hadoop+hive-0.10.0完全分布式安裝方法

1、jdk版本：jdk-7u60-linux-x64.tar.gz

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

2、hive版本：hive-0.10.0.tar.gz

https://archive.apache.org/dist/hive/hive-0.10.0/

3、hadoop版本：hadoop-2.2.0.tar.gz

http://apache.fayea.com/apache-mirror/hadoop/common/hadoop-2.2.0/

4、Linux操作系統：ubuntu-14.04-server-amd64.iso

http://releases.ubuntu.com/14.04/

模擬3臺安裝,在hosts文件中添加以下信息，功能分配如下：

192.168.1.150???hdp1???//namenode,SecondaryNamenode,ResourceManager

192.168.1.151???hdp2???//datanode,nodemanager

192.168.1.152???hdp3???//datanode,nodemanager

1、jdk安裝

（1）將下載的jdk文件jdk-7u60-linux-x64.tar.gz解壓到相應的文件夾下（可根據情況自己選擇安裝路徑）:

#?tar?zxf?jdk-7u60-linux-x64.tar.gz

#?mv??jdk1.7.0_60??/usr/local/jdk7

?

（2）配置jdk?環境變量

?????#?vi?~/.bashrc???打開.bashrc文件，添加下面配置信息

export?JAVA_HOME="/usr/local/jdk7"

export?PATH="$PATH:$JAVA_HOME/bin"

?

（3）驗證是否安裝正確

#?java?-version?

java?version?"1.7.0_60"

Java(TM)?SE?Runtime?Environment?(build?1.7.0_60-b19)

Java?HotSpot(TM)?64-Bit?Server?VM?(build?24.60-b09,?mixed?mode)

?

2、新建一個用戶，如hadoop，并設置密碼

#?groupadd?hadoop?

#?useradd?-c?"Hadoop?User"?-d?/home/hadoop?-g?hadoop?-m?-s?/bin/bash?hadoop

#?passwd?hadoop

??hadoop

3、配置ssh?

(1)切換到hdp1新建的hadoop用戶下?：#?su?-?hadoop

(2)$?ssh-keygen?-t?rsa

(3)$?cat?.ssh/id_rsa.pub?>>?.ssh/authorized_keys

(4)$?ssh?localhost?驗證是否成功

(5)hdp2,hdp3采用同樣的方法配置ssh，然后將各自的.ssh/id_rsa.pub追加到hdp1的.ssh/authorized_keys中，實現hdp1到hdp2、hdp3的免密碼登錄，方便啟動服務

登錄到hdp2的hadoop用戶:scp?.ssh/id_rsa.pub?hadoop@hdp1:.ssh/hdp2_rsa

登錄到hdp3的hadoop用戶:scp?.ssh/id_rsa.pub?hadoop@hdp1:.ssh/hdp3_rsa

在hdp1中：cat?.ssh/hdp2_rsa?>>?.ssh/authorized_keys

???????????????cat?.ssh/hdp3_rsa?>>?.ssh/authorized_keys

注：以上的準備工作三臺機器應完全一樣，尤其注意安裝的目錄，修改相應的主機名等信息

?

接下來安裝Hadoop部分

1、?解壓文件,并配置環境變量

將下載的hadoop-2.2.0.tar.gz解壓到/home/hadoop路徑下:

???tar?-zxvf?hadoop-2.2.0.tar.gz?/home/hadoop/

移動hadoop-2.2.0到/usr/local目錄下：

??sudo?mv?hadoop-2.2.0?/usr/local/

注意：每臺機器的安裝路徑要相同！！

??#?vi?~/.bashrc???打開.bashrc文件，添加下面配置信息

export?HADOOP_HOME=/usr/local/hadoop

export?HADOOP_MAPRED_HOME=${HADOOP_HOME}

export?HADOOP_COMMON_HOME=${HADOOP_HOME}

export?HADOOP_HDFS_HOME=${HADOOP_HOME}

export?YARN_HOME=${HADOOP_HOME}

export?HADOOP_CONF_DIR=${HADOOP_HOME}/etc/hadoop

export?PATH=$PATH:${JAVA_HOME}/bin:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin

?

