nginx实现https网站设置（SSL证书生成配置）

一、HTTPS简介
1.https简介
HTTPS其实是有两部分组成：HTTP + SSL / TLS，也就是在HTTP上又加了一层处理加密信息的模块。服务端和客户端的信息传输都会通过TLS进行加密，所以传输的数据都是加密后的数据
2.https协议原理
首先，客户端与服务器建立连接，各自生成私钥和公钥，是不同的。服务器返给客户端一个公钥，然后客户端拿着这个公钥把要搜索的东西加密，称之为密文，并连并自己的公钥一起返回给服务器，服务器拿着自己的私钥解密密文，然后把响应到的数据用客户端的公钥加密，返回给客户端，客户端拿着自己的私钥解密密文，把数据呈现出来
二、证书和私钥的生成
注意：一般生成的目录,应该放在nginx/conf/ssl目录
1.创建服务器证书密钥文件 server.key：
openssl genrsa -des3 -out server.key 1024
输入密码，确认密码，自己随便定义，但是要记住，后面会用到。
2.创建服务器证书的申请文件 server.csr
openssl req -new -key server.key -out server.csr
输出内容为：
Enter pass phrase for root.key: ← 输入前面创建的密码 
Country Name (2 letter code) [AU]:CN ← 国家代号，中国输入CN 
State or Province Name (full name) [Some-State]:BeiJing ← 省的全名，拼音 
Locality Name (eg, city) []:BeiJing ← 市的全名，拼音 
Organization Name (eg, company) [Internet Widgits Pty Ltd]:MyCompany Corp. ← 公司英文名 
Organizational Unit Name (eg, section) []: ← 可以不输入 
Common Name (eg, YOUR name) []: ← 此时不输入 
Email Address []:admin@mycompany.com ← 电子邮箱，可随意填
Please enter the following ‘extra’ attributes 
to be sent with your certificate request 
A challenge password []: ← 可以不输入 
An optional company name []: ← 可以不输入
4.备份一份服务器密钥文件
cp server.key server.key.org
5.去除文件口令
openssl rsa -in server.key.org -out server.key
6.生成证书文件server.crt
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
    三、配置文件

1.下面为配置文件 /usr/local/nginx/conf/vhost/daj.conf

server{
#比起默认的80 使用了443 默认 是ssl方式  多出default之后的ssl
        listen 443 default ssl;
#default 可省略
#开启  如果把ssl on；这行去掉，ssl写在443端口后面。这样http和https的链接都可以用
        ssl on;
#证书(公钥.发送到客户端的)
        ssl_certificate ssl/server.crt;
#私钥,
        ssl_certificate_key ssl/server.key;
#下面是绑定域名
        server_name www.daj.com;
        location / {
#禁止跳转
        proxy_redirect off;
#代理淘宝
proxy_pass https://www.tao.com/;  
        }        
}

 
四、开启nginx的ssl模块
1.the "ssl" parameter requires ngx_http_ssl_module  in /usr/local/nginx/conf/nginx.conf:37
原因是nginx缺少http_ssl_module模块，编译安装时带上--with-http_ssl_module配置就可以了
2.如果已经安装过nginx,想要添加模块看下面
1)切换到nginx源码包
cd /usr/local/src/nginx-1.11.3
2)查看ngixn原有的模块
/usr/local/nginx/sbin/nginx -V
3)重新配置
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
4)重新编译，不需要make  install安装。否则会覆盖
make
5)备份原有已经安装好的nginx
cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
6)将刚刚编译好的nginx覆盖掉原来的nginx(ngixn必须停止)
cp ./objs/nginx /usr/local/nginx/sbin/ 
这时，会提示是否覆盖，请输入yes，直接回车默认不覆盖
7)启动nginx，查看nginx模块，发现已经添加
/usr/local/nginx/sbin/nginx -V
