VirtualBoxのインストールと、Vagrantをインストールし、CentOS7を動かしてみましたので、今回は、Python3.6をインストールしてみます。
■Vagrantにログインする
まず、Windows10の検索ボックスで「cmd」と検索して「コマンドプロンプト」を起動します。
起動後、Vagrantへのログインを試みます。
vagrant up
ログインを試みるために、上記のコマンドを入力し、Enterキーを押します。
Bringing machine ‘default’ up with ‘virtualbox’ provider…
==> default: Checking if box ‘centos/7’ version ‘2004.01’ is up to date…
==> default: Clearing any previously set forwarded ports…
==> default: Fixed port collision for 22 => 2222. Now on port 2200.
==> default: Clearing any previously set network interfaces…
==> default: Preparing network interfaces based on configuration…
default: Adapter 1: nat
==> default: Forwarding ports…
default: 22 (guest) => 2200 (host) (adapter 1)
==> default: Booting VM…
==> default: Waiting for machine to boot. This may take a few minutes…
default: SSH address: 127.0.0.1:2200
default: SSH username: vagrant
default: SSH auth method: private key
default: Warning: Connection reset. Retrying…
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM…
default: No guest additions were detected on the base box for this VM! Guest
default: additions are required for forwarded ports, shared folders, host only
default: networking, and more. If SSH fails on this machine, please install
default: the guest additions and repackage the box to continue.
default:
default: This is not an error message; everything may continue to work properly,
default: in which case you may ignore this message.
==> default: Rsyncing folder: /cygdrive/c/Users/user/ => /vagrant
Enterキーを押すと、仮想マシン（CentOS7）が起動します。
vagrant ssh
起動後、Vagrantにログインするために、上記のコマンドを入力し、Enterキーを押します。
[vagrant@localhost ~]$
Enterキーを押すと、ログインが成功します。
■CentOS7にリポジトリを追加
ログインした後は、IUS Community Projectを利用してCentOS7にリポジトリを追加します。CentOS7のデフォルトのリポジトリでは、Python3.6が提供されていません。
[vagrant@localhost ~]$ sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm
追加するために、上記のコマンドを入力し、Enterキーを押します。
Loaded plugins: fastestmirror
Cannot open: https://centos7.iuscommunity.org/ius-release.rpm. Skipping.
Error: Nothing to do
Enterキーを押すと、Errorが発生した。原因を調べてみると、iusの最新リンクが変更になったということなので、リンクを変更する。
[vagrant@localhost ~]$ sudo yum install -y https://repo.ius.io/ius-release-el7.rpm
リンクを変更すると上記のコマンドとなり、入力し、Enterキーを押します。

■Python3.6を実行する
インストールが完了しましたので、Python3.6を実行してみます。
[vagrant@localhost ~]$ python3.6
実行するためには、上記のコマンドを入力し、Enterキーを押します。
Python 3.6.8 (default, Apr 2 2020, 13:34:55)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux
Type “help”, “copyright”, “credits” or “license” for more information.
>>>
Enterキーを押すと、Python3.6の対話モードになります。対話モードになりましたので、print関数を使ってテストしてみます。
>>> print(‘こんにちは’)
こんにちは
>>>
テストしてみると、print関数で設定した文字列の値を出力することができました。
