Installing node.sh

One-line install (recommended)

One command installs the script. On a host that already runs a node, it also migrates that node onto Elastos Node for Ubuntu. It verifies the published SHA-256 checksum and never touches keystores or chain data:

$ curl -fsSL https://raw.githubusercontent.com/elastos/Elastos.Node/master/build/skeleton/install.sh | bash
  • On a fresh host it installs node.sh into ~/node and points you to node.sh setup.
  • On an existing node (the original Elastos.Node runner or an earlier version) it backs up the old node.sh, swaps in Elastos Node for Ubuntu, and runs migrate, which restarts nothing.

To review the installer before running it, download it first:

$ curl -fsSL -o install.sh https://raw.githubusercontent.com/elastos/Elastos.Node/master/build/skeleton/install.sh
$ less install.sh && bash install.sh

After installing on a fresh host, run the turnkey setup, which installs dependencies, adds swap, configures the firewall, enables autostart, and initializes the node:

$ node.sh setup

See Running node.sh for what setup does and the manual alternative.

Manual install (alternative)

To place the script by hand, create a folder in your $HOME to hold the executable, config, and data files:

$ mkdir ~/node
$ cd ~/node

Download the current version of the script and make it executable:

$ curl -fsSLO https://raw.githubusercontent.com/elastos/Elastos.Node/master/build/skeleton/node.sh
$ chmod a+x node.sh

Once installed, keep the script current with the checksum-verified self-update:

$ node.sh update_script
