하둡2 설치 프로그래밍

방화벽 열기 :  50070

# firewall-cmd --permanent --zone=public --add-port=50070/tcp

# firewall-cmd --reload


hadoop 계정 생성

# useradd hadoop


생성한 계정으로 로그인 : /home/hadoop

# su - hadoop


SSH키 생성(암호입력없이 접속하기위해)

# ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa

# cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

# chmod 0600 ~/.ssh/authorized_keys


ssh접속확인하기

# ssh localhost


ssh접속종료

# exit


현재 위치 확인 ( 위치 : /home/hadoop)

# pwd


설치 프로그램 다운로드

#wget http://apache.claz.org/hadoop/common/hadoop-2.7.6/hadoop-2.7.6.tar.gz


압축풀기

tar zxf hadoop-2.7.6.tar.gz


환경설정으로 압축푼 폴더로 이동

cd hadoop-2.7.6/etc/hadoop


PATH설정

# vim ~/.bashrc

export JAVA_HOME=/usr/lib/jvm/jre

설명

툴팁은 링크에 마우스를 올리면 메시지가 나오는 말풍선을 말합니다. 기본적으로 모든 웹브라우저에서 태그에 title 속성을 적용하면 마우스 오른쪽 아래에 말풍선이 나타나지만 부트스트랩은 보다 세련된 말풍선 효과를 나타낼 수 있습니다.

 

툴팁은 예외적으로 자바스크립트로 활성화해야 하며 data-toggle=”tooltip” 속성도 포함해야 합니다. 타겟팅을 위해 선택자를 지정해야 하는데 모든 툴팁에는 이 데이터 속성이 있어서 이를 대상으로 선택자를 정합니다. 툴팁으로 나타날 문구는 title 속성이나 data-original-title 속성에 값으로 지정합니다.

<a href=”#” data-toggle=”tooltip” title=”” data-original-title=”Default tooltip“>you probably</a>

 

자바스크립트는 다음과 같이 설정합니다.

$(“[data-toggle=’tooltip’]“).tooltip();

position:absolute와 tabel-cell을 이용한 중앙 정렬 웹

position:absolute와 tabel-cell을 이용한 중앙 정렬

  • 장점
    • ie8 이상 모든 브라우저에서 지원 가능합니다.
    • layer 안의 content 영역이 고정값이 아니라 가변이어도 자동으로 중앙정렬이 됩니다.
  • 단점
    • 코드 중첩이 여러번 되어야 합니다.

<div class="layer">
  <div class="layer_inner">
    <div class="content">Layer Contents</div>
  </div>
</div>

.layer{position:absolute;display:table;top:0;left:0;width:100%;height:100%}.layer .layer_inner{display:table-cell;text-align:center;vertical-align:middle}.layer .content{display:inline-block;background:#f00}
