My new offline install of nagios xi has this error "stderr: sudo: sorry, you must have a tty to run sudo" and it wont start the httpd, crond, mysqld or ndo2db services, can someone please offer any suggestions as to how I might fix this so my services start? I attached the nagios profile. Any advice would be very much appreciated.

Can you show the output of the following

Code: Select all

grep NAGIOS /etc/sudoers
grep requiretty /etc/sudoers|grep nagios

Thanks Scott

I didnt get any result for thase commands however i did find requiretty in the sudoers file. I sthe answer to get the unix team to not set this default or change it to not require tty?

[root@caclasd05 ~]# grep NAGIOS /etc/sudoers
[root@caclasd05 ~]# grep requiretty /etc/sudoers|grep nagios
[root@caclasd05 ~]# grep requiretty /etc/sudoers
Defaults requiretty
# changed in order to be able to use sudo without a tty. See requiretty above.

All of this is supposed to be in /etc/sudoers on an XI system

Thanks Scott. I will get this added to the sudoers file. We did try to find the nagios.sudoers file mentioned in a kb doc. Is there also any documents on what permissions the nagios user needs to have or files it is meant to own and run instead of root?

cheers

The file mentioned in the doc can really only be found in a source install. the details above should outline all the requirements of nagios to run as root

Thanks Scott, your sudoers content fixed the running issues, I am no longer getting the errors and everything appears to be now in a running state. We will move onto setting things up to monitor and snmp traps receiving. Thanks again for all your help. This can be closed as fixed.
