Frequently Asked Questions
Questions from the Discord Channel, email messages, and one or two we’ve thrown around internally. They’re in no particular order, but as the list grows, we’ll start looking at categorizing them into sections. Watch this space.
radix-fullnode-compose.ymlto create a `core_ledger`as an external volume.
volumes: - "./node-keystore.ks:/home/radixdlt/node-keystore.ks" - "core_ledger:/home/radixdlt/RADIXDB" (1)
1 Add this line to mount the volume and link it to the
home/radixdlt/RADIXDBfolder within the Docker instance.
Add the definition for your external volume:
volumes: nginx_secrets: core_ledger: driver: local driver_opts: o: bind type: none device: /data
/datadirectory needs to have open permissions as the user on the docker container is not available on the host. Use the following command to set permissions.
sudo chmod 647 /data
radix-fullnode-compose.yml is updated, the configuration needs to be applied. Bring down the node and then restart it using the instructions mentioned here.
docker ps command from a terminal window.
You should see separate processes for the
nginx, with both entries show their running times, along with their status (in this case, both processes are showing up as
540135fb8e6a radixdlt/radixdlt-core:1.0-beta.40 "/opt/radixdlt/confi…" 2 hours ago Up 2 hours (healthy) 127.0.0.1:9009-9010->9009-9010/tcp radixdlt_core_1 08a190d0623e radixdlt/radixdlt-nginx:latest "/bin/sh /docker-ent…" 2 hours ago Up 2 hours (healthy) 0.0.0.0:443->443/tcp, :::443->443/tcp, 80/tcp, 0.0.0.0:30000->30000/tcp, :::30000->30000/tcp radixdlt_nginx_1
You can execute a call to the service which will respond with, amongst other things, the node’s software version number. Enter the following terminal command:
radixnode api version
The response is a
json string that carries the version number as part of its payload.
If you lose your
node-keystore.ks file then you will need to regenerate a new one and install it again. Here are the instructions for creating a key for a node running as a Docker instance, and here are the instructions for creating a key for a systemd node.
The key file contains a randomly-generated private key that determines your node’s unique address and (if choosing to register as a validator node) validator ID.
This means if you lose your key file, you will forever lose your node address and validator ID - forcing you to generate a new key file from scratch.
Any tokens held by the node address will be lost.
As a validator, your delegators will have to unstake from your validator ID and restake to your new ID.
Always make sure that you securely back up your key file as soon as you’ve generated it, and carefully protect it.
If you think the password on your keyfile has been compromised then you may want to change it without generating a new key file. (Generating a new key file has ramifications, especially for validators.)
You can use the Java
keytool tool to change the keyfile’s password. The interactive form shown below will prompt you for your old password and then your new password.
keytool -storepasswd -keystore node-keystore.ks -storetype PKCS12
Or you can just type the whole thing out on the command line:
keytool -storepasswd -keystore node-keystore.ks -storetype PKCS12 -storepass current_password -new new_password
