Build

1. Download & install Go version 1.X from https://golang.org/dl/
2. Clone this repo into $GOPATH/src/github/paxoscluster
3. Open a terminal in the paxoscluster directory and run go build

Run on local machine

This mode of operation spins up five goroutines on your local machine, each acting as an independent process running the Paxos protocol (with replica IDs 1-5) listening on ports 10000-10004. You can then type arbitrary text into the console, and upon pressing enter the text will be used as a proposed value for the next available multi-paxos slot. The replicas persist their log to disk in the coldstorage directory. All requests are sent to the proposer with ID 5, and fault injection is not supported.

To run in this mode, execute go run simplecluster.go runlocal, or after building execute PaxosCluster runlocal. Exit using ctrl+c. You can change the ports on which the processes listen by editing the coldstorage/peers.csv file.
