Interactive Installation on Linux

The Linux typical install is an interactive script that asks you a series of questions during the installation. You can also install CTE using a silent installer which pre-packages the install information. This allows you to install CTE on a large number of hosts. (For more information, see Silent Installation on Linux.

After you install CTE, you are prompted to register it immediately with a key manager. CTE must be registered with a key manager before you can protect any of the devices on the host. However, you may postpone the registration if you plan to register CTE later.

Prerequisites

The following prerequisites must be met for CTE/CTE-U to install and register to CipherTrust Manager properly:

• CipherTrust Manager installed and configured. See CipherTrust Manager Documentation for more information.

• CipherTrust Manager must contain a Client Profile. See Changing the Profile for more information.

• CipherTrust Manager must contain a registration token. See Creating a Registration Token.

• Optionally, the name of the host group you want this client to be a part of.

• CipherTrust Manager must contain an LDT Communication Group if you will use CTE to guard data over CIFS/NFS shares using LDT policies. See Managing LDT Communication Groupsfor more information.

Procedure

1. Log on to the host where you will install the CTE Agent as root. You cannot install the CTE Agent without root access.

2. Copy or mount the installation file to the host system. If necessary, make the file executable with the chmod command.

3. Install the CTE Agent. A typical installation uses the following syntax:

   ./vee-fs-<release>-<build>-<system>.bin
   

   For example:

    ./vee-fs-7.3.0-135-rh8-x86_64.bin
   

   To install the CTE Agent in a custom directory, use the -d <custom-dir> option. For example:

    ./vee-fs-7.3.0-135-rh8-x86_64.bin -d /home/my-cte-dir/
   

   Note

   If possible, Thales recommends that you use the default directory /opt/vormetric.

   To view all installer options, use the -h parameter. For example:

    ./vee-fs-7.3.0-135-rh8-x86_64.bin -h
   

4. The Thales License Agreement displays. When prompted, type Y and press Enter to accept.

   The install script installs the CTE Agent software in either /opt/vormetric or your custom installation directory and then prompts you about registering the CTE Agent with a key manager.

   Welcome to the CipherTrust Transparent Encryption File System Agent Registration Program.

    Agent Type: CipherTrust Transparent Encryption File System Agent
    Agent Version: <Release.build-number>
   
    In order to register with a CipherTrust Manager you need a valid registration token from the CM.
   
    Do you want to continue with agent registration? (Y/N) [Y]:
   

5. Type N and press Enter to end the installation procedure without registering the CTE Agent with a key manager.

6. Enter Y to continue with the registration process. The install script prompts you to enter the host name or IP address of the CipherTrust Manager with which you want to register CTE. For example:

   CTE for CipherTrust Manager

   Do you want to continue with agent registration? (Y/N) [Y]: Y
   
   Please enter the primary key manager host name: 10.3.200.141
   
   You entered the host name 10.3.200.141
   
   Is this host name correct? (Y/N) [Y]: Y
   

   CTE for CDSPaaS

   Do you want to continue with agent registration? (Y/N) [Y]: Y
   
   Enter the primary key manager host name of the service:
   
   You entered the host name us1.ciphertrust.dpondemand.i
   
   Is this host name correct? (Y/N) [Y]: Y
   

   Host names:

   • Europe: ciphertrust.dpondemand.io

   • North America: us1.ciphertrust.dpondemand.i

   Note

   The default communication port is 443. If you want to specify a different communication port, enter it with the primary key manager host name in the format: <hostName>:<port#>

7. Enter the client host name when prompted.

   Please enter the host name of this machine, or select from the following list.
   
   [1] sys31186.qa.com
   [2] 10.3.31.186
   
   Enter a number, or type a different host name or IP address in manually:
   What is the name of this machine? [1]: 2
   You selected "10.3.31.186".
   

8. Enter the CipherTrust Manager registration token, profile name, host group and host description. If you omit the profile name, CipherTrust Manager associates the default client profile with this client.

   Please enter the registration token: 12345
   Please enter the profile name for this host: My-Profile
   Please enter the host group name for this host, if any:
   Please enter a description for this host: RHEL7 system West Coast Datacenter
   
   Token            : 12345
   Profile name     : My-Profile
   Host Group       : (none)
   Host description : RHEL7 system West Coast Datacenter
   Are the above values correct?  (Y/N) [Y]: Y
   

9. At the hardware association prompt, select whether you want to enable the hardware association feature to prevent cloning. The default is Y (enabled):

   It is possible to associate this installation with the hardware of this machine. If selected, the agent will not contact the key manager or use any cryptographic keys if any of this machine's hardware is changed. This can be rectified by running this registration program again. Do you want to enable this functionality? (Y/N) [Y]: Y

10. At the LDT prompt, specify that you want this client to use CTE-LDT by typing Y and pressing Enter:

    Do you want this host to have LDT support enabled on the server? (Y/N) [N]: Y
    

11. If you are planning to create GuardPoints on NFS shares, enter the name of the LDT Communication Group that this node will join.

    Enter the LDT Communication Group name: LCG1
    

    Warning

    The registration token, profile name, client group name and LDT Communication Group name are case-sensitive. If any of these are entered incorrectly, the client registration will not succeed. If the registration fails, click Back in the installer and verify that the case is correct for all entries on this page.

12. At the Cloud Object Storage (COS) prompt, specify whether you want this client to use CTE COS.

    Do you want to configure this host for Cloud Object Storage? (Y/N) [N]:
    

13. CTE finishes the installation and registration process.

    Generating key pair for the kernel component...done.
    Extracting SECFS key
    Generating EC certificate signing request for the vmd...done.
    Signing certificate...done.
    Enrolling agent with service on 10.3.200.141...done.
    Successfully registered the CipherTrust Transparent Encryption CTE Agent with the CipherTrust Manager on 10.3.200.141.
    
    Installation success.
    

14. In CipherTrust Manager, change the client password using the manual password creation method. This password allows users to access encrypted data if the client is ever disconnected from the CipherTrust Manager. For details on changing the password, see the CipherTrust Manager documentation.
