tip

The steps and commands were performed on Ubuntu 18.

Environment check​

Perform an environment check for the following:

  • Hostname-IP address resolution

  • Firewall settings

  • Steps and commands performed in Ubuntu 18

Prerequisites​

Install and configure the following software:

  • Java

  • PostgreSQL with empty vae database

  • Apache Tomcat

  • Apache ActiveMQ

Make necessary changes to set up the Ubuntu environment.

AE installation​

For AE installation, create a directory structure and database for AE, and deploy Automation engine and UI war files on Tomcat server.

Create AE directory structure​

Create the top-level directory, AE Base Directory in which all AE software and components are installed. You need to create the following directories and setup AE_HOME environment variable:

AutomationEdgeBase 🡪 \preferred_drive\AutomationEdge.

For example, /home/username/Automationedge

AutomationEdge Tools 🡪 \preferred_drive\AutomationEdge/tools.

For example, /home/username/Automationedge/tools

AutomationEdge Home 🡪 preferred_drive:/AutomationEdge/aehome.

For example, /home/username/Automationedge/aehome

Set environment variable​

AE_HOME= "\path for the AE working directory\".

For example, AE_HOME=/home/username/Automationedge/aehome

War files deployment​

Perform the following steps to deploy war files:

  1. Use the following command to change the directory to webapps:

cd "/home/user_name/AE_Tools/apache-tomcat-10.1.30/webapps"

  1. Use the following command to delete all out-of-the-box apps directories or files or folders from the webapps directory.

rm -rf \*

  1. Copy AE war files to the webapps directory.
tip

Use WinSCP tool if you are copying from Windows to Linux.

  1. Use following command to rename aeengine.war as follows:

mv aeengine-8.0.0.war aeengine.war

  1. Use following command to rename aeui.war as follows:

mv aeui-8.0.0.war aeui.war

  1. Ensure the following are running:

i. ActiveMQ: Start using super user credentials.

ii. PostgreSQL service.

tip

If Postgres DB user password is different, change it in file /tools/automationedge/conf/database.properties.

ii. Tomcat: Start using super user credentials.

tip

Restart the Tomcat service so that .war files get extracted in webapps directory, and database is populated with objects.
