# Linux installation

This topic describes how to install Micro Focus Connect on a Linux machine.

You can install Micro Focus Connect to run as a background service, which is the standard installation, or as a standalone application, commonly used when trying out the product.

Note: Micro Focus Connect for Linux is distributed as a tgz/tar.gz bundle, but not in a Linux package manager format such as RPM or DEB. Therefore, installation, uninstallation, and upgrades require manual intervention. Only attempt these actions if you have extensive knowledge in Linux.

In this topic:

## Installation types

Beginning with version 4.5, for on-premises environments, you can install Micro Focus Connect as a standalone installation or a multi-node installation.

- Standalone installation. This option performs a full installation of the Micro Focus Connect service and the database service on same machine, as in previous releases. This type of installation does not allow other machines to access the database.

- Multi-node installation. This option allows you to install the database service on a separate machine. You can then install the Micro Focus Connect server nodes on multiple machines, all accessing the same database.

## Before you install Micro Focus Connect

For all installation types, perform the following before you install Micro Focus Connect on a Linux machine:

1. Check the Support Matrix to make sure that your environment is supported.
2. Download Micro Focus Connect Core for Linux from the AppDelivery Marketplace.

3. Create a folder for the Connect installation, and unpack the files from the downloaded archive:

   gunzip mfconnect-linux-<build>.tar.gz

   tar -xvf mfconnect-linux-<build>.tar.gz

4. If you are upgrading an existing installation, stop any connections that are running in the existing installation, to prevent data loss.

Tip: For an overview of the Micro Focus Connect system resource utilization and other installation considerations, see Windows installation. Instead of the Windows Task Scheduler, use cron jobs to schedule your tasks.

## Perform a full Linux installation

This section describes how to perform a full standalone installation of Micro Focus Connect.

To perform a full installation:

1. For multi-server node installations only: Set the database to an open connection:

   1. Change the directory to the installation's Database/bin folder.

   2. Open the <installPath>/Database/bin/setenv file and change the value of the derby.drda.host system variable from 127.0.0.1 to the relevant private network. For details, see the Derby documentation.

2. Change the directory to the deployment folder:

   cd MicroFocusConnect

3. Run the database configuration:

   ./configure_database_server.sh

4. Install the Derby database service:

   sudo ./install_database_service.sh

5. Run one of the following commands to start the Derby service:

   sudo systemctl start connect-database

   sudo systemctl enable connect-database

6. Prepare the database. Run the prepare_database.sh script:

   ./prepare_database.sh

7. Using the sudo user, deploy the Micro Focus Connect service:

   sudo ./install_service.sh

8. Start the Micro Focus Connect service with one of the following commands:

   sudo systemctl start connect

   sudo systemctl enable connect

9. To verify the installation, check the service's status:

   sudo systemctl status connect

   Wait for the system to return an Active status.

10. Secure the database. For details, see Install SSL certificates.

11. Using the URL, for example, http://my_server:8081/ConnectWeb/index.html and the credentials provided to you, log into Micro Focus Connect.

## Perform a server node installation - Linux

For multi-node installations, you install Micro Focus Connect server nodes on multiple Linux machines, accessing an existing database. Before installing a server node, make sure that you have a database installed through a standalone database installation. For details, see Perform a full Linux installation.

To install a Micro Focus Connect server node:

1. Navigate to the deployment directory:

   cd MicroFocusConnect

2. Prepare the database:

   1. Edit the connect_database.env file and change the default host value to the name of the database machine. Do not keep the default value, localhost.

   2. Run the prepare_database.sh script.

      ./prepare_database.sh

3. Remove extraneous example folders. The content of these folders may interfere with Micro Focus Connect.

   1. Stop the tomcat server.

      sudo systemctl stop connect

   2. Delete the webserver\webapps\examples folder and if present, the webserver\work\Catalina\localhost\examples folder.

   3. Restart the tomcat server.

      sudo systemctl start connect

4. Using the sudo user, deploy the Micro Focus Connect service:

   sudo ./install_service.sh

5. Start the Micro Focus Connect service with one of the following commands:

   sudo systemctl start connect

   sudo systemctl enable connect

6. To verify the installation, check the service's status:

   sudo systemctl status connect

   Wait for the system to return an Active status.

7. Using the URL, for example, http://my_server:8081/ConnectWeb/index.html and the credentials provided to you, log into Micro Focus Connect.

8. Open the Servers tab to view a list of the Micro Focus Connect server nodes.
