Solution to install Python 2.7 on CentOS6

On CentOS6, the yum installation tool is based on Python 2.6.6, so the default installation on CentOS6 is Python 2.6.6, because the production environment is deployed on the server system for CentOS6, but the code is written based on Python 2.7, and all problems are encountered.

After finding that the system cannot uninstall Python 2.6, check the system version number

cat /etc/*-release

I found that the system version is CentOS6, so I started Google search to solve it.

Solution

Reinstall Python 2.7 manually

Preparation phase

# Start by making sure your system is up-to-date:
yum update
# Compilers and related tools:
yum groupinstall -y "development tools"
# Libraries needed during compilation to enable all features of Python:
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel
# If you are on a clean "minimal" install of CentOS you also need the wget tool:
yum install -y wget

Install Python

Download python2.7 and install

# Get Python 2.7.14:
wget /ftp/python/2.7.14/Python-2.7.
tar xf Python-2.7.
cd Python-2.7.14
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall

Install Pip

# First get the script:
wget /
# Then execute it using Python 2.7
python2.7 
# With pip installed you can now do things like this:
pip2.7 install [packagename]
pip2.7 install --upgrade [packagename]
pip2.7 uninstall [packagename]

Create a virtual environment

Finally, you can use venv to create a virtual environment (after all, you cannot uninstall Python 2.6)

# Install virtualenv for Python 2.7 and create a sandbox called my27project:
pip2.7 install virtualenv
virtualenv my27project
Try it？
# Check the system Python interpreter version:
python --version
# This will show Python 2.6.6
# Activate the my27project sandbox:
source my27project/bin/activate
# This will show Python 2.7.4
python --version
