Hadoop2.7.2的三種安裝模式

虛擬機使用的oracle vm，安裝的操作系統是centOs7

本地模式

1.安裝JDK

Hadoop是要安裝在JVM上運行的，所以都要安裝JDK。所以必須安裝JVM。

1.1 下載JDK

下載網址：?

http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html

選擇linux 64位系統，壓縮后綴是tar.gz?

1.2 解壓

將下載的tar包拷貝到/home/hadoop/Downloads文件夾里，進入Downloads文件夾，再直接使用命令：

tar –zxvf jdk-8u111-linux-x64.gz

解壓到當前文件夾里，然后使用命令將jdk文件夾剪切到/software/目錄下，當然得先創建/software/目錄，同時使用如下命令創建jdk軟連接：

???????? ln–s jdk1.8.0_111 jdk

1.3 配置JDK，JRE環境變量

使用vim命令修改配置文件/etc/profile

在文件尾添加：

export JAVA_HOME=/software/jdk

export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

?

再用soure /etc/profile命令，使其生效：

?

1.4 驗證

輸入：java －version?

能顯示如下信息，就表示JDK配置成功。?

[hadoop@s200 software]$ java -version

java version "1.8.0_111"

Java(TM) SE Runtime Environment (build1.8.0_111-b14)

Java HotSpot(TM) 64-Bit Server VM (build25.111-b14, mixed mode)

[hadoop@s200 software]$

2.安裝Hadoop

這里安裝本地模式

2.1下載

下載地址：?

http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/

我下載的2.7.2版本，點擊hadoop-2.72/鏈接進入下載頁面。?

下載tar包和src源碼包（源碼包供開發調試使用）。

?

2.2解壓

將hadoop-2.7.2.tar.gz包拷貝到與jdk相同的目錄/home/hadoop/Downloads下。然后使用

tar –zxvf hadoop-2.7.2.tar.gz

解壓后得到hadoop-2.7.2文件夾。然后使用命令：

???????? mv hadoop-2.7.2 /software/

將hadoop目錄剪切到/software/目錄下

?然后使用命令：

? ? ? ? ?ln–s hadoop-2.7.2 hadoop創建軟連接。

?

2.3配置Hadoop環境變量

使用vim命令修改配置文件/etc/profile

在文件尾添加：

export HADOOP_HOME=/software/hadoop

exportPATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

再用soure /etc/profile命令，使其生效。

?

2.4 驗證

使用hadoop version得到如下版本號信息，則表示安裝成功。

[hadoop@s200 software]$ hadoop version

Hadoop 2.7.2

Subversionhttps://git-wip-us.apache.org/repos/asf/hadoop.git -rb165c4fe8a74265c792ce23f546c64604acf0e41

[hadoop@s200 software]$

偽分布模式

1、安裝SSH

1.1、安裝SSH，在命令行輸入如下：

sudo??apt-get?install?openssh-server

?

1.2配置可以免密碼登陸本機

?????????在命令行輸入（注意其中的ssh前面還有一個?“?.?”?不要遺漏）

ssh-keygen??-t??rsa?-P?''?-f??~/.ssh/id_rsa?

（解釋一下上面這條命令，?ssh-keygen??代表生成密鑰；?-t??表示指定生成的密鑰?類型；?rsa??是?rsa?密鑰認證的意思；?-P??用于提供密語（接著后面是兩個單引號，?不要打錯）；?-f??表示指定生成密鑰文件）

這條命令完成后，會在當前文件夾下面的?.ssh?文件夾下創建?id_rsa?和?id_rsa.pub兩個文件，這是?SSH?的一對私鑰和公鑰，把?id_rsa.pub?（公鑰）追加到授權的?key中去，輸入如下命令：

?

cat??~/.ssh/id_rsa.pub??>>??~/.ssh/authorized_keys

?

至此，免密碼登陸本機已經配置完畢。

說明：一般來說，安裝SSH時會自動在當前用戶下創建.ssh這個隱藏文件夾，一般不會直接看到，除非安裝好了以后，在命令行使用命令ls -al才會看到。

?

1.3、?輸入?ssh??localhost?，顯示登陸成功信息。

[hadoop@s200 hadoop]$ ssh localhost

Last login: Mon Nov 21 21:53:49 2016

[hadoop@s200 ~]$

?

2、? 在本地模式的基礎上需要添加下面的操作。

3、? 修改etc/hadoop/hadoop-env.sh如下配置項

export JAVA_HOME=/software/jdk

4、配置etc/hadoop/core-site.xml

<configuration>

??? <property>

??????? <name>fs.defaultFS</name>

???????<value>hdfs://localhost:9000</value>

??? </property>

</configuration>

?

5、配置etc/hadoop/hdfs-site.xml

<configuration>

?????<property>

??????????????<name>dfs.replication</name>

??????????????<value>1</value>

?????</property>

</configuration>

?

6、配置etc/hadoop/mapred-site.xml

<configuration>

????<property>

????????<name>mapreduce.framework.name</name>

????????<value>yarn</value>

????</property>

</configuration>

?

7、配置etc/hadoop/yarn-site.xml

<configuration>

????<property>

????????<name>yarn.resourcemanager.hostname</name>

????????<value>localhost</value>

????</property>

????<property>

????????<name>yarn.nodemanager.aux-services</name>

????????<value>mapreduce_shuffle</value>

????</property>

</configuration>

?

