# Starting the Vault Server
|
|
|
|
With Vault installed, the next step is to start a Vault server.
|
|
|
|
Vault operates as a client/server application. The Vault server is the
|
|
only piece of the Vault architecture that interacts with the data
|
|
storage and backends. All operations done via the Vault CLI interact
|
|
with the server over a TLS connection.
|
|
|
|
In this page, we'll start and interact with the Vault server to understand
|
|
how the server is started, and understanding the seal/unseal process.
|
|
|
|
## Staring the Dev Server
|
|
|
|
To start, we're going to start the Vault _dev server_. The dev server
|
|
is a built-in flag to start a pre-configured server that is not very
|
|
secure but useful for playing with Vault locally. Later in the getting
|
|
started guide we'll configure and start a real server.
|
|
|
|
To start the Vault dev server, run `vault server -dev`:
|
|
|
|
```
|
|
$ vault server -dev
|
|
WARNING: Dev mode is enabled!
|
|
|
|
In this mode, Vault is completely in-memory and unsealed.
|
|
Vault is configured to only have a single unseal key. The root
|
|
token has already been authenticated with the CLI, so you can
|
|
immediately begin using the Vault CLI.
|
|
|
|
The only step you need to take is to set the following
|
|
environment variable since Vault will be taking without TLS:
|
|
|
|
export VAULT_ADDR='http://127.0.0.1:8200'
|
|
|
|
The unseal key and root token are reproduced below in case you
|
|
want to seal/unseal the Vault or play with authentication.
|
|
|
|
Unseal Key: 2252546b1a8551e8411502501719c4b3
|
|
Root Token: 79bd8011-af5a-f147-557e-c58be4fedf6c
|
|
|
|
==> Vault server configuration:
|
|
|
|
Log Level: info
|
|
Backend: inmem
|
|
Listener 1: tcp (addr: "127.0.0.1:8200", tls: "disabled")
|
|
|
|
...
|
|
```
|
|
|
|
You should see output similar to that above. As you can see, when you
|
|
start a dev server, Vault warns you loudly. The dev server stores all
|
|
its data in-memory (but still encrypted), listens on localhost without TLS, and
|
|
automatically unseals and shows you the unseal key and root access key.
|
|
We'll go over what all this means shortly.
|
|
|
|
The important thing about the dev server is that it is meant for
|
|
development only. **Do not run the dev server in production.** Even if it
|
|
was run in production, it wouldn't be very useful since it stores data in-memory
|
|
and every restart would clear all your secrets.
|
|
|
|
With the dev server running, do the following three things before anything
|
|
else:
|
|
|
|
1. Copy and run the `export VAULT_ADDR ...` command from your terminal
|
|
output. This will configure the Vault client to talk to our dev server.
|
|
|
|
2. Save the unseal key somewhere. Don't worry about _how_ to save this
|
|
securely. For now, just save it anywhere.
|
|
|
|
3. Do the same as step 2, but with the root token. We'll use this later.
|
|
|
|
## Verify the Server is Running
|
|
|
|
Verify the server is running by running `vault seal-status`. This should
|
|
succeed and exit with exit code 0. If you see an error about opening
|
|
a connection, make sure you copied and executed the `export VAULT_ADDR...`
|
|
command from above properly.
|
|
|
|
If it ran successful, the output should look like below:
|
|
|
|
```
|
|
$ vault seal-status
|
|
Sealed: false
|
|
Key Shares: 1
|
|
Key Threshold: 1
|
|
Unseal Progress: 0
|
|
```
|
|
|
|
If the output looks different, especially if the numbers are different
|
|
or the Vault is sealed, then restart the dev server and try again. The
|
|
only reason these would ever be different is if you're running a dev
|
|
server from going through this guide previously.
|
|
|
|
We'll cover what this output means later in the guide.
|
|
|
|
## Next
|
|
|
|
Congratulations! You've started your first Vault server. We haven't stored
|
|
any secrets yet, but we'll do that in the next section.
|
|
|
|
Next, we're going to
|
|
[read and write our first secrets](/intro/getting-started/first-secret.html).
