4d14d06fc docs: clarified systemd installation instructions in init.md for Ubuntu users. (DaveFromBinary)
Pull request description:
Added a note to init.md to clarify the .service copy path for Ubuntu because it differs from the described copy path.
Also noted which version of Ubuntu switched to systemd for the default system init to clarify when the systemd installation steps should be used instead of the upstart installation steps for Ubuntu users.

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 OS X configuration assumes dashd will be set up for the current user.
|
|
|
|
Configuration
|
|
---------------------------------
|
|
|
|
At a bare minimum, dashd 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, dashd 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 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 `/var/lib/dashd/dashd.pid` (systemd)
|
|
Lock file: `/var/lock/subsys/dashd` (CentOS)
|
|
|
|
The configuration file, PID directory (if applicable) and data directory
|
|
should all 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.
|
|
|
|
### Mac OS X
|
|
|
|
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.
|
|
|
|
### Mac OS X
|
|
|
|
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.
