前言：
在安全至上的今天，全站https的口号日趋高涨；
**ngx_http_ssl_module模块相关的配置**
ssl_certificate file;指明证书路径
ssl_certificate_key file;证书对应的私钥文件；
ssl_ciphers ciphers;指明由nginx使用的加密算法，可以是OpenSSL库中所支持的各种加密套件；
ssl_protocols [SSLv2][SSLv3][TLSv1.1][TLSv1.2];指明使用的SSL协议版本；默认为后三个；
ssl_session_cahce off|none|[builtin[:size]][shared:name:size];指明ssl会话缓存机制；
builtin：使用openssl内置的ssl会话缓存。各worker私有；
shared：在各worker之间使用一个共享的缓存；
name：独有名称；
size：缓存空间大小
ssl_session_timeout time;ssl会话超时时长；即ssl session cache中的缓存有效时长；
**创建私有CA**
[root@node3 ~]# (umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.‘, the field will be left blank.

**配置nginx为https**
server {
listen 443 ssl;
listen 172.16.61.4:80;
server_name www.tz.com;
root /data/www/vhost1;
ssl_certificate /etc/nginx/ssl/nginx.crt;
ssl_certificate_key /etc/nginx/ssl/nginx.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
if ($scheme = http) { #强制将http请求重定向至https
return 301 https://$server_name$request_uri;
}
}注：生产环境中，需要将自己生成的私钥文件和证书请求文件copy到CA机构，并由CA机构向你进行证书的签发，之后就可以使用这些证书；
