反向代理
在计算机世界里,由于单个服务器的处理客户端(用户)请求能力有一个极限,当用户的接入请求蜂拥而入时,会造成服务器忙不过来的局面,可以使用多个服务器来共同分担成千上万的用户请求,这些服务器提供相同的服务,对于用户来说,根本感觉不到任何差别。
nginx做前端代理分发,tomcat处理请求。nginx反代tomcat实现https有二个方法。
一、nginx配置https,tomcat也配置https

配置好后重新启动nginx,tomcat,就可以https访问了,这也是我现在采用的配置方式 。
二、nginx采用https,tomcat采用http

重启nginx,tomcat,https就配置好了。
不管是第一种方法,还是第二种方法,如果通过http,直接访问8001端口,浏览器都会提示你不安全的访问,因为本身是http,确被重定向到了https。
