Enter fullscreen mode Exit fullscreen mode

Install required packages

sudo apt install wget jq git build-essential pkg-config libssl-dev -y
Enter fullscreen mode Exit fullscreen mode

Instal Rust

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/installers/rust.sh)
Enter fullscreen mode Exit fullscreen mode

Rust version must be at least1.65.0

rustc --version

-un
Enter fullscreen mode Exit fullscreen mode

Clone the repository with the node

cd; git clone https://github.com/AleoHQ/snarkOS.git --depth 1
Enter fullscreen mode Exit fullscreen mode

Go to the folder with snarkOS

cd snarkOS
Enter fullscreen mode Exit fullscreen mode

Build the snarkOS binary

cargo build --release
Enter fullscreen mode Exit fullscreen mode

Copy the binary file to the standard binary storage

mv $HOME/snarkOS/target/release/snarkos /usr/bin
Enter fullscreen mode Exit fullscreen mode

Already have a wallet

Place a file called aleo_account.txt, necessarily containing the string

      Private key  APrivateKey1___
Enter fullscreen mode Exit fullscreen mode

On the path (the command displays the path)

echo $HOME/aleo_account.txt
Enter fullscreen mode Exit fullscreen mode

No wallet yet

Create a wallet

snarkos account new > $HOME/aleo_account.txt
Enter fullscreen mode Exit fullscreen mode

Make a backup copy of the wallet data file, saving it in a safe place (the command displays the path)

echo $HOME/aleo_account.txt
Enter fullscreen mode Exit fullscreen mode

Do not show private key to anyone

Continuation

Add the wallet address to the system as a variable

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/insert_variable.sh) -n aleo_wallet_address -v `grep -oPm1 "(?<=Address  )([^%]+)(?=$)" $HOME/aleo_account.txt`
Enter fullscreen mode Exit fullscreen mode

Add the private key of the wallet to the system as a variable

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/insert_variable.sh) -n aleo_private_key -v `grep -oPm1 "(?<=Private Key  )([^%]+)(?=$)" $HOME/aleo_account.txt`
Enter fullscreen mode Exit fullscreen mode

Check adding variables to the system

echo $aleo_wallet_address $aleo_private_key
Enter fullscreen mode Exit fullscreen mode

If one of them is missing, then they will return to the step with working with the wallet .

Open used ports

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/ports_opening.sh) 3033 4133

Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target" > /etc/systemd/system/aleod.service
Enter fullscreen mode Exit fullscreen mode

sudo systemctl daemon-reload
sudo systemctl enable aleod
sudo systemctl restart aleod

Add a command to view the node log to the system as a variable

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/insert_variable.sh) -n aleo_log -v "sudo journalctl -fn 100 -u aleod" -a
