Docker를 보다 Hadoop을 설치 해볼 수 있는 자료가 있어 따라해본다.

역시 대단한 분들이 많이 계시다는~잘 동작한다 ... 무엇이든 시작은 설치 부터~


1. Java 설치를 위해 파이선과 공통개발 패키지 설치

# apt-get install software-properties-common phython-software-propertie


2. Java 설치

# apt-get update

# apt-get install oracle-java8-installer 


3. # java -version

java version "1.8.0_60"

Java(TM) SE Runtime Environment (build 1.8.0_60-b27)

Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)


4. Hadoop 설치 위해 다운로드

# wget http://mirror.apache-kr.org/hadoop/common/hadoop-2.7.1/hadoop-2.7.1.tar.gz


참고.

현재 최신 버전은 아래 위치에서 확인 가능

http://mirror.apache-kr.org/hadoop/common/current/


5. 압축풀기 및 '/' 및으로 이동

# tar zxvf hadoop-2.7.1.tar.gz 

# mv hadoop-2.7.1 /hadoop


6. vim 설치(옵션)

# apt-get install vim


7. ~/.bashrc 파일에 환경변수 추가 후 적용

# vim ~/.bashrc


export JAVA_HOME=/usr/lib/jvm/java-8-oracle

export HADOOP_HOME=/hadoop

export HADOOP_CONFIG_HOME=$HADOOP_HOME/etc/hadoop

export PATH=$PATH:$HADOOP_HOME/bin

export PATH=$PATH:$HADOOP_HOME/sbin


# source ~/.bashrc


# hadoop version

Hadoop 2.7.1

Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r 15ecc87ccf4a0228f35af08fc56de536e6ce657a

Compiled by jenkins on 2015-06-29T06:04Z

Compiled with protoc 2.5.0

From source with checksum fc0a1a23fc1868e4d5ee7fa2b28a58a

This command was run using /hadoop/share/hadoop/common/hadoop-common-2.7.1.jar


8. Hadoop 설정 구성/수정

# cd /hadoop/etc/hadoop


# vim core-site.xml 

<configuration>

<property>

<name>hadoop.tmp.dir</name>

<value>/hadoop/tmp</value>

</property>


<property>

<name>fs.default.name</name>

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

<final>true</final>

</property>

</configuration>


# vim hadoop-env.sh

export JAVA_HOME=/usr/lib/jvm/java-8-oracle


# vim mapred-site.xml

<configuration>

<property>

<name>mapred.job.tracker</name>

<value>localhost:9001</value>

</property>

</configuration>


# vim hdfs-site.xml 

<configuration>

<property>

<name>dfs.replication</name>

<value>2</value>

<final>true</final>

</property>


<property>

<name>dfs.namenode.name.dir</name>

<value>/hadoop/namenode</value>

<final>true</final>

</property>


<property>

<name>dfs.datanode.data.dir</name>

<value>/hadoop/datanode</value>

<final>true</final>

</property>

</configuration>


# vim yarn-site.xml 

<configuration>


<!-- Site specific YARN configuration properties -->

<property>

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

<value>mapreduce_shuffle</value>

</property>


<property>

<name>yarn.nodemanager.aux-services.mapreduce_suffle.class</name>

<value>org.apache.hadoop.mapred.ShuffleHandler</value>

</property>


<property>

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

<value>master</value>

</property>

</configuration>


9. Hadoop directory에 namenode 폴더 생성

# mkdir /hadoop/namenode


10. namedoe를 format

# hadoop namenode -format


11. ssh 설치

# apt-get install ssh


12. ssh 암호화 키 생성

# ssh-keygen -t rsa -P "-f ~/ssh/id_dsa

# cd .ssh

# cat id_dsa.pub >> authorized_keys


13. ssh 자동 수행 설정 후 적용

# vim ~/.bashrc

#autorun

/usr/sbin/sshd


# mkdir /var/run/sshd

# source ~/.bashrc


14. Hadoop 시작

# start-all.sh


Are you sure you want to continue connecting (yes/no)? yes


15. 구동 상태 확인

# jps

12151 NodeManager

12247 Jps

11528 NameNode

11676 DataNode

11884 SecondaryNameNode

12029 ResourceManager


16. WordCount Test

text 파일 저장을 위한 디렉토리 생성

# hadoop fs -mkdir /input


hadoop 디렉토리의 라이선스 파일을 입력

#hadoop fs -put LICENSE.txt /input


WordCount 수행

#hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-example-2.7.1.jar wordcount /input /output


결과 확인

# hadoop fs -cat /output/*


Display

Ubuntu 14.04.2 LTS를 설치해보니, 12.x 때와 많이 달라진듯하다 ...

Ubuntu에서 UI를 잘 사용안하기도 했지만, Desktop UI가 설치되니, 영 적응이 안되는 ...

바탕화면에서 우클릭을 해보니 월래 ㅡㅡ; 터미널 바로가기가 안보인다 ... 이건 머지 ㅠ_ㅠ


Ubuntu Icon을 클릭 후 검색창에 터미널을 검색하니 보이긴한다 ...


일단 열고 ...


여기서 우클릭하니 런처 고정 버튼이 있다.



왜 이케 해놓은 거냥 ㅡ.ㅡ; 예전 팝업 열기가 좋다. 이건 불편하다. 흑흑...

Ubuntu Kdump 구성 (Test 기준: Ubuntu 14.04.1)

Test 환경

Model : VM
OS : Ubuntu 14.04.1

1. root 계정 활성화 (선택)

# sudo passwd root

 

2. ssh daemon 설치 (선택)

# sudo apt-get install ssh

 

3. Dump 생성을 위한 패키지 설치 (네트워크 연결 필요)

# sudo apt-get install linux-crashdump

 

4. 덤프 생성을 위한 구성

1) crashkernel 용량 설정

# sudo vim /etc/default/grub.d/kexec-tools.cfg

 

2) kdump 활성화

# sudo vim /etc/default/kdump-tools

USE_KDUMP=1

 

3) 아래 명령을 통해 덤프 생성 가능 상태 확인(1이 나와야 정상이며, 0인 경우 구성 점검 필요)

# cat /sys/kernel/kexec_crash_loaded

 

5. 덤프 생성

# echo c > /proc/sysrq-trigger

이슈 : "Shellshock" bash 쉘 취약점

취약사항 : 원격의 공격자가, bash의 환경 변수 할당 시 문자열 코드를 전달하는 과정에 공격자의 임의의 악성코드를 실행할 수 있는 취약 사항이 2014-09-24일 발견됨

 

확인된 취약사례

1. bash 쉘에서 수행되는 Apache HTTP Server의 CGI Scriptis (via mod-cgi and mod_cgid)

2. DHCP Clients

3. Force Command를 사용하는 OpenSSH Server

4. bash를 사용하는 네트워크 관련 서비스들

 

각 OS 제조사에서는 현재 bash 쉘 관련 패치를 긴급 배포 중이다.
