To Configure OpenNMS
Run the following command to update the repository.
root@linuxhelp:/home/user1# cat < < EOF | sudo tee /etc/apt/sources.list.d/opennms.list
> deb http://debian.opennms.org stable main
> deb-src http://debian.opennms.org stable main

Next lets permit the User Access to the database by editing the configuration file.
root@linuxhelp:/home/user1# nano /etc/postgresql/9.5/main/pg_hba.conf
Find the following lines:
local all all local
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
And, replace local and md5 to trust which will finally look like the following:
local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust
Then restart the postgresql service by running the following command.
root@linuxhelp:/home/user1# service postgresql restart
First add the repository by running the following command.

Q
Tomcat won't start, complains about JAVA_HOME, why?
A
Sun had released a new version of the 1.4 JDK since the 1.0.0 RPMs were built. If you install that JDK, Tomcat will probably complain about JAVA_HOME. Edit /etc/tomcat4/conf/tomcat4.conf to correctly show the path to your JAVA_HOME.
Q
Someone told me to change OpenNMS configure the data collector to "store by group", how do I do that?
A
Create a file called opennms.conf in the $OPENNMS_HOME/etc directory (if you haven't already) and add this entry:
ADDITIONAL_MANAGER_OPTIONS=-Dorg.opennms.rrd.storeByGroup=true
ADDITIONAL_MANAGER_OPTIONS=-Dorg.opennms.rrd.storeByGroup=true
Q
Why does apt complain about zebra and gated?
A
If you get the following error
Sorry, but the following packages have unmet dependencies:
gated: Obsoletes: zebra but 0.91a-6 is to be installed
zebra: Obsoletes: gated but 3.6-12 is to be
Q
opennms.sh status returns nothing, what's happening?
A
Make sure that you have curl installed on your system.
