Hi @Pselvin,

Job for mariadb.service failed because the control process exited with error code

It looks like mariadb is unable to start. Please post the database log file for us to review.

Code: Select all

tail /var/log/mariadb/mariadb.log

Next, try re-starting the Nagios stack and let us know if your able to login into the GUI.

Code: Select all

systemctl stop crond
systemctl stop npcd
systemctl stop nagios
systemctl stop ndo2db
pkill -9 -u nagios
for i in $(ipcs -q | grep nagios |awk '{print $2}'); do ipcrm -q $i; done
rm -rf /usr/local/nagiosxi/var/dbmaint.lock
rm -rf /usr/local/nagiosxi/var/event_handler.lock
rm -rf /usr/local/nagiosxi/scripts/reconfigure_nagios.lock
systemctl restart mariadb
systemctl start ndo2db
systemctl start nagios
systemctl start npcd
systemctl start crond
