Service User +--------------------------------- + +All three startup configurations assume the existence of a "bitcoin" user +and group. They must be created before attempting to use these scripts. + +2. 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. Paths +--------------------------------- + +All three configurations assume several paths that might need to be adjusted. + +Binary: /usr/bin/bitcoind +Configuration file: /etc/bitcoin/bitcoin.conf +Data directory: /var/lib/bitcoind +PID file: /var/run/bitcoind/bitcoind.pid (OpenRC and Upstart) + /var/lib/bitcoind/bitcoind.pid (systemd) + +The configuration file, PID directory (if applicable) and data directory +should all be owned by the bitcoin user and group. 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. Installing Service Configuration +----------------------------------- + +4a) systemd + +Installing this .service file consists on just copying it to +/usr/lib/systemd/system directory, followed by the command +"systemctl daemon-reload" in order to update running systemd configuration. + +To test, run "systemctl start bitcoind" and to enable for system startup run +"systemctl enable bitcoind" + +4b) OpenRC + +Rename bitcoind.openrc to bitcoind and drop it in /etc/init.d. Double +check ownership and permissions and make it executable. Test it with +"/etc/init.d/bitcoind start" and configure it to run on startup with +"rc-update add bitcoind" + +4c) Upstart (for Debian/Ubuntu based distributions) + +Drop bitcoind.conf in /etc/init. Test by running "service bitcoind start" +it will automatically start on reboot. + +NOTE: This script is incompatible with CentOS 5 and Amazon Linux 2014 as they +use old versions of Upstart and do not supply the start-stop-daemon uitility. + +5. Auto-respawn +----------------------------------- + +Auto respawning is currently only configured for Upstart and systemd. +Reasonable defaults have been chosen but YMMV. + + |
