Aurora

You need a server with following requirements

8-Core (16-Thread) / 8GBRAM DDR4 / 500GB SSD

1. Upgrade your server

sudo apt update && sudo apt upgrade -y

sudo apt install make clang pkg-config libssl-dev libclang-dev build-essential git curl ntp jq llvm tmux htop screen unzip -y

2. Install docker and docker-compose

Check the latest version of docker-compose and follow the guide

sudo apt install docker.io -y

git clone https://github.com/docker/compose

cd compose
git checkout v2.6.1
make

cd
mv compose/bin/docker-compose /usr/bin
docker-compose version

3. Install and synch Aurora node

Download installation from official documentation

git clone https://github.com/aurora-is-near/partner-relayer-deploy
cd partner-relayer-deploy

For testnet purpose run

./setup.sh testnet

For mainet purpose run

./setup.sh

4. Run Aurora node through docker-compose

To run docker, you must be in the folder partner-relayer-deploy

docker-compose up -d

To see logs use command

docker-compose logs -f

5. Create SSH keys on the Aurora Node

Please run the following command on the Aurora server (just press “Enter” for each question):

cd

ssh-keygen -t ed25519

6. Add public key on the Axelar Node

Once the key pair has been generated you need to create it on the Axelar Node /root/.ssh/authorized_keys file and copy content from the /root/.ssh/id_ed25519.pub file which was created on the Aurora Node:

mkdir .ssh
nano /root/.ssh/authorized_keys

After this we need to set the following permissions:

chmod 600 /root/.ssh/authorized_keys

When you perform these actions you should be able to connect from Aurora Node to Axelar Node without password

7. Create SSH tunnel between Aurora Node and Axelar Main Node

On the Aurora server please run the following command to create a tunnel to forwarding ports:

ssh -f -N root@X.X.X.X -R 10080:`docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}:10080{{end}}' endpoint`

Please note X.X.X.X this is IP address of your Axelar Main Node

8. Check that necessary port is listening on the AxelarNode

On the Axelar Node please run the following command to make sure that port is listening:

netstat -atnp | grep 8545
tcp        0      0      127.0.0.1:10080            0.0.0.0:*               LISTEN      2306635/sshd: root
tcp6       0      0      ::1:10080                  :::*                    LISTEN      2306635/sshd: root

9. Create a script to run it automatically after reboot

Create directory

mkdir /root/work

Create tunnel.ssh file:

nano /root/work/tunnel.ssh

and add the following line into it:

ssh -f -N root@X.X.X.X -R 10080:`docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}:10080{{end}}' endpoint`

Please note X.X.X.X this is IP address of your Axelar Main Node

Then open crontab file and choose option 1:

crontab -e

and add this line to the end of it:

@reboot /root/work/tunnel.sh

so when the Aurora server will be rebooted the SSH tunnel will be created automatically

10. Connect your Aurora to Axelar

In order for Axelar Network to connect to your Aurora node, your rpc_addr should be exposed in this format:

"http://127.0.0.1:10080"
