2015.12.08 하둡 클러스터 환경 및 R 분석 서버 구축

하둡 클러스터 환경 및 R 분석 서버 구축

Develop/SERVER SIDE | 2015. 12. 8. 20:07

※ 개발 서버 구성

/etc/hosts

192.168.0.101   namenode
192.168.0.102   datanode01
192.168.0.103   datanode02
192.168.0.104   datanode03

각 서버에 호스트 등록

※ 하둡 환경 구축

하둡 설치

$ get http://apache.mirror.cdnetworks.com/hadoop/common/hadoop-2.6.2/hadoop-2.6.2.tar.gz
$ tar xvfz hadoop-2.6.2.tar.gz
$ mv hadoop-2.6.2 /usr/local/hadoop
$ chown -R hadoop:hadoop /usr/local/hadoop

하둡 계정 생성 -> hadoop/hadoop (each server)
```
$ useradd hadoop
$ passwd hadoop
```

하둡 계정 SSH Key 배포

$ ssh-keygen -t rsa
$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@namenode
$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@datanode01
$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@datanode02
$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@datanode03

하둡 데이터 폴더 생성 -> (each server)

$ mkdir -p /data/hadoop/tmp
$ mkdir -p /data/hadoop/dfs/name
$ mkdir -p /data/hadoop/dfs/data

chown -R hadoop:hadoop /data/hadoop/

환경 변수 등록 -> (each server)
