Installing Python 3 under CentOS 6

Can download each version of the python:https://www.python.org/ftp/python/configuration installation

Download the latest installation package (as of 2013/11/05) or version 3.3.2.

#wget http://python.org/ftp/python/3.5.2//Python-3.5.2.tgz#tar xzf Python-3.5.2.tgz#cd Python-3.5.2#./configure --prefix=/opt/apps/python3#make#make install

If prefix is not specified, it is installed by default under/usr/local, so it can be found in path. We want to install a version that can be copied and installed, so it is installed in the specified directory.

Setting up the environment

/opt/apps/python3/bin can be added to the system environment variable,

#echo ‘export PATH=$PATH:/opt/apps/python3/bin‘ >> ~/.bash_profile

And we are easy to set up soft links more convenient

#ln -s /opt/apps/python3/bin/python3 /usr/bin

Confirm Installation Success

# python3 -VPython 3.5.2

Install PIP

PIP is convenient for installing dependent software, so it is recommended to install.

#wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - |python3#wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py -O - |python3#ln -s /opt/apps/python3.5/bin/pip-3.5 /usr/bin/

Install required third-party libraries

such as Mysql-connector and requests

#pip-3.5 install mysql-connector-python#pip-3.5 install requests

If the following error occurs when you install PIP:

ImportError: No module named bz2

This indicates that the installed Python 3 is missing a dependent library bzip2-devel and needs to install the dependent libraries before compiling the installation.
