Installing the PostgreSQL database and the OpenNMS management platform on two different servers allows you to spread the load.
1. Installation of the PostgreSQL server
2.1 Changing the administrator password
2.2 Optimization of the database
2.3 Authorizing the OpenNMS server to connect
3. Installation of the OpenNMS server
5. First connection to OpenNMS
1. Installation of the PostgreSQL server
Download a version of OSE from the Download page.
Use your preferred burning utility to burn the DVD ISO just downloaded.
Insert the DVD in your drive and boot the computer from the DVD-ROM drive.
The following screen appears:

2.3 Authorizing the OpenNMS server to connect
To authorize connections from the OpenNMS server to the database, type the following command:
Replace the string 192.168.56.101/24 with the IP address of the OpenNMS server followed by the mask.
2.4 Restarting PostgreSQL
To restart PostgreSQL, type the following command:
3. Installation of the OpenNMS server
Download a version of OSE from the Download page.
Use your preferred burning utility to burn the DVD ISO just downloaded.
Insert the DVD in your drive and boot the computer from the DVD-ROM drive.
The following screen appears:
Type opennms and press Enter.
Now follow the procedure for installation described in Installation in standalone mode.
4. Configuring OpenNMS
4.1 Configuration
