Arch Linux User Repository

@mosh5382 I've had the php7 binary moved away for over a week and haven't noticed anything weird yet. Please let me know if you upgrade and/or run into problems.

I don't actually use check_by_ssh, so yeah, you might need the home directory in your case then.

@Rhinoceros - I was unable to tell conclusively if PHP 7.4 was a requirement. The official Nagios documentation is unclear however I was unable to find any mention of Nagios and PHP 8. A lot of non-Arch distributions ship outdated versions of PHP so this may be more of an issue for Arch users only. My Nagios machine is a VM so I will certainly snapshot it before trying an upgrade to PHP 8.

I was able to get the email notifications working with s-nail. I suspected there was a way to get this working without the /home/nagios directory for the email configuration. However, what about "check_by_ssh"? Won't the ssh keys have to be in the /home/nagios/.ssh directory for it to work?

@mosh5382 AFAIK php 7 isn't required by nagios. It's certainly not in the PKGBUILD dependencies. Also, php 7 is not in the AUR.

Because of this, I haven't been game enough to uninstall php 7 yet, but I've moved the binary away, and nagios appears to still work fine.

Also, the email notifications work fine for me without creating a home directory, but my mail config is perhaps setup different to yours. I use s-nail with opensmtpd. Also check /etc/nagios/objects/contacts.cfg. There's also this old issue, but it should be fixed now. Just check

$ ls -l /usr/bin/smtpctl
-r-xr-sr-x 1 root smtpq 168280 Nov  1 19:19 /usr/bin/smtpctl

I just installed this and I have some words of warning for anyone trying to install it new. Nagios generally seems to be in a rough state (not the PKGBUILD which works well). As best I can tell PHP 7 is required which is unsupported by the PHP developers. PHP 7 can be installed via the AUR.

One suggestion on the PKGBUILD. I was unable to get the email notifications to work without creating a home directory for the nagios users. I used the "s-nail" package to do email relay, I couldn't find another method. In this setup Nagios sends notification mail from the Nagios users and I needed to put the configuration files for email relay in /home/nagios. This was difficult to do because the PKGBUILD creates the nagios user as a system user. Google can help you get a proper home directory setup for the nagios user even if they aren't allowed to login. This was the only way I found to get the email notifications working and I did work on the notifications for a while!

Chown warning fixed. Thanks @Rhinoceros.

Thanks for updating, @Idares. One minor issue, I get the warning when building

chown: warning: '.' should be ':': ‘nagios.nagios’

Looks like a typo in the PKGBUILD, which can be fixed with the following

diff --git a/PKGBUILD b/PKGBUILD
index 4371a24..5fa3bec 100644

Thanks @Idares. That works perfectly.

@Rhinoceros, @nachfuellbar: the openssl package in core was changed from version 1.x to v3. Try to rebuild nagios package with latest openssl installed (without openssl-1.1).

As per the comment nine days ago, this also fails for me until I install openssl-1.1. @Idares could you please add this as a dependency?

Again, I can see that it's been a bit hard for you to keep updating this package regularly. Again, I'm happy to maintain this package if you like.

Seems like there were changes in Arch because after System Update today i got a error from nagios process about missing libssl.so.1.1. /usr/bin/nagios: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory After installing openssl-1.1 it's working again (should be made a dependency if it's really necessary)
