Sample init scripts and service configuration for dashd
|
|
==========================================================
|
|
|
|
Sample scripts and configuration files for systemd, Upstart and OpenRC
|
|
can be found in the contrib/init folder.
|
|
|
|
contrib/init/dashd.service: systemd service unit configuration
|
|
contrib/init/dashd.openrc: OpenRC compatible SysV style init script
|
|
contrib/init/dashd.openrcconf: OpenRC conf.d file
|
|
contrib/init/dashd.conf: Upstart service configuration file
|
|
contrib/init/dashd.init: CentOS compatible SysV style init script
|
|
|
|
Service User
|
|
---------------------------------
|
|
|
|
All three Linux startup configurations assume the existence of a "dashcore" user
|
|
and group. They must be created before attempting to use these scripts.
|
|
The macOS configuration assumes dashd will be set up for the current user.
|
|
|
|
Configuration
|
|
---------------------------------
|
|
|
|
Running dashd as a daemon does not require any manual configuration. You may
|
|
set the `rpcauth` setting in the `dash.conf` configuration file to override
|
|
the default behaviour of using a special cookie for authentication.
|
|
|
|
This password does not have to be remembered or typed as it is mostly used
|
|
as a fixed token that dashd 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 dashd is run with the "-server" flag (set by default), and no rpcpassword is set,
|
|
it will use a special cookie file for authentication. The cookie is generated with random
|
|
content when the daemon starts, and deleted when it exits. Read access to this file
|
|
controls who can access it through RPC.
|
|
|
|
By default the cookie is stored in the data directory, but it's location can be overridden
|
|
with the option '-rpccookiefile'.
|
|
|
|
This allows for running dashd without having to do any manual configuration.
|
|
|
|
`conf`, `pid`, and `wallet` accept relative paths which are interpreted as
|
|
relative to the data directory. `wallet` *only* supports relative paths.
|
|
|
|
For an example configuration file that describes the configuration settings,
|
|
see `contrib/debian/examples/dash.conf`.
|
|
|
|
Paths
|
|
---------------------------------
|
|
|
|
### Linux
|
|
|
|
All three configurations assume several paths that might need to be adjusted.
|
|
|
|
Binary: `/usr/bin/dashd`
|
|
Configuration file: `/etc/dashcore/dash.conf`
|
|
Data directory: `/var/lib/dashd`
|
|
PID file: `/var/run/dashd/dashd.pid` (OpenRC and Upstart) or `/run/dashd/dashd.pid` (systemd)
|
|
Lock file: `/var/lock/subsys/dashd` (CentOS)
|
|
|
|
The PID directory (if applicable) and data directory should both be owned by the
|
|
dashcore user and group. It is advised for security reasons to make the
|
|
configuration file and data directory only readable by the dashcore user and
|
|
group. Access to dash-cli and other dashd rpc clients can then be
|
|
controlled by group membership.
|
|
|
|
NOTE: When using the systemd .service file, the creation of the aforementioned
|
|
directories and the setting of their permissions is automatically handled by
|
|
systemd. Directories are given a permission of 710, giving the dashcore user and group
|
|
access to files under it _if_ the files themselves give permission to the
|
|
dashcore user and group to do so (e.g. when `-sysperms` is specified). This does not allow
|
|
for the listing of files under the directory.
|
|
|
|
NOTE: It is not currently possible to override `datadir` in
|
|
`/etc/dash/dash.conf` with the current systemd, OpenRC, and Upstart init
|
|
files out-of-the-box. This is because the command line options specified in the
|
|
init files take precedence over the configurations in
|
|
`/etc/dash/dash.conf`. However, some init systems have their own
|
|
configuration mechanisms that would allow for overriding the command line
|
|
options specified in the init files (e.g. setting `BITCOIND_DATADIR` for
|
|
OpenRC).
|
|
|
|
### macOS
|
|
|
|
Binary: `/usr/local/bin/dashd`
|
|
Configuration file: `~/Library/Application Support/DashCore/dash.conf`
|
|
Data directory: `~/Library/Application Support/DashCore`
|
|
Lock file: `~/Library/Application Support/DashCore/.lock`
|
|
|
|
Installing Service Configuration
|
|
-----------------------------------
|
|
|
|
### systemd
|
|
|
|
Installing this .service file consists of 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 dashd` and to enable for system startup run
|
|
`systemctl enable dashd`
|
|
|
|
NOTE: When installing for systemd in Debian/Ubuntu the .service file needs to be copied to the /lib/systemd/system directory instead.
|
|
|
|
### OpenRC
|
|
|
|
Rename dashd.openrc to dashd and drop it in /etc/init.d. Double
|
|
check ownership and permissions and make it executable. Test it with
|
|
`/etc/init.d/dashd start` and configure it to run on startup with
|
|
`rc-update add dashd`
|
|
|
|
### Upstart (for Debian/Ubuntu based distributions)
|
|
|
|
Upstart is the default init system for Debian/Ubuntu versions older than 15.04. If you are using version 15.04 or newer and haven't manually configured upstart you should follow the systemd instructions instead.
|
|
|
|
Drop dashd.conf in /etc/init. Test by running `service dashd 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 utility.
|
|
|
|
### CentOS
|
|
|
|
Copy dashd.init to /etc/init.d/dashd. Test by running `service dashd start`.
|
|
|
|
Using this script, you can adjust the path and flags to the dashd program by
|
|
setting the DASHD and FLAGS environment variables in the file
|
|
/etc/sysconfig/dashd. You can also use the DAEMONOPTS environment variable here.
|
|
|
|
### macOS
|
|
|
|
Copy org.dash.dashd.plist into ~/Library/LaunchAgents. Load the launch agent by
|
|
running `launchctl load ~/Library/LaunchAgents/org.dash.dashd.plist`.
|
|
|
|
This Launch Agent will cause dashd to start whenever the user logs in.
|
|
|
|
NOTE: This approach is intended for those wanting to run dashd as the current user.
|
|
You will need to modify org.dash.dashd.plist if you intend to use it as a
|
|
Launch Daemon with a dedicated dashcore user.
|
|
|
|
Auto-respawn
|
|
-----------------------------------
|
|
|
|
Auto respawning is currently only configured for Upstart and systemd.
|
|
Reasonable defaults have been chosen but YMMV.
