Create an SSL certificate for Apache
OpenSSL is required to create an SSL certificate. A certificate request can then be sent to a certificate authority (CA) to get it signed into a certificate, or if you have your own certificate authority, you may sign it yourself, or you can use a self-signed certificate (because you just want a test certificate or because you are setting up your own CA).
NOTE: OpenSSL will typically already be installed on Linux and Mac OS X. If not installed, install it manually using your operating system’s package manager.
Follow the steps below:
Generate a new private key:
$ sudo openssl genrsa -out /opt/bitnami/apache2/conf/server.key 2048
Create a certificate:
$ sudo openssl req -new -key /opt/bitnami/apache2/conf/server.key -out /opt/bitnami/apache2/conf/cert.csr
IMPORTANT: Enter the server domain name when the above command asks for the “Common Name”.
Send cert.csr to the certificate authority. When the certificate authority completes their checks (and probably received payment from you), they will hand over your new certificate to you.
Until the certificate is received, create a temporary self-signed certificate:
$ sudo openssl x509 -in /opt/bitnami/apache2/conf/cert.csr -out /opt/bitnami/apache2/conf/server.crt -req -signkey /opt/bitnami/apache2/conf/server.key -days 365
Back up your private key in a safe location after generating a password-protected version as follows:
$ sudo openssl rsa -des3 -in /opt/bitnami/apache2/conf/server.key -out privkey.pem
Note that if you use this encrypted key in the Apache configuration file, it will be necessary to enter the password manually every time Apache starts. Regenerate the key without password protection from this file as follows:
$ sudo openssl rsa -in privkey.pem -out /opt/bitnami/apache2/conf/server.key
