FIPS SSL Configuration

See FIPS SSL Configuration.

Customizing SSL Configuration

During Installation

During installation the installer will use the default SSL configuration. Under certain circumstances (e.g. in FIPS mode) the default SSL configuration may not work. To customize the SSL configuration during installation use the Two-Step Installation:

  • Prepare a normal deployment configuration.
  • Add pki_skip_configuration=True to the configuration and run pkispawn.
  • Customize the SSL parameters as needed in /var/lib/pki/pki-tomcat/conf/server.xml
  • Replace pki_skip_configuration=True with pki_skip_installation=True and run pkispawn again.

After Installation

After installation the SSL settings can be customized directly in /var/lib/pki/pki-tomcat/conf/server.xml.
