ndo2db will not start after server migration

[mxthunder]

We have recently migrated 2 Nagios servers from our datacenter in Lorain Ohio to IBM datacenter in the cloud.
A bit level copy of the servers was performed, however when we attempted to bring up the new "target servers" ndo2db would not start.
All other nagios services were able to start, and UI was accessible from web.

Try doing a restart and remove the lock files. Run through the following commands.

Code: Select all

systemctl stop nagios
systemctl stop ndo2db
pkill -9 -u nagios
rm -f /usr/local/nagios/var/rw/nagios.cmd
rm -f /usr/local/nagios/var/nagios.lock
rm -f /usr/local/nagios/var/ndo.sock
rm -f /usr/local/nagios/var/ndo2db.lock
rm -f /usr/local/nagiosxi/var/reconfigure_nagios.lock
systemctl start ndo2db

Thank you, removing the .sock file fixed the issue.
