OpenNMS, the latest network management tool in Linux

OpenNMS, the latest network management tool in Linux
GuideOpenNMS is a carrier-level, highly integrated, open source platform for building network monitoring solutions. OpenNMS has two releases: Meridian and Horizon. It is advisable to use Meridian to provide stable and long-term support for enterprises. Horizon is a fast and innovative release of new monitoring technologies and new IT ecosystem. These two distributions are completely open-source.

1. OpenNMS installation preparation

Environment: CentOS 7.2

Update Source:

yum -y install yum-plugin-priorities epel-release centos-release-scl-rh centos-release-sclyum update -y

Http://www.opennms.org/en

Official wiki: http://wiki.opennms.org/wiki/Installation:Yum

Uninstall opennms Source: https://yum.opennms.org/repofiles/opennms-repo-RELEASE-DISTRIBUTION.noarch.rpm

root@linuxprobe[11:09:27]:/usr/local/src$wget http://yum.opennms.org/repofiles/opennms-repo-stable-rhel7.noarch.rpmroot@linuxprobe[11:09:27]:/usr/local/src$rpm -ivh opennms-repo-stable-rhel7.noarch.rpmroot@linuxprobe[12:51:26]:~$rpm --import http://yum.opennms.org/repofiles/OPENNMS-GPG-KEY

2. Install the database for OpenNMS

# Installing PostgreSQL

yum -y install postgresql-server

# Initialize PostgreSQL

postgresql-setup initdb

# Modify postgrasql. conf

root@linuxprobe[08:56:17]:~$vim /var/lib/pgsql/data/postgresql.conf

# Line 59: set to allow all addresses to access psotgresql

listen_addresses = '*'

# Line 395: Set the log format

log_line_prefix = '%t %u %d '

# Psotgresql start and set automatic start upon startup

root@linuxprobe[08:56:37]:~$systemctl start postgresql && systemctl enable postgresql

3. PostgreSQL settings

# Allow users to access the database

root@linuxprobe[09:15:44]:~$sed -i 's/all 127\.0\.0\.1\/32 ident/all 127.0.0.1\/32 trust/g' /var/lib/pgsql/data/pg_hba.confroot@linuxprobe[09:28:45]:~$sed -i 's/all ::1\/128 ident/all ::1\/128 trust/g' /var/lib/pgsql/data/pg_hba.conf

# Restart PostgreSQL

root@linuxprobe[09:29:06]:~$systemctl restart postgresql

4. Install JDK

# Install java 8 for OpenNMS 16

# Jdk: http://www.oracle.com/technetwork/java/javase/downloads

# Upload to the server/usr/local/src

root@linuxprobe[10:23:45]:/usr/local/src$rpm -ivh jdk-8u101-linux-x64.rpm

5. Install OpenNMS

root@linuxprobe[12:51:26]:~$yum install opennms –y

# Configure java

root@linuxprobe[14:02:33]:~$/opt/opennms/bin/runjava -S /usr/java/latest/bin/javarunjava: checking specified JRE: "/usr/java/latest/bin/java"...runjava: specified JRE is good.runjava: value of "/usr/java/latest/bin/java" stored in configuration file

6. Create or update an opennms Database

root@linuxprobe[14:06:07]:~$/opt/opennms/bin/install -dis

#-D. update the database

#-I import data

#-S creates a stored procedure for OpenNMS

7. IPLIKE Configuration

# OpenNMS uses PostgreSQL's "iplike" stored procedure to provide an API to easily perform complex IP address queries. By default, a version of iplike is installed, which is compatible with all versions of OpenNMS. We recommend that you use yum for performance considerations.

yum -y install iplike

# View iplike help

/usr/sbin/install_iplike.sh –h

8. Firewall settings

# Enable port

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8980 -j ACCEPT

# Disable Firewall

/sbin/service iptables stopsystemctl disable iptables

# Restart iptables

/sbin/service iptables restart

9. Start OpenNMS and access it in the browser

systemctl opennms restart
