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

2.Log in to the Linux server as the root user.

Note: If a MongoDB replica set has been deployed, you must install the License Agent Server on both primary and secondary nodes.

3.Obtain the netbrain-license-linux-x86_64-rhel7-7.1a2.tar.gz file from NetBrain, and then copy it to the /opt/netbraintemp directory.

▪Option 1: If the Linux server has no access to the Internet, upload the netbrain-license-linux-x86_64-rhel7-7.1a2.tar.gz file to the /opt/netbraintemp directory by using a file transfer tool.

▪Option 2: If the Linux server has access to the Internet and the yum command has been installed:

1)Run the yum -y install wget command to install the wget command if it has not been installed.

2)Run the cd /opt/netbraintemp command to navigate to the /opt/netbraintemp directory.

3)Run the wget <NetBrain IE 7.1a NetBrain License download link> command under the /opt/netbraintemp directory to directly download the netbrain-license-linux-x86_64-rhel7-7.1a2.tar.gz file to this directory.

Tip: Contact NetBrain Support Team to get the download link address.

Note: The download link is case-sensitive.

5.Run the tar -zxvf netbrain-license-linux-x86_64-rhel7-7.1a2.tar.gz command under the /opt/netbraintemp directory to extract installation files.

[root@localhost netbraintemp]# tar -zxvf netbrain-license-linux-x86_64-rhel7-7.1a2.tar.gz

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

7.Modify the parameters in the install_licenseagent.conf file located under the License directory according to your environment and save the changes. For how to modify the configuration file, see Appendix: Editing a File with VI Editor for more details.
