一.Nginx支持基于单个IP实现多域名的功能

　　Nginx支持基于单个IP实现多域名的功能，并且还支持单IP多域名的基础之上实现HTTPS，这一点Apache Httpd是不支持的，其实是基于Nginx的SNI（Server Name Indication）功能实现，SNI是为了解决一个Nginx服务器内使用一个IP绑定多个域名和证书的功能，其具体功能是客户端在连接到服务器建立SSL链接之前先发送要访问站点的域名（Hostname），这样服务器再根据这个域名返回给客户端一个合适的证书。

　　其实配置基于单个IP实现多域名的HTTPS方式也就是重复单个网站的https配置相应步骤。我的实验环境是在基于Nginx配置单个网站的https(博客链接:https://www.cnblogs.com/yinzhengjie/p/12052401.html),也就是上一次试验基础之上继续后续的步骤。

二.生成自签名证书

1>.生成"mobile.yinzhengjie.org.cn"网站使用的密钥对

三.Nginx证书配置

1>.查看主配置文件

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf/nginx.conf
worker_processes  4;
worker_cpu_affinity 00000001 00000010 00000100 00001000; 

events {
   worker_connections  100000;
   use epoll;
   accept_mutex on;
   multi_accept on;
}

   http {
     include       mime.types;

     default_type  text/html;

     charset utf-8;

     log_format my_access_json '{"@timestamp":"$time_iso8601",' '"host":"$server_addr",' '"clientip":"$remote_addr",' '"size":$body_bytes_sent,' '"responsetime":$request_ti
me,' '"upstreamtime":"$upstream_response_time",' '"upstreamhost":"$upstream_addr",' '"http_host":"$host",' '"uri":"$uri",' '"domain":"$host",' '"xff":"$http_x_forwarded_for",' '"referer":"$http_referer",' '"tcp_xff":"$proxy_protocol_addr",' '"http_user_agent":"$http_user_agent",' '"status":"$status"}';
    access_log logs/access_json.log my_access_json;

    ssl_certificate /yinzhengjie/softwares/nginx/certs/www.yinzhengjie.org.cn.crt;
    ssl_certificate_key /yinzhengjie/softwares/nginx/certs/www.yinzhengjie.org.cn.key;
    ssl_session_cache shared:sslcache:20m;
    ssl_session_timeout 10m;

    include /yinzhengjie/softwares/nginx/conf.d/*.conf;
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful

[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# 

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/https.conf
server {
    listen 80;
    listen 443 ssl;
    server_name www.yinzhengjie.org.cn;

    location / {
       root /yinzhengjie/data/web/nginx/static;
       index index.html;
    }
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok

[root@node101.yinzhengjie.org.cn ~]# 

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/https.conf

2>.编辑mobile的配置文件支持https功能

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/mobile.conf
server {
    listen 80;
    listen 443 ssl;
    server_name mobile.yinzhengjie.org.cn;

    ssl_certificate /yinzhengjie/softwares/nginx/certs/mobile.yinzhengjie.org.cn.crt;
    ssl_certificate_key /yinzhengjie/softwares/nginx/certs/mobile.yinzhengjie.org.cn.key;
    ssl_session_cache shared:sslcache:20m;
    ssl_session_timeout 10m;   

    location / {
       root /yinzhengjie/data/web/nginx/mobile;
       index index.html;
    }
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# 

3>.创建mobile网站的测试数据

[root@node101.yinzhengjie.org.cn ~]# mkdir -pv /yinzhengjie/data/web/nginx/mobile
mkdir: created directory ‘/yinzhengjie/data/web/nginx/mobile’
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# vim /yinzhengjie/data/web/nginx/mobile/index.html
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/data/web/nginx/mobile/index.html
<!doctype html>
<html lang="en">

    <meta charset="UTF-8" />
    <title>尹正杰的网页</title>

    <style type="text/css">

            color: yellow;
        }
    </style>

[root@node101.yinzhengjie.org.cn ~]# 

4>.重新加载nginx的配置文件

[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      9901     1  0 09:28 ?        00:00:00 nginx: master process nginx
nginx     9902  9901  0 09:28 ?        00:00:00 nginx: worker process

nginx     9904  9901  0 09:28 ?        00:00:00 nginx: worker process
nginx     9905  9901  0 09:28 ?        00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -s reload
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      9901     1  0 09:28 ?        00:00:00 nginx: master process nginx
nginx    24916  9901  4 10:41 ?        00:00:00 nginx: worker process
nginx    24917  9901  5 10:41 ?        00:00:00 nginx: worker process
nginx    24918  9901  5 10:41 ?        00:00:00 nginx: worker process
nginx    24919  9901  5 10:41 ?        00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]# 

5>.客户端浏览器分别访问"http://mobile.yinzhengjie.org.cn/"和"https://mobile.yinzhengjie.org.cn/"
