通过 ttyd 实现网页 SSH，并且使用 cloudflare 打开代理，使支持 ipv4 和 ipv6，随时随地访问!

1. 安装 ttyd

   wget wget https://github.com/tsl0922/ttyd/releases/download/1.7.4/ttyd.x86_64 -O /usr/sbin/ttyd

   chmod +x /usr/sbin/ttyd

2. 新建服务

   systemctl edit --force --full ttyd.service

3. 粘贴以下内容，ctrl+x 点 y 回车保存退出

   [Unit]
   Description=ttyd
   After=network.target

   [Service]
   ExecStart=/usr/sbin/ttyd -W --ipv6 -c demo:196000.xyz -p 2086 login

   [Install]
   WantedBy=multi-user.target

4. 设置自启

   systemctl enable ttyd
   systemctl start ttyd
   systemctl status ttyd

5. 反向代理

   server {

   listen 80;
   listen [::]:80;
   server_name  blog.196000.xyz;
   location ~ ^/ttyd(.*)$ {  
       proxy_http_version 1.1;  
       proxy_set_header Host $host;  
       proxy_set_header X-Forwarded-Proto $scheme;  
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  
       proxy_set_header Upgrade $http_upgrade;  
       proxy_set_header Connection "upgrade";  
       proxy_pass http://127.0.0.1:27681/$1;  
   }

   }

6. 域名访问
