Need help to Install Nagios XI in an offline environment? We can help you.

As part of our Server Management Services, our knowledgeable techs help customers deploy Nagios XI.

Today, let us see how our Support Engineers go about this installation.

Prerequisites to Install Nagios XI Offline

Nagios Enterprises can only support installing Nagios XI on a newly installed, clean system.

The server must have access to base repositories for both RedHat or CentOS either via a local repository, or mounted DVD’s.

Additionally, on RHEL systems we will need the following packages from the Optional Channel installed on the server:

RHEL 6 Optional Channel Packages

graphviz-gd.x86_64
perl-IO-stringy.noarch
perl-Parse-RecDescent.noarch
perl-XML-Simple.noarch
php-mbstring.x86_64
php-snmp.x86_64
rrdtool-perl.x86_64
rrdtool-python.x86_64

RHEL 7 Optional Channel Packages

dejavu-lgc-sans-fonts.noarch
dejavu-lgc-sans-mono-fonts.noarch
graphviz-gd.x86_64
perl-Crypt-DES.x86_64
perl-Parse-RecDescent.noarch
php-mbstring.x86_64
php-snmp.x86_64

Download and Install Nagios XI Offline

We begin by visiting https://repo.nagios.com/?repo=offline and download the Nagios XI Offline RPM Tarball for distribution and architecture.

Then, we transfer the downloaded tarball to the server we will be installing Nagios XI on, place the tarball in /tmp/rpms/.

We execute the following commands to install Nagios XI. We need to replace the tarball file name below with the file downloaded:

# cd /tmp/rpms
# tar xzf nagiosxi-5-4.7.el7.x86_64.tar.gz
# cd nagiosxi
# ./fullinstall

Once the installation completes, we will be able to navigate to our server via a browser to complete the installation.

http://<YOUR_SERVER>/nagiosxi/

Due to the nature of RPM-based installs, there will be a simple message that states the installation is complete.

Upgrading Nagios XI

The procedure for upgrading an offline installation of Nagios XI is almost exactly the same as the installation procedure.

First, we visit https://repo.nagios.com/ and download the Nagios XI Offline RPM Tarball for distribution and architecture.

Then, we transfer the downloaded tarball to the server we will be performing an upgrade of Nagios XI on, place the tarball in /tmp/rpms/

We execute the following commands to upgrade Nagios XI. We should replace the tarball filename below with the file we downloaded:

# cd /tmp/rpms
# tar xzf nagiosxi-5-4.7.el7.x86_64.tar.gz
# cd nagiosxi
# ./upgrade

Once the upgrade completes, we navigate to the server via a browser: http://<YOUR_SERVER>/nagiosxi/

Due to the nature of RPM-based installs, there will be a simple message that states the upgrade is complete.
