*** Compile finished ***

If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type ‘make’
without any arguments for a list of all possible options):

make install
– This installs the main program, CGIs, and HTML files

make install-init
– This installs the init script in /etc/init.d

make install-commandmode
– This installs and configures permissions on the
directory for holding the external command file

make install-config
– This installs *SAMPLE* config files in /usr/local/nagios/etc
You’ll have to modify these sample files before you can
use Nagios. Read the HTML documentation for more info
on doing this. Pay particular attention to the docs on
object configuration files, as they determine what/how
things get monitored!

make install-webconf
– This installs the Apache config file for the Nagios
web interface

make install-exfoliation
– This installs the Exfoliation theme for the Nagios
web interface

make install-classicui
– This installs the classic theme for the Nagios
web interface
*** Support Notes *******************************************

If you have questions about configuring or running Nagios,
please make sure that you:

– Look at the sample config files
– Read the documentation on the Nagios Library at:

Nagios Library

before you post a question to one of the mailing lists.
Also make sure to include pertinent information that could
help others help you. This might include:

– What version of Nagios you are using
– What version of the plugins you are using
– Relevant snippets from your config files
– Relevant error messages from the Nagios log file
