Daneben gibt es noch die speziellen Variablen APACHE2_MODULES und APACHE2_MPMS, die bestimmen, welche Apache-Module und welche MPMs (Multi-Processing Modules) im späteren Einsatz zur Verfügung stehen. Das ganze kann man in der make.conf festlegen.
... APACHE2_MPMS="worker" ...
Und das ganze installieren:
emerge -qa net-analyzer/nagios net-analyzer/nagios-plugins-snmp net-analyzer/nagios-plugins
* APACHE * The location of SSL certificates has changed. If you are * upgrading from www-servers/apache-2.2.13 or earlier (or remerged * *any* apache version), you might want to move your old * certificates from /etc/apache2/ssl/ to /etc/ssl/apache2/ and * update your config files. * * Attention: cgi and cgid modules are now handled via APACHE2_MODULES flags * in /etc/make.conf. Make sure to enable those in order to compile them. * In general, you should use 'cgid' with threaded MPMs and 'cgi' otherwise. PHP * Please note that this version of PHP does not yet come with a suhosin patch * Installing SAPI: cli * Installing php.ini for cli into /etc/php/cli-php5.3 * * Installing SAPI: cgi * Installing php.ini for cgi into /etc/php/cgi-php5.3 * * Installing SAPI: apache2 * Installing php.ini for apache2 into /etc/php/apache2-php5.3 * * * To enable php, you need to edit your /etc/conf.d/apache2 file and * add '-D PHP5' to APACHE2_OPTS. * * * Configuration file installed as * /etc/apache2/modules.d/70_mod_php5.conf * You may want to edit it before turning the module on in /etc/conf.d/apache2 * * Switched cli to use php:5.3 * * Switched cgi to use php:5.3 * * Switched apache2 to use php:5.3 * * Make sure that PHP_TARGETS in /etc/make.conf includes php5-3 in order * to compile extensions for the 5.3 ABI * * * This ebuild installed a version of php.ini based on php.ini-development version. * You can chose which version of php.ini to install by default by setting PHP_INI_VERSION to either * 'production' or 'development' in /etc/make.conf * Both versions of php.ini can be found in /usr/share/doc/php-5.3.6

Man kann zusätzliche Berechtigungen in folgender Datei übergeben
nano /etc/apache2/modules.d/99_nagios3.conf
Wir bleiben hier aber bei „Allow from all“
Jetzt erstellen wir den Apache authorization table. Hierzu legen wir jeweils eine „.htaccess“ in folgenden Verzeichnissen an:
Pfad |
nano /usr/share/nagios/htdocs/.htaccess |
nano /usr/lib/nagios/cgi-bin/.htaccess |
Der Inhalt der Datei soll so aussehen:
AuthName "Nagios Access" AuthType Basic AuthUserFile /etc/nagios/auth.users Require valid-user
Jetzt legen wir den Nagiosbenutzer für das Webinterface an:
htpasswd2 -c /etc/nagios/auth.users nagiosadmin (Apache needs read access to auth.users) chown nagios:nagios /etc/nagios/auth.users
Zuerst müssen wir unseren default VHOST festlegen.
nano /etc/apache2/vhosts.d/00_default_vhost.conf ... <VirtualHost *:80> ServerName localhost Include /etc/apache2/vhosts.d/default_vhost.include <IfModule mpm_peruser_module> ServerEnvironment apache apache </IfModule> ScriptAlias /nagios/cgi-bin /usr/lib/nagios/cgi-bin <Directory "/usr/lib/nagios/cgi-bin"> Options ExecCGI AllowOverride None AllowOverride AuthConfig Order allow,deny Allow from all </Directory> Alias /nagios /usr/share/nagios/htdocs <Directory "/usr/share/nagios/htdocs"> Options Indexes AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> </IfDefine> ...
Jetzt noch die erforderlichen Dienste neu starten:
/etc/init.d/nagios restart && /etc/init.d/apache2 restart
Jetzt kann man sich über http://nagios-test.darkwolf.lan/nagios einloggen.
