Apart from what seemed to be installed by default, these packages were installed using yast2 (some of these packages might not make sense in a NAV context, but were installed as extra tools during the server preparation):
This will install required software that is not available from yast2.

First, run this command to install the NAV rpm:
rpm -ivh nav-3.0*.noarch.rpm
In addition to installing NAV, this should create the group nav and the user navcron. NAV's SMS Daemon runs as the navcron user, so you need to make sure that the navcron user is permitted to write to the system's serial ports. If you set up your phone on /dev/ttyS0, check to see which group has write permissions to that device, and add the navcron user to that group (On SLES, this is typically the uucp group).
Initialize the database using the recipe from
/usr/local/nav/doc/sql/README. Use this file whenever you are
installing NAV. For upgrading use the correct script from
nav/doc/sql/upgrades/.
The password for tha nav-user should be set by using the instructions in this document. If you need to alter the password this can be done by:
psql template1 ALTER USER nav WITH PASSWORD 'foo'; \q exit
Configure NAV to use these passwords. Changes made to
/usr/local/nav/etc/db.conf:
# # PostgreSQL user passwords. # userpw_nav=foo
We need to be able to connect to PostgreSQL using TCP/IP, and we
should enable statistics to allow pg_autovacuum to do database
maintenance. Make sure these settings are present in
/var/lib/pgsql/data/postgresql.conf:
tcpip_socket = true stats_start_collector = true stats_row_level = true
And these in pg_hba.conf in the same directory:
local all postgres ident sameuser local all all md5 host all all 127.0.0.1 255.255.255.255 md5 host all all ::1 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff md5
We will not assign a password for the postgres user here, but instead
we will demand ident sameuser authentication for the postgres user
and grant sudo access to database administrators to perform commands
as the postgres user. This means a database administrator on the
server can execute sudo -u postgres psql manage to enter SQL
commands in the NAVdb, regardless of whether he/she has root access to
the server.
We restart PostgreSQL (still as root) and start pg_autovacuum (which
should really be started as part of /etc/init.d/postgresql):
/etc/init.d/postgresql restart su -c "pg_autovacuum -D" postgres
Configure PostgreSQL to automatically start when the server is restarted:
chkconfig postgresql on
The RPM packages provided by the NAV team does not install NAV in the
preferred layout of the distribution, but rather puts everything into
/usr/local/nav. Therefore, we will need to employ a few tricks to
make the NAV libraries easily available to all programs on the server
(you are free to contribute a .spec file with an alternate
installation layout!).
In preference to building a long, ugly CLASSPATH, we symlink all the .jar-files of NAV in the the running JVM's library directory:
cd $JAVA_HOME/jre/lib/ext ln -s /usr/local/nav/lib/java/*.jar .
Also you need to symlink in the postgres and snmp-drivers. There were
linked to /usr/local/nav/lib/java.
In preference to setting a PYTHONPATH environment variable pointing to
the NAV Python libraries, we fix sys.path by creating the file
usr/lib/python2.3/site-package/sitecustomize.py and placing this
code in it:
import sys
sys.path.append('/usr/local/nav/lib/python')
This will make sure that the NAV python libraries are available to all running Python programs on the server, without the need to install these libraries in the library directories of Python.
As with the Java libraries, we create a few symlinks to the perl libraries (although this is not as straightforward as symlinking the .jar files). Assuming the Perl version on your system is 5.8.3, we do:
cd /usr/lib/perl5/site_perl/5.8.3 ln -s /usr/local/nav/lib/perl/NAV.pm ln -s /usr/local/nav/lib/perl/NAV ln -s /usr/local/nav/lib/perl/NetAddr
Tomcat needs the postgres-driver as well. It was linked to
/usr/lib/SunJava2-1.4.2/jre/lib/ext.
The example Apache 2 configuration from the NAV source tree (http://svn.itea.ntnu.no/repos/nav/navme/trunk/doc/apache/httpd2.conf.example) was used as a basis, and the relevant parts were placed into SuSE's Apache 2 configuration structure.
