I am currently using let’encrypt with the Tomcat APR without using the Apcahe server or Nginx
I tried to do a certificate renewal test but I can not renew it before 30 days.
I want to set up automatic certificate renewal with Cron.
The question is
-
Issuance of certificate was issued to 80 port and now 80 port is closed. Now I have only 443 ports open. Is it possible to update let’s encrypt to port 443 by closing port 80?
-
Restarting Tomcat via Cron can cause service problems, so Cron can even renew the certificate and the developer must restart Tomcat. If I renew my certificate, will my old certificate be unusable? (Do I have to renew my certificate and restart Tomcat? Can I renew my certificate and restart Tomcat later?)
I am very curious.
