Install the Agent

Use this procedure to install an agent on Red Hat Linux, SuSe Linux, and VMware ESX Server systems. Before you begin, gather the following information:

• Host name of the CA Enterprise Log Manager server to which the agent is to return events
• Agent authentication key that is configured in the CA Enterprise Log Manager server

  Note: The agent authentication key is called the authentication code in the installation wizard.

• The root credentials on the target agent host server
• The agent installation tar file location on the host server
• (Optional) An exported connector file

To install a Linux agent

1. Log in as root on the computer on which you want to install the agent.
2. Access a command prompt and navigate to the directory where you saved the agent tar file.
3. Extract the tar file with the following command.

   For Red Hat Enterprise Linux 4.x:

   tar -xvf elm_agent_linux_k24_32_x_x_x_x.tar
   

   For Red Hat Enterprise Linux 5.x:

   tar -xvf elm_agent_linux_k26_32_x_x_x_x.tar
   

   For VMware ESX Server 3.x:

   tar -xvf elm_agent_linux_k24_32_x_x_x_x.tar
   

   For SuSe Linux 11.x:

   tar -xvf elm_agent_linux_k26_32_x_x_x_x.tar
   

4. Run the installation script, sh install_ca-elmagent.
5. Press Enter, read the end user license agreement, indicate your acceptance of the terms to continue by entering Yes, and press Enter.
6. Enter the IP address or host name for the CA Enterprise Log Manager server to which this agent forwards the log it collects, and then enter the authentication code.
7. Enter the IP address or host name for the CA Enterprise Log Manager to which this agent forwards the logs it collects, and then enter the authentication key.

   Important! Enter the host name if the CA Enterprise Log Manager is assigned its IP address dynamically.

8. Enter the authorized user credentials for the Agent user credential information and press Enter.
9. Enter yes or no to choose whether to install in FIPS mode, and press Enter.

   The agent FIPS mode you choose should match the FIPS mode for the CA Enterprise Log Manager server which manages it. However, the agent automatically detects the server FIPS mode and restarts itself as needed regardless of the mode you choose.

10. Accept the default installation path, or change it, and click Next.
11. (Optional) If you want to configure default connectors, enter yes and press Enter. Type the path and file name for the connector configuration and press Enter.

    The agent installation process completes.
