Overview

The greptime command can start/stop GreptimeDB and pass configuration options.

Install the Greptime CLI

The Greptime CLI comes bundled with the GreptimeDB binary. After installing GreptimeDB, you can execute the ./greptime command within the GreptimeDB directory.

For convenience, if you wish to run commands using greptime instead of ./greptime, consider moving the CLI binary to your system's bin directory or appending the binary's path to your PATH environment variable.
