Generating Self-Signed Certificates and Certificate Signing Requests

When you generate a self-signed certificate, a new self-signed certificate in PEM format and a Certificate Signing Request (CSR) file are created in the opt/certs/ directory. When generating a self-signed certificate, clicking enter will select the default option. For example, if you do not specify a domain name, the shell admin by default chooses the domain name of the appliance that is configured.

You can generate a self-signed certificate and a CSR using the Generate Self-Signed Certificate and Certificate Signing Request option.
    Step 1   From the Cisco UCS Director Shell menu, choose the Generate Self-Signed Certificate and Certificate Signing Request and press Enter.
    The following information is displayed:

    Importing Certification Authority or Self-Signed Certificates

    You can either import the generated self-signed certificate or import a certificate generated by another system or third party by copying .pem and .key (private key) files to the /opt/certs/ directory. The shell admin will automatically discover the .pem and .key files for the given domain in the /opt/certs/ directory. The .pem file provided is exported into PKCS12 format, and then converted to JKS format. The JKS file can be imported into Tomcat.

    You can import a CA signed certificate or self-signed certificate using the Importing CA/Self-Signed Certificate option.

      Step 1   From the Cisco UCS Director Shell menu, choose the Importing CA/Self-Signed Certificate option and press Enter.

      The following information is displayed: 

      Domain Name [localdom]:
      Step 2   Enter the domain name and press Enter.

      By default the shell menu selects the domain name of the local appliance that is configured.

      The following information is displayed: 

      Enter CA/self-signed certificate [/opt/certs/localdom.pem]:
      Step 3   Enter the path to the CA signed certificate or self-signed certificate, and press Enter.

      The following information is displayed: 

      Enter private key [/opt/certs/localdom.key]:
      Step 4   Enter the path to the private key and press Enter.
