우측 3번째에 'Start your trial today'를 클릭해주세요.

Please click 'Start your trial today' button.

오라클 홈페이지 가입 홈페이지 Oracle cloud Page

'Start for Free'를 눌러 계정 생성을 시작합니다.

자 이제 오라클 클라우드 콘솔 메인페이지에 진입했습니다.!

we are in Oracle Cloud Conosle Main Page.

Create a VM instance

Create a VM instance 버튼을 클릭해줍니다.

please click 'Create a VM instance'

이름은 편하신대로 변경하시고 이제 이미지를 고를 차례인데요. 설정한 이름은 실제 인스턴스 내부에 영향을 끼치지 않습니다.

you can name your instance (this name won't affect any to your instnace)

저는 우분투 20.04 미니멀을 선택했습니다.

i choose Ubuntu 20.04 minimal.

ssh 접속을 위한 키 설정화면입니다.

you can setting ssh.

저는 제 퍼블릭 키를 붙여넣었습니다.

i uploaded my public ssh key file.

 

저는 2개의 인스턴스를 만들었는데요

i created two instances on purpose.

아래 2개는 삭제한 인스턴스를 의미합니다.

the state 'Terminated' means 'DELETED'

본인이 만든 인스턴스의 상태가 Provisioning이라면 조금 더 기다리시면 됩니다. 1~3분 소요됩니다.

instance state from Provisioning to Running would be taken 1~3 minutes.

인스턴스 디테일

만든 인스턴스의 디테일을 보고자하시면 인스턴스의 이름을 클릭하시면 됩니다.

click instnace name if you want to see detail.

자 정상적으로 생성이 되었으니, ssh 접속 여부를 확인해보아야겠죠?

now your instance is running thus you may want to check ssh-possible or not.

인스턴시 생성시에 넣었던 id_rsa.pub을 가진 터미널에서 ssh 접속을 시도합니다.(저는 iterm2를 좋아합니다..)

Open the terminal that has id_rsa.pub file that you uploaded when you create instance. (personally i like iterm2)

유저네임은 인스턴스 초기 유저 네임인 ubuntu를 넣어주셔야합니다.

user name is ubuntu as default.

ssh ubuntu@YOUR_IP_ADDRESS

문제 없이 샥- 들어가진다면 인스턴스 생성 성공!

if you can enter that it's success!

지난 시간동안 우리는 하둡을 설치와 예제 실현을 통해 정상적으로 인스톨됨을 확인한 바가 있다.

2018/02/10 - [프로그래밍발전소 ♫/Hadoop발전소♫] - OSX에 Hadoop 설치하기 (ver 1)

2018/02/11 - [분류 전체보기] - OSX에 Hadoop 설치하기 (ver 2)

이번에는 하둡용 어플을 만들어보기전에 우리가 지지고볶고 해야될 데이터가 필요하기 때문에

데이터를 다운받아보도록합시다. 

stat-computing.org에서 Download the Data를 클릭하시고~

그럼 1987~2008까지의 데이터들을 다운받아야겠죠? 허나 수기로 일일이 다운받는다면..

무슨 프로그래밍하는 사람의로써의 의미가 있겠습니까..

저번에 써먹었던 wget 명령어를 활용해 쉘을 만들어봅시다.


  1 #!/bin/sh

  2 

  3 for((i=1987; i<=2009;i++))

  4 do

  5 wget http://stat-computing.org/dataexpo/2009/${i}.csv.bz2

  6 done

~                                                                               

~                                                                               

~                                                                               

~                                                                               

위에같이 for문으로 1987~2009까지 지정해주고 wget메소드를 활용하고 중간에 파라미터를 집어넣어서 저 쉘을 실행시키면 

설정해준 기간까지의 데이터를 다운받게끔 진행합시다.  실행하기전에 chmod 777로 실행권한을 줘야합니다.

허나, 데이터 처리과정 중에 에러를 야기할 수 있는 사항이기 때문에 지우도록합시다.

1987~2008의 파일들을 만져야하니 커맨드 한줄로도 가능하긴합니다.
