nginx的https协议需要ssl模块的支持，我们在编译nginx时使用--with-http_ssl_module参数加入SSL模块。还需要服务器私钥，服务器证书，如果是公司对外环境，这个证书需要购买第三方的权威证书，否则用户体验得不到保障。

[root@WZKX-WEB01 key]# openssl req -new -key server.key -out server.csr
说明：这是用步骤1的密钥生成证书请求文件server.csr, 这一步提很多问题，一一输入
Enter pass phrase for server.key:
You are about to be asked to enter information thatwill be incorporated
into your certificate request.
What you are about to enter is what is called aDistinguished Name or a DN.
There are quite a few fields but you can leave someblank
For some fields there will be a default value,
If you enter ‘.’, the field will be left blank.

说明：这是用步骤1,2的的密钥和证书请求生成证书server.crt。 【-days参数指明证书有效期，单位为天】
[root@WZKX-WEB01key]# pwd

[root@WZKX-WEB01key]# ls
server.crt server.csr server.key server.key.ori
[root@WZKX-WEB01 key]# cat /application/nginx/conf/nginx.conf
server {
ssl on;
ssl_certificate /application/nginx/conf/key/server.crt;
ssl_certificate_key /application/nginx/conf/key/server.key;
listen 443;
server_name www.miaomiao.com;
location /{
root /opt/web/www.miaomiao.com;
index index.html index.htm;
}
}
[root@WZKX-WEB01 key]# /application/nginx/sbin/nginx -s reload
[root@WZKX-WEB01 key]# netstat -lntup|grep 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 11404/nginx
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，如果是对外的业务需要加密，必须使用商用第三方签名证书
以上配置有个不好的地方，如果用户使用时忘了使用https或者443端口，那么将会报错，所以我们需要80端口的访问转到443端口并使用ssl加密访问。【生产环境中，用户也基本不可能用https去访问一个网站，所以实现跳转很有必要。】
只需要增加一个server段，使用301永久重定向。
