Installing Python3.5 under CentOS 7

wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz

• Unzip the tgz package

TAR-ZXVF python-3.5.1.tgz

• Move Python below the/usr/local

MV Python-3.5.1/usr/local

Ll/usr/bin | grep python

Rm-rf/usr/bin/python

• Compile, install

Make install

• Delete old soft links to create new soft link to latest Python

Rm-rf/usr/bin/python

Ln-s/usr/local/bin/python3.5/usr/bin/python

Python-v

Because Yum uses python2, it may not work properly after replacing with Python3, and continue to use this python2.7.5

Therefore, modify the Yum configuration file (sudo vi/usr/bin/yum). Change the #!/usr/bin/python of the file head to #!/usr/bin/python2.7 save exit

Enjoy your python!
