手动部署letsencrypt的ssl证书[0]

Posted on 2023年11月14日 by

本篇也可以称为泛域名证书的申请

对于非80端口的证书的获取,一直是个问题,尤其是对于默写应用场景下,自签名证书非常不安全。因此需要手动部署ssl证书,通过域名TXT验证所有权,好在可以用通配符进行全域名的证书的申请,避免一个个证书的到期问题。

  • 部署过程

1)域名上增加TXT记录

2)部署自动化工具

yum install certbot -y
certbot certonly --manual --preferred-challenge dns -d  "*.so.com"

以上存在一个坑,在没有通过TXT验证前,不能回车验证,否者重新运行会重新生成验证字符。

3)另外开启一个ssh,检查TXT验证

yum install bind-utils -y
dig _acme-challenge.so.com txt

验证成功后,再回车即可。

测试通过。

缺点:三个月手动定期更新证书,过程重复即可。
