三个月时间到了,证书需要续期,在网上找了好久都是通过脚本自动执行的方式进行续期的,在这里都不适用,通过参考各种资料和摸索,找到以下方法供参考:文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/31169.html

sudo certbot certonly --renew-by-default -d YOURDOMAIN --manual --preferred-challenges dns文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/31169.html

certonly 只申请证书
--renew-by-default 通过默认配置更新证书
-d YOURDOMAIN 需要更新证书的域名
--manual 交互方式执行
--preferred-challenges dns 通过DNS TXT记录的方式进行认证文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/31169.html

执行以上命令后返回如下结果:文章源自菜鸟学院-https://www.cainiaoxueyuan.com/wg/31169.html
