Configuring Bitcoin Core connections and procedure procedure (RPC) in the local network
When configuring the bitcoin node on a small computer, you take a significant step towards the decentralized cryptocurrency ecosystem. In this article, we will go through the appropriate configuration and command to start Bitcoin Core and enable remote connections of procedures (RPC) for remote access to the LAN.
preliminary requirements
- Bitcoin node with Bitcoin core version 0.15.3 or newer
- Ethernet connection on your small computer
- Computer IP address
Step by step instructions
1. Install the Bitcoin core
First, download and install the Bitcoin core from the official repository: [ (version 0.15.3 or newer)
Follow the installation instructions for your operating system:
* Ubuntu/Debian : Sudo apt-get Instalate Bitcoin-Qt
* Fedora/Centos/Rhel : Sudo DNF Instal Instalate Bitcoin-QT
* Arch Linux : Sudo Pacman -s Bitcoin -qt
2. Start Bitcoin Core
Start the Bitcoin junction, launching:
`
Bitcoin-QT
`
This will start the knot and start listening to incoming connections.
3. Configure RPC settings
To enable remote procedure (RPC) for the node, you need to configure some settings:
- RPCUSER
: Enter the username for your node.
- RPCPassword : Enter the password for your node.
- RPCPORT
: Set the port number where your node will listen.
For example:
`
Bitcoin-QT
> RPCSET
rpcuser = myusername
rpcpassword = myPassword
RPCPORT = 55555
Bitcoin-QT (version 0.15.3)
`
4. Start the RPC server
After configuring the RPC settings, start the RPC server, launching:
`
Bitcoin -qt -RPCPORT = 55555
`
This will launch the RPC server and start listening to incoming connections with LAN.
Using the RPC to access the node
To access the node remotely with the RPC, you must:
- Get the Bitcoin address : You can get a bitcoin address by launching:
`
Bitcoincli Getaddresslist
`
Choose a new address and save it to the file (e.g. “Myaddress.txt).
2.
You can now use this URL RPC to send bitcoin transactions, download information about transaction or remotely perform other tasks related to the node.
Tips and variants
- If you want to use a specific port for RPC connections, you can specify it in the "Bitcoin-QT" command:
Bitcoin -qt -RPCPORT = 8080
`
- You can also configure many RPC users and passwords using the “-RPCUSER” option:
`
Bitcoin -qt -RPCUSER = Myusername -RPCASSWORD = MyPassword -rPCPORT = 55555
`
Remember to replace ` ‘to the IP address of the actual computer.
By following these steps, you will be able to configure the Bitcoin node on your small computer and turn on remote connections of procedures (RPC) for remote access from the LAN. Happy extraction!
