悲催了

1.删除Let’s encrypt安全证书的域名
（1）使用命令
查看已安装证书：certbot certificates
删除已安装证书：certbot delete --cert-name example.com
（2）删除文件，不要这样不要这样，删除原有的要备份！！！
rm -rf /etc/letsencrypt/live/ www.example.com/
rm -rf /etc/letsencrypt/archive/ www.example.com/
rm -y /etc/letsencrypt/renewal/ www.example.com.conf
2.继续报错
There were too many requests of a given type :: Error creating new order :: too many certificates already issued for exact set of domains: .xxx.com,yiyfc.com : see https://letsencrypt.org/docs/rate-limits/
服务器已经停了4个小时了，客服部明天应该感谢我，ε=(´ο｀ )))唉！！！
