Upgrade CentOS python for 2.7 (CentOS python upgrade)

1, first download Python 2.7.8 version of the TAR package. Why not choose the latest version of 3.4? Because the compatibility of version 3 is not good. A number of mature projects have been developed based on 2.7.

https://www.python.org/download/

After the download is found, it is uploaded to the server via the Linux RZ command, and you can also download it from the command wget.

2. The default download address is the home address of the current user. Next

TAR-XVF python-2.7.8. Tar

After decompression, enter the directory

CD  python-2.7.  8

Build a folder in/usr/local before compiling python27 (as a Python installation path to avoid overwriting the old version)

cd/usr//usr/local/python3
CD ~

Start compiling the installation

1 ./configure--prefix=/usr/local/python323make45 Make install

It will take a few minutes and wait patiently

After that, put the previous backup under.

Mv/usr/bin/python/usr/bin/python_old

To create a new version of the link

Ln-s/usr/local/python27/bin/python2.7/usr/bin/python

Ok

Look again at the next
