Changing Bitcoin Core User to “coindog” on Linux
I see that you have encountered a common problem with installing Bitcoin Core under the main system user “dog” on Linux. Unfortunately, this can lead to conflicts and make it difficult to manage access to your wallet. In this article, we will go through the steps to change the Bitcoin Core user to “coindog”.
Why is this necessary?
When you install Bitcoin Core using the apt
or yum
package manager, it creates a new user account with the same name as the Bitcoin Core executable (usually bitcoin-core
). This can cause problems when trying to access your wallet through the default user interface. By changing the Bitcoin Core user to “coindog”, we ensure that your wallet is only accessible to the newly created user “coindog”.
Step by Step Instructions:
- List Existing Users: First, let’s list all existing users on the system using the
getent
command:
$ getent passwd | grep bitcoin-core
This will show you a list of users that were created by Bitcoin Core during its installation.
- Find the User ID for ‘coindog’
: Next, we need to find the User ID (UID) associated with the ‘coindog’ account. You can do this using the
id
command:
$ id coindog
This will show you the UID and GID of the ‘coindog’ account.
- Change the Bitcoin Core user to “coindog”: Now we will update the Bitcoin Core configuration file (
/etc/bitcoin.conf
) to use the new UID:
$ sudo nano /etc/bitcoin.conf
Find the line “user = dog” and replace it with:
user = coindog
Save and exit the editor.
- Update the Bitcoin Core executable: After making the change, update the Bitcoin Core executable to use the new UID:
$ sudo rm /usr/local/bin/bitcoin-core && sudo mv bitcoin-core coindog
This will move the Bitcoin Core executable to a new location (“coindog”) and rename it to “bitcoin-core”.
- Reinstall Bitcoin Core: Finally, reinstall Bitcoin Core using the updated user ID:
$ sudo apt install --reinstall bitcoin-core
- Test your wallet
: After installing the updated Bitcoin Core, test your wallet by accessing it via a browser or command line interface.
Tips and Precautions:
- Make sure to update all existing wallets on the system using
apt-get
oryum
before attempting to change the user.
- Be careful when changing user IDs as this can cause problems with other applications that use the same UID.
- If you encounter any errors during these steps, consult the Bitcoin Core documentation and troubleshooting guides for help.
By following these steps, you should be able to successfully change your Bitcoin Core user to coindog
on Linux.
