Nagios Support Forum

Hello Team,

I am unable to start or stop the nagios services. I get the below error messages.

[sadmin@nagiosxi ~]$ service nagios stop
Stopping nagios: No lock file found in /var/run/nagios.lock
[sadmin@nagiosxi ~]$

Can you please let me know how do I resolve this?

Hello, @smapple. What version of XI are you on? Please run the following commands and show me the output:

cat /etc/rc.d/init.d/nagios | grep NagiosRunFile=
cat /usr/local/nagiosxi/scripts/nom_restore_nagioscore_checkpoint.sh | grep lockfile=

@smapple , Is httpd running? service httpd status
Please upload /var/log/httpd/error_log or if you're using ssl /var/log/httpd/ssl_error_log

(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down

Http error

@smapple, Do you have some other application that is already listening on the port 80? Can you show me the output of this command:

sudo netstat -tulpn| grep :80

Then kill all httpd processes and start it again:

killall -9 httpd
service httpd start

Thank you! The issue is resolved!
