I have tried to deinstall and reinstall the ipa server but the
installation is now failing.

The ipa-server-install is failing with the following:

 [37/38]: tuning directory server
 [38/38]: configuring directory to start on boot
Done configuring directory server (dirsrv).
Configuring certificate server (pki-tomcatd): Estimated time 3 minutes

'/usr/sbin/pkispawn -s CA -f /tmp/tmpLb1CmI' returned non-zero exit

Configuration of CA failed

This happens each time I try to uninstall and reinstall the ipa server
on RHEL V7.

Looking at the latest log in /var/log/pki, I see this at the end of
the log:

I am no python expert by any means and I'm not sure what this is
telling us so any help
would be greatly appreciated.

This issue is known -- when CA install fails, we rollback but since CA
isn't installed, we miss rolling it back. There is a ticket for
eventually fixing this issue.

Which ticket is this? The rollback was actually disabled to allow troubleshooting the failed installation:

Following sequence should clean up all the bits:

pkidestroy -s CA -i pki-tomcat
rm -rf /var/log/pki/pki-tomcat
rm -rf /etc/sysconfig/pki-tomcat
rm -rf /etc/sysconfig/pki/tomcat/pki-tomcat
rm -rf /var/lib/pki/pki-tomcat
rm -rf /etc/pki/pki-tomcat

It's not official, but we call this step pki-nuke.

It also helps to reboot between multiple reinstalls on a single machine.

Rather than rolling back the installation automatically (and delete all files needed to troubleshoot the problem), it would be better to provide an option to the uninstall command to forcibly remove all installed files regardless whether the installation was successful or not, just like the pki-nuke above.
