Service User +--------------------------------- + +All three startup configurations assume the existence of a "bitcoin" user +and group.

Configuration +--------------------------------- + +At a bare minimum, bitcoind requires that the rpcpassword setting be set +when running as a daemon. If the configuration file does not exist or this +setting is not set, bitcoind will shutdown promptly after startup. + +This password does not have to be remembered or typed as it is mostly used +as a fixed token that bitcoind and client programs read from the configuration +file, however it is recommended that a strong and secure password be used +as this password is security critical to securing the wallet should the +wallet be enabled. + +If bitcoind is run with "-daemon" flag, and no rpcpassword is set, it will +print a randomly generated suitable password to stderr. You can also +generate one from the shell yourself like this: + +bash -c 'tr -dc a-zA-Z0-9 < /dev/urandom | head -c32 && echo' + +Once you have a password in hand, set rpcpassword= in /etc/bitcoin/bitcoin.conf + +For an example configuration file that describes the configuration settings, +see contrib/debian/examples/bitcoin.conf. + +3.

It is advised for security +reasons to make the configuration file and data directory only readable by the +bitcoin user and group. Access to bitcoin-cli and other bitcoind rpc clients +can then be controlled by group membership. + +4.
