32     <uri link="http://www.jffnms.org">Jffnms</uri> is a network management and
33     monitoring system. It allows you to grab information from many different kinds
34     of hosts and protocols. With this guide, we aim to show you how to get Jffnms
35     properly installed and have your systems monitored by this amazing tool.

80     <p>
81     Being written in PHP, Jffnms is heavily dependent on php USE Flags. In order
82     to install Jffnms successfully, it is required that you have your php package
83     installed with (at least) the following USE flags:

120 neysx 1.1 <title>Installation</title>
121     <body>
122    
123     <p>
124     Just like any package in Portage, jffnms can be installed with <c>emerge</c>:
125     </p>
126    
127     <pre caption="Installing Jffnms">
128     # <i>emerge jffnms</i>
129     </pre>
130    
131     <p>
132     Jffnms should be installed in <path>/opt/jffnms/</path>.
133     </p>
134    
135     </body>

137     <section>
138     <title>Configuring Apache 2</title>
139     <body>
140    
141     <warn>
142     This very basic configuration procedure for apache does not cover all aspects
143     of setting up a web server.
144     </warn>
145    
146     <p>
147     Sometimes you will want to run Jffnms on your local computer instead of a
148     remote server. If this is your case, it is very likely that you don't have an
149     apache setup running. Don't worry about installing apache though, Portage has
150     already done that for you. Nevertheless, you still have to configure and test
151     apache, which (luckily) is pretty straightforward. Start by adding apache to
152     your default runlevel:
153     </p>
154    
155     <pre caption="Adding apache 2 to the default runlevel">
156     # <i>rc-update add apache2 default</i>
157     * apache2 added to runlevel default
158     * rc-update complete.
159     </pre>
160    
161     <p>
162     If you haven't done it yet, it's time to start apache2:
163     </p>
164    
165     <pre caption="Starting apache2">
166     # <i>/etc/init.d/apache2 start</i>
167     </pre>
168    
169     <p>
170     Finally, point your browser at <uri>http://localhost/</uri> and you should be
171     presented with a home page about your newly installed Apache 2. Now that we
172     know that Apache is up and running, we can proceed to the mod_php
173     configuration. Fire up your favorite text editor, open
174     <path>/etc/conf.d/apache2</path> and add <c>-D PHP4</c> the APACHE2_OPTS
175     variable.
176     </p>
177    
178     <pre caption="Apache 2 Configuration">
179     # <i>nano -w /etc/conf.d/apache2</i>
180     APACHE2_OPTS="-D DEFAULT_VHOST -D PHP4"
181     </pre>
182    
183     <p>
184     After that, you should create a symlink to the Jffnms install directory in your
185     Apache document root dir. In Gentoo, by default, Apache uses
186     <path>/var/www/localhost/htdocs</path> as document root. So, you should do the
187     following:
188     </p>
189    
190     <pre caption="Creating Jffnms symlink">
191     # <i>cd /var/www/localhost/htdocs &amp;&amp; ln -s /opt/jffnms/htdocs</i>
192     </pre>
193    
194     </body>
195     </section>
196     <section>
197     <title>Configuring PHP</title>
198     <body>
199    
200     <p>
201     Now that apache is running, it is time to configure PHP. Jffnms requires that
202     you set some variables in php.ini in order to run. The php.ini file is usually
203     located in <path>/etc/php/apache2-php4/php.ini</path>. You have to set these
204     variables to the following values:
205     </p>
206    
207     <pre caption="Configuring PHP">
208     # <i>nano -w /etc/php/apache2-php4/php.ini</i>
209     register_globals = On
210     register_argc_argv = On
211     error_reporting = E_ALL &amp; ~E_NOTICE
212     allow_url_fopen = On
213     include_path = ".:/usr/share/php4:/usr/share/php:/usr/share/php/PEAR"
214     short_open_tag = On
215     </pre>
216    
217     </body>
218     </section>
219     <section>
220     <title>Database setup</title>
221     <body>
222    
223     <warn>
224     Please note again that this a very basic configuration procedure for any
225     database system and does not cover all aspects of setting up such systems.
226     </warn>
227    
228     <p>
229     Jffnms allows you to use either PostgreSQL or MySQL as its database. Here we'll
230     show you how to create the database and necessary tables where Jffnms will
231     store its data. It's important to note that it isn't necessary to have a
232     database running localy to run Jffnms and except for the fact that you need to
233     run this commands on the remote host, the procedure is the same.
234     </p>

