This method should take care of dependency installation for you.

If installing from source using this guide:

https://support.nagios.com/kb/article.php?id=515#CentOS

Have you followed the instructions under Prerequisites?

I need to troubleshoot the repositories.

yum repolist

ls  /etc/yum.repos.d/

/etc/yum.repos.d/

Extra Packages for Enterprise Linux 7

That's right. What is the output of:

Code: Select all

yum repolist

and

Code: Select all

ls  /etc/yum.repos.d/

Please navigate to:

Code: Select all

/etc/yum.repos.d/

Then nano into epel.repo
Find:

Code: Select all

Extra Packages for Enterprise Linux 7 

and make sure that enabled is set to 1

Then nano into the nagios-7.repo
And make sure that [nagios-base] and [nagiosxi-deps] has enabled = 1.

1). Disabled our local repo and then renamed the <local>.repo file.
2). Got the latest Public Repo and then enabled that .repo file.
3). Updated and then upgraded all that was needed.
4). Installed gcc, etc. as per the 2nd document link information.
5). Installed the linux-nrpe-agent doing an interactive install/setup.

This works now.

Problem that I will encounter: The non-interactive (unattended) install for the linux-nrpe-agent assumes some defaults (that appear to be RedHat chosen). Since I'm not using RedHat, what are the defaults that I need to modify (other than adding my own Nagios XI's server's IP in the "install.sh" file). I noticed that the "get-os-info" script uses command "lsb-release", however, that is not installed on Oracle Enterprise Linux 7.x.

it appears that the linux-nrpe-agent uses a command, lsb_release, that derives from RedHat somehow. I find this to be quite frustrating. I may have to re-engineer or be forced to install the lsb_release package. UGH!

which lsb_release
/usr/bin/which: no lsb_release in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)

ls -la /etc/oracle-release
-rw-r--r--. 1 root root 32 Aug  4  2017 /etc/oracle-release

sed 's/.*release \([0-9.]\+\).*/\1/' /etc/redhat-release
7.4

# Get OS & version
if which lsb_release &>/dev/null; then
	distro=`lsb_release -si`
	version=`lsb_release -sr`
elif [ -r /etc/redhat-release ]; then

	if rpm -q centos-release; then
		distro=CentOS
	elif rpm -q sl-release; then
		distro=Scientific
	elif [ -r /etc/oracle-release ]; then
		distro=OracleServer
	elif rpm -q cloudlinux-release; then
		distro=CloudLinux
    elif rpm -q fedora-release; then
		distro=Fedora
	elif rpm -q redhat-release || rpm -q redhat-release-server; then
		distro=RedHatEnterpriseServer
	fi >/dev/null

	version=`sed 's/.*release \([0-9.]\+\).*/\1/' /etc/redhat-release`
else
	# Release is not RedHat or CentOS, let's start by checking for SuSE
	# or we can just make the last-ditch effort to find out the OS by sourcing os-release if it exists
	if [ -r /etc/os-release ]; then
		source /etc/os-release
		if [ -n "$NAME" ]; then
			distro=$NAME
			version=$VERSION_ID
		fi
	fi
