Port notes

************************************************************
The basic steps to complete the installation are below. But Nagios is a complex program so you should read the documentation online at https://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 -s
for i in *cfg-sample; do mv $i `echo $i | sed -e s/cfg-sample/cfg/`; done;
exit

c) Configure the default commands.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" to browse all hosts/services 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' Apache user/password to correspond with the Nagios Apache user created above

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

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

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

Lock file: ${prefix}/var/nagios/nagios.lock
Init file: ${prefix}/var/nagios/nagios.init
HTML URL: http://localhost/nagios/
CGI URL: http://localhost/nagios/cgi-bin/ A startup item has been generated that will aid in starting nagios with launchd. It is disabled by default. Execute the following command to start it, and to cause it to launch at startup:

sudo port load nagios
