Usage: vault server [options]
Start a Vault server.
This command starts a Vault server that responds to API requests.
Vault will start in a "sealed" state. The Vault must be unsealed
with "vault unseal" or the API before this server can respond to requests.
This must be done for every server.
If the server is being started against a storage backend that has
brand new (no existing Vault data in it), it must be initialized with
"vault init" or the API first.
General Options:
-config=<path> Path to the configuration file or directory. This can be
specified multiple times. If it is a directory, all
files with a ".hcl" or ".json" suffix will be loaded.
