I have a web server on which Apache 2.4.9 and Openssl 1.0.1g are installed and I have a certificate installed on the server. I would like to upgrade Apache and the Openssl version to Apache 2.4.16 and Openssl to 1.0.2d. My concern is that the certificate will stop working if I update and try to install the certificate later.
Can I perform this update? Is there a file (other than certificates, private keys and httpd.conf) that I need to copy before updating?
There is no reason for certificate to crash, it is independent of webserver. I can’t say in my head everything you need to copy, but I believe it to be the certificate itself, your private key, and the root certificate chain (in your httpd.conf, it must be referenced by
SSLCertificateChainFile
andSSLCACertificateFile
), can be downloaded from the CA that signed your certificate.– mgibsonbr
