First mononode Stake Pool using CNTools

Andrea_Ferrarini · 21 March 2021 09:49

Hello,
I’m trying to configure my first stake pool using cntools and i want to configure a mononode with Producer and Relay.

I have a cloud instance machine with this configuration:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet MYPUBLICIP netmask 255.255.240.0 broadcast MYBROADCAST
…

eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.110.0.2 netmask 255.255.240.0 broadcast 10.110.15.255
…

netstat -an | grep -i list
tcp 0 0 127.0.0.1:12788 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:2517 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:12798 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN
tcp6 0 0 :::2517 :::* LISTEN

I put in “env” file “CNODE_PORT=6001”
I have to edit “topologyUpdater.sh” for relay:
CUSTOM_PEER = “producer ip:port|relays-new.cardano-mainnet.iohk.io:3001:2”

what ip and port should i put in?

I have to edit topology.json for Producer, so I put:

{
“Producers”: [
{
“addr”: “MYPUBLICIP”,
“port”: 6001,
“valency”: 1
},

Is that right or better to use internal or 127.0.0.1 IP?

I have to run ./deploy-as-systemd.sh that is configuring for me cnode.service

should I put “YES” to topology updater? this is needed for relays and i want to run both in a single machine… should I make a difference between processes configuring 2 separate services? What do you think?

Thank you very much!!!

Hi There!

I am not familiar with cntools - what is the listen port of your producer node? if the default one, which is 3001 then the CUSTOM_PEER should be this:

CUSTOM_PEER="127.0.0.1:3001|relays-new.cardano-mainnet.iohk.io:3001:2"

yes, you can use 127.0.0.1 as MYPUBLICIP in the producer toplogy file, since the relay node listens on all interfaces - tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 0.0.0.0 means that listens on all interfaces, like on the loopback interface.
yes, use YES for the topology updater

Hi, thank you very much for your answer!
I’m very confused about producer listener port:

In netstat I show you I have:

tcp 0 0 127.0.0.1:12788 0.0.0.0:* LISTEN -----> ???
tcp 0 0 0.0.0.0:2517 0.0.0.0:* LISTEN ---------- SERVICE I KNOW, SERVER USED PORT
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN -----------> Maybe a DNS I dont KNOW
tcp 0 0 127.0.0.1:12798 0.0.0.0:* LISTEN -----------> ???
tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN ---------------> PORT I put in “env” file “CNODE_PORT=6001” (RELAY ???)
tcp6 0 0 :::2517 :::* LISTEN -------------------> SERVICE I KNOW, SERVER USED PORT

IF I ask for the service status I get:

sudo systemctl status cnode.service
● cnode.service - Cardano Node

Mar 21 10:24:12 iscsp-node01 cnode[236645]: Listening on http://127.0.0.1:12798

So 12798 should be Producer port?
Where can I find this value?

And another question: how I can verify if Relay is connecting regularly with producer and if all is working properly?

Thank you very much for your answers! They are gold for me!

use sudo netstat -noptla to get the process name, I think producer not started yet…

Andrea_Ferrarini · 21 March 2021 15:36

That’s the output:

sudo netstat -noptla | grep -i list
tcp 0 0 127.0.0.1:12788 0.0.0.0:* LISTEN 240443/cardano-node off (0.00/0/0)

Thank you very much!

Hei!

those are monitoring ports - prometheus and EKG… these port definitions can be found in /opt/cardano/cnode/files/config.json
So the producer not started yet - how did you started the producer pool? do you have all the keys certs generated for producer node?
so you need separate services for each node - is there any option to generate the service file for the producer node?

