反向代理
在計算機世界里,由于單個服務器的處理客戶端(用戶)請求能力有一個極限,當用戶的接入請求蜂擁而入時,會造成服務器忙不過來的局面,可以使用多個服務器來共同分擔成千上萬的用戶請求,這些服務器提供相同的服務,對于用戶來說,根本感覺不到任何差別。
nginx做前端代理分發,tomcat處理請求。nginx反代tomcat實現https有二個方法。
一、nginx配置https,tomcat也配置https

配置好后重新啟動nginx,tomcat,就可以https訪問了,這也是我現在采用的配置方式 。
二、nginx采用https,tomcat采用http

重啟nginx,tomcat,https就配置好了。
不管是第一種方法,還是第二種方法,如果通過http,直接訪問8001端口,瀏覽器都會提示你不安全的訪問,因為本身是http,確被重定向到了https。
