• Install everything. Metron REST will probably not work as we still need to add a user and the database to MySQLMariaDB.
  At this point, make sure that all the services are up. You might have to manually start a few.

• Configure a user for Metron REST in MySQL. On the node where you installed the Metron REST UI, do:

...

# mysql -u root -p
CREATE USER '<DB USERNAME>'@'localhost' IDENTIFIED BY '<DB PASSWORD>';
CREATE DATABASE IF NOT EXISTS <DB NAME>;
GRANT ALL PRIVILEGES ON <DB NAME>.* TO '<DB USERNAME>'@'localhost';

...

# mysql -u root -p
> CREATE USER 'metron'@'localhost' IDENTIFIED BY 'metron';
> CREATE DATABASE IF NOT EXISTS metronrest;
> GRANT ALL PRIVILEGES ON metronrest.* TO 'metron'@'localhost';
> quit
Bye
# 

...

• There's 1 last step we need to do before the metron REST service will run. Due to systemd in Centos 7, doing service metron-rest start <PASSWORD> no longer works. Instead we have to edit the configuration file "`/etc/rc.d/init.d/metron-rest`". In this file, change `METRON_JDBC_PASSWORD="$2"` to `METRON_JDBC_PASSWORD="<DB PASSWORD>"` and restart the metron-rest service via the Ambari interface. Make sure that the Metron REST UI is started when moving to the following item.

...

Change: "supervisor.slots.ports: [6700, 6701]" to "supervisor.slots.ports: [6700, 6701, 6702, 6703, 6704, 6705]"

• Install Apache NiFi in /root (You can pretty much use any directory you want). Download nifi-1.2.0-bin.tar.gz from https://nifi.apache.org/download.html

# cd /root
# wget http://apache.mirror.iweb.ca/nifi/1.2.0/nifi-1.2.0-bin.tar.gz
# tar xf nifi-1.2.0-bin.tar.gz
