The installation of PNP is controlled by <a href="http://de.wikipedia.org/wiki/makefile" class="interwiki iw_wpde" title="http://de.wikipedia.org/wiki/makefile">makefile</a>s. The system is analyzed after invocation of ./configure and the detected values are tranferred to makefiles.

|

|

<p>
|

Please unpack PNP as user root:

|
|
|

</p>
|
||
|
|
<pre class="code">
|

tar -xvzf pnp4nagios-HEAD.tar.gz

|

|
|
</pre>
|
||
|
|
|
||
|
|
<p>
|

./configure is to be called from the directory pnp4nagios.

<pre class="code">

<p>
|
||
|
|
|
||
|
|
<strong>Note:</strong> Without specifying any options user and group will be “nagios”. If you have different values then please use the parameters ”--with-nagios-user” and ”--with-nagios-group”, respectively. Using Icinga the call might be

After the installation of the program and <acronym title="HyperText Markup Language">HTML</acronym> files you can copy a sample Apache configuration file to your web-server config directory
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<pre class="code"> make install-webconf</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
You can call
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<pre class="code"> make install-config</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
optionally. This way config files for process_perfdata.pl and npcd are copied to etc/pnp.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
To install the NPCD Init script call
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<pre class="code"> make install-init</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
All these steps are combined in
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<pre class="code"> make fullinstall</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<strong>Note:</strong> As already stated the Nagios settings will be used per default. If you are using Icinga the file '/etc/apache2/conf.d/pnp4nagios.conf' has to be edited to change the path to AuthUserFile (the path may differ between distributions):
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<pre class="code"># AuthUserFile /usr/local/nagios/etc/htpasswd.users
|
||
|
|
AuthUserFile /usr/local/icinga/etc/htpasswd.users</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
<strong>Attention:</strong> After copying the configuration file for the web server you have to restart the web server (<code>service httpd restart</code> or <code>/etc/init.d/apache2 restart</code>, respectively).

||

The update of a 0.6.x version works (nearly) the same way as an installation. Please note that you have to call <code>./configure</code> with the same options you used during the first installation.
|
||
|
|
Please check if you changed anything in the folder <code>share/templates.dist</code>. Own templates should be placed in <code>share/templates</code> to avoid being overwritten.<br/>
|
||
|
|
|
||
|
|
<strong>Attention</strong>: If you changed config.php then you should save this file before it is overwritten when you execute <code>make install-config</code>.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
You can skip <code>make install-webconf</code> and <code>make install-init</code> because nothing changed between 0.6.x versions.
