Foglight Agent Manager 5.8.5.2

Working with this Example

This example is based on using the Wget network utility to download Management Server installers, providing a specific set of configuration options with the Agent Manager silent installer command, and using passwords to log in to remote hosts over SSH.

However, you could instead create a script that works with any file-retrieval tool that downloads content using HTTP, such as cURL or a Perl script that uses the LWP::Simple interface.

Additionally, if you require non-default silent installer parameters, such as those used to connect to the Management Server through a proxy, you could edit the parameters used when invoking the Agent Manager silent installer to suit your environment. See Using Agent Manager Silent Installer Parameters for more information.

The end of the example, Part 5: Run the Script , describes using one type of login method (passwords) for connecting to remote machines using SSH. However, if you have private keys configured in your environment, you might encounter different scenarios when establishing an SSH connection, which are described in Part 5: Run the Script .

CAUTION: Using a deployment script for the Agent Manager is an advanced activity. You should create and use this type of script only if both of the following conditions apply:

•

You are a Foglight™ administrator who is familiar with configuring the Agent Manager

•

You are certain of the setup that is required for your environment.


	NOTE: If you are not certain which installation options you need, use the Agent Manager Installation and Configuration or command-line installer on each machine, instead.

Before You Begin

This example deployment script is designed to use a specific set of tools and protocols and depends on certain settings being configured in your environment.

If you decide to follow this example to create your own deployment script, you need to perform certain steps before you begin:

•

Enable SSH on the hosts to which you want to deploy the Agent Manager. The example describes a script that uses the ssh command.

•

Install the file retrieval tool Wget on all machines to which you want to deploy the Agent Manager. The example describes a script that uses the wget command to retrieve the Agent Manager installers from the Management Server.

See http://www.gnu.org/software/wget/ for more information about Wget.

•

Ensure that the remote hosts to which you are deploying the Agent Manager have enough space in the /tmp directory for the installer to be downloaded to that location.

Remember that you do not need to follow all parts of the example as described. For example, if you create a script, you might choose to use cURL instead of Wget to retrieve the Agent Manager installers.

Example: Creating and Running an Agent Manager Deployment Script

This section outlines the creation and use of an example deployment script and contains suggestions for customizing this type of script to suit your environment.

If you create your own script by following this example, you can use it to install and run the Agent Manager on the hosts you specify.


	CAUTION: Line breaks are added to the commands in the example script below. These are highlighted by backslashes (\) at the end of each broken line. If you copy and paste from this example to create your own deployment script, ensure that you remove these backslashes and the subsequent line break.

Part 1: Create the Working Directory and Script File

On the machine from which you deploy the Agent Manager to the remote hosts, create a working directory and create the script file within it using a text editor such as vi.

In this example, the working directory is fglaminstall and the script file is remote_install_fglam_example.sh.
