Enter the extracted folderCD Python-3.3.0

4, build a folder in/usr/local before compiling Python3 (as a Python installation path, so as not to overwrite the old version)Mkdir/usr/local/python3 (new folder here with mkdir, if new file is Touch)5, start compiling the installation (the author installs the minimum CentOS system, so before using the compile command, you must install the compilation Suite gcc, if the reader installs the interface CentOS system, or the use of the compiler tool can skip the installation of GCC, directly below the compilation steps)./configure--prefix=/usr/local/python3

Make

Make Install6, at this time does not overwrite the old version, and then the original/usr/bin/python link changed to another name (the author retains two versions of, a python, a python3, so the 6th step of the author skipped, the 7th step of the link after the name changed to Python3, the reader can follow the normal steps, Achieve the same effect)mv/usr/bin/python/usr/bin/python_old27. Create a new version of the Python linkln-s/usr/local/python3/bin/python3/usr/bin/python8. Enter at this timepython-v10.
