Compiling and installing nbdkit on CentOS 7

compile_and_install_nbdkit_centos_7.sh

#!/usr/bin/bash

# Downloads NBDKit and builds a minimal version. This minimal version only
# installs basic plugins and filters, and the SSH plugin.

# For compilation to succeed, you'll need to install
# yum install gcc gcc-c++ libssh-devel openssl-devel autoconf automake libtool

# Also, best create a user nbdkit
# adduser --system --user-group --shell /sbin/nologin --home-dir /opt/nbdkit --create-home nbdkit
