一、Http与Https的区别
HTTP:是互联网上应用最为广泛的一种网络协议,是一个客户端和服务器端请求和应答的标准(TCP),用于从WWW服务器传输超文本到本地浏览器的传输协议,它可以使浏览器更加高效,使网络传输减少。
HTTPS:是以安全为目标的HTTP通道,简单讲是HTTP的安全版,即HTTP下加入SSL层,HTTPS的安全基础是SSL,因此加密的详细内容就需要SSL。HTTPS协议的主要作用可以分为两种:一种是建立一个信息安全通道,来保证数据传输的安全;另一种就是确认网站的真实性。
HTTPS和HTTP的区别主要如下:
1、https协议需要到ca申请证书,一般免费证书较少,因而需要一定费用。
2、http是超文本传输协议,信息是明文传输,https则是具有安全性的ssl加密传输协议。
3、http和https使用的是完全不同的连接方式,用的端口也不一样,前者是80,后者是443。
4、http的连接很简单,是无状态的;HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议,比http协议安全。
二、使用openssl生成证书
openssl是目前最流行的SSL密码库工具,其提供了一个通用、健壮、功能完备的工具套件,用以支持SSL/TLS协议的实现。
比如生成到:/usr/local/ssl
openssl req -x509 -nodes -days 36500 -newkey rsa:2048 -keyout /usr/local/ssl/nginx.key -out /usr/local/ssl/nginx.crt
生成过程:
# 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.

三、Nginx安装http_ssl_module模块
Nginx如果未开启SSL模块,配置Https时提示错误。
nginx: [emerg] the "ssl" parameter requires ngx_http_ssl_module in /usr/local/nginx/conf/nginx.conf:xxx
nginx缺少http_ssl_module模块,编译安装的时候带上--with-http_ssl_module配置就行了。
本场景是服务器已经安装过nginx,但是未安装http_ssl_module。
1.进入到源码包,如:
cd /app/download/nginx-1.12.2
2.configure:
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
3.make:
make
4.不需要执行make install,否则就覆盖安装了。
5.备份原有的nginx,如:
cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx_bak
6.然后将刚刚编译好的nginx覆盖掉原有的nginx(nginx需要停止)
cp ./objs/nginx /usr/local/nginx/sbin/
7.查看安装情况:
/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
四、nginx配置https
贴部分配置信息:
server {
listen 80;
server_name www.yourdomain.com;
rewrite ^(.*) https://$server_name$1 permanent; #http 跳转 https
}
server {
listen 443 ssl;
server_name www.yourdomain.com;
ssl_certificate /usr/local/ssl/nginx.key;
ssl_certificate_key /usr/local/ssl/nginx.crt;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
#禁止在header中出现服务器版本,防止黑客利用版本漏洞攻击
server_tokens off;
#如果是全站 HTTPS 并且不考虑 HTTP 的话,可以加入 HSTS 告诉你的浏览器本网站全站加密,并且强制用 HTTPS 访问
fastcgi_param HTTPS on;
fastcgi_param HTTP_SCHEME https;
access_log /usr/local/nginx/logs/httpsaccess.log;
}
先检验配置的对不对:
/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
重启nginx:
/usr/local/nginx/sbin/nginx -s reload
