can I just restart mysqld or do I need to restart in a certain order? service mysqld restart

Will this work or should I just reboot?

service nagios stop
service npcd stop
service ndo2db stop
service mysqld stop
service postgresql stop
service httpd stop
service crond stop
service crond start
service httpd start
service postgresql start
service mysqld start
service ndo2db start
service npcd start
service nagios start

Hello, @ace. Please run the repair DB script as root first and make sure that your server is not running out of disk space "df -h":

/usr/local/nagiosxi/scripts/repair_databases.sh

Next, run these commands if you are on CentOS/RHEL 6.X:

service crond stop
service npcd stop
service nagios stop
service ndo2db stop
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
service mysqld restart
service ndo2db start
service nagios start
service npcd start
service crond start

Run these commands if you are on CentOS/RHEL 7.X:

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

the database repair fixed the issue and freed up space on /tmp
I didn't restart any of the services/

Thanks!

@ace, No problem. I will be closing this thread as resolved but feel free to open a new one if something else comes up.
