Use this script to deploy nfdump Agent on multiple Hosts

Prerequisites:

The InsightFinder nfdump agent requires internet access to download the packages needed for the installation process. After installation is complete, any proxy should be disabled to allow our agents to send data using the correct port. Ensure that your /tmp directory has at least 50MB of disk space available because the apt/yum package managers use /tmp as scratch space for package installation (e.g., package inflation).

SSH accesses to all hosts where agents will be installed are required. SSH key can be generated by following this link: https://www.ssh.com/ssh/keygen/

Tested with ansible version 2.2.3.0

Install wget to download the required files :

For Debian and Ubuntu

sudo -E apt-get update
sudo -E apt-get install wget

For Fedora and RHEL-derivatives

sudo -E yum update
sudo -E yum install wget

Note: If you are using proxy, the proxy needs to be set for both the current user and root

Get copy of the deployment script:

  1. Use the following command to download the insightfinder agent code.
wget --no-check-certificate https://github.com/insightfinder/InsightAgent/archive/master.tar.gz -O insightagent.tar.gz
or
wget --no-check-certificate http://github.com/insightfinder/InsightAgent/archive/master.tar.gz -O insightagent.tar.gz

Untar using this command.

tar -xvf insightagent.tar.gz

cd InsightAgent-master/deployment/DeployAgent/
sudo -E ./installAnsible.sh
  1. Open and modify the inventory file
[nodes]

###We can specify the host name with ssh details like this for each host
##If you have the ssh key
#192.168.33.10 ansible_user=vagrant ansible_ssh_private_key_file=/home/private_key

##If you have the password
#192.168.33.20 ansible_user=vagrant ansible_ssh_pass=ssh_password


##We can also specify the host names here and the ssh details under [nodes:vars] if they have have the same ssh credentials
##(Only one of ansible_ssh_pass OR ansible_ssh_private_key_file is required)
#192.168.33.10
#192.168.33.15
