Installing Hyperledger Composer on AWS Linux

问题:

I have an AWS instance running Fabric created from an AWS Fabric template. Unfortunately, this is a Linux (not Ubuntu) instance. Now I'm trying to install the composer tools on the same instance. The docs say that I shouldn't install anything as a root, but the system won't let me install Node unless I'm a root. When I'm trying to install composer-cli (w/o sudo), I get various permission errors. Is itpossible at all to install composer on a non-Ubuntu system?

Another option is to connect to the Fabric from another instance (which is based on Ubuntu). How do you do that? Is it possible? What I need is use composer-cli tools to work with the existing Fabric instance running on AWS Linux.

Regarding installing on a non-ubuntu system some users have suceeded on AWS, and on Centos so it is possible. I would work through the pre-requisites in the prereqs-ubuntu.sh script. The particular warnings are about not using sudo or root when installing npm modules, and this doc may help with that problem.

Using a separate Ubuntu system as a 'client' should work, and is actually a more realistic production scenario. You would need to make all the ports of your fabric available perhaps with firewall configuration, then on the client machine you need to create/update your connection profile (connection.json) with the addresses of the remote Fabric.
