1 | Sample init scripts and service configuration for bitcoind |
| 2 | ========================================================== | |
| 3 | ||
| 4 | Sample scripts and configuration files for systemd, Upstart and OpenRC | |
| 5 | can be found in the contrib/init folder. | |

7 | contrib/init/bitcoind.service: systemd service unit configuration |
| 8 | contrib/init/bitcoind.openrc: OpenRC compatible SysV style init script | |
| 9 | contrib/init/bitcoind.openrcconf: OpenRC conf.d file | |
| 10 | contrib/init/bitcoind.conf: Upstart service configuration file | |

| 13 | 1. Service User | |
| 14 | --------------------------------- | |
| 15 | ||
| 16 | All three startup configurations assume the existence of a "bitcoin" user | |
| 17 | and group. They must be created before attempting to use these scripts. | |
| 18 | ||
| 19 | 2. Configuration | |
| 20 | --------------------------------- | |
| 21 | ||
| 22 | At a bare minimum, bitcoind requires that the rpcpassword setting be set | |
| 23 | when running as a daemon. If the configuration file does not exist or this | |
| 24 | setting is not set, bitcoind will shutdown promptly after startup. | |
| 25 | ||
| 26 | This password does not have to be remembered or typed as it is mostly used | |
| 27 | as a fixed token that bitcoind and client programs read from the configuration | |
| 28 | file, however it is recommended that a strong and secure password be used | |
| 29 | as this password is security critical to securing the wallet should the | |
| 30 | wallet be enabled. | |
| 31 | ||
| 32 | If bitcoind is run with "-daemon" flag, and no rpcpassword is set, it will | |
| 33 | print a randomly generated suitable password to stderr. You can also | |
| 34 | generate one from the shell yourself like this: | |
| 35 | ||
| 36 | bash -c 'tr -dc a-zA-Z0-9 < /dev/urandom | head -c32 && echo' | |
| 37 | ||
| 234bfbf6 | 38 | |
| 4fbfebea | 39 | For an example configuration file that describes the configuration settings, |
| 234bfbf6 AW |
40 | see contrib/debian/examples/bitcoin.conf. |
| 41 | ||
| 42 | 3. Paths | |
| 43 | --------------------------------- | |
| 44 | ||
| 45 | All three configurations assume several paths that might need to be adjusted. | |
| 46 | ||
| 47 | Binary: /usr/bin/bitcoind | |
| 48 | Configuration file: /etc/bitcoin/bitcoin.conf | |
| 49 | Data directory: /var/lib/bitcoind | |
| 50 | PID file: /var/run/bitcoind/bitcoind.pid (OpenRC and Upstart) | |
| 51 | /var/lib/bitcoind/bitcoind.pid (systemd) | |
| 723664b5 | 52 | Lock file: /var/lock/subsys/bitcoind (CentOS) |
| 234bfbf6 AW |
53 | |
| 54 | The configuration file, PID directory (if applicable) and data directory | |
| 55 | should all be owned by the bitcoin user and group. It is advised for security | |
| 56 | reasons to make the configuration file and data directory only readable by the | |
| 57 | bitcoin user and group. Access to bitcoin-cli and other bitcoind rpc clients | |
| 58 | can then be controlled by group membership. | |
| 59 | ||
| 60 | 4. Installing Service Configuration | |
| 61 | ----------------------------------- | |
| 62 | ||
| 63 | 4a) systemd | |
| 64 | ||
| 7e6d23b1 | 65 | Installing this .service file consists of just copying it to |
| 234bfbf6 AW |
66 | /usr/lib/systemd/system directory, followed by the command |
| 67 | "systemctl daemon-reload" in order to update running systemd configuration. | |
| 68 | ||
| 69 | To test, run "systemctl start bitcoind" and to enable for system startup run | |
| 70 | "systemctl enable bitcoind" | |
| 71 | ||
| 72 | 4b) OpenRC | |
| 73 | ||
| 74 | Rename bitcoind.openrc to bitcoind and drop it in /etc/init.d. Double | |
| 75 | check ownership and permissions and make it executable. Test it with | |
| 76 | "/etc/init.d/bitcoind start" and configure it to run on startup with | |
| 77 | "rc-update add bitcoind" | |
| 78 | ||
| 79 | 4c) Upstart (for Debian/Ubuntu based distributions) | |
| 80 | ||
| 81 | Drop bitcoind.conf in /etc/init. Test by running "service bitcoind start" | |
| 82 | it will automatically start on reboot. | |
| 83 | ||
| 84 | NOTE: This script is incompatible with CentOS 5 and Amazon Linux 2014 as they | |
| 723664b5 | 85 | use old versions of Upstart and do not supply the start-stop-daemon utility. |
| 86 | ||
| 87 | 4d) CentOS | |
| 88 | ||
| 89 | Copy bitcoind.init to /etc/init.d/bitcoind. Test by running "service bitcoind start". | |
| 90 | ||
| 4fbfebea MC |
91 | Using this script, you can adjust the path and flags to the bitcoind program by |
| 92 | setting the BITCOIND and FLAGS environment variables in the file | |
| 723664b5 | 93 | /etc/sysconfig/bitcoind. You can also use the DAEMONOPTS environment variable here. |

94 | |
| 95 | 5. Auto-respawn | |
| 96 | ----------------------------------- | |
| 97 | ||
| 98 | Auto respawning is currently only configured for Upstart and systemd. | |
| 99 | Reasonable defaults have been chosen but YMMV. | |
