Hadoop環境搭建之Zookeeper、Hbase安裝

1、說明

一、環境說明

十一、3臺服務器（h一、h二、h3）的SSH配置見：Hadoop環境搭建之SSH免密碼相互訪問

十二、hadoop的安裝配置見：Hadoop環境搭建之Hadoop安裝

二、軟件說明

zookeeper：zookeeper-3.3.1.tar.gz ， 下載地址：https://yunpan.cn/cS45WHyjTIR2c （提取碼：92d4）

hbase：hbase-0.94.12.tar，下載地址：https://yunpan.cn/cS455DsCMYiyV （提取碼：fbe6）

2、安裝zookeeper

因爲hbase須要zookeeper作協同服務，因此得先安裝zookeeper

2一、將zookeeper-3.3.1.tar.gz在/bdata/中解壓，解壓後的文件爲zookeeper-3.3.1,命令以下：

tar -zxvf zookeeper-3.3.1.tar.gz

2二、配置zookeeper

22一、切換到zookeeper-3.3.1的conf目錄，將zoo_sample.cfg複製爲zoo.cfg

cp zoo_sample.cfg zoo.cfg

22二、修改zoo.cfg的內容爲：

# 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.
dataDir=/bdata/zookeeper-3.3.1/server/data
# the port at which the clients will connect
clientPort=2181
server.1=h1:2888:3888
server.2=h2:2888:3888
server.3=h3:2888:3888

其中h一、h二、h3是三個服務器

22三、建立/bdata/zookeeper-3.3.1/server/data目錄，並在目錄建立myid的文件，h一、h二、h3相應目錄下的文件內容依次爲一、二、3

2三、將配置好的zookeeper-3.3.1發送給h二、h3的/bdata目錄下，分別執行如下命令

scp -r /bdata/zookeeper-3.3.1 root@h2:/bdata/

scp -r /bdata/zookeeper-3.3.1 root@h3:/bdata/

2四、修改h二、h3  /bdata/zookeeper-3.3.1/server/data/myid的內容爲二、3

3、安裝Hbase

3一、將hbase-0.94.12.tar在/bdata目錄下解壓，解壓後的文件名爲hbase-0.94.12，目錄以下

tar -zxvf hbase-0.94.12.tar

3二、配置文件

32一、修改/bdata/hbase-0.94.12/conf/hbase-env.sh，將其內容修改成

# Set environment variables here.

# The java implementation to use.  Java 1.6 required.
#export JAVA_HOME=/usr/java/jdk.1.6.0_45
export JAVA_HOME=/usr/java/jdk1.6.0_45
# Extra Java CLASSPATH elements.  Optional.
# export HBASE_CLASSPATH=

# The maximum amount of heap to use, in MB. Default is 1000.
# export HBASE_HEAPSIZE=1000

# Extra Java runtime options.
# Below are what we set by default.  May only work with SUN JVM.
# For more on why as well as other possible settings,
# see http://wiki.apache.org/hadoop/PerformanceTuning
export HBASE_OPTS="-ea -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"

# Uncomment below to enable java garbage collection logging.
# export HBASE_OPTS="$HBASE_OPTS -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:$HBASE_HOME/logs/gc-hbase.log" 

# Uncomment and adjust to enable JMX exporting
# See jmxremote.password and jmxremote.access in $JRE_HOME/lib/management to configure remote password access.
# More details at: http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html
#
# export HBASE_JMX_BASE="-Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"
# export HBASE_MASTER_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10101 -javaagent:lib/HelloWorldAgent.jar"
# export HBASE_REGIONSERVER_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10102"
# export HBASE_THRIFT_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10103"

# export HBASE_SLAVE_SLEEP=0.1

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

此文件主要配置了jdk的安裝路徑，以及「HBASE_MANAGES_ZK」是否管理一個zookeeper集羣，其值是「true」表示啓動hbase的時候，他會去啓動zookeeper

32二、配置hbase-site.xml，將其內容該爲

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
 
<property>
        <name>hbase.rootdir</name>
        <value>hdfs://h1:9000/hbase</value>
</property>
 
<property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
</property>
 
<property>
        <name>hbase.master.port</name>
        <value>60000</value>
</property>
 
<property>
        <name>hbase.zookeeper.quorum</name>
        <value>h1,h2,h3</value>
</property>
 
</configuration>

3三、將配置好的hbase-0.94.12發送到h二、h3的/bdata/目錄下，在h1下分別執行如下命令

scp -r /bdata/hbase-0.94.12 root@h2:/

scp -r /bdata/hbase-0.94.12 root@h3:/

3四、啓動hbase

在/bdata/hbase-0.94.12/bin目錄下執行./start-hbase

cd /bdata/hbase-0.94.12/bin

./start-hbase

四、簡單玩玩hbase

若是前邊幾個步驟執行順利的話，接下來咱們就進入hbase的shell控制檯，去hbase進行簡單的操做吧

4一、進入控制檯

cd /bdata/hbase-0.94.12/bin/

./hbase shell

4二、建立一張表

建立了表，名稱爲t_user，列簇爲name，other

4三、插入兩條條數據

行鍵爲liw，在列簇name下邊建了列firstname、lastname

4四、查看插入的數據
