 OS: Centos 6

 uname : Linux HyBoostF80 2.6.32-696.3.1.el6.x86_64 #1 SMP Tue May 30 19:52:55 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

1. 기본 RPM 설치 (http://cassandra.apache.org/download/)

Installation from RPM packages

• For the <release series> specify the major version number, without dot, and with an appended x.
• The latest <release series> is 311x.
• For older releases, the <release series> can be one of 30x, 22x, or 21x.

• (Not all versions of Apache Cassandra are available, since building RPMs is a recent addition to the project.)

• Add the Apache repository of Cassandra to /etc/yum.repos.d/cassandra.repo, for example for the latest 3.11 version:

[cassandra]
name=Apache Cassandra
baseurl=https://www.apache.org/dist/cassandra/redhat/311x/
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://www.apache.org/dist/cassandra/KEYS

• Install Cassandra, accepting the gpg key import prompts:

sudo yum install cassandra

Start Cassandra (will not start automatically):

service cassandra start

Systemd based distributions may require to run systemctl daemon-reload once to make Cassandra available as a systemd service. This should happen automatically by running the command above.

Make Cassandra start automatically after reboot:

chkconfig cassandra on

Please note that official RPMs for Apache Cassandra only have been available recently and are not tested thoroughly on all platforms yet. We appreciate your feedback and support and ask you to post details on any issues in the corresponding Jira ticket.

2. cqlsh 에러 처리(https://stackoverflow.com/questions/35197362/unable-to-open-cqlsh-apache-cassandra-importerror-no-module-named-cqlshlib)

다음과 같이 에러가 나오면 
---------------------------------------------------------------------------------------------------------

./cqlsh.py

Traceback (most recent call last):

  File "./cqlsh.py", line 168, in <module>

    from cqlshlib import cql3handling, cqlhandling, pylexotron, sslhandling, cqlshhandling

ImportError: No module named cqlshlib

cqlshlib 라이브러리를 찾을수 없다는 에러이다..

cqlsh.py 파일을 열어서 

---------------------------------------------------------------------------------------------------------

...
import sys
...
from uuid import UUID
sys.path.append("/usr/lib/python2.7/site-packages")  #cqlshlib  파일의 위치를 찾아서 넣어준다.
