Installing openNMS on RedHat using rpm.

I am assuming postgres database is already installed.

download the following rpm.

• openNMS core :
  opennms-core-1.8.5-1.noarch.rpm
•  jetty for opennms :
  opennms-webapp-jetty-1.8.5-1.noarch.rpm 
• Jicmp  from here depending upon the the architecture. for example :
  (jicmp-1.0.6-1.fc8.i386.rpm)
  http://rpmfind.net/linux/rpm2html/search.php?query=jicmp&submit=Search+...&system=&arch=

 now installing process...
rpm -ivh opennms-core-1.8.5-1.noarch.rpm
rpm -ivh  jicmp-1.0.6-1.fc8.i386.rpm
rpm -ivh opennms-webapp-jetty-1.8.5-1.noarch.rpm


stop postgres database if it is running
/etc/init.d/postgresql stop

To allow OpenNMS to connect to the database, you will need to edit your database's  
pg_hba.conf file. On many default installations it can be found in the directory
/var/lib/pgsql/data/

local   all   all                      ident sameuser
host    all   all    127.0.0.1/32      ident sameuser
host    all   all    ::1/128           ident sameuser

You will need to change these entries to resemble the following: 

local   all   all                      trust

host    all   all    127.0.0.1/32      trust

host    all   all    ::1/128           trust

Next, you will need to edit postgresql.conf to accept TCP/IP 

connections. As with pg_hba.conf, check the defaults or your 

distribution's PostgreSQL documentation for the location of 

this file. As before, on many default installations it can 

be found in the directory /var/lib/pgsql/data/ Both 

postgresql.conf and pg_hba.conf by default should be 

in the same location.

....

#listen_addresses = 'localhost'

 ....

uncomment this line to resemble

....

listen_addresses = 'localhost'

 ....

start the postgres db..
/etc/init.d/postgresql start


go to /opt/opennms/bin/ (default installation dir for opennms)

run the install script...
#>install



after that start opennms

#>opennms start

open http://localhost:8980/opennms/index.jsp

and enjoy...:)
