Linux CentOS Upgrading Python 3.6

Because the software environment requires a higher version of python, CentOS6 is 2.6 by default, CentOS7 is version 2.7. By the way, some netizens mentioned that Seafile cloud disk cannot be installed in CentOS6 One button package Because Python 2.7 is the minimum version by default. In this article, a software debugged by Lao Zuo requires Python 3 or above, so I'm going to install Python 3.6.

Note: It is recommended that users we are not familiar with should not install directly in the production environment. You can first install in the test environment to see if it is feasible.

First, install the prerequisite environment package

yum -y groupinstall development zlib zlib-devel

Second, download and Install python 3.6

wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
tar xJf Python-3.6.0.tar.xz
cd Python-3.6.0
./configure
make
make install

Third, check whether it is successful

which python3
python3 -V

Fourth, create soft links

cd /usr/bin
mv python python.backup
ln -s /usr/local/bin/python3 /usr/bin/python

Then we restart the machine and see if the current python is 3.6

In this way, python can be upgraded and installed to version 3.6.
