一、https简介

https 密文

1、安全访问

数据的安全性，加密/解密
数据的完整性
身份的真实性

2、数据的安全性

发送方加密数据，接收方解密数据

对称加密算法
加密、解密时使用的密钥是一样的
典型算法: DES、3DES、AES
非对称加密算法
密钥对，公钥、私钥
公钥加密、私钥解密
典型算法: RSA、DSA
使用原则
使用对称算法加密真实的数据，使用非对称算法加密对称算法中的密钥

3、数据的完整性

借助哈希算法保证数据的完整性
哈希算法: MD5、SHA

[root@node01 ~]# md5sum /etc/fstab 
e48a442f1af72ac73d69ba0b12de254b  /etc/fstab

[root@node01 ~]# sha224sum /etc/passwd
6b427e3f351f343325baa53ef9a04f14ff13172f50ee9c2fd32fbe65  /etc/passwd

3、身份的真实性

私钥签名，公钥验证签名
在这里插入图片描述 - 实际应用：
密钥、证书

证书的来源
互联网上发布业务，向CA申请证书
私有CA

二、配置https网站

1、环境规划

manage.linux.com /web/manage
192.168.140.10 nginx服务器
192.168.140.11 私有CA

2、部署私有CA

创建两个数据库文件

[root@ca ~]# touch /etc/pki/CA/index.txt

[root@ca ~]# echo 01 > /etc/pki/CA/serial

[root@ca ~]# cat /etc/pki/CA/serial
01

创建密钥对

[root@ca ~]# openssl genrsa -out /etc/pki/CA/private/cakey.pem 1024 
Generating RSA private key, 1024 bit long modulus
...++++++
..............++++++
e is 65537 (0x10001)

创建自签证书

[root@ca ~]# openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 3650
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.
-----
Country Name (2 letter code) [XX]:cn
State or Province Name (full name) []:bj
Locality Name (eg, city) [Default City]:bj
Organization Name (eg, company) [Default Company Ltd]:easthome
Organizational Unit Name (eg, section) []:easthome
Common Name (eg, your name or your server's hostname) []:ca.linux.com
Email Address []:

3、部署https的虚拟主机

创建网站的密钥

[root@node01 ~]# mkdir /usr/local/nginx/ssl
[root@node01 ~]# cd /usr/local/nginx/ssl
[root@node01 ssl]# openssl genrsa -out manage.key 1024 
Generating RSA private key, 1024 bit long modulus
....++++++
.......................++++++
e is 65537 (0x10001)

[root@node01 ssl]# ls
manage.key

创建证书申请

[root@node01 ssl]# openssl req -new -key manage.key -out manage.csr
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.
-----
Country Name (2 letter code) [XX]:cn
State or Province Name (full name) []:bj
Locality Name (eg, city) [Default City]:bj
Organization Name (eg, company) [Default Company Ltd]:easthome
Organizational Unit Name (eg, section) []:easthome
Common Name (eg, your name or your server's hostname) []:manage.linux.com
Email Address []:bj@qq.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

将证书申请发送到CA审核

[root@node01 ssl]# scp manage.csr root@192.168.140.11:/opt/
manage.csr                                                            100%  688   744.6KB/s   00:00    
[root@node01 ssl]#

CA签发证书，将证书发送回网站服务器

[root@ca ~]# openssl ca -in /opt/manage.csr -out /etc/pki/CA/certs/manage.crt -days 3650 
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature

[root@node01 ~]# mkdir -p /web/manage
[root@node01 ~]# vim /web/manage/index.html
[root@node01 ~]# cat /web/manage/index.html
<h1> web manage </h1>

确认nginx安装了ssl模块

[root@node01 ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.26.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module

配置虚拟主机

[root@node01 ~]# cat /usr/local/nginx/conf.d/manage.conf
server {
    listen       443 ssl;
    server_name  manage.linux.com;

    error_log /usr/local/nginx/logs/manage_error.log error;
    access_log /usr/local/nginx/logs/manage_access.log main;

    ssl_certificate      /usr/local/nginx/ssl/manage.crt;
    ssl_certificate_key  /usr/local/nginx/ssl/manage.key;

