Installing the FlexNet server

Magic Collaboration Studio can be configured to access a FlexNet server for license checkout and validation. The FlexNet server can be installed on the same system or on a separate machine.

Prerequisites

OpenJDK Java (1.8, 11.0, 17.0 or 21.0)
Linux utility package unzip (repository)
FlexNet 11.19.8 64-bit: lmadmin installer
FlexNet 11.19.8 64-bit utilities: lmgrd (zip file)
Cameo daemon for FlexNet 11.19.8 64-bit (zip file)

Installing FlexNet server

The install_flex_ol_rhel.sh script will download all required components, deploy the server, create the systemd service entry to control it, and create the necessary firewall rules to allow the required traffic (if firewalld is running). The script may require modification depending on the zone where the interface is located. In addition, the script creates the lmadmin user, which runs the lmadmin service.

The script can also be used for offline installation. Download and place the FlexNet and Cameo daemon packages in the same location as the script. The lmadmin installer can work with several versions of Java, but at least one version needs to be installed on the system in order for the installer to run.

To install the FlexNet server

Run the install_flex_ol_rhel.sh script to start the installation and follow the installer instructions.

All default values presented by the installer should be accepted, except for the installation path, which may be customized if you do not choose the silent installation.
After the lmadmin service is installed, start it by executing the following command:
```
sudo systemctl start lmadmin
```
BASH
To check if the service is running, execute the following command:
```
sudo systemctl status lmadmin
```
BASH

Troubleshooting

If the Imadmin service failed to start, it is often because the built-in web server cannot resolve the hostname.

To check if this is the case, execute the following commands:

cd <install_root>/FNPLicenseServerManager/logs
tail web.log

BASH

You will see output similar to the following, where yourhostname is the name of the host:

[Tue May 02 18:43:27] [alert] (EAI 2)Name or service not known:
mod_unique_id: unable to find IPv4 address of "yourhostname"
Configuration Failed

BASH

If this is the case, edit the /etc/hosts file and add the following entry so the web server can resolve the host:

192.168.130.10  yourhostname

BASH
