Anyways, we just want to set up our first fabric sample asap so just do the following: Now for installing fabric samples and binaries, they provide a simple script to make your life easy also make the process obfuscated so that we need to put some extra effort to understand what is going on underneath. Go version # ckeck if it is installed correctly sudo apt-get install nodejs we need to install some prerequisites: curl, git, docker, docker-compose, golang, nodejs, npm sudo apt-get install curlĭocker -version # just to ckeck if it is installed correctly sudo usermod -a -G docker $USER sudo systemctl start dockerĭocker-compose -version # ckeck if it is installed correctly sudo apt-get install golang Elasticsearch listens on that port for incoming requests.Ĭreate the rule with this command: sudo ufw allow from external_IP to any port 9200Ĭhange external_IP with the IP of the remote machine that will be used to access Elasticsearch.In this post I will give you clear steps that you can follow to get started with Hyperledger Fabric quickly in Ubuntu 18.04.

Then, you need to allow access on port 9200 for your remote machine. In the terminal, type in: sudo ufw allow 22 For remote access over SSH, you need to allow access on port 22 (or the custom port if you changed the default SSH configuration). Enable UFW and create a few rules to limit the exposure of your network.īefore enabling UFW, add the necessary rules. The Uncomplicated Firewall (UFW) is built into Linux and disabled by default. If you allow remote access to Elasticsearch, then we strongly advise using the UFW tool, as a minimum security measure. Use UFW to Secure Elasticsearch (Optional) If you only set network.host to 0.0.0.0, you may be unable to restart the Elasticsearch service after this change.

Note: Make sure to add all the lines we listed above.
