IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:S54ELHiEJBF+g9SUCcaqOjJEhsuOiERtt/25V5g6E1I.
Please contact your system administrator.
Add correct host key in C:\\Users\\admin/.ssh/known_hosts to get rid of this message.

ESC配置nginx：
step1:在阿里云添加了安全组规则，配置80端口

step2: nginx.conf用默认的配置内容（开始以为是server_name需要配置ip地址，其实不用）

配置前端静态页面地址
step3: 查询防火墙状态：firewall-cmd --state

step4:启用nginx:
./nginx -t：验证nginx配置文件是否正确
image.png
./nginx：启动nginx
./nginx -s stop：停止nginx
./nginx -s reload：重启Nginx服务
ps -ef | grep nginx：查看nginx进程

step5：公网ip访问（阿里云有分公ip和私ip，最开始用私ip一直访问不成功，后用公ip访问可以，lol）