    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;

    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers  on;

    location / {
        root   /web/manage;
        index  index.html index.htm;
    }
}

[root@node01 ~]# vim /usr/local/nginx/conf/nginx.conf

    include       /usr/local/nginx/conf.d/manage.conf;

重新加载nginx，测试访问

[root@node01 ~]# /usr/local/nginx/sbin/nginx -s reload

[root@node01 ~]# netstat -tunlp | grep nginx
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      1029/nginx: master  
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1029/nginx: master

在这里插入图片描述

三、URL重写

1、语法

rewrite   旧uri地址	新uri地址;

注意事项: 
1、旧地址不包含请求中的参数
2、旧地址支持正则表达式
3、建议新地址写完整的URL地址，避免循环替换

需求1：

	rewrite ^/audio  http://blog.linux.com/mp3;

	rewrite ^/audio/(.*)  http://blog.linux.com/mp3/$1;

需求2: 网站换名

	rewrite ^/   https://www.jd.com;

需求3: https自动跳转

       if ($host = manage.linux.com) {
            rewrite ^/   https://manage.linux.com;
       }

$host：nginx内部变量，用于匹配网站的主机名

四、location的写法

1、语法

 	location [ = | ~ | ~* | ^~ ] uri { ... }

2、location = uri {}

精确匹配

location = /test { }			http://x.y.z/test

location = / { }					http://x.y.z/

   // 定义错误页面
   error_page 404 /404.html;
   location = /404.html {
      root /web/blog;
   }

3、location ~ uri { }

以正则表达式的方式匹配请求，区分大小写

location ~ /test { }
http://x.y.z/test/b
http://x.y.z/a/b/test
http://x.y.z/admin/test/person

// 匹配所有图片的请求 
location ~ \.(jpg|jpeg|gif|png)$ { }

4、location ~* uri { }

以正则表达式的方式匹配请求，不区分大小写

location ~* \.php$ { }

http://x.y.z/test/index.php
http://x.y.z/test/admin.PHP

5、location ^~ uri { }

不以正则表达式的方式匹配请求

location ^~ /test {}
http://x.y.z./test/ab/c
http://x.y.z/test/logo/admin

5、location的优先级

同一个网站中存在多个location时，一个请求可能会被多个location同时匹配，按优先级处理

从高到低 
=		^~	~		~* 	location /

五、nginx处理php页面

nginx默认只能处理静态资源，服务器上运行PHP网站，还得需要php软件的支持，同时需要配置nginx通过fastCGI机制能够成功调用php

1、安装php-fpm

[root@node01 ~]# yum install -y php php-fpm 

[root@node01 ~]# systemctl enable --now php-fpm

[root@node01 ~]# netstat -tunlp | grep php
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      2576/php-fpm: maste 
[root@node01 ~]# 
[root@node01 ~]# ps -elf | grep php  
4 S root       2576      1  0  80   0 - 58155 ep_pol 10:35 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
5 S apache     2577   2576  0  80   0 - 58242 inet_c 10:35 ?        00:00:00 php-fpm: pool www
5 S apache     2578   2576  0  80   0 - 58155 inet_c 10:35 ?        00:00:00 php-fpm: pool www
5 S apache     2579   2576  0  80   0 - 58155 inet_c 10:35 ?        00:00:00 php-fpm: pool www
5 S apache     2580   2576  0  80   0 - 58242 inet_c 10:35 ?        00:00:00 php-fpm: pool www
5 S apache     2581   2576  0  80   0 - 58155 inet_c 10:35 ?        00:00:00 php-fpm: pool www

2、配置nginx调用php

   location ~ \.php$ {
      root           /web/blog;
      fastcgi_pass   127.0.0.1:9000;				// 调用php,指定php的IP和端口
      fastcgi_index  index.php;
      fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
      include        fastcgi_params;
  }

3、测试访问php页面

<h1> AAAAAAAAAAAAAAA </h1>
<h2> BBBBBBBBBBBBBBB </h2>

<?php
  phpinfo();
  echo "<h1>Hello PHP, wmh@@@@@World!</h1>";
?>