2、?hadoop配置過程

配置之前，需要在hdp1本地文件系統創建以下文件夾：

~/hadoop/dfs/name

~/hadoop/dfs/data

~/hadoop/temp

這里要涉及到的配置文件有7個：

~/hadoop/etc/hadoop/hadoop-env.sh

~/hadoop/etc/hadoop/yarn-env.sh

~/hadoop/etc/hadoop/slaves

~/hadoop/etc/hadoop/core-site.xml

~/hadoop/etc/hadoop/hdfs-site.xml

~/hadoop/etc/hadoop/mapred-site.xml

~/hadoop/etc/hadoop/yarn-site.xml

以上個別文件默認不存在的，可以復制相應的template文件獲得。

配置文件1：hadoop-env.sh

修改JAVA_HOME值（export?JAVA_HOME=/usr/java/jdk7）

配置文件2：yarn-env.sh

修改JAVA_HOME值（export?JAVA_HOME=/usr/java/jdk7）

配置文件3：slaves?（這個文件里面保存所有slave節點）

寫入以下內容：

hdp2?

hdp3

配置文件4：core-site.xml

<configuration>

<property>

<name>fs.defaultFS</name>

<value>hdfs://hdp1:9000</value>

3、復制到其他節點

這里可以寫一個shell腳本進行操作（有大量節點時比較方便）

cp2slave.sh

#!/bin/bash

scp?–r?/usr/local/hadoop?hadoop@hdp2:/usr/local/

scp?–r?/usr/local/hadoop?hadoop@hdp3:/usr/local/

4、啟動驗證

4.1?啟動hadoop

進入安裝目錄：?cd?hadoop/

(1)格式化namenode：bin/hdfs?namenode?–format

(2)啟動hdfs:?sbin/start-dfs.sh

此時在hdp1上面運行的進程有：namenode,?secondarynamenode

hdp2和hdp3上面運行的進程有：datanode

(3)啟動yarn:?sbin/start-yarn.sh

此時在hdp1上面運行的進程有：namenode,secondarynamenode,resourcemanager

hdp2和hdp3上面運行的進程有：datanode,nodemanager

(4)啟動historyserver:?sbin/mr-jobhistory-daemon.sh?start?historyserver

查看集群狀態：bin/hdfs?dfsadmin?–report

查看文件塊組成：bin/hdfs?fsck?/?-files?-blocks

查看HDFS:?http://192.168.1.150:50070

查看RM:?http://192.168.1.150:8088

4.2?運行示例程序：

先在hdfs上創建一個文件夾

bin/hadoop?jar?./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar?pi?2?1000

接下來安裝Mysql部分,存儲hive元數據

1、sudo?apt-get?install?mysql-server??按提示安裝，并設置root用戶密碼

2、創建mysql用戶hive

???$?mysql?-u?root?-p?進入root用戶

????mysql>?CREATE?USER?'hive'@'%'?IDENTIFIED?BY?'hive';?

3、授權：??

???mysql>?GRANT?ALL?PRIVILEGES?ON?*.*?TO'hive'@'%'?WITH?GRANT?OPTION;

4、登錄到hadoop?用戶?$?mysql?-u?hiv?-p?

5、創建數據庫hive

mysql>create?database?hive;?

接下來安裝Hive部分

1、?解壓文件,并配置環境變量

將下載的hive-0.10.0.tar.gz解壓到/home/hadoop路徑下。

sudo?mv?hive/usr/local/

注意：每臺機器的安裝路徑要相同！！

??#?vi?~/.bashrc???打開.bashrc文件，添加下面配置信息

export?HIVE_HOME=/usr/local/hive

export?PATH=$PATH:${HIVE_HOME}/bin

2、在hive/conf中添加hive-site.xml

<?xml?version="1.0"?>
<?xml-stylesheet?type="text/xsl"?href="configuration.xsl"?>

<configuration>

<property>
<name>hive.metastore.local</name>
<value>false</value>
<description>Thrift?uri?for?the?remote?metastore.?Used?by?metastore?client?to?connect?to?remote?metastore.</description>
</property>

<property>
<name>hive.metastore.uris</name>
<value>thrift://master:9083</value>
<description></description>
</property>

<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://master:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC?connect?string?for?a?JDBC?metastore</description>
</property>

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>Driver?class?name?for?a?JDBC?metastore</description>
</property>

<property>
<name>javax.jdo.PersistenceManagerFactoryClass</name>
<value>org.datanucleus.jdo.JDOPersistenceManagerFactory</value>
<description>class?implementing?the?jdo?persistence</description>
</property>

<property>
<name>javax.jdo.option.DetachAllOnCommit</name>
<value>true</value>
<description>detaches?all?objects?from?session?so?that?they?can?be?used?after?transaction?is?committed</description>
</property>

<property>
<name>javax.jdo.option.NonTransactionalRead</name>
<value>true</value>
<description>reads?outside?of?transactions</description>
</property>

<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
<description>username?to?use?against?metastore?database</description>
</property>

<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
<description>password?to?use?against?metastore?database</description>
</property>
</configuration>

3、將mysql?jdbc?driver拷貝到hive的lib下

4、啟動hive并測試：

hive>?show?tables;

OK
