推荐答案

我创建了一个bash脚本来解决认证PEM文件续订有效期的问题

I create a bash script to solve question of renew expiry date of a certification PEM file

#!/bin/bash

# FIXME we need shttp.pem are on same folder like execution path of script
# Extract a certificate sign request form certification file (PEM)
openssl x509 -x509toreq -in shttpd.pem -out shttpd.csr -signkey shttpd.pem
# Extract private key from certification file (PEM)
openssl rsa -in shttpd.pem -out shttpd.key
# Create new certification for ten years
openssl x509 -req -days 3650 -in shttpd.csr -out shttpd.crt.new -signkey shttpd.key 
#Concatenate new certificate and old private key on a renewed pem file
cat shttpd.crt.new shttpd.key > shttpd.pem.new
