Striker Database Setup

Create DB:

su - postgres -c "createdb --owner striker scanner"

Password:

The SQL files we need to load are found in the /etc/striker/SQL directory.

The core SQL file is

ls -lah /etc/striker/SQL/

total 64K

Note: The default is that the database owner name is striker. If you used a different database name owner, please update the .sql files with the command sed -i 's/striker/yourname/' *.sql.

Load the SQL tables into the database.

cat /etc/striker/SQL/*.sql > /tmp/all.sql
psql scanner -U striker -f /tmp/all.sql

Password for user striker:

<sql load messages>

Test:

psql -U striker -d scanner -c "SELECT * FROM alert_listeners"

Password for user striker:

Configure Scan Core on a Node

Install dependencies:

yum install Scanner postgresql

On the clients, you need to be sure your configuration files are set the way you want.

Most importantly is that the connection details to the databases on the dashboards are configured properly. Most installs have two dashboards, and Scanner will record it's data to both for resiliency.

The configuration files are found in /etc/striker/Config/.

ls -lah /etc/striker/Config/

-rw-r--r--. 1 root root 1.4K Mar  4 23:41 system_check.conf

Note: We're showing two databases, but in theory, there is no set limit on the number of database servers that the nodes can use. Simply copy the configuration section for each additional server you wish to use. Just be sure to increment the id number for each section (ie: db::X::name where X is a unique integer for the additional server).

In this example, the two Striker dashboards with our databases have the BCN IPs 10.20.4.1 and 10.20.4.2. Both use the database name scanner owned by the database user striker with the password secret. So their configurations will be nearly identical.
