Sudo check-barman "no such file to load -- rbarman"

[bernard-c]

Hello,

I have an error when I try to execute the check with the user nagios and sudo :

-sh-4.1$ whoami
nagios
-sh-4.1$ sudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -h /opt/data/MSA/barman -s KBILL-SAP
/usr/lib64/nagios/plugins/check-barman/check-barman.rb:26:in `require': no such file to load -- rbarman (LoadError)
from /usr/lib64/nagios/plugins/check-barman/check-barman.rb:26

However, I have the rbarman gem installed :

-sh-4.1$ gem list rbarman

*** LOCAL GEMS ***

rbarman (0.0.13, 0.0.12)

And in sudoers file, I followed your advice and I added these lines :

Defaults:nagios !requiretty
nagios ALL=NOPASSWD: /usr/lib64/nagios/plugins/check-barman/check-barman.rb

And when I list gem with the command sudo, I also add rbarman gem :

-sh-4.1$ sudo gem list rbarman

*** LOCAL GEMS ***

rbarman (0.0.13, 0.0.12)

Isn't there something missing in your documentation to use check-barman with sudo command and nagios user?

What do you get if you execute it without sudo?

-sh-4.1$ vim /usr/lib64/nagios/plugins/check-barman/check-barman.rb

Because, I do not have the right to execute 'barman' with nagios user :

-sh-4.1$ barman status KBILL-SAP
ERROR: please run barman as 'barman' user

I can execute barman with sudo, but it's not compatible with your code :)

-sh-4.1$ sudo /usr/bin/barman status KBILL-SAP
Server KBILL-SAP:
Description: KBILL-SAP PostgreSQL Database

Yes, that's ok, just wanted to know if gem could be found. So it seems to be a problem with sudo.
Could you paste your /etc/sudoers? Which distribution?

[hamann]

You're using rvm?

[hamann]

I'm not familiar with rvm, but you should have a look at https://rvm.io/integration/sudo

[bernard-c]

Thank you, this link https://rvm.io/integration/sudo helped me.

I added this line on sudoers file :

Defaults env_keep +="rvm_bin_path GEM_HOME IRBRC MY_RUBY_HOME rvm_path rvm_prefix rvm_version GEM_PATH rvmsudo_secure_path RUBY_VERSION rvm_ruby_string rvm_delete_flag PATH"

And commented out this :

Defaults secure_path

Then, I added this line on bash_profile user :

export rvmsudo_secure_path=0

And, with rvmsudo command, I can execute the plugin to check barman :

-sh-4.1$ rvmsudo /usr/lib64/nagios/plugins/check-barman/check-barman.rb -a pg -h /opt/data/MSA/barman -s KBILL-SAP
PG connection ok

Thank you for your help !
