nginxでproxyサーバを立てる

mac上のvirtualboxにvagrantでubuntuサーバを2台たて、両方にnginxをインストール。

1台はweb server、もう1台はsslのproxy serverとする。

そうすると、proxy serverにhttpsアクセスすると、web serverのhttpページが表示される。

virtual boxをインストールされているところから。

■vagrantをインストールする。

% vagrant --version
Vagrant 1.9.6

■vmを立てる
□1台目

% cd
% mkdir vagrant_work
% cd vagrant_work
% vagrant init ubuntu/trusty64

A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

% vagrant up --provider virtualbox
