Installation: Clarify Python 3 on CentOS #78
Conversation
CentOS 7 has Python 3.6 in the official repositories since some time. This allows us to get an almost modern Python interpreter onto the system without fiddling with PATH environment varible like SCL does.

Hello, The current CentOS installation docs reflect changes recommended by #31, #62, some Gitter/Telegram chats from CentOS users, as well as my own (later) tests with CentOS 7. Now, I'm not a frequent CentOS user as you can probably tell, so I'm not 100% certain which packages are required under which circumstances. I do want the docs to be easy and accurate, though.
Does this mean that there was a recent-ish change to the CentOS repositories, perhaps after the docs changes in #31/#62, which means we can update the docs? Just want to make sure I fully understand. Thanks! |

If I remember it correctly, back in the days when CentOS 7 was released, it had no python 3 version. Python 3.4 was available via EPEL. Later Python 3.6 was introduced (to EPEL I think, and later moved to base). However, the package It's available since march 2019. It's just not installed by default and the /usr/bin/python symlink always points to python 2 on CentOS 7. That might confuse people. |

I did some digging into the old centos 7 releases. their 7.5.1804 release did not contain python3 in the main repos: http://vault.centos.org/7.5.1804/cr/x86_64/Packages/ after that it got moved from epel to the base repo and is available since 7.6.1810: http://vault.centos.org/7.6.1810/cr/x86_64/Packages/ |

Description
This PR just updates the installation instructions for CentOS. Since they have now Python 3.6 in the base repo, we can simply rely on that instead of adding another repo. While I'm not against more repos, SCL in particular can get a bit tricky because of their setup.

Motivation and Context
Make SCL optional
Tests
Since this is just a docs change, I didn't touch any tests. Of course I tried this locally an can confirm that the base repo ships python3.6 and that hyperglass works with that.
