Vault从入门到精通系列之二：启动Vault服务器

一、启动开发服务器
二、设置环境变量
三、验证服务器正在运行
四、vault命令汇总

Vault 作为客户端-服务器应用程序运行。Vault 服务器是唯一与数据存储和后端交互的 Vault 架构。通过 Vault CLI 完成的所有操作都通过 TLS 连接与服务器交互。

在本篇博客中，启动以开发模式运行的 Vault 服务器并与之交互。

一、启动开发服务器

以开发模式（开发服务器）启动 Vault 服务器。开发服务器是一个内置的、预配置的服务器，它不是很安全，但对于在本地使用 Vault 很有用。

vault server -dev

输出如下所示：

vault server -dev
==> Vault server configuration:

2023-06-19T13:14:08.703+0800 [INFO]  core: successful mount: namespace="" path=secret/ type=kv version=""
WARNING! dev mode is enabled! In this mode, Vault runs entirely in-memory
and starts unsealed with a single unseal key. The root token is already
authenticated to the CLI, so you can immediately begin using Vault.

You may need to set the following environment variables:

    $ export VAULT_ADDR='http://127.0.0.1:8200'

The unseal key and root token are displayed below in case you want to
seal/unseal the Vault or re-authenticate.

Unseal Key: jp2vzZPjYufsXNsJsEFTuKHMJzvx2FvnC5M3H6+y3vc=
Root Token: hvs.WNSdITpoYX5HvRZWYyGjvZaj

Development mode should NOT be used in production installations!

开发服务器将其所有数据存储在内存中（但仍然加密），在localhost没有 TLS 的情况下进行侦听，并自动解封并向您显示解封密钥和根访问密钥。

二、设置环境变量

启动一个新的终端会话。

export VAULT_ADDR …从终端输出复制并运行命令。这将配置 Vault 客户端与开发服务器对话。

export VAULT_ADDR='http://127.0.0.1:8200'

Vault CLI 使用环境变量确定哪些 Vault 服务器发送请求 VAULT_ADDR。

将解封密钥保存在某处。不要担心如何安全地保存它。现在，只需将它保存在任何地方。

将环境变量值VAULT_TOKEN设置为终端输出中显示的生成的根令牌值。

export VAULT_TOKEN="hvs.6j4cuewowBGit65rheNoceI7"

要与 Vault 交互，必须提供有效的令牌。设置此环境变量是一种通过 CLI 向 Vault 提供令牌的方法。在身份验证教程中，将学习使用vault login <token_value>命令对 Vault 进行身份验证。

三、验证服务器正在运行

通过运行命令验证服务器是否正在运行vault status。如果运行成功，输出应如下所示：

vault status
Key             Value
---             -----
Seal Type       shamir
Initialized     true
Sealed          false
Total Shares    1
Threshold       1
Version         1.13.3
Build Date      2023-06-06T18:12:37Z
Storage Type    inmem
Cluster Name    vault-cluster-488bbee6
Cluster ID      6fd0289e-dd56-af7f-c188-6f8ea08e3f2e
HA Enabled      false

四、vault命令汇总

在开发模式下运行 Vault 时，Key/Value v2 机密引擎在 secret/ 路径下启用。Key/Value 机密引擎是一个通用的键值存储，用于在为 Vault 配置的物理存储中存储任意机密。写入 Vault 的秘密被加密，然后写入后端存储。因此，后端存储机制永远看不到未加密的值，也没有必要的手段在没有 Vault 的情况下对其进行解密。

Key/Value 机密引擎有版本 1 和 2。不同之处在于 v2 提供机密的版本控制，而 v1 不提供。

使用 vault kv [options] [args] 命令与 K/V 秘密引擎交互。
