Minimum Requirements
--------------------
* A 1 GHz Pentium III (or equivalent processor) or better. OpenNMS can also take advantage of multiple processors.
* A minimum of 256 MB of RAM, although 512 MB is strongly recommended. The OpenNMS Java Virtual Machine benefits from large amounts of memory, up to 2 GB, and more if using a 64-bit processor.
* OpenNMS requires about 200 MB of disk space for the program files. In addition, each data variable collected requires, by default, a little under 300 KB of disk space.
Configure RPM-based Distributions with Yum
-------------------------------------------
[root@localhost ~]# yum install yum-fastestmirror
Install the OpenNMS Repository RPM
-----------------------------------
rpm -Uvh http://yum.opennms.org/repofiles/opennms-repo-snapshot-fc7.noarch.rpm
Or, to install the latest unstable release on CentOS or RHEL 5, you would run:
rpm -Uvh http://yum.opennms.org/repofiles/opennms-repo-unstable-rhel5.noarch.rpm
Installing Java on RPM-based Distributions Using Yum
----------------------------------------------------
[root@localhost ~]# yum install jdk
Installing PostgreSQL on RPM-Based Distributions Using Yum
----------------------------------------------------------
[root@localhost ~]# yum -y install postgresql-server
Configure PostgreSQL
--------------------
Locate the Postgres "data" directory. Often this is /var/lib/pgsql/data. You should then find the two files we need to modify in that directory.
First we need to make sure PostgreSQL is listening on an IP socket, and not just a local unix socket.
Edit postgresql.conf File and add the following.
listen_addresses = 'localhost'
max_connections = 256
max_connections = 256
Customizing the pg_hba.conf File
--------------------------------
Add the below lines.
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
local all all trust
host all all 127.0.0.1 255.255.255.255 trust
host all all ::1 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust
Creating the PostgreSQL Database
---------------------------------
# /etc/init.d/potgresql start
Installing JICMP on RPM-Based Distributions Using YUM
-----------------------------------------------------
[root@localhost ~]# yum install jicmp
Installing OpenNMS
------------------
------------------
[root@localhost ~]# yum install opennms-*
Configure Java for OpenNMS
--------------------------
[root@localhost ~]# /opt/opennms//bin/runjava -s
The desired outpu is given below:
runjava: Looking for an appropriate JRE...
runjava: Checking for an appropriate JRE in JAVA_HOME...
runjava: skipping... JAVA_HOME not set
which: no java in (/usr/lib/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/opennms/bin:/root/bin)
runjava: did not find a JRE in user's path
runjava: searching for a good JRE...
runjava: found a good JRE in "/usr/java/jdk1.5.0_18/bin/java"
runjava: value of "/usr/java/jdk1.5.0_18/bin/java" stored in configuration file
You have new mail in /var/spool/mail/root
Configure a specific JRE
-------------------------
If you need to configure specific JRE do the following:
[root@localhost]# /opt/opennms/bin/runjava -S
Run the OpenNMS Installer Application
-------------------------------------
[root@localhost ~]# /opt/opennms/bin/install -l /usr/local/lib -dis
Login to the Web Application
-----------------------------
By default, OpenNMS's built-in web server listens on port 8980, so point your browser at http://
The initial user name is "admin" and the password is "admin".
