In centos6.5, the default Python version is 2.6.6. when I use the latest Django version, I find a syntax error! So I decided to upgrade Python. The steps are as follows:

1. install Python 2.7.10

1. Download

 

wget http://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz

After the download is complete:

2. extract

tar -xvf Python-2.7.10.tar

3. Compile/install

Create a new directory to use as the installation directory of Python2.7.10.

mkdir /usr/local/python2.7

Then start compiling

Cd Python-2.7.10 # enter the decompressed Python Directory

./Configure -- prefix =/usr/local/python2.7 # wait until compilation is complete

Make & make install # wait for installation

Here, even if Python 2.7.10 is installed, but now the Python version is still 2.6.6 in the command line:

 

Mv/usr/bin/python/usr/bin/python2.6 # Change the python name of the original version.

To use python, you need to add a new version of python. you can use soft links or add the bin directory of the new version of Python to the PATH.

ln -s /usr/local/python2.7 /usr/bin/python

Or

Vim/etc/profile add the following line export PATH = "/usr/local/python2.7/bin: $ PATH" save and exit source/etc/profile

Enter the python command line to see if the version is 2.7.10 !!!

II. install setuptools

Download:

<> There are multiple methods. here we will introduce one method:

 

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py

Download and get an ez_setup.py file to run it.

python ez_setup.py --insecure

Not surprisingly. Setuptools is successfully installed!

3. install pip

Download:

wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate

Unzip-install:

tar -xzvf pip-1.5.4.tar.gzcd pip-1.5.4python setup.py install

OK

IV. modify yum

If this step is not performed, yum will report an error

vim /usr/bin/yum

#! /Usr/bin/python changed to the one previously modified #! /Usr/bin/python2.6

Save and exit! OK

V. install MySQLdb

Use pip:

pip install MySQL-python

6. install Django

Pip install django or pip install Django = version
