![certmonger 为 nginx 保存链式证书](https://linux22.com/image/697213/certmonger%20%E4%B8%BA%20nginx%20%E4%BF%9D%E5%AD%98%E9%93%BE%E5%BC%8F%E8%AF%81%E4%B9%A6.png)
我们使用 certmonger 为后端系统颁发证书,这对于 apache 来说很好,但对于 nginx,我必须指定链式证书。
getcert request -f /etc/pki/tls/certs/$(hostname).crt -k /etc/pki/tls/private/$(hostname).key -r -F /etc/pki/tls/certs/intermediate.crt
选项 1) 我可以让 certmonger 以两种格式保存证书吗?(首选)
选择 2)我可以告诉 nginx 为我链接证书吗?(类似于 apache 的做法)
我想避免编写脚本,但如果必须的话,那也没关系。
例子:
/etc/pki/tls/certs/$(主机名).crt

一如既往,答案是操作系统。

脚本就可以了,只需要添加之前/之后的命令。