We recommend installing an SSL server and redirect all non-SSL requests to this server (so all web server traffic, including passwords, are encrypted).
Restart Apache2 and configure it to automatically start when the server is restarted:
/etc/init.d/apache2 restart chkconfig apache2 on
We configure Tomcat to only listen to the local interface, and the NAV
servlets nee d to be symlinked in to the webapps directory. Edited
/etc/tomcat/base/server.xml so the following was present:
<!-- Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" address="127.0.0.1"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true" />
NAV's servlets are then symlinked:
cd /usr/share/tomcat/webapps ln -s /usr/local/nav/apache/webapps/*.war .
Next, symlink the .jar files as well:
cd /usr/share/tomcat/shared/lib ln -s /usr/local/nav/lib/java/*.jar .
Restart Tomcat and configure it to automatically start when the server is restarted:
/etc/init.d/tomcat restart chkconfig tomcat on
'Please note that this part is not yet complete and needs to be revised
to make sure that server statistics are collected.'
The user navcron was created by the RPM package, and should have had
its HOME set to /usr/local/nav. The NAV integration of Cricket
will have it running as the user navcron and not cricket, as the
documentation of Cricket would normally suggest. Run:
chgrp nav /usr/local/nav chmod g+sw /usr/local/nav wget http://belnet.dl.sourceforge.net/sourceforge/cricket/cricket-1.0.3.tar.gz su navcron mkdir ~/cricket cp cricket-1.0.3.tar.gz ~/cricket/ cd ~/cricket tar xvzf cricket-1.0.3.tar.gz ln -s cricket-1.0.3 cricket cd cricket sh configure cp cricket-conf.pl.sample cricket-conf.pl
Edit cricket-config.pl so that it contains the following lines:
package Common::global; $gCricketHome = "/usr/local/nav/cricket"; $gInstallRoot = "$gCricketHome/cricket"; $gConfigRoot = "$gCricketHome/cricket-config"; $gDbAccess = "slurp"; # Slurp the database into memory
Then we create directories for the configuration- and data trees of Cricket, and for the web cgi script:
cd ~/cricket mkdir public_html cd public_html ln -s ../cricket/images ln -s ../cricket/grapher.cgi ln -s ../cricket/lib ln -s ../cricket/mini-graph.cgi ln -s ../cricket/VERSION ln -s grapher.cgi index.cgi cp /usr/local/nav/doc/cricket/public_html/cricket.css . mkdir ../cricket-data ln -s ../cricket-data cp -r /usr/local/nav/doc/cricket/cricket-config .. ln -s ../cricket-config cd ~/cricket/cricket cp /usr/local/nav/doc/cricket/cricket/* .
Finally, you may initialize the Cricket configuration (event though no IP devices have been registered in NAV yet):
cd ~ cricket/cricket/compile bin/makecricketconfig.pl exit
For Cricket to be visible on the web, do the following Apache configuration steps as root:
cd /usr/local/nav/apache/webroot ln -s ~navcron/cricket/public_html cricket cd cricket echo "SetHandler none" > .htaccess
This will tell Apache not to use the mod_python handler in this directory.
NAV's configuration files are in /usr/local/nav/etc. We've
already made some changes to db.conf to make sure NAV can connect
to PostgreSQL. Now we need to adjust some essential values of
nav.conf and webfront/webfront.conf before we are ready for
launch.
Except for the comments, this is the short version of what needs to be set:
ADMIN_MAIL = <your NAV administrator's e-mail address here!> DOMAIN_SUFFIX = <your domain suffix here> AUTO_CREATE_DEVICE = yes NAVROOT=/usr/local/nav JAVA_HOME = /usr/lib/java
If you would like NAVs web interface to use LDAP authentication, you can set this up here. Also, many users prefer longer session timeouts, which can also be configured here.
In order to get Alertprofiles to work properly you need to patch forgetSQL with the patch found in contribs in the NAV-source. If you forget this, the alertprofiles webinterface will randomly hang because of a deadlock in the database.
