Install OpenNMS on openSUSE 12.2

Install OpenNMS on OpenSUSE 12.2

Problem is, RPM packages are provided for RHEL/Centos/Fedora, but not Suse. There is also a general installation, so I use this

Install JDK > 1.5

Oracle java is recommended, but I will try openjdk 1.7 since I already have it installed.

# javac -version
javac 1.7.0_15

Install Postgres

• There is a postgresql for OpenSUSE, so I will install that one

zypper install postgresql postgresql-server
insserv postgresql

Make sure locale uses utf8: either POSTGRES_LANG in /etc/sysconfig/postgresql is empty and RC_LANG in /etc/sysconfig/language ends with .UTF-8 or POSTGRES_LANG ends with .UTF-8 (e.g. en_US.UTF-8) If you don't have this and you already started postgresql once (database is already created), then you have to dump it (stop postgresql, save config in ~postgres/data, then remove data add the .UTF-8 and restart postgresql which initializes the db again, restore your saved config changes selectively and restart postgresql again). This will destroy data in the database, so take care you have a backup if needed.

• Create config files by starting postgres once

rcpostgresql start

• Configure postgresql access as described on openNMS page

su - postgresql
cd data
vi pg_hba.conf

We will need to have these linees (usually change last words to trust):

local   all         all                               trust
host    all         all         127.0.0.1/32          trust
host    all         all         ::1/128               trust

vi postgresql.conf

Add listen_address to enable tcpip and not just socket access and increase some limits

listen_addresses = 'localhost'
max_connections = 512
shared_buffers = 128MB
temp_buffers = 32MB

Now restart postgresql

rcpostgresql restart

Install iplike

sudo zypper install postgresql-devel rpm-build
wget http://sourceforge.net/projects/opennms/files/IPLIKE/stable-2.0/iplike-2.0.3.tar.gz
tar xzf iplike-2.0.3.tar.gz
cd iplike-2.0.3
./configure
make rpm
sudo rpm -ihv ~/rpmbuild/RPMS/x86_64/iplike-2.0.3-1.x86_64.rpm

Install jicmp

wget http://sourceforge.net/projects/opennms/files/JICMP/stable-1.4/jicmp-1.4.0.tar.gz
wget http://sourceforge.net/projects/opennms/files/JICMP6/stable-1.2/jicmp6-1.2.0.tar.gz
rpmbuild --nodeps -tb --target=x86_64 jicmp-1.4.0.tar.gz
rpmbuild --nodeps -tb --target=x86_64 jicmp6-1.2.0.tar.gz
sudo rpm -ihv ~/rpmbuild/RPMS/x86_64/jicmp-1.4.0-1.x86_64.rpm ~/rpmbuild/RPMS/x86_64/jicmp6-1.2.0-1.x86_64.rpm

--nodeps required because openjdk is not detected

Install OpenNMS

jdk 1.7 not supported for build yet (compile errors)

That's why I built it on openSUSE 12.1 where jdk 1.6 is standard and then copied the rpm's to the 12.2 system.

• On buildhost with openSUSE 12.1

wget http://sourceforge.net/projects/opennms/files/OpenNMS-Source/stable-1.10.8/opennms-source-1.10.8-1.tar.gz
tar xzf opennms-source-1.10.8-1.tar.gz 
cd opennms-1.10.8-1
find . -name *.spec -exec sed -i 's/^BuildRequires/# BuildRequires/' {} \;
./makerpm.sh
scp -r target/rpm/RPMS/noarch targetnode:/tmp/

Comment out BuildRequires because jdk dependency is not recognized

• On targetnode with openSUSE 12.2

sudo rpm -ihv /tmp/noarch/*.rpm

First Start of OpenNMS

cd /opt/opennms
./bin/runjava -s
./bin/install -dis
sudo -u postgres /usr/sbin/install_iplike.sh
./bin/opennms start

First Login

Now start browsing at

http://localhost:8980/opennms/

login as admin with pw admin (change that soon! Click on the username top right and then on change password)

I recommend doing the tutorial now to set up basic monitoring.

Capability scanning works best if discovered devices run snmp. For servers you can:

• install net-snmp
• enter syslocation and syscontact in /etc/snmp/snmpd.conf