Alexd1985 · 21 March 2021 15:46

U have a script called gLiveView.sh inside scripts folder

U can run it and u should see peers 1/1 (if u have only one relay) …more if u press p u will see more details like IP and port of the remote peer

Cheers,

Andrea_Ferrarini · 21 March 2021 15:51

Hi,
I followed this istructions and I read that, also if not best pratice, I can configure Producer and Relay on the same server:

Creating non-root user:

sudo adduser node
sudo adduser node sudo
sudo su - node
mkdir ~/.ssh
cd .ssh
nano ~/.ssh/authorized_keys

disable root login/Set new SSH Port:

sudo nano /etc/ssh/sshd_config
sudo systemctl restart ssh
sudo systemctl status ssh

Update Ubuntu:

sudo apt-get update
sudo apt-get upgrade

Creating firewall:

relay nodes:

ufw default deny incoming
ufw default allow outgoing
ufw limit proto tcp from any to any port [custom ssh port]
ufw allow [relay port]/tcp

producer node:

ufw default deny incoming
ufw default allow outgoing
ufw limit proto tcp from any to any port [custom ssh port]
sudo ufw allow from [relay 1 ip] to any port [producer port] proto tcp
sudo ufw allow from [relay 2 ip] to any port [producer port] proto tcp

Installing Prereqs:

mkdir “$HOME/tmp”
cd “HOME/tmp" curl -sS -o prereqs.sh https://raw.githubusercontent.com/cardano-community/guild-operators/master/scripts/cnode-helper-scripts/prereqs.sh chmod 755 prereqs.sh ./prereqs.sh -f . "{HOME}/.bashrc”

Installing cardano-node and cardano-cli:

cd ~/git
git clone GitHub - input-output-hk/cardano-node: The core component that is used to participate in a Cardano decentralised blockchain.
cd cardano-node
git fetch --tags --all
git pull
git checkout $(curl -s https://api.github.com/repos/input-output-hk/cardano-node/releases/latest | jq -r .tag_name)
$CNODE_HOME/scripts/cabal-build-all.sh -o
[cardano-cli version]
[cardano-node version]

configuring env and starting node:

cd $CNODE_HOME/scripts
nano env
CNODE_PORT=[PORT]
POOL_NAME=[NAME]

./deploy-as-systemd.sh
sudo systemctl start cnode.service
sudo systemctl status cnode.service
./sLiveView

Editing topologyUpdater.sh for relays:

CUSTOM_PEER = “producer ip:port|relays-new.cardano-mainnet.iohk.io:3001:2”
sudo systemctl restart cnode.service

Editing topology.json for Producer:

{
“Producers”: [
{
“addr”: “relay ip”,
“port”: relay port,
“valency”: 1
},
{
“addr”: “other relay ip”,
“port”: other relay port,
“valency”: 1
}
]
}

Creating wallet/Registering pool:

./cntools.sh

Andrea_Ferrarini · 21 March 2021 15:54

The problem is that i would like run relay and producer on the same server

Alexd1985 · 21 March 2021 15:56

Ok, understand… but u have 2 users created on server, one for relay and one for producer?

Cheers,

laplasz · 21 March 2021 16:00

./deploy-as-systemd.sh - this script starts only 1 node. do you have a link to the instructions you followed?

Andrea_Ferrarini · 21 March 2021 16:00

No, by now I have only one user maybe I have to use 2 different users… do you suggest it to me?

Alexd1985 · 21 March 2021 16:00

I think he installed everything for a single node… but now he want to start 2 nodes… which should be done in 2 separate intances of linux

Andrea_Ferrarini · 21 March 2021 16:02

Exactly it’s what I have done

laplasz · 21 March 2021 16:03

yes - so what is needed here a new folder for producer node and use cntools.sh inside that folder to get a new configs of producer node?

Alexd1985 · 21 March 2021 16:06

CNTOOLS is just a fancy application for signining transactions ( it has a friendly gui )… not for generating any configs

Alexd1985 · 21 March 2021 16:08

What is the hw configuration of the server? And u want to do this on your home desktop?

laplasz · 21 March 2021 16:08

ok - no need to have 2 users - just create a new CNODE_HOME folder for the producer node and start again the process - new env file, and so on for the new node…

laplasz · 21 March 2021 16:12

that is what I meant on cntools.sh

github.com

cardano-community/guild-operators/blob/alpha/scripts/cnode-helper-scripts/cntools.sh

except you dont need to build the cardano-node and cli again… I forget to mention this… so basically you will start cardano-node twice with different ports and configs - systemctl can handle this - cnode.sh script will detect what type of node is in CNODE_HOME
