How to install a new ssl on Ubuntu to replace existing one?

Hi, I already have installed a SSL certificate last year on a Ubuntu server. Now the renewal of the certificate issuing is taking forever, so I am thinking to install a temporary Let’s Encrypt SSL certificate for the time being.

Even though there is already an SSL certificate installed manually in the virtual host conf,…

<VirtualHost *:443>
    ServerName mydomain.sg
    ServerAdmin admin@mydomain.sg
    DocumentRoot /var/www/html
    SSLEngine on
    SSLCertificateFile /home/keys/mydomain.sg.crt
    SSLCertificateKeyFile /home/keys/mydomain.sg.key
    SSLCertificateChainFile /home/keys/intermediate.crt

Can I still follow this tutorial?https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04

Hello, @chris4ever

In order to renew the SSL you can replace the files listed in the virtual host:

SSLCertificateFile /home/keys/mydomain.sg.crt
SSLCertificateKeyFile /home/keys/mydomain.sg.key
SSLCertificateChainFile /home/keys/intermediate.crt

You can also install a Let’s Encrypt for the domain name by following the tutorial, this is totally up to you.
