Hydra Core-Control Management Tool

This is a Streamlined CLI-Based Hydra Core Management Tool.

Installation

$ git clone https://github.com/Internet-of-People/core-control -b master

IMPORTANT NOTES

• We only support Ubuntu LTS. If you need more flexibility, use our Docker tools.
• Do not run as root!
• Installs fail2ban for ssh, and ufw allowing only port 22(ssh) and the cores ports.
• If you already use this tool, please review the changelog section.

Usage

$ cd core-control
$ NETWORK=[devnet|mainnet] ./ccontrol.sh arg1 [arg2]

For some sub-commands you can leave out the 2nd argument and the bold one will be the default.

arg1	arg2	Description
install	core	Install Core
update	core/self/check	Update Core / Core-Control / Check
remove	core/self	Remove Core / Core-Control
secret	set/clear	Delegate Secret Set / Clear
start	relay/forger/all	Start Core Services
restart	relay/forger/all/safe	Restart Core Services
stop	relay/forger/all	Stop Core Services
status	relay/forger/all	Show Core Services Status
logs	relay/forger/all	Show Core Logs
snapshot	create/restore	Snapshot Create / Restore
system	info/update	System Info / Update
config	reset	Reset Config Files to Defaults
database	clear	Clear the Database
rollback		Rollback to Specified Height
plugin	list/add/remove/update	Manage Core Plugins

Notes

• Using the 'restart safe' arguments requires the round-monitor core plugin and restarts the core services when safe to do so in order to avoid missing a block.
• When setting a delegate secret just type your secret after the 'set' argument without quotes, like below:

  $ NETWORK=[devnet|mainnet] ./ccontrol.sh secret set one two three four five six seven eight nine ten eleven twelve

• When doing a rollback just type the desired height after the rollback argument.
• Rollback will stop the running processes, do the rollback and start the processes that were online.
• The script adds an alias named ccontrol on first run. On your next shell login you'll be able to call the script from anywhere using: ccontrol arg1 [arg2]. It also has autocomplete functionality for all possible arguments.
• Using the config reset arguments will stop the core processes, delete your existing configs and replace them with the defaults. If you're running a forger and/or have custom settings, you should add them again.
• Using the database clear arguments will stop the core processes, wipe the database clean, and start the processes that were online before. The end result is that your node will start syncing from 0.
• For plugin management just type the name of the plugin after plugin add/remove/update as it appears in the list.
• On first run the tool exposes the core-cli with the project name, e.g. hydra for project Hydra. It will be accessible after logout.
