Installing Arrowhead on a Debian based Linux distribution

Currently, this guide is known to work on Ubuntu Server 18.04, but it will likely work on other version and Debian based Linux distribution also. The following is a quick guide on the essentials.

1. Install Linux

Do a normal installation of Linux, and remember to update afterwards:

sudo apt update && sudo apt dist-upgrade

2. Install MySQL

Pick one of the options below.

2a. MySQL 5.x (Ubuntu)

Install:

sudo apt install mysql-server

Check if running:

sudo netstat -tap | grep mysql

2b. MySQL 8.x (Oracle)

First, get the latest repository package from https://dev.mysql.com/downloads/repo/apt/, eg.:

wget https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb
sudo apt update

To install the MySQL server, run:

sudo apt install mysql-server

NOTE: The Arrowhead installers use MySQL root user to create database tables, users and privileges for the Arrowhead core systems, so if the database and the core system is not on the same machine you have to make sure that MySQL root user has remote access.

Login to the machine where the database is located and start the mysql command line interface:

mysql -uroot -p

After typing the password use the following SQL commands to enable remote access:

CREATE USER 'root'@'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Exposing root user to every host is a HUGE SECURITY RISK so we recommend revoking the remote root access after the installation is done:

DROP USER 'root'@'%';

3. Install Java

Ubuntu users (and others?):

sudo apt install openjdk-11-jre-headless

NOTE: Install JDK version instead of JRE version, if you plan to build the latest Debian Packages from source, using Maven. You just need to change the "-jre-" part to "-jdk-" in the package name. JDK needs more disk space. JRE versions can only run packaged Java applications, but can not build them from source code.

Check Java version:

java -version

4. Download/install Arrowhead

Pick one of the options below.

4a. Download Arrowhead Debian Packages

Check the GitHub site https://github.com/arrowhead-f/core-java-spring-installers/tree/master/packages for the latest packages and download them:

wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-core-common_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-authorization_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-choreographer_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-eventhandler_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-gatekeeper_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-gateway_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-orchestrator_4.1.3.deb
wget -c  https://github.com/arrowhead-f/core-java-spring-installers/raw/master/packages/arrowhead-serviceregistry_4.1.3.deb

NOTE: The arrowhead-core-common package is a requirement for all other packages.

4b. Build Arrowhead Debian Packages

NOTE: To compile Arrowhead yourself, you should have both the JDK and Maven installed.

To build the Debian packages yourself, start by cloning the repository:

git clone https://github.com/arrowhead-f/core-java-spring.git -b development

Build them with:

mvn package

Copy all the packages to your Arrowhead server (you may have to start SSH server on it first with sudo systemctl start ssh:

scp target/arrowhead-*.deb X.X.X.X:~/

5. Install Arrowhead Core Debian Packages

Go to the folder where you copied the packages and then:

sudo apt install ./arrowhead-*.deb

The installation process will show prompts asking for input parameters. Certificate passwords need to be at least 6 character long!

After the process is done, please see the log files in the /var/log/arrowhead folder. If any of the installed systems failed to start (because the Service Registry was unreachable at the time when they try to connect to it), please reboot the failed core system manually by using sudo systemctl start arrowhead-<core system name>.service You can find the service files in the /etc/systemd/system folder.

The created services will restart on reboot.

6. Hints

Add a new application system

You can use the script ah_gen_system_cert to generate certificate (and trust store) to a system.

sudo ah_gen_system_cert SYSTEM_NAME PASSWORD SYSTEM_HOST SYSTEM_IP

SYSTEM_NAME and PASSWORD are mandatory parameters. The other two are the DNS name and IP address of the computer that running the system. If SYSTEM_HOST and SYSTEM_IP are not specified, the command assumes the system is running on the local machine. Examples:

sudo ah_gen_system_cert client1 123456 abc.com 10.0.0.22

sudo ah_gen_system_cert localsystem1 123456

A new directory is generated in your current directory which is named SYSTEM_NAME. Generated certificates will appear in this directory.

Add a new relay

You can use the script ah_gen_relay_cert to generate certificate (and trust store) to a ActiveMQ relay.

sudo ah_gen_relay_cert RELAY_NAME PASSWORD RELAY_MASTER_CERT RELAY_MASTER_PASSWORD RELAY_HOST RELAY_IP

RELAY_NAME, PASSWORD, RELAY_MASTER_CERT (path to the relay master certificate .p12 file) and RELAY_MASTER_PASSWORD are mandatory parameters. The other two are the DNS name and IP address of the computer that running the relay. If RELAY_HOST and RELAY_IP are not specified, the command assumes the relay is running on the local machine. Examples:

sudo ah_gen_cert relay1 123456 ./relay-master.p12 654321 abc.com 10.0.0.22

sudo ah_gen_cert relay1 123456 ./relay-master.p12 654321

A new directory is generated in your current directory which is named RELAY_NAME. Generated certificates will appear in this directory.

Other hints

Log files (log4j2) are available in: /var/log/arrowhead/*

Output from systems are available with: journalctl -u arrowhead-*.service

Restart services: sudo systemctl restart arrowhead-\*.service

Configuration and certificates are found under: /etc/arrowhead

Generated passwords can be found in application.properties files located in /etc/arrowhead/systems/ directory.

Mysql database: sudo mysql -u root, to see the Arrowhead tables:

use arrowhead;
show tables;

apt purge can be used to remove configuration files, log files, etc. Use sudo apt purge arrowhead-\* to remove everything arrowhead related. Please note the database tables and users will not deleted by the purge.
