1. Install the compilation environment package (to prevent installation errors) yum install gcc-c++ gcc make cmake zlib-devel bzip2-devel openssl-devel ncurse-devel-y yum install libffi-devel-y2. Download Python3.7 source code package online # enter tmp directory cd / tmp # download python3.7.0

3. Extract and configure # extract tar Jxvf Python-3.7.0.tar.xz # enter python3.7.0 directory cd Python-3.7.0 # create directory mkdir-p / usr/local/python3 # configuration (specify installation directory). / configure-prefix=/usr/local/python3-enable-optimizations

4. Compile and install make & & make install5. Replace the system default Python version 1). Back up the old version of the original system python

Mv / usr/bin/python / usr/bin/python.bak2). Create a soft link for a new version of Python3.7

Ln-s / usr/local/python3/bin/python3.7 / usr/bin/python3). View Python version

Python-V6. Modify yum function because the function of yum depends on Pyhon2, now changing the default Python version will cause yum not to work properly, so make the following fixes

Vim / usr/bin/yum change / usr/bin/python to / usr/bin/python2.7

Vim / usr/bin/yum-config-manager (you can skip this step if centos cannot find it) change / usr/bin/python to / usr/bin/python2.7

Vim / usr/libexec/urlgrabber-ext-down change / usr/bin/python to / usr/bin/python2.7

Then re-execute the yum command
