1.Prepare a Linux server. See System Requirements for more details.

2.Log in to the Linux server where MongoDB is installed as the root user.

3.Run the cd /opt/netbraintemp10.0a command to navigate to the /opt/netbraintemp10.0a directory.

4.Download the installation package.

▪Option 1: If the Linux server has no access to the Internet, obtain the netbrain-licenseagent-linux-x86_64-rhel-10.0a.tar.gz file from NetBrain and then upload it to the /opt/netbraintemp10.0a directory by using a file transfer tool.

▪Option 2: If the Linux server has access to the Internet, run the
wget <download link>command under the /opt/netbraintemp10.0a directory to directly download the file from NetBrain official download site.

Note: Contact NetBrain Support Team to get the download link. The download link is case-sensitive.

Tip: Run the yum -y install wget command to install the wget command if it has not been installed on the server.

6.Run the tar -zxvf netbrain-licenseagent-linux-x86_64-rhel-10.0a.tar.gz command under the /opt/netbraintemp10.0a directory to extract installation files.

[root@localhost netbraintemp10.0a]# tar -zxvf netbrain-licenseagent-linux-x86_64-rhel-10.0a.tar.gz
License/
License/include/
License/include/yaml.sh
License/include/yq
...
License/install.sh
...

7. Run the cd License/config command to navigate to the config directory.

8. Modify the parameters in the setup.conf file located under the config directory according to your environment and save the changes. For how to modify the configuration file, refer to Editing a File with VI Editor.

[root@localhost config]# vi setup.conf
# The IP address of the License Agent Server.
BindIp=0.0.0.0
# The port number that the License Agent Server listens to. It should be more than 1025 and less than 32767. By default, it is 27654.
Port=27654
# Specify whether to use SSL to encrypt the connections to the License Agent Server.
# By default, it is disabled. no indicates disabled; yes indicates enabled.
UseSSL=no
# If SSL is enabled, you must enter the full path of the server certificate and key file.
Certificate=/etc/ssl/cert.pem
PrivateKey=/etc/ssl/key.pem
# LogPath is used to store log files for the service of netbrainlicense.
# This directory must be at least a second level directory and used exclusively for this purpose.
LogPath=/var/log/netbrain/netbrainlicense

9. Run the cd .. command to navigate to the License directory.

10. Run the ./install.sh script under the License directory to install License Agent.

1)Read the license agreement, and then type YES and press the Enter key.

2)Type I ACCEPT and press the Enter key to accept the license agreement. The script starts to check whether the system configuration of the Linux server meets the requirement, and all required dependent packages are installed for each Linux component.

[root@localhost License]# ./install.sh
