Test you can ping by name from a host: ping mongodb-1gb-nyc2-02 # The following lines are desirable for IPv6 capable hosts Our entire /etc/hosts file example for mongodb-1gb-nyc2-01: 127.0.1.1 mongodb-1gb-nyc2-01 mongodb-1gb-nyc2-01 Review each host’s private IP: /sbin/ifconfig eth1 | grep 'inet addr:' | cut -d: -f2| cut -d' ' /sbin/ifconfig eth1 | grep 'inet addr:' | cut -d: -f2| cut -d' ' /sbin/ifconfig eth1 | grep 'inet addr:' | cut -d: -f2| cut -d' ' -f1Ĭreate hosts file entry for each site and then enter it into each server’s /etc/hosts/ file: 10.128.32.63 mongodb-1gb-nyc2-01 SSH into your droplets and validate their hostname: hostname hostname hostname -f Your droplets will need a few post-configuration options for our automation to begin working correctly. Next, select a hostname, in this case we’ll use something able to identify where we are located and what we are doing: When creating these new droplets, it’s a good idea to enable this service. DigitalOcean has a Private Networking option, making it easy to configure your deployment securely. Cloud Manager supports many different OSs and has a number of agents available. First ensure you’ve got credit and the appropriate ssh key you plan on working imported to your account.įirst I’ve created the three droplets required, I am using Ubuntu 14.04 LTS 圆4, however feel free whichever of the supported versions we have agents for. I think today I will start by working on a simple three node replica set using 1GB sized droplets. Let’s begin by determining what our use case and requirements are for our application. Please review our documentation on configuring MongoDB with iptables on Linux. This post is how you can get started using automation on your droplets.Ī note: This does not provide details on configuring security for your system. Cloud Manager automation is an easy way to create new MongoDB deployments without having to do much of the underlying configuration work.
