1. Use PuTTY to log in to the server as the root user.
2. Decompress the source package and go to the directory.

   tar -xvf Python-3.9.6.tgz
   cd Python-3.9.6

3. Install the dependencies.

   yum install gcc libffi* openssl libssl zlib* bzip2

4. Perform the compilation and installation.

   ./configure --prefix=/path/to/python3.9.6 --enable-shared --enable-optimizations
   make
   make install

5. Set the environment variables.

   export PATH=/path/to/python3.9.6/bin:$PATH
   export LD_LIBRARY_PATH=/path/to/python3.9.6/lib:$LD_LIBRARY_PATH
