HI Team,

I am trying to install Nagios Network analyzer on Centos 7.1 host, we are ending up with an error while installation. I have attached a copy of Installation log for your reference. Any help on this ?

Package php-common-5.4.16-36.el7_1.x86_64 already installed and latest version
Nothing to do
nagiosna step completed OK
Running 'backend'...

Running 'db'...
Redirecting to /bin/systemctl start mariadb.service
Failed to issue method call: Unit mariadb.service failed to load: No such file or directory.

Check for error messages in the install log (install.log).

If you require assistance in resolving the issue, please include install.log

It looks like you are trying to install NNA on an unsupported platform. The install log shows you are using CentOS 7.1.1503.
Build 1503 is not available as a minimal install at the CentOS website:

Note : " Nagios Enterprises highly recommends and will only support installing Nagios Network Analyzer on a newly installed,
“clean” system (a bare minimal install with nothing else installed or configured). "

--refer to our installation doc for NNA:
