Nginx ssl offload for Tomcat in SmartOS
本篇的目的主要在使用Nginx Reverse Proxy的功能來卸載HTTPS SSL
也就是說Tomcat走HTTP 8080 Port，本身無HTTPS SSL
然後透過Nginx來加上HTTPS SSL，提供HTTPS服務於443 Port上
環境以MiCloud SmartOSPlus64為主
Environment
# uname -a
SunOS MiCloudDBT.local 5.11 joyent_20120808T224832Z i86pc i386 i86pc Solaris
Installation
# pkgin -y in nginx-1.0.4 apache-tomcat-6.0.32 sun-jdk6-6.0.26
Servers
Tomcat server: 123.123.123.123 (Port: 8080)
Nginx server: 123.123.123.123 (Port: 80, 443)
Nginx Configure (/opt/local/etc/nginx/nginx.conf)
# 說明 - 此部份設定主要包含：
# 1. 建立tomcat - nginx upstream設定
# 2. 設定Nginx https server over 443 port，並指定ssl key
# 3. 設定欲轉址的Tomcat context(ex: http://123.123.123.123:8080/examples/ --> https://123.123.123.123/examples/)
# ps: http 80段落的設定(紫色)，是強制將http 80的所有request轉導至https，必須有這個設定，不然每個tomcat的link都會被導到http而非https

<!--
設定tomcat 8080 port的reverse proxy轉導的port
如設定port number，則不會直接轉到該port，而不會有協定上的改變(ex: 會變成 http://123.123.123.123:443/examples)
如設定https，則可以直接走預設443 port的HTTPS SSL
