# installing multiple smart nodes

### first, a few changes to make in `rocketpool s c`

In the `Execution Client` menu, Expose RPC should be set to `Open to External hosts`

In the `Consensus Client` menu, Expose API should be set to `Open to External hosts`

- Save and exit, restart the relevant docker containers.
- install to /bin/rocketpool2

wget https://github.com/rocket-pool/smartnode-install/releases/download/v1.13.0-dev/rocketpool-cli-linux-amd64 -O ~/bin/rocketpool2

- Navigate to your /bin/ folder and mark `rocketpool2` as an executable:

chmod +x /bin/rocketpool2

- adding alias to profile

sudo nano ~/.profile 

alias rp1='rocketpool -c ~/.rocketpool'
alias rp2='rocketpool2 -c ~/.rocketpool2'

- save new profile

source ~/.profile 

- install rocketpool2

rocketpool2 s i -d -p ~/.rocketpool2

To start configuring your new node, use the newly created alias and run

rp2 s c

use `ifconfig` to grab your system ip, replace your ip anywhere that says `rocketpool_eth1/2` below

You'll see the Config Wizard on your first run. Select the following options:
1. Next
2. Devnet
3. Externally Managed
4. Enter `http://rocketpool_eth1:8545` and `ws://rocketpool_eth1:8546`
5. Select the consensus client you're using for your first node. Enter `http://rocketpool_eth2:5052` (and `http://rocketpool_eth2:5053` if you're using Prysm). Choose whatever you want for Graffiti and Doppelgänger Protection.
6. If you have a working fallback setup, enter your details here.
7. No metrics.
8. Review All Settings, don't save yet!
### The next step is very important, don't miss it or stuff will break:
Select "Smartnode and TX Fees" and change the "Project Name" to `rocketpool2`. Press enter after making the change.
Select "Data Path" and change the path to `~/.rocketpool2/data`

Now you can press ESC and select "Review Changes and Save". Make sure you see `Project Name: rocketpool => rocketpool2` under "Smartnode Settings". If you do, you can save the settings and answer "yes" when asked to start the Smartnode services automatically.

# nuclear option if smartnode doesn't apply the update properly:

rp1 service stop; rp2 service stop; docker system prune -a; rp1 service start; rp2 service start;
