How to obtain an SSL certificate for a node

If you need an SSL certificate for your node, follow the steps below:

  1. Ensure that you use root account. It is necessary for further steps.

  2. Install acme.sh by running the following command:

    apt-get install socat
curl https://get.acme.sh | sh -s [email protected]

  3. Log out of the system.

  4. Log in again.

  5. Obtain the certificate. To do this, run the following command:

    acme.sh --issue --standalone -d your_node.example.com \
--renew-hook "cd /opt/your_node; ./stop.sh; ./start.sh"

  6. Install the certificate by running the following command:

    acme.sh --install-cert -d your_node.example.com \
--fullchain-file /opt/your_node/db/cert_your_node/your_node.example.com.crt \
--key-file /opt/your_node/db/cert_your_node/your_node.example.com.key

You can add Telegram notifications to promptly get information about Acme script actions. To do this, run:

export TELEGRAM_BOT_CHATID=“Your Telegram ID” \
export TELEGRAM_BOT_APITOKEN=“Chatbot token” \
acme.sh --set-notify --notify-hook telegram

After you've installed the certificate, you can get the certificate status by running the following command:

acme.sh --info -d your_node.example.com
