# Multi Node Local Testnet Script
This script creates a multi node local testnet with three validator nodes on a single machine. Note: The default weights of these validators is 5:5:4 respectively. That means in order to keep the chain running, at a minimum Validator1 and Validator2 must be running in order to keep greater than 66% power online.
## Instructions
Clone the osmosis repo
Checkout the branch you are looking to test
Make install / reload profile
Give the script permission with `chmod +x multinode-local-testnet.sh`
Run with `./multinode-local-testnet.sh` (allow ~45 seconds to run, required sleep commands due to multiple transactions)
## Logs
Validator1: `tmux a -t validator1`
Validator2: `tmux a -t validator2`
Validator3: `tmux a -t validator3`
## Directories
Validator1: `$HOME/.osmosisd/validator1`
Validator2: `$HOME/.osmosisd/validator2`
Validator3: `$HOME/.osmosisd/validator3`
## Ports
Validator1: `1317, 9090, 9091, 26658, 26657, 26656, 6060`
Validator2: `1316, 9088, 9089, 26655, 26654, 26653, 6061`
Validator3: `1315, 9086, 9087, 26652, 26651, 26650, 6062`
Ensure to include the `--home` flag or `--node` flag when using a particular node.
## Examples
Validator2: `osmosisd status --node "tcp://localhost:26654"`
Validator3: `osmosisd status --node "tcp://localhost:26651"`
or
Validator1: `osmosisd keys list --keyring-backend test --home $HOME/.osmosisd/validator1`
Validator2: `osmosisd keys list --keyring-backend test --home $HOME/.osmosisd/validator2`
