Oracle APEX 系列文章11:全站启用 HTTPS,让你的 APEX 更安全
原文地址:https://wangfanggang.com/Oracle/Oracle-APEX/apex-series-11/
引言目前主流的网站都要求 HTTPS 安全访问,Google Chrome 浏览器、微信内置浏览器打开非 HTTPS 的网页,都会提示不安全。如果做微信端开发,也是必须要 HTTPS 的网址才可以,可见 HTTPS 越来越重要了。 还不了解什么是 Oracle APEX,请阅读我的另一篇文章:Oracle APEX 系列文章1:Oracle APEX, 让你秒变全栈开发的黑科技 - Oracle APEX 系列文章2:在阿里云上打造属于你自己的APEX完整开发环境 (安装 CentOS)
- Oracle APEX 系列文章3:在阿里云上打造属于你自己的APEX完整开发环境 (安装 Tomcat, Nginx)
- Oracle APEX 系列文章4:在阿里云上打造属于你自己的APEX完整开发环境 (安装XE, ORDS, APEX)
- Oracle APEX 系列文章5:在阿里云上打造属于你自己的APEX完整开发环境 (进一步优化)
如果你按照钢哥之前的文章已经搭建好了 Oracle APEX 环境,那么你的应用架构应该如下图所示: 
这里简单回顾一下各部分组件的作用: - 用户在浏览器地址栏里输入URL,例如:https://apex.wangfanggang.com/ords/ (不要尝试打开这个网址了,我瞎写的)
- Nginx监听 HTTP ( 80) 端口和 HTTPS ( 443) 端口,如果请求的是静态文件(如:image, js 或者 css),则直接获取 /i/目录中的内容,对于其他动态请求(如:APEX请求),进一步转发至后端 Tomcat 服务器做进一步处理。
- Tomcat 服务器接收到请求后,会查找部署在它上面的应用,就是我们之前部署的 ORDS应用;
- 如果是 APEX 请求,ORDS 进一步将请求转发给 APEX (Oracle 数据库) 进行处理;如果是 ORDS 请求,自身进行处理;
原理比较简单,而我们要做的就是在 Nginx 层面讲 HTTP 请求转发到 HTTPS 上,进而实现全站 HTTPS 访问。 申请 SSL 证书这里以在阿里云上购买免费 SSL 证书为例,首先登录阿里云控制台,进入 安全(云盾)->SSL证书(应用安全),点击 购买证书。 
进入到选择购买页面,提示1年需要五千多大洋,土豪直接点击付款即可。 
好吧,我是穷人,只能看看有没有免费证书。其实是有的,依次点击 Symantec -> 1个域名 -> 免费型DV SSL,成功激活30人 
接下来回到控制台,补全刚刚申请的证书信息。 
按照提示补全信息。 钢哥提示:由于我们申请的是阿里云的免费证书,只能作用于一个固定域名,一般我们都不会把主域名用来放置APEX应用,所以这里可以填写诸如:apex.xxx.com 的二级域名。如果你想要免费通配符域名,可以移步这里:使用Let’s Encrypt给网站加上免费HTTPS证书 另外需要注意的是,第二步的验证环节,如果你选择的是文件验证,请一定按照提示把对应的验证文件放到你的服务器上, 正常文件验证一般不会超过5分钟,如果长时间没验证通过,一定是你操作有问题了。
当你的证书申请通过后,就可以点击 下载链接了。 配置 Nginx将 SSL 证书添加进 nginx.conf,按照 下载证书页面的提示配置 Nginx: 我的 nginx.conf文件内容如下: - worker_processes auto;
- worker_rlimit_nofile 10000;

配置完 nginx,别忘了重启令配置生效。再次在浏览器中访问 APEX 页面,如果能看到如下界面,恭喜你,你的 SSL 证书生效了!! 配置 Tomcat钢哥在配置的时候 SSL 证书时遇到了一个奇怪的问题,就是启用 SSL 证书后,访问 APEX 页面时会发生重定向错误( 302error:too_many_redirects),导致无法正常访问。 
经过跟同事几天的研究,发现除了要在 Nginx 上启用 SSL 证书以外,还必须在 Tomcat 上也启用。还是回到阿里云控制台证书下载页面,找到 Tomcat 配置证书部分。 钢哥提示:特别要注意的是,这里要选择 JKS格式证书进行安装,否则会有问题。

在 Tomcat 的 server.xml文件中添加如下内容: - <Valve
- className = "org.apache.catalina.valves.RemoteIpValve"
- remoteIpHeader = "X-Forwarded-For"
- protocolHeader = "X-Forwarded-Proto"
- />