238     <section>
239     <title>Setting Up PostgreSQL</title>
240     <body>
241    
242     <note>
243     If you already have a PostgreSQL database up and running, you can proceed to
244     the <uri link="#use-pg">next section</uri>.
245     </note>
246    
247     <p>
248     You should add PostgreSQL to your default runlevel so it's started each time
249     you boot your computer.
250     </p>
251    
252     <pre caption="Adding PostgreSQL to the default runlevel">
253     # <i>rc-update add postgresql default</i>
254     * postgresql added to runlevel default
255     * rc-update complete.
256     </pre>
257    
258     <p>
259 nightmorph 1.4 Now you must setup the PostgreSQL database.
260 neysx 1.1 </p>
261    
262 nightmorph 1.4 <pre caption="Preparing PostgreSQL">
263     # <i>emerge --config postgresql</i>
264 neysx 1.1 </pre>
265    
266     <p>
267 nightmorph 1.4 Now start PostgreSQL:
268 neysx 1.1 </p>
269    
270     <pre caption="Starting PostgreSQL">
271     # <i>/etc/init.d/postgresql start</i>
272     </pre>

276     <section id="use-pg">
277     <title>Using PostgreSQL as database</title>
278     <body>
279    
280     <p>
281     Once you have your PostgreSQL set up and running, you have to create a Jffnms
282     user and a database to store host data. We provide files to do both.
283     </p>
284    
285     <note>
286     If you don't use <path>/usr/portage</path> as your portage dir ($PORTDIR) you
287     have to change the last part of these commands to whatever your portage dir
288     is.
289     </note>
290    
291     <pre caption="Creating Jffnms user">
292     # <i>psql template1 postgres &lt; /usr/portage/net-analyzer/jffnms/files/postgresql_db</i>
293     </pre>
294    
295     <pre caption="Creating Jffnms database">
296 neysx 1.3 # <i>psql template1 postgres &lt; /usr/portage/net-analyzer/jffnms/files/postgresql_db_table</i>
297 neysx 1.1 </pre>
298    
299     <p>
300     Finally, you need to create all the tables where data will be stored:
301     </p>
302    
303     <pre caption="Creating Jffnms database">
304     # <i>psql jffnms jffnms &lt; /opt/jffnms/docs/jffnms-0.8.2.pgsql</i>
305     </pre>
306    
307     <p>
308     Once you have run those steps, PostgreSQL database configuration for Jffnms
309     should be ok.
310     </p>

319     Installing and configuring a MySQL database is not covered in this guide.
320     Please see our <uri link="/doc/en/mysql-howto.xml">MySQL Startup Guide</uri>.
321     </warn>
322    
323     <p>
324     In case you want to run Jffnms with MySQL, the process is a bit simpler. We
325     provide two files to create database, user and tables for MySQL.
326     </p>
327    
328     <note>
329     If you don't use <path>/usr/portage</path> as your portage dir ($PORTDIR) you
330     have to change the last part of these commands to whatever your portage dir
331     is.

352    
353     <p>
354     If you want UDP port monitoring and discovery, you need to set <c>nmap</c> and
355 rane 1.2 <c>fping</c> as a SUID programs. This may give you security hole in case
356 neysx 1.1 there's a bug in one of them. To set them as a SUID you can run the following

391     <p>
392     By now, Jffnms should be correctly installed on your system. You still need,
393     however, to configure Jffms. Luckily, Jffnms provides us with an easy to use
394     web page where it's possible to configure access to database, user access as
395     well as check if the current host configuration suffices Jffnms needs. You can
396     access this web interface through the following URL:
397     <uri>http://localhost/jffnms/admin/setup.php</uri>. You should visit <uri
398     link="http://www.jffnms.org/">Jffnms's home page</uri> for details on how to
399     properly configure it.
