下面是详细的配置(Nginx 端口 80/443,Tomcat 的端口 8080):
Nginx 这一侧的配置没什么特别的:
upstream tomcat { server 127.0.0.1:8080 fail_timeout=0; } # HTTPS server server { listen 443 ssl; server_name localhost; ssl_certificate /Users/winterlau/Desktop/SSL/oschina.bundle.crt; ssl_certificate_key /Users/winterlau/Desktop/SSL/oschina.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-Proto https; proxy_redirect off; proxy_connect_timeout 240; proxy_send_timeout 240; proxy_read_timeout 240; # note, there is not SSL here! plain HTTP is used proxy_pass http://tomcat; } }
其中最为关键的就是 ssl_certificate 和 ssl_certificate_key 这两项配置,其他的按正常配置。不过多了一个 proxy_set_header X-Forwarded-Proto https; 配置。
最主要的配置来自 Tomcat,下面是我测试环境中的完整 server.xml:
<?xml version='1.0' encoding='utf-8'?> <Server port="8005" shutdown="SHUTDOWN"> <Service name="Catalina"> <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" proxyPort="443"/> <Engine name="Catalina" defaultHost="localhost"> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="x-forwarded-for" remoteIpProxiesHeader="x-forwarded-by" protocolHeader="x-forwarded-proto" /> <Context path="" docBase="/oschina/webapp" reloadable="false"/> </Host> </Engine> </Service> </Server>
上述的配置中没有什么特别的,但是特别特别注意的是必须有 proxyPort="443",这是整篇文章的关键,当然 redirectPort 也必须是 443。同时 <Value> 节点的配置也非常重要,否则你在 Tomcat 中的应用在读取 getScheme() 方法以及在 web.xml 中配置的一些安全策略会不起作用。
