Linux installation

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

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

In this topic:

Installation types

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

• Standalone (single-node) installation. This option performs a full standalone installation of the Connect service and the database service on same machine. This type of installation does not allow other machines to access the database.

• Multi-node installation. This option allows you to install Connect on multiple machines, all accessing the same database.

Before you install Connect

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

1. Check the Support Matrix to make sure that your environment is supported.
2. Download 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.

Perform a full Linux installation

This section describes how to perform a full standalone installation of Connect on a Linux machine.

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 <MFConnect_installdir>/Database/bin folder.

   2. Open the 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 Connect service:

   sudo ./install_service.sh

8. Start the 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 Connect.

Perform a server node installation - Linux

For multi-node installations, you install 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 server node:

1. Go 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 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 Connect service:

   sudo ./install_service.sh

5. Start the 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 Connect.

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

Install as a standalone application

You can install Connect as an application only, and not as a service that runs continuously in the background.

This option is useful if you are trying out Connect.

Run the following commands:

Stop and uninstall Connect

Use the following commands to stop or uninstall Connect:

Action	Command
Stop the Connect service	sudo systemctl stop connect
Start the Connect service after system boot	systemctl enable connect
Start the Connect service	systemctl start connect
Do not start the service automatically after system boot	systemctl disable connect
Uninstall Connect	sudo ./uninstall_service.sh
Remove the Connect files	rm -rf MicroFocusConnect/

Increase maximum allocated memory in Linux

The following procedure describes how to increase maximum allocated memory for Tomcat on Linux deployments.

To increase the maximum allocated memory:

1. Locate the file setenv.sh in the /MicroFocusConnect/WebServer/bin directory.
2. Open the file and modify the value for -Xmx in JAVA_OPTS parameters.
3. Restart the Connect service.
