Part 4: Specify the script commands

The steps below describe the process of specifying the commands to download and run the installers on the remote hosts and to run the installed Agent Manager instances.

1
Add the lines below after those that you added in Part 3: Add the script parameters . These lines verify the existence of the hostnames file and then process it.
############################################################
# Check that the HOSTFILE exists.
if [ -r $HOSTFILE ]; then
# Start the For loop to process each host in the HOSTFILE.
for i in $(cat $HOSTFILE);
do
# Parse the HOSTFILE to get the host name and then the
# installer type.
HOSTNAME=`echo $i | awk -F , '{print $1}'`
OSTYPE=`echo $i | awk -F , '{print $2}'`
if [ $FMS_VER -ge 550 ]; then
FMS_VER_MAJOR=`echo $FMS_VER | cut -c1`
FMS_VER_MINOR=`echo $FMS_VER | cut -c2`
FMS_VER_MICRO=`echo $FMS_VER | cut -c3`
INSTALLER_PREFIX=fglam-\
${FMS_VER_MAJOR}_${FMS_VER_MINOR}_${FMS_VER_MICRO}-
else
INSTALLER_PREFIX=fglam-
fi
# Match the operating system to the installer.

;;
*)
echo "Cannot match the operating system type ($OSTYPE) for \
$HOSTNAME, skipping the deployment of the Agent \
Manager to that host."
continue;
;;
esac
2
Add the lines below to the end of the file. These lines run the ssh command that:
•
Retrieves the installers using Wget.
•
Uses the silent installer to install the Agent Manager on each remote UNIX host specified in the hostnames file. The Agent Manager silent installer is invoked in this example with the command /tmp/${INSTALLER} --silent --fms url=${FMS} --installdir ${INSTALL_DIR}.
•
Runs the Agent Manager on the specified hosts.
############################################################
# Run the SSH command to install the Agent Manager.
ssh $FGLAM_USER@$HOSTNAME "cd /tmp; wget -q \
--tries=10 \"${FMS}${FMS_INSTALLERS}${INSTALLER}\" \
-O ${INSTALLER}; chmod a+x /tmp/${INSTALLER}; \
/tmp/${INSTALLER} --silent --fms url=${FMS} --installdir \
${INSTALL_DIR}; sleep 3; ${INSTALL_DIR}/bin/fglam \
--daemon; sleep 3; rm /tmp/${INSTALLER};"
echo "Installation complete on $HOSTNAME."
echo "Connect to $HOSTNAME and use tail -f \
${INSTALL_DIR}/state/default/logs/FglAM*.log to validate \
the installation."
done
else
echo "$HOSTFILE does not exist, exiting..."
exit 1
fi
exit 0
3
Save remote_install_fglam_example.sh.

Part 5: Run the script

Once you have finished editing the deployment script, it is ready to run to deploy the Agent Manager to the remote UNIX hosts.

 
* 
NOTE: This part of the example 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, then you might encounter one of the following scenarios when establishing an SSH connection:
•
You do not need to provide a password because the host to which you are connecting is a trusted host.
•
You are prompted for a passphrase instead of a password.
1
Ensure that remote_install_fglam_example.sh is executable.
2
Execute the remote_install_fglam_example.sh script.
If Wget is not found on a host or if the operating system listed for a host in the hostnames file does not match the operating system types listed in the script, the script continues deploying the Agent Manager to the rest of the hosts that you specified in the hostnames file.
3
Provide a password for each host when you are prompted to do so.
The Agent Manager is installed and running on the specified hosts.

Example: Deploying the Agent Manager to multiple Windows hosts

The recommended method of deploying the Agent Manager to a large number of Windows hosts is to use a software deployment tool such as Microsoft® Systems Management Center.

Example: Using a software deployment tool and silent installer parameters

The example in this section outlines a scenario in which you use a software deployment tool and provide it with Agent Manager silent installer parameters to install the Agent Manager on multiple Windows hosts.

 
* 
CAUTION: Using a deployment tool and Agent Manager silent installer parameters is an advanced activity. You should do so 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, run the interactive GUI or command-line installer on each machine instead.
