集群架构-https

1.什么是Https
2.为什么要使用Https
3.模拟不使用Https的劫持和篡改?
4.Https通讯是如何确定双方的身份？
5.Https证书类型、购买指南、注意事项?

Https不支持续费,证书到期需重新申请新并进行替换。
Https不支持三级域名解析，如 test.m.oldboy.com。
Https显示绿色，说明整个网站的url都是https的，并且都是安全的。
Https显示黄色，说明网站代码中有部分URL地址是http不安全协议的。
Https显示红色，要么证书是假的，要么证书已经过期。


6.如何实现单台Https、又如何实现集群Https?

#创建存放ssl证书的路径
[root@Nginx ~]# mkdir -p /etc/nginx/ssl_key
[root@Nginx ~]# cd /etc/nginx/ssl_key

实验：

1.生成证书 (密码1234)
[root@Nginx ~]# openssl genrsa -idea -out server.key 2048

2.生成自签证书，同时去掉私钥的密码
openssl req -days 36500 -x509 \
-sha256 -nodes -newkey rsa:2048 -keyout server.key -out server.crt

配置nginx

[root@web01 conf.d]# cat s.oldux.com.conf 
server {
    listen 443 ssl;
    server_name s.oldxu.com;
    root /code;
    ssl_certificate ssl_key/server.crt;
    ssl_certificate_key ssl_key/server.key;

    location / {
        index index.html;
    }
}
server {
    listen 80;
    server_name s.oldxu.com;
    return 302 https://$http_host$request_uri;    
}

云主机配置

yang.conf 
server {
    listen 443 ssl;
    server_name wq.yanghuanhuan.top;
    root /code/wordpress;
    ssl_certificate ssl_key/2861173_wq.yanghuanhuan.top.pem;
    ssl_certificate_key ssl_key/2861173_wq.yanghuanhuan.top.key;
    client_max_body_size 100m;

    location / {
        index index.php;
    }
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

}

server {
        listen 80;
        server_name wq.yanghuanhuan.top;
        return 302 https://$http_host$request_uri;
}

7.如何将Https集成集群架构实现全站Https?

流程：

1.先配置好后端的web节点
2.在负载均衡上申请证书(如果之前申请过也可以推送) <----
3.配置nginx负载均衡--->http协议
4.配置域名劫持
5.配置nginx负载均衡--->转为https协议

配置

[root@lb01 conf.d]# cat proxy_s.oldxu.com.conf 
upstream webs {
    server 172.16.1.7:80;
    server 172.16.1.8:80;
}

server {
    listen 443 ssl;
    ssl_certificate ssl_key/server.crt;
    ssl_certificate_key ssl_key/server.key;

    server_name s.oldxu.com;
    location / {
        proxy_pass http://webs;
        include proxy_params;
    }
}

server {
    listen 80;
    server_name s.oldxu.com;
    return 302 https://$http_host$request_uri;

.需求: 部分URL走https,部分不走https?

 https
 
[root@lb01 conf.d]# cat proxy_s.oldxu.com.conf 
upstream webs {
    server 172.16.1.7:80;
    server 172.16.1.8:80;
