1. 다운로드 받기 (http://cassandra.apache.org/download/)

cassandra@ubuntu:~$ wget http://apache.mirror.cdnetworks.com/cassandra/1.1.6/apache-cassandra-1.1.6-bin.tar.gz

2. 압축풀기

cassandra@ubuntu:~$ tar xvfz apache-cassandra-1.1.6-bin.tar.gz

cassandra@ubuntu:~$ mkdir bin

cassandra@ubuntu:~$ mv apache-cassandra-1.1.6 ./bin

cassandra@ubuntu:~$ cd bin

cassandra@ubuntu:~/bin$ ln -s apache-cassandra-1.1.6 cassandra

3. 로그 설정이라던지, 각종 설정 변경하기는 아래 두개의 파일을 수정하면 됨.

cassandra@ubuntu:~/bin$ cd cassandra

cassandra@ubuntu:~/bin/cassandra$ cd conf

cassandra.yaml --> 기본적인 설정들

log4j-server.properties --> 로그 설정들.

cassandra@ubuntu:~$ bin/cassandra/bin/cassandra
