You can view the location, usually under the / usr/bin/python directory.

Here is how to install python3

Install the dependency package first

Yum-y groupinstall "development tools" yum-y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

Then download different versions of python3 according to your own needs. I downloaded python3.6.2.

Wget https://www.python.org/ftp/python/3.6.2/python-3.6.2.tar.xz

If the speed is not fast enough, you can download it directly from the official website and transfer it to the specified location on the server using software such as winscp. My storage directory is / usr/local/python3. Use the command:

Mkdir / usr/local/python3

Create an empty folder

Then extract the package, enter the directory, and install python3

Tar-xvjf python-3.6.2.tar.xzcd python-3.6.2./configure-- prefix=/usr/local/python3make & & make install

Finally, create a soft link

Ln-s / usr/local/python3/bin/python3 / usr/bin/python3ln-s / usr/local/python3/bin/pip3 / usr/bin/pip3

Enter the python3 test on the command line
