Auto renewing the Lets encrypt certificate for redhat/ubuntu (tomcat) instance



Thanks for reading this. Let me know if any one knows how to update the auto renewal of Lets encrypt certificate. Now my domain has installed with the certificate. I want it to be auto renewal after every 3 months is there any method to do it.

My domain is:

I ran this command: installed

It produced this output: Now it is with ssl

My web server is (include version): Tomcat 8.5.13

The operating system my web server runs on is (include version): ubuntu

My hosting provider, if applicable, is: AWS

I can login to a root shell on my machine (yes or no, or I don’t know): Yes, I can login to the root

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):



How do you obtained the certificate?
Did you use any of the client listed in this?

Thank you


I have used the cerbot client.

by using the below commands
sudo keytool -genkey -noprompt -alias tomcat -keyalg RSA -keystore ~home/conf/.keystore -keysize 2048 -dname “CN=domainname, OU=Dlabs, O=IOT, L=Blr, S=Kar, C=91” -keypass “password” -storepass “password”

keytool -certreq -alias tomcat -file request.csr -keystore ~home/conf/.keystore -storepass “password”

certbot certonly --standalone -d domainname --csr request.csr

sudo keytool -import -trustcacerts -alias tomcat -file 0001_chain.pem -keystore ~home/conf/.keystore -storepass “password”
