Le Huy Ha: Installing Python 2.7.10

Installing Python 2.7.10 - Django on CentOS 6

CentOS 6 still come with Python 2.6 and I need 2.7, below a simple tutorial how to achieve this with no pain and not messing with installed Python.

Update CentOS and install development tools

yum -y update

yum groupinstall -y 'development tools'

Also you need the packages below to enable SSL, bz2, zlib for Python and some utils:

1	yum install -y zlib-devel bzip2-devel openssl-devel xz-libs wget

Installing Python 2.7.8 from source

Download Python and extract it

# tar -xvf Python-2.7.8.tar

Installation process

Since we already installed all the dependencies we are ready to go:

# Enter the directory:

cd Python-2.7.10

# Run the configure:

./configure --prefix=/usr/local

# compile and install it:

make

make altinstall

# Checking Python version:

[root@nicetry ~]# python2.7 -V

Python 2.7.10

If you need set PATH variable check the line below:

export PATH="/usr/local/bin:$PATH"

Installing pip and virtualenv

Now we have Python installed, but something is missing isn’t? Yes! We need pip and virtualenv.

Install setuptools

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz

# Extract the files:

tar -xvf setuptools-1.4.2.tar.gz

cd setuptools-1.4.2

# Install setuptools using the Python 2.7.8:

python2.7 setup.py install

Installing pip

curl https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python2.7 -

And finally virtualenv

pip2.7 install virtualenv

And that’s all, we have Python 2.7.8 installed on CentOS.

And for Django

pip2.7 install django
