I was running icinga2 api setup (page 23) and remember the first time it didn’t work, so i just ran it again and it finished like this:
information/cli: Generating new CA.
critical/cli: CA files '/var/lib/icinga2/ca//ca.crt' and '/var/lib/icinga2/ca//ca.key' already exist.
warning/cli: Found CA, skipping and using the existing one.
information/cli: Private key file '/var/lib/icinga2/certs//filename.key' already exists, not generating new certificate.
information/cli: API user config file '/etc/icinga2/conf.d/api-users.conf' already exists, not creating config file.
information/cli: Enabling the 'api' feature.
warning/cli: Feature 'api' already enabled.
information/cli: Updating 'NodeName' constant in '/etc/icinga2/constants.conf'.
information/cli: Backup file '/etc/icinga2/constants.conf.orig' already exists. Skipping backup.
information/cli: Updating 'ZoneName' constant in '/etc/icinga2/constants.conf'.
information/cli: Backup file '/etc/icinga2/constants.conf.orig' already exists. Skipping backup.
Done.
Now restart your Icinga 2 daemon to finish the installation!
Sadly I can’t recall the output of the first (failed) setup. Can i roll back the setup somehow and simply try again?
