	               ************************************************************
		  The basic steps to complete the installation are below.  But Nagios is
		  a complex program so you should read the documentation online at
		  http://www.nagios.org or locally at ${prefix}/share/nagios/docs/index.html
		  to fully understand Nagios.
		           ************************************************************                      

IMPORTANT: A user and group called 'nagios' has been created and you must run
	   nagios as that user.



1) Setup Apache's httpd.conf file for Nagios (restart Apache when done)
        
   Insert the \"Nagios stuff\" text block somewhere *above* your Apache cgi-bin
   ScriptAlias statement:

	ScriptAlias /cgi-bin/ \"/Library/WebServer/CGI-Executables/\"

#
# Nagios stuff
 
ScriptAlias /nagios/cgi-bin/ \"${prefix}/sbin/nagios/\"
<Directory \"${prefix}/sbin/nagios\">
 AllowOverride None
    Options ExecCGI
    Order allow,deny 
    Allow from all
    AuthName \"Nagios Access\"
    AuthType Basic
    AuthUserFile ${prefix}/etc/nagios/htpasswd.users
    require valid-user
</Directory>
 
Alias /nagios \"${prefix}/share/nagios\"
<Directory \"${prefix}/share/nagios\">
    Options None
    AllowOverride AuthConfig
    Order allow,deny
    Allow from all
</Directory>
 
# End Nagios stuff
#


2) Configure the Nagios sample files in ${prefix}/etc/nagios.

a) First, backup the Nagios sample files.

   cd ${prefix}/etc/nagios
   sudo mkdir sample
   sudo cp *.cfg-sample sample/

b) Then rename the sample files for use.

   sudo for i in *cfg-sample; do mv \$i `echo \$i | sed -e s/cfg-sample/cfg/`; done;

c) Configure the minimal.cfg file to your requirements.  Then test
   the Nagios configuration with this command until you get no errors:

   sudo nagios -v ${prefix}/etc/nagios/nagios.cfg


3) Set user 'nagiosadmin' as a \"superuser\" in ${prefix}/etc/nagios/cgi.cfg

   authorized_for_system_information= nagiosadmin
   authorized_for_configuration_information= nagiosadmin
   authorized_for_system_commands= nagiosadmin
   authorized_for_all_services= nagiosadmin
   authorized_for_all_hosts= nagiosadmin
   authorized_for_all_service_commands= nagiosadmin
   authorized_for_all_host_commands= nagiosadmin


4) Create a 'nagiosadmin' user/password for administator Nagios webpage access

	htpasswd -c ${prefix}/etc/nagios/htpasswd.users nagiosadmin

   Create other users as desired, omit '-c' since it creates the password file.  Make
   additional users login names match Nagios contact names to restrict web viewing to your
   host's by contact.


5) Set Nagios to start at system boot, and start Nagios

   OS X 10.4 - Run launchctl so Nagios will start at system boot
	sudo launchctl load -w /Library/LaunchDaemons/org.macports.nagios.plist

   OS X 10.3 - A startup item was created in /Library/StartupItems
	Add \"NAGIOS=-YES-\" to the /etc/hostconfig file to run Nagios at system boot

   You may now start Nagios manually with this command (or a reboot):
	sudo ${prefix}/var/nagios/nagios.init start


6) You may now login as 'nagiosadmin' to the Nagios web interface at http://localhost/nagios


NOTE: The SMTP server Postfix is required to enable Nagios email notifications
