This time i will share how to install Node for Mina Testworld 2.0, coincidentally I was also selected as a Block Producer on this testnet. Mina is a unique blockchain, its size is only 22KB and at any time, the following is Mina roadmap which will continue to be developed.

First run the following code and press ENTER:

wget -O install_mina.sh https://raw.githubusercontent.com/maragung/testnet/main/mina/install_testworld_2.0_ubuntu.sh && chmod +x ./install_mina.sh && ./install_mina.sh && rm -rf ./install_mina.sh 

Finally, if it appears like the image above, it means that Mina has been successfully installed.

Next step (Environment Variables):

To save various variables and passwords to ~/.mina-env, follow these steps (copy the password from the community-xxx-password.txt file from the email):

The following is an example of the contents of the community-xxx-password.txt file:

Run the following command to download the setup script:

wget -O setup_keys_and_password.sh https://raw.githubusercontent.com/maragung/testnet/main/mina/setup_keys_and_password.sh && chmod +x setup_keys_and_password.sh && ./setup_keys_and_password.sh && rm -rf setup_keys_and_password.sh

Once successful it will look like the following:

Next step (Keys):

Upload the files in the archive that you have received from the Mina team to the ~/keys folder, except the file community-xxx-password.txt

Change the file name community-147-key to my-wallet and community-147-key.pub to my-wallet.pub as in the following image:

Then run the following command:

sudo chmod 700 ~/keys
sudo chmod 600 ~/keys/my-wallet
ls -lh ~/keys

Then the file details will appear along with the access rights that have been applied as shown in the following image:

Next Step (Allow Mina Port):

sudo ufw allow 8302
sudo ufw allow 3089
sudo ufw allow 10001 

Next Step (Services):

Run the following command to create the unit file for the Mina service:

wget -O create_mina_service.sh https://raw.githubusercontent.com/maragung/testnet/main/mina/create_mina_service.sh && chmod +x create_mina_service.sh && ./create_mina_service.sh && rm -rf create_mina_service.sh

Starting the Service:

sudo systemctl daemon-reload
sudo systemctl enable mina
sudo systemctl start mina

Checking the Service Status:

sudo systemctl status mina

Stopping the Service:

sudo systemctl stop mina

Disabling the Service at Startup:

sudo systemctl disable mina

Removing the Service:

sudo rm /etc/systemd/system/mina.service
sudo systemctl daemon-reload

Logs:
