实战构建一个满足苹果要求的HTTPS后台服务

1.HTTPS基本概述

为什么需要使用HTTPS, 因为HTTP不安全
1.传输数据被中间人盗用, 信息泄露
2.数据内容劫持, 篡改

2.HTTPS配置语法

Syntax: ssl on | off;
Default: ssl off;
Context: http, server
Syntax: ssl_certificate file;
Default: —
Context: http, server
Syntax: ssl_certificate_key file;
Default: —
Context: http, server

3.HTTPS配置场景

配置苹果要求的证书
1.服务器所有连接使用TLS1.2以上版本(openssl 1.0.2)
2.HTTPS证书必须使用SHA256以上哈希算法签名
3.HTTPS证书必须使用RSA 2048位或ECC256位以上公钥算法
4.使用前向加密技术

秘钥生成操作步骤
1.生成key密钥
2.生成证书签名请求文件(csr文件)
3.生成证书签名文件(CA文件)

1.检查当前环境

//openssl必须是1.0.2
[root@Nginx ~]# openssl version
OpenSSL 1.0.2k-fips  26 Jan 2017
//nginx必须有ssl模块
[root@Nginx ~]# nginx -V
 --with-http_ssl_module

[root@Nginx ~]# mkdir /etc/nginx/ssl_key -p
[root@Nginx ~]# cd /etc/nginx/ssl_key

2.创建私钥

[root@Nginx ssh_key]# openssl genrsa -idea -out server.key 2048
Generating RSA private key, 2048 bit long modulus
.....+++
//记住配置密码, 我这里是1234
Enter pass phrase for server.key:
Verifying - Enter pass phrase for server.key:

3.生成使用签名请求证书和私钥生成自签证书

[root@Nginx ssl_key]# openssl req -days 36500 -x509 \
-sha256 -nodes -newkey rsa:2048 -keyout server.key -out server.crt
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:WH
Locality Name (eg, city) [Default City]:WH
Organization Name (eg, company) [Default Company Ltd]:edu    
Organizational Unit Name (eg, section) []:SA
Common Name (eg, your name or your server's hostname) []:bgx
Email Address []:bgx@foxmail.com

4.配置Nginx

[root@Nginx ~]# cat /etc/nginx/conf.d/ssl.conf
server {
    listen 443;
    server_name localhost;
    ssl on;
    index index.html index.htm;
    #ssl_session_cache share:SSL:10m;
    ssl_session_timeout 10m;
    ssl_certificate   ssl_key/server.crt;
    ssl_certificate_key  ssl_key/server.key;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
location / {
                root /soft/code;
                access_log /logs/ssl.log main;
        }
}

5.测试访问, 由于该证书非第三方权威机构颁发，而是我们自己签发的，所以浏览器会警告

6.以上配置如果用户忘记在浏览器地址栏输入https://那么将不会跳转至https, 需要将访问http强制跳转https

[root@Nginx ~]# cat /etc/nginx/conf.d/ssl.conf 
server {
    listen 443;
    server_name localhost;
    ssl on;
    index index.html index.htm;
    #ssl_session_cache share:SSL:10m;
    ssl_session_timeout 10m;
    ssl_certificate   ssl_key/server.crt;
    ssl_certificate_key  ssl_key/server.key;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
location / {
                root /soft/code;
        }
}
server {
        listen 80;
        server_name localhost;
        rewrite ^(.*) https://$server_name$1 redirect;
}

7.检查是否支持苹果要求ATS协议

//仅能在苹果终端上使用
$ nscurl --ats-diagnostics --verbose https://192.168.69.113

4.Https公有云实践

在云上签发各品牌数字证书，实现网站HTTPS化，使网站可信，防劫持、防篡改、防监听。并进行统一生命周期管理，简化证书部署，一键分发到云上产品。
