.out
starting master, logging to /usr/local/hbase/logs/hbase-hadoop-master-hadoop.out

14346 DataNode
15578 HQuorumPeer
15819 HRegionServer
14190 NameNode
hadoop@hadoop:/usr/local/hadoop/sbin$

 

8. hbase建表   ./hbase/bin/hbase shell

hadoop@hadoop:/usr/local/hadoop/sbin$ hbase shell

SLF4J: Found binding in [jar:file:/usr/local/hbase/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

1 row(s) in 0.0450 seconds

hbase(main):005:0>

 

三。使用zookeeper

咱們下載zookeeper並解壓，重命名

sudo tar -zxvf zookeeper-3.4.10.tar.gz
mv zookeeper-3.4.10 /usr/local/zookeeper

添加zookeeper環境變量

sudo vim ~/.bashrc

export ZOOKEEPER_HOME=/usr/local/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin

使環境變量生效

source ~/.bashrc

修改zoo.cfg文件

cd zookeeper/conf
cp zoo_sample.cfg zoo.cfg
sudo vim zoo.cfg

zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/home/hadoop/zookeeper/data
dataLogDir=/home/hadoop/zookeeper/logs
clientPort=2181

啓動zookeeper   ./zkServer.sh start

關閉zookeeper   ./zkServer.sh stop

hadoop@hadoop:$ cd zookeeper/bin
hadoop@hadoop:/usr/local/zookeeper/bin$ ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
hadoop@hadoop:/usr/local/zookeeper/bin$ jps
7889 QuorumPeerMain
7911 Jps
hadoop@hadoop:/usr/local/zookeeper/bin$ ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
hadoop@hadoop:/usr/local/zookeeper/bin$

 

在hbase中使用zookeeper

只須要修改hbase-env.sh，將管理hbase的設置默認不適用自帶zookeeper（false）

使用zookeeper+hbase時須要先啓動zookeeper，在啓動hbase。

 sudo  vim /user/lcoal/hbase/conf/hbase-env.sh

export JAVA_HOME=/usr/local/java-8-openjdk-amd64
export HBASE_MANAGES_ZK=false
export HBASE_CLASSPATH=/usr/local/hadoop/conf
