Installing an Apache Server Certificate
After installation, you might want to create a new Apache certificate.
By default, Accelerator generates a temporary self-signed certificate during installation. This certificate is used whenever a browser makes an HTTPS connection to the Apache server. During Accelerator installation, Apache is configured to look for a private key file named
$HOSTNAME.key and a certificate named
$HOSTNAME.crt. These files are in
$DATADIR is the directory where Accelerator data files were installed. On Windows, these files are in
Because the certificate is self-signed, browsers complain that it is an untrusted certificate. Most organizations will want to generate a new certificate signed by a recognized certificate authority (CA) to avoid the browser warnings. The following list summarizes the process:
Generate a new certificate and private key
Send the request to the CA
Install the signed certificate
openssl.cnfinto a temporary directory.
Generate a new private key and certificate.
Enter the appropriate information for your organization when prompted.
The most important field is the Common Name, which is the fully qualified name of the host running the Apache server where you want the certificate. This name must match the host portion of the URL used to connect to the Cluster Manager.

|This is the email address the user would contact if there are issues concerning the certificate.|
Please enter the following 'extra' attributes to be sent with your certificate request.A challenge password :
This information generates a new private key in
privkey.pem and a signing request in
If you want to use the private key without having to enter a challenge password each time the server starts, issue the following command to strip out the password:
$ openssl rsa -in privkey.pem -out $HOSTNAME.keyEnter pass phrase for privkey.pem:writing RSA key
This creates a PEM encoded private key file named
$HOSTNAME.key without the password.
$HOSTNAME.csr file generated in the previous section is a request for a certificate authority to sign the certificate. When you send this file to the CA, the CA verifies the information inside and sends you a signed certificate in response. The signed certificate includes the original certificate and the signature of the CA. Name the signed certificate '
Copy the two files,
Restart the Apache server.
$HOSTNAME.key file is readable only by the user running the Apache server process.
Delete the contents of the temporary directory you created because this directory contains the cryptographic information used to generate the key.
