Sudo issue

[alperkar]

Hi There,

This script does not seem to be working in RHEL or it's just me :)

When I have the following setting (with SUDO) in zabbix_agentd.conf:

UserParameter=mdraid[*], sudo /usr/local/bin/zabbix_mdraid.sh -m'$1' -$2'$3'
UserParameter=mdraid.discovery, sudo /usr/local/bin/zabbix_mdraid.sh -D

And execute the following from Zabbix proxy:

zabbix_get -s HOSTNAME -k mdraid[/dev/md0,d,1]

I am getting the following error ("sorry, you must have a tty to run sudo") in zabbix_agentd.log:

25547:20141229:090259.961 Requested [mdraid[/dev/md0,d,1]]

Yes, I have already tweaked /etc/sudoers file:

/etc/sudoers:
zabbix ALL=(ALL) NOPASSWD: ALL

Defaults:zabbix !requiretty

Any ideas how to make this work?

[linuxsquad]

You are on the right path. Try to comment out the entire line:

Defaults:zabbix !requiretty
and search throu the /etc/sudoers to make sure there is no other line with requiretty

[alperkar]

Defaults:zabbix !requiretty -> this actually means do not require tty for user zabbix
But I have commented out all requiretty lines just in case. Still the same issue. when I switch to zabbix user and run the script it works. It does not work when the command is initiated by the zabbix agent... It says tty is required but according to sudoers it is not?

[linuxsquad]

odd... What distro version are you running this zabbix agent on?
Oh... make sure that zabbix_agentd runs under zabbix user ID.

[alperkar]

Zabbix agent runs under zabbix user:

zabbix 30980 0.0 0.2 76888 1348 ? S Dec30 0:00 zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf

Distro:
[/etc] # cat /etc/system-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)

[linuxsquad]

Sorry, wanted to check on the same server ... but none of them run zabbix with sudo enabled.

[linuxsquad]

Do you have selinux enabled?

[alperkar]

selinux in permissive mode.

[linuxsquad]

were you able to resolve this issue?

[alperkar]

Unfortunately, no. Had to use a different, more primitive solution.

[linuxsquad]

I found RHEL 6.5 where i can test it, give me some time.

[yogionwindows]

well when I am trying to import the template for zabbix 2.4 its not getting imported
