[TESTNET-5] Installation guide

Setting up a new user

First we need to login as root.

ssh root@SERVER_IP

image

Adding user kira to our instance.

adduser --disabled-password kira

image

Making user kira sudoers user.

usermod kira -aG sudo

image

Managing access for user

I suggest proceeding with key access to the user. You need to generate key pairs. If you don't feel like you can proceed furthe -skip it. Proceed to [Kira Manager Installation]

[LINUX like systems]

On your workstation(not HOST/Server) create a key pair.

mkdir -p keys && cd keys && mkdir -p kira && cd kira
ssh-keygen -t rsa
#Let's name them kira_key to avoid ambiguity in future

You should choose a destination and a passphrase to continue. After keys are created you need to copy them to your host. We need to make sure that a proper directory exists. On your HOST/Server execute following commands as root:

mkdir -p /home/kira/.ssh/ && cd /home/kira/.ssh/ && touch authorized_keys

Let's set proper permissions for this directory:

chown -R kira:kira /home/kira/.ssh
chmod 700 /home/kira/.ssh
chmod 600 /home/kira/.ssh/authorized_keys

We need to edit the sshd_config file to allow PubkeyAuthentication. To do this execute:

nano /etc/ssh/sshd_config

Find this two parameters:

PubkeyAuthentication yes
PasswordAuthentication no

Uncomment if needed. Set correct values ^^ CTRL + S CTRL + X - to save changes and exit

systemctl restart sshd.service

Now we want to copy the public key from our workstation to our HOST/server. To do so we need to execute following [on workstation]:

scp /home/$USER/keys/kira/kira_key.pub root@SERVER_IP:/home/kira/.ssh/

Let's check if we successfully copy our key. Execute this commands on your HOST/Server as root user

cat /home/kira/.ssh/kira_key.pub >>/home/kira/.ssh/authorized_keys

Now we can test our setup. We will try to connect from our workstation to HOST/Server using new credentials. Following command should be executed on workstation:

ssh -i /home/$USER/keys/kira/kira_key kira@SERVER

Something similar will appear:

image

Now we settled but login to HOST/Server looks like a pain. What we can to is to configure one more file to make our lives easier.

[./ssh/config - magic helper]

On the workstation we need to edit file config.

nano /home/$USER/.ssh/config

Add this to your file

Host kira
 HostName SERVER_PIBLIC_IP
 User kira
 Port 22
 IdentityFile /home/$USER/keys/kira/kira_key

Now we can login from our workstation to Kira node (HOST/Server) as simple as:

ssh kira

[WINDOWS]

I don't have windows anywhere around. So here I will provide links and main idea. Main goal is to create a key pair. Public key should be copied on your server in /home//.ssh/authorized_keys And putty should have a link to your key while connecting to HOST/Server

Link1: "https://www.ssh.com/academy/ssh/putty/windows/puttygen"

Link2: "https://www.youtube.com/watch?v=-92wEg68SKQ"

[Kira Manager installation]

Now we are ready to install kira. Log out from every terminal and then log in as kira user.

ssh kira

Now we want to start our installation script.

sudo -s

cd /tmp && read -p "Input branch name: " BRANCH && \
wget https://raw.githubusercontent.com/KiraCore/kira/$BRANCH/workstation/init.sh -O ./i.sh && \
chmod 555 -v ./i.sh && H=$(sha256sum ./i.sh | awk '{ print $1 }') && read -p "Is '$H' a [V]alid SHA256 ?: "$'\n' -n 1 V && \
[ "${V,,}" != "v" ] && echo "INFO: Setup was cancelled by the user." || ./i.sh "$BRANCH"

Script will ask us to enter the branch first. image

Type: testnet-5 press Enter and after press V. Installation begins. Next screen will ask us if we accept TERMS and CONDITIONS.

image

Press any key to continue.

image

Here we have two options.

[Option 1. You filled the google form and passed KYC a long time ago.]

You will need to add your key to .secrets directory. Open a new terminal window. Login as kira.

sudo -s

touch /home/kira/.secrets/mnemonics.env && nano /home/kira/.secrets/mnemonics.env

Copy past your keys from backup. CTRL+S CTRL+X to save and exit the editor You are good to proceed!

[Option 2. You are a newcomer.]

Press 2. You will be prompted to choose bip39 seed words. From here you can use AUTOGENERATE function or to choose 24 words from here https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt and provide the whitespace-separated.

Here we should choose VALIDATOR MODE by pressing 2 Next step is to join network

Press J to participate in testnet-5

image

image

NB!: If your ssh port is not 22 - press 2 and enter the port you use!!!

To continue we need to press S.

image

At this point we need to choose a TRUSTED node from the given list. Please check https://testnet-rpc.kira.network/download/peers.txt Type IP address like this:

image

Next we need to choose the way of syncing with network. Preferable way is snpashot. Press A to discover the fresh snap.

image

Setup will ask us about the current block height. Press ENTER.

image

Confirm configuration of your node one more time. Press A

image

Let your Kira Manager set up seeds for you. So just press A

image

Your node will be rebooted. Connection to your host interrupted. Don't worry. Give your host 2-5 minutes to rest.

image

And we need to connect to user kira again.

ssh kira

or use Putty

On the host machine type:

sudo -s
kira

Installation will ask you if you want to continue.Press V to continue installation. From here it will take some time. So brew some coffee... image

Installation is finished. Now you can exit the kira setup. Press CTRL+C. And type

kira

Let KIRA MANAGER and your containers catch up. It may take some time. Be patient. image

FINAL. Your Kira Manager should look like this(if you are newcomer):

image

and if you recovered your keys. Press J to join validator seat. Enter your moniker and that's it.

image

[Troubleshooting]

[Reinstall node]

image

image

[++ command docker - stuck]

image

Open new session. Login as user.

sudo -s

ps -aux | grep containers-pkill* | awk '{print $2}' | xargs kill -9

[FAQ]

  1. Can we update node be re-init from t4 to t5 -No

  2. What should I do if I am out of space -Try to delete snapshots. Check the command from here https://github.com/MrLutik/KiraTools/blob/main/README.md

  3. How to check status of my node?

  • Check if you have validator container up & runnig. Check your stats inside validator container(streak, rank, produceed blocks).
