When installing the Snapt One HAProxy or Load Balancer Snaptin, you are given the option to either integrate or perform a new installation.
Should you be required to manually install the HAProxy binary, please follow the instruction below.
Depending on your operating system this may require something like
sudo apt-get install haproxy
sudo yum install haproxy
If you are using the Snapt One image it will always come pre-installed.
