NagiosXI install fail: [Errno 256] No more mirrors to try

Question

I'm trying to install NagiosXI.5.5.8 on a fresh VM image of RHEL7.6 minimal install. It fails on the step 1 of running ./fullinstall with an error of [Errno 256] No more mirrors to try.

Answer 1

It looks like the nagios-7.repo repo in /etc/yum.repos.d is incorrect. It is looking for an http url but nagios is using https.

nagios-7.repo:

[nagios-base]
name=Nagios
baseurl=http://repo.nagios.com/nagios/7/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-NAGIOS-V2

[nagiosxi-deps]
name=Nagios XI Dependencies
baseurl=http://repo.nagios.com/nagiosxi-deps/7/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-NAGIOS-V2

This seems to work:

[nagios-base]
name=Nagios
baseurl=https://repo.nagios.com/nagios/7/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-NAGIOS-V2

[nagiosxi-deps]
name=Nagios XI Dependencies
baseurl=https://repo.nagios.com/nagiosxi-deps/7/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-NAGIOS-V2
