Centos6 upgrades the python version to 2.7 and replaces yum

1. Download the installation package

cd /usr/local/src 
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar -zxvf Python-2.7.13.tgz

2. Compile

cd Python-2.7.13
./configure --prefix=/usr/local/python27
make && make install

3. Replace the old version

mv /usr/bin/python /usr/bin/python_old
ln -s /usr/local/python27/bin/python2.7 /usr/bin/python
/usr/bin/python

4. Modify the python source that yum relies on to avoid yum being unavailable

vi /usr/bin/yum

Change the first line #!/usr/bin/python to #!/usr/bin/python2.6 or #!/usr/bin/python_old
