how to renew ssl certificates?

Posted July 27, 2014 11.2k views

I have a ssl certificate on a domain. Now, I need to renew the security keys.
My server is apache. I will replace the certificates, but now does not want to restart apache.

The error:

~# sudo service apache2 restart
 * Restarting web server htcacheclean                                                                                                                                                                                             ...not running

The Apache error log may have more information.

Have you already renewed your SSL certificates? It looks like the private key was overwritten so now the certificate does not match it and Apache won’t start as a result.

If you have generated a new CSR, the private key was most likely replaced as well, so the only option you have is to renew the SSL certificate as soon as possible.

    Hy @Kamal, thanks.

    I already have one .csr, I used it on certificate disabled.
    will generate a new one .crt through this .csr and try again.

    Can you tell me if it is just change files (crt) and reset the apache?

    Yes, you just need to change the crt. It’s better to generate a new CSR and Key to make sure they match.

    Have you recently modified any of Apache’s config files? Try creating the directory:

    sudo mkdir -p /var/cache/apache2/mod_disk_cache
sudo chown -R www-data /var/cache/apache2/mod_disk_cache
