(I am working with CentOS 7)

Requirements:

• unzip
• wget

Installing Packer

Move to /usr/local/bin, download and unpack packer.

cd /usr/local/bin/
wget https://releases.hashicorp.com/packer/1.2.5/packer_1.2.5_linux_amd64.zip
unzip packer_1.2.5_linux_amd64.zip
rm -f packer_1.2.5_linux_amd64.zip
cd
packer --version

Now you can start creating a template.