8、使用hdfs namenode –format命令格式化文件系統

[hadoop@s200 hadoop]$ hdfs namenode -format

16/11/21 22:52:03 INFO namenode.NameNode:STARTUP_MSG:

9、啟動hdfs

[hadoop@s200 hadoop]$ start-dfs.sh

Starting namenodes on [localhost]

localhost: starting namenode, logging to/software/hadoop-2.7.2/logs/hadoop-hadoop-namenode-s200.out

localhost: starting datanode, logging to/software/hadoop-2.7.2/logs/hadoop-hadoop-datanode-s200.out

Starting secondary namenodes [0.0.0.0]

0.0.0.0: starting secondarynamenode,logging to /software/hadoop-2.7.2/logs/hadoop-hadoop-secondarynamenode-s200.out

?

10、驗證hdfs是否啟動成功，使用jps命令如出現NameNode、DataNode、SecondaryNameNode這3個進程則表示啟動成功。

[hadoop@s200 hadoop]$ jps

5283 DataNode

5587 SecondaryNameNode

5797 Jps

5112 NameNode

?

11、啟動yarn

[hadoop@s200 hadoop]$ start-yarn.sh

starting yarn daemons

starting resourcemanager, logging to/software/hadoop-2.7.2/logs/yarn-hadoop-resourcemanager-s200.out

localhost: starting nodemanager, logging to/software/hadoop-2.7.2/logs/yarn-hadoop-nodemanager-s200.out

?

12、驗證yarn是否啟動成功，使用jps命令查看有ResourceManager和NodeManager兩個進程，則表示yarn啟動成功。

[hadoop@s200 hadoop]$ jps

5283 DataNode

5587 SecondaryNameNode

5112 NameNode

6233 Jps

5883 ResourceManager

6015 NodeManager

[hadoop@s200 hadoop]$

13、通過WEB UI瀏覽 驗證

HDFS和YARN ResourceManager各自提供了web接口，通過這些接口可查看HDFS集群和YARN集群的狀態信息，訪問方式：

HDFS-NameNode? ：http://<NameNodeHost>:50070

YARN-ResourceManager ： http://<ResourceManagerHost>:8088

完全分布式模式

1）? 在偽分布模式的基礎上進行下面的步驟。

2）? 配置core-site.xml

<configuration>
? ? ????<property>
? ? ? ? ? ? ?????????<name>fs.defaultFS</name>
? ? ? ? ? ? ?????????<value>hdfs://s200</value>
? ? ????</property>
? ? ????<property>
? ? ? ? ? ? ?????????<name>hadoop.tmp.dir</name>
? ? ? ? ? ? ?????????<value>/usr/local/hadoop-${user.name}</value>
? ? ????</property>

</configuration>

3）? 配置hdfs-site.xml

<configuration>
? ? ????<property>
? ? ? ? ? ? ?????????<name>dfs.replication</name>
? ? ? ? ? ? ?????????<value>3</value>
? ? ????</property>
? ? ????<property>
? ? ? ? ? ? ?????????<name>dfs.namenode.name.dir</name>
? ? ? ? ? ? ?????????<value>file://${hadoop.tmp.dir}/dfs/name</value>
? ? ????</property>
? ? ????<property>
? ? ? ? ? ? ?????????<name>dfs.datanode.data.dir</name>
? ? ? ? ? ? ?????????<value>file://${hadoop.tmp.dir}/dfs/data</value>
? ? ????</property>
????<property>
?????????<name>dfs.namenode.secondary.http-address</name>
?????????<value>s202:50090</value>
????</property>

</configuration>

4）? 配置yarn-site.xml

<configuration>

?????<property>

????????<name>yarn.resourcemanager.hostname</name>

????????<value>s200</value>

????</property>

????<property>

????????<name>yarn.nodemanager.aux-services</name>

????????<value>mapreduce_shuffle</value>

</property>

????</configuration>

?

5）? 修改$HADOOP_HOME/etc/hadoop/slaves文件

s201

6）? 集群上面分發上面修改的4個文件

7）? 重新格式化文件系統

hdfs namenode -format

8）? 啟動hdfs文件系統

start-dfs.sh

?

注意：該步啟動文件系統的時候可能會出現如下錯誤：

FATALorg.apache.hadoop.hdfs.server.datanode.DataNode: Initialization failed forblock pool Block pool BP-336454126-127.0.0.1-1419216478581 (storage idDS-445205871-127.0.0.1-50010-1419216613930) service to /192.168.149.128:9000

產生原因，一開始配置文件中使用的是localhost ,后來改成Ip, 再次格式化了namenode引起的。

解決方案：

1，刪除dfs.namenode.name.dir和dfs.datanode.data.dir 目錄下的所有文件

2，修改hosts

[tank@localhost hadoop-2.2.0]$ cat /etc/hosts
127.0.0.1?? localhost localhost.localdomain localhost4localhost4.localdomain4
::1???????? localhostlocalhost.localdomain localhost6 localhost6.localdomain6
192.168.149.128 localhost

3,重新格式化:bin/hadoop namenode-format

4,啟動

附：如果沒有刪除datanode 格式化了namenode，則會引起datanode與namenode版本號不一致的錯誤

解決方案：

修改dfs.datanode.data.dir下的current/version中的clusterID與

dfs.namenode.name.dir的一致重啟即可。

?

9）? 啟動yarn

start-yarn.sh

10）使用jps查看各個節點的進程是否正確，如下圖則表示成功，否則為失敗。
