Nginx

步骤
1.首先你需要有一个域名，把域名解析出来，申请一个当前域名的ssl证书
2.安装nginx，网站一般默认端口是80，https端口默认端口是443，所以在服务器打开443端口
3.使用ssh连接服务器，修改nginx（nginx.conf）配置文件
4.修改完成之后重启nginx就可以了

我的配置代码块中#注释的地方需更改为你自己的

# http -----> Https 如果使用的http协议访问，重定向到https访问
server {
    listen         80;
    server_name    www.haore.top; # 域名
    add_header Strict-Transport-Security max-age=15768000;
    return 301 https://$server_name$request_uri;
}
# Https 的配置
server {
    listen 443 ssl; # 老版本是ssl on;较新的为listen 443 ssl;
    server_name www.haore.top; # 域名
    
    keepalive_timeout 10m;
    ssl_certificate      /home/jar/www.pem; # 申请的证书
    ssl_certificate_key  /home/jar/www.key; # 申请的证书秘钥
    ssl_session_timeout 24h;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    location / {
            proxy_pass http://127.0.0.1:8288; # 反向代理到本机的8288端口，这个就是你springboot项目端口地址，8288端口的那个服务器不需要任何关于https的配置。
            proxy_redirect off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Forwarded-Port $server_port;
        }
}

附赠一个反向代理 http 的配置文件

#后台代码&数据库
 server {
      listen 80;
      server_name  zcxcs.haore.top; #域名
   		location / {   
  			add_header 'Access-Control-Allow-Origin' $http_origin;
  			add_header 'Access-Control-Allow-Credentials' 'true';
  			add_header 'Access-Control-Allow-Methods' '*';
 			add_header 'Access-Control-Allow-Headers' 'DNT,web-token,app-token,Authorization,Accept,Origin,Keep-Alive,User-Agent,X-Mx-ReqToken,X-Data-Type,U-TOKEN,E-TOKEN,X-Auth-Token,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
  			add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
  			if ($request_method = 'OPTIONS') {
				add_header 'Access-Control-Allow-Origin' $http_origin;
   				add_header 'Access-Control-Allow-Credentials' 'true';
   				add_header 'Access-Control-Allow-Methods' 'GET,POST,DELETE,PUT,OPTIONS';
   				add_header 'Access-Control-Allow-Headers' 'DNT,web-token,app-token,Authorization,Accept,Origin,Keep-Alive,User-Agent,X-Mx-ReqToken,X-Data-Type,U-TOKEN,E-TOKEN,X-Auth-Token,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
   				add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';

   				add_header 'Access-Control-Max-Age' 1728000;
   				add_header 'Content-Type' 'text/plain; charset=utf-8';
  				add_header 'Content-Length' 0;
   				return 204;
  			}
  
  		proxy_pass http://localhost:8288; #项目地址
 		proxy_set_header Host ${Host};
  		proxy_set_header X-Real-IP $remote_addr;
  		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  		proxy_set_header X-Forwarded-Proto $scheme;
 	 	proxy_connect_timeout 5;
   		}
  }
