Changing the Eggplant DAI Port on Windows

Although Eggplant DAI assigns port 8000 by default during installation, you can specify a different port later:

1. Open C:\ProgramData\Eggplant\Digital Automation Intelligence\settings.ini.
   Important: The C:\ProgramData folder might not be initially visible, as it is hidden by default.
2. Find the [settings] section. Update the line server_port=8000 to include the port you want to use.
3. Save your work.
4. Restart the Digital Automation Intelligence Windows service.

Upgrading from Eggplant AI 3.1 to Eggplant DAI 4.0.1 on Windows

If you're upgrading from Eggplant AI 3.1, then follow these steps after installing Eggplant DAI 4.0.1:

1. Locate the Digital Automation Intelligence service in the Windows Services panel and stop it.
2. Copy over all the Postgres data files and folders from your original location (e.g., C:\eggplantAI\pgsql\data) to the Eggplant DAI location (e.g.,C:\ProgramData\Eggplant\Digital Automation Intelligence\data).
Important:
• The C:\ProgramData folder might not initially be visible, as it is a hidden folder by default.
• Copy all files and subfolders. When prompted, overwrite the existing files in the destination.
3. From the Windows Services panel, start the Digital Automation Suite service.

Uninstalling Eggplant DAI on Windows

Use the following instructions for uninstalling Eggplant DAI.

1. Locate and run the Eggplant DAI uninstall program by choosing Start > All Programs > Uninstall Eggplant DAI.
2. Click Yes when prompted to uninstall Eggplant DAI and all its components.
3. Click OK after the removal process is done.

Uninstalling Eggplant DAI does leave some folders intact. Note that the data that's left behind after you uninstall Eggplant DAI contains user account information, user models, and execution data. Only remove these files and folders if they are no longer required. Assuming you installed Eggplant DAI in the C:/Program Files/ DAI directory, the following folders remain if you need to retain any files:

Eggplant AI data directory files: C:\ProgramData\Eggplant\Digital Automation Intelligence\data

Server and Eggplant DAI log files: C:\ProgramData\Eggplant\Digital Automation Intelligence\logs

If you decide that you want to do a complete Eggplant DAI removal after following the above steps to uninstall Eggplant DAI, delete the following directory or folder:

C:\Program Files\Digital Automation Intelligence

Installing Eggplant DAI on Linux

1. Download dai-installer-4.0.1.run (installation package) from the Eggplant website.
2. Run the installation (binary) package:

sudo ./dai-installer-4.0.1.run

The binary package includes Nginx and PostgreSql, which are installed in their standard locations. The Eggplant DAI application is installed in the /opt/eggplant/dai folder, with logs in the /var/log/eggplant/dai folder.

The binary package also installs the following systemd services relevant to Eggplant DAI, which enables and starts them as part of the post-installation script:

Active by default:
• dai-api: The main REST API of the product

• dai-composer: Supports API Proxy to allow better UI integration

• dai-engine-wrapper: Supports proxy to allow scheduled executions

• dai-ml: Machine learning service
• dai-server: Supports Eggplant DAI runs

• dai-sut: Allows the definition of SUTs to be used by the scheduler and configuration services

• dai-task-scheduler: Supports proxy to allow scheduled executions

• dai-test-config: Allows the definition of test configurations to be executed

  Note: Although dai.service is active by default after installing Eggplant DAI, it will not be listed along with the other services.

Inactive by default (requires manual setup):
• dai-ri-engine: The main engine for Release Insights
• dai-ri-connectors: Release Insights analysis connectors
Third-party services
• nginx: The main HTTP server for Eggplant DAI
• postgresql-9.6: Supports PostgreSQL service for Eggplant DAI

For more information about systemd services, see RHEL's official documentation.

Configuration

Eggplant DAI configuration files are in its default folder location: /etc/nginx/conf.d/.

This folder contains configuration files for Nginx:

eggplant-dai.conf: Includes a sample standard Eggplant DAI nginx configuration. See the official NGINX documentation for more details.

For information about configuring Insights data, contact Eggplant support.

SELinux

Eggplant DAI has been tested to work with the default Security-Enhanced Linux (SELinux) in permissive mode. SELinux enables system admins to define and access transition rights of users, application, process, and files in a Linux environment. If you suspect a possible issue, disable SELinux temporarily and include the results of running without SELinux for reporting the problem to Eggplant support.

Changing the default port after installing Eggplant DAI on Linux

Although Eggplant DAI assigns port 8100 by default during installation, you can specify a different port later:

1. Stop the Nginx service:
sudo systemctl stop nginx
2. Rename the default.conf file and move it to the previous folder (inactive):
mv /etc/nginx/conf.d/default.conf /etc/nginx/default.conf.old
3. Edit the eggplant-dai.conf file that's located in the following directory:
vim /etc/nginx/conf.d/eggplant-dai.conf
4. In the eggplant-dai.conf file, locate the following line:

listen 8100;listen [::]: 8100;

Replace it with your preferred port (if it is free), for e.g., if your new port is 8101, then change it to:

listen 8101;listen [::]: 8101;
5. Verify if the updated port works as expected by testing it:
sudo nginx -t

Note: If you receive warnings about SELinux in permissive mode, follow these steps for enabling ports:

Check SELinux Http ports:

sepolicy network -t http_port_t

Check if the port is available:

sepolicy network -p 8001

Activate port in SELinux:

semanage port -a -t http_port_t -p tcp 8001

6. Activate the Nginx service:
sudo systemctl start nginx

For information on how to configure Nginx, see the official NGINX documentation.

7. Save the changes.
