最近弄了个 DigitalOcean 的 VPS 玩，照葫芦画瓢搭了个简单的 nginx server 和 discourse 论坛。 有需要的同学可以参考我的笔记。顺带一个 DO 的邀请码 :)

笔记摘要：

Deploy An Nginx Server
======================

Refer to official site:
http://wiki.nginx.org/Install

Brief:
apt-get install nginx

To control: nginx -s [ stop | quit | reopen | reload ]

Configuration files are placed in /etc/nginx/:
sites-enabled/ and conf.d/* will be included in nginx.conf
And sites-available/ is used for customization, linked as symbol into sites-enabled/.

1. Basic http server example
2. Basic forward proxy example

Deploy A Docker for Discourse on DO
===================================

Refer to official tutorial:
https://github.com/discourse/discourse/blob/master/docs/INSTALL-digital-ocean.md
To use it along with Nginx, we need below extra steps since default 80 port is occupied already:
1. Modify /var/docker/containers/app.yml
## which TCP/IP ports should this container expose?
expose:
- "4578:80" # fwd host port 4578 to container port 80 (http)
- "2222:22" # fwd host port 2222 to container port 22 (ssh)
2. Add a conf for Nginx to tell him to forward specific request to port 4578.
