A memo with Python2.7 and Python3 on CentOS

Since Python 2.6 is included in the standard of CentOS 6.5 and Python 2.7 is included in CentOS 7.2, there are various inconveniences, so install a new version and a frequently used version.

The installation destination is / opt / local.

** Addendum **

2020/01/10 Addendum: Let's use sloppy Python3.

Install Developer Tools

# yum groupinstall "Development tools"
# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel

Python 2.7, 3.6 install

First download and install them.

curl -O https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
curl -O https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
tar zxf Python-3.6.6.tgz 
tar zxf Python-2.7.6.tgz 

Install Python2.7

cd Python-2.7.6
./configure --prefix=/opt/local
make && make altinstall

Install Python3.6

cd Python-3.6.6
./configure --prefix=/opt/local
make && make altinstall

Have Easy_install installed

(2015/07/19: Change the link destination of distribute. Thanks @ mtomoaki_96kg: +1 :)

curl -O https://pypi.python.org/packages/source/d/distribute/distribute-0.6.49.tar.gz
tar xzf distribute-0.6.49.tar.gz
cd distribute-0.6.49
/opt/local/bin/python2.7 ./distribute_setup.py 
/opt/local/bin/python3.3 ./distribute_setup.py 

2015/07/19 Addendum: PIP can be installed without installing distribute / setuptools, so you can skip this step without any problem. Rather, you can install it by running the command pip install distribute with pip.

see: https://pypi.python.org/pypi/distribute/0.6.49

Install PIP

(Added on 2014/09/27) (2015/04/22 changed from raw.github.com to raw.githubusercontent.com) (2015/07/19 Changed from github to pypa link see: https://pip.pypa.io/en/latest/installing/#install-pip)

> curl -kL https://bootstrap.pypa.io/get-pip.py | /opt/local/bin/python2.7
> curl -kL https://bootstrap.pypa.io/get-pip.py | /opt/local/bin/python3.6

Install VirtualEnv

/opt/local/bin/pip2.7 install virtualenv
/opt/local/bin/pip3.6 install virtualenv 

thanks sahiruha: +1:


--http://www.petitec.com/2013/04/ Put python2-7 in centos6 /
