Centos python upgrade 2.7.3

First download the source tar package

You can use the built-in linux download tool wget to download, as shown below:

wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

After the download is complete, go to the download directory and decompress the package.

tar -zxvf Python-2.7.3.tgz

Enter the decompressed folder

cd Python-2.7.3

Create a folder python27 in/usr/local before compilation (as the python installation path to avoid overwriting the old version)

mkdir /usr/local/python2.7.3

Compile and install the package in the decompressed directory

./configure --prefix=/usr/local/python2.7.3makemake install

In this case, the old version is not overwritten, and the original/usr/bin/python link is changed to another name.

mv /usr/bin/python /usr/bin/python_old

Create a link to the new version of python.

ln -s /usr/local/python2.7.3/bin/python2.7 /usr/bin/python

ln -s /usr/local/python2.7.3/bin/python2.7 /usr/bin/python2.7

Enter

python

The new version of python is displayed.
