vault学习笔记

1 vault开启

vault server -dev(开发者模式)

vault server -config=config.hcl（生产环境启动方式）

其中config.hcl内容如下，本地安装配置mysql数据库，ui=true可以访问ui界面

disable_mlock  = true
ui=true
storage "mysql" {
    address = "127.0.0.1:3306"
    username = "root"
    password = "123456"
    database = "vault"
    table = "vault"
}
listener "tcp" {
 address     = "127.0.0.1:8200"
 tls_disable = 1
}

2 vault_addr设置

另外启动一个控制台界面

windows环境：set  VAULT_ADDR=http://127.0.0.1:8200

linux环境：export VAULT_ADDR=http://127.0.0.1:8200

3 vault初始化

   vault operator init或者vault operator init -key-shares=5 -key-threshold=3

说明：
    -key-shares：指定秘钥的总股数，
    -key-threshold：指定需要几股可解锁
    以上参数为默认，可不设置。

得到五个key(key1到key5)，后续解封用

vault operator unseal key1

vault operator unseal key2

vault operator unseal key3

vault status查看状态，sealed为false表示解封了

Key             Value
---             -----
Seal Type       shamir
Initialized     true
Sealed          false
Total Shares    5
Threshold       3
Version         1.2.3
Cluster Name    vault-cluster-181def04
Cluster ID      32b31c01-4c2e-bfcf-e44c-0abc862d6156
HA Enabled      false

4 用产生的token登陆
vault login XXX

5 数据库使用
vault secrets enable database

6 transit使用(在path=encryption)启动transit，不写-path=encryption则默认在transit路径下

vault secrets enable -path=encryption transit

7 写入数据库连接配置

vault write database/config/my-mysql-database
    plugin_name=mysql-database-plugin
    connection_url="{{username}}:{{password}}@tcp(127.0.0.1:3306)/"
    allowed_roles="my-role"
    username="root"
    password="123456"

 

8 设置动态密钥策略
vault write database/roles/my-role
    db_name=my-mysql-database
    creation_statements="CREATE USER '{{name}}'@'%' IDENTIFIED BY '{{password}}';GRANT SELECT,INSERT,UPDATE ON *.* TO '{{name}}'@'%';"
    default_ttl="1h"
    max_ttl="24h"

 

9 配置文件，直接编写vault policy write my-policy my-policy.hcl没有成功，通过以下命令实现

vault policy write my-policy -<<EOF
# Normal servers have version 1 of KV mounted by default, so will need these
# paths:
path "secret/*" {
  capabilities = ["create"]
}
path "secret/foo" {
  capabilities = ["read"]
}

# Dev servers have version 2 of KV mounted by default, so will need these
# paths:
path "secret/data/*" {
  capabilities = ["create"]
}
path "secret/data/foo" {
  capabilities = ["read"]
}
EOF

 

 

vault 设置静态role

0 在mysql中建立一个角色vault-edu

1 设置运行连接数据库 vault secrets enable database

2 设置数据库连接

vault write database/config/my-mysql-database plugin_name=mysql-database-plugin connection_url="{{username}}:{{password}}@tcp(30.16.104.43:3306)/" allowed_roles="*" username="root" password="123456"

3建立静态角色education

vault write database/static-roles/education db_name=my-mysql-database rotation_statements=@rotation.sql username="vault-edu" rotation_period=86400

rotation.sql具体内容如下：
ALTER USER '{{name}}'@'%' IDENTIFIED BY '{{password}}';

4 读取education信息

vault read database/static-roles/education

5 新建一个策略app,并且写入vault策略中，分配对应的token

vault policy write app app.hcl

vault token create -policy="app"

6 用分配的token登录，查看对应的角色信息

VAULT_TOKEN=s.NN5Izfj9ok3VuZiaP9N9QJ1V vault read database/static-creds/education

设置vault角色

vault write database/roles/my-role
db_name=my-mysql-database
creation_statements="CREATE USER '{{name}}'@'%' IDENTIFIED BY '{{password}}';GRANT SELECT,INSERT,UPDATE ON *.* TO '{{name}}'@'%';"
default_ttl="1h"
max_ttl="24h“

vault生产环境配置

https://learn.hashicorp.com/tutorials/vault/configure-vault

激活vault加密轮转密钥参考https://learn.hashicorp.com/tutorials/vault/eaas-transit

To rotate the encryption key, invoke the transit/keys/<key_ring_name>/rotate endpoint.

例如：vault write -f transit/keys/order/rotate

# List available auth method path "sys/auth" { capabilities = [ "read" ] } # Read default token configuration path "sys/auth/token/tune" { capabilities = [ "read", "sudo" ] } # Create and manage tokens (renew, lookup, revoke, etc.) path "auth/token/*" { capabilities = [ "create", "read", "update", "delete", "list", "sudo" ] } # For Advanced Features - list available secrets engines path "sys/mounts" { capabilities = [ "read" ] } # For Advanced Features - tune the database secrets engine TTL path "sys/mounts/database/tune" { capabilities = [ "update" ] }
