1、Http與Https的區別
HTTP：是互聯網上應用最爲普遍的一種網絡協議，是一個客戶端和服務器端請求和應答的標準（TCP），用於從WWW服務器傳輸超文本到本地瀏覽器的傳輸協議，它可使瀏覽器更加高效，使網絡傳輸減小。php

HTTPS：是以安全爲目標的HTTP通道，簡單講是HTTP的安全版，即HTTP下加入SSL層，HTTPS的安全基礎是SSL，所以加密的詳細內容就須要SSL。HTTPS協議的主要做用能夠分爲兩種：一種是創建一個信息安全通道，來保證數據傳輸的安全；另外一種就是確認網站的真實性。html

HTTPS和HTTP的區別主要以下：
一、https協議須要到ca申請證書，通常免費證書較少，於是須要必定費用。
二、http是超文本傳輸協議，信息是明文傳輸，https則是具備安全性的ssl加密傳輸協議。
三、http和https使用的是徹底不一樣的鏈接方式，用的端口也不同，前者是80，後者是443。
四、http的鏈接很簡單，是無狀態的；HTTPS協議是由SSL+HTTP協議構建的可進行加密傳輸、身份認證的網絡協議，比http協議安全。node


2、使用openssl生成證書
openssl是目前最流行的SSL密碼庫工具，其提供了一個通用、健壯、功能完備的工具套件，用以支持SSL/TLS協議的實現。nginx

好比生成到：/usr/local/sslweb

openssl req -x509 -nodes -days 36500 -newkey rsa:2048 -keyout /usr/local/ssl/nginx.key -out /usr/local/ssl/nginx.crt
生成過程：

# openssl req -x509 -nodes -days 36500 -newkey rsa:2048 -keyout /u sr/local/ssl/nginx.key -out /usr/local/ssl/nginx.crt
Generating a 2048 bit RSA private key

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.

-rw-r--r--. 1 root root 1391 Apr 21 13:29 nginx.crt
-rw-r--r--. 1 root root 1704 Apr 21 13:29 nginx.key

3、Nginx安裝http_ssl_module模塊
Nginx若是未開啓SSL模塊，配置Https時提示錯誤。瀏覽器

nginx: [emerg] the "ssl" parameter requires ngx_http_ssl_module in /usr/local/nginx/conf/nginx.conf:xxx

nginx缺乏http_ssl_module模塊，編譯安裝的時候帶上--with-http_ssl_module配置就好了。安全

本場景是服務器已經安裝過nginx，可是未安裝http_ssl_module。服務器

1.進入到源碼包，如：網絡

cd /app/download/nginx-1.16.7

2.configure：session

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

3.make：

make

4.不須要執行make install，不然就覆蓋安裝了。

5.備份原有的nginx，如：

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx_bak

6.而後將剛剛編譯好的nginx覆蓋掉原有的nginx（nginx須要中止）

cp ./objs/nginx /usr/local/nginx/sbin/

7.查看安裝狀況：(注：若不生效，則重裝nginx)

/usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

4、nginx配置https
貼部分配置信息：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       7777;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            if (!-e $request_filename) {
                rewrite ^(.*)$ /index.html?s=$1 last;
                break;
            }
            root   /usr/local/chip/product/crdp_plus;

先檢驗配置的對不對：

/usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

重啓nginx：

/usr/local/nginx/sbin/./nginx -s reload
