[root@sankar-devops]#cd /opt

[root@sankar-devops opt]#wget http://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz  

[root@sankar-devops opt]#xz -d Python-2.7.8.tar.xz  

[root@sankar-devops opt]#tar -xvf Python-2.7.8.tar 

Step3: [root@sankar-devops opt]# cd Python-2.7.8
[root@sankar-devops Python-2.7.8]# ./configure --prefix=/usr/local

Put the below line in ~/.bashrc file:

[root@sankar-devops]#vim ~/.bashrc
alias python=/usr/local/bin/python2.7


Now execute the command:

[root@sankar-devops]#source ~/.bashrc

Kafka Module installation on Python 2.7.x

[root@sankar-devops]#cd /usr/local/lib/python2.7/site-packages

[root@sankar-devops]#cd /usr/lib/python2.6/

[root@sankar-devops]#cp -r kafka /usr/local/lib/python2.7/site-packages/

[root@sankar-devops]#cp -r kafka_python-1.4.4.dev-py2.6.egg-info/  /usr/local/lib/python2.7/site-packages/

[root@sankar-devops]#cp -r pip*  /usr/local/lib/python2.7/site-packages/

Step6: Verification
[root@sankar-devops]# python
