Red Hat 7

Redhat 7 Installation

Introduction

Please check that the assumptions and requirements documented in the installation overview have been suitably completed.

RHEL Subscriptions

Enable the Extra Packages for Enterprise Linux (EPEL) repository:

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

N-Squared Yum Package Repository

N-Squared provides a RPM repository that is used to provide a number of dependencies that otherwise are not available through standard channels (particularly the n2svcd package itself).

In order to use this repository, set up the N-Squared RHEL yum repository by creating a record for it in the file:

vi /etc/yum.repos.d/nsquared.repo

Add the following content to the file with access credentials that are provided by N-Squared:

[nsquared]
gpgcheck=0
enabled=1
name=N-Squared Software Releases
baseurl=https://<username>:<password>@www.nsquared.nz/rpm/rhel/7

Clean all the existing repositories to update yum:

yum clean all

Update the available repositories to refresh the available package list:

yum update

Note that organisational security or operational guidelines might require our repository to be accessed through a local satellite repository, rather than direct as shown here.

Pre-Requisite Packages

The n2svcd package has a number of pre-requisites.

Install core packages:

yum install epel-release lua lksctp-tools \
rsyslog nano rsync rsyslog-snmp net-snmp-libs \
policycoreutils-python sysstat

Note the usage of epel-release; this core package acts as yum repository extension package that allows access to additional Perl packages that would otherwise require manual installation.

Install core Perl packages:

yum install \
    perl-DBI \
    perl-JSON \
    perl-Time-HiRes \
    perl-Test-Differences \
    perl-Module-Load \
