1.yum安装

yum install -y yum-utils

yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

yum -y install vault

2.修改配置文档：

[root@es-sky-131 tls]# cat /etc/vault.d/vault.hcl
# Full configuration options can be found at https://www.vaultproject.io/docs/configuration

ui = true

#mlock = true
#disable_mlock = true

storage "file" {
  path = "/opt/vault/data"
}

#storage "consul" {
#  address = "127.0.0.1:8500"
#  path    = "vault"
#}

# HTTP listener
#listener "tcp" {
#  address = "127.0.0.1:8200"
#  tls_disable = 1
#}

# HTTPS listener
listener "tcp" {
  address       = "0.0.0.0:8200"
  tls_cert_file = "/opt/vault/tls/server.crt"
  tls_key_file  = "/opt/vault/tls/server.key"
}

# Enterprise license_path
# This will be required for enterprise as of v1.8
#license_path = "/etc/vault.d/vault.hclic"

# Example AWS KMS auto unseal
#seal "awskms" {
#  region = "us-east-1"
#  kms_key_id = "REPLACE-ME"
#}

# Example HSM auto unseal
#seal "pkcs11" {
#  lib            = "/usr/vault/lib/libCryptoki2_64.so"
#  slot           = "0"
#  pin            = "AAAA-BBBB-CCCC-DDDD"
#  key_label      = "vault-hsm-key"
#  hmac_key_label = "vault-hsm-hmac-key"
#}

3.初始化：（由于自生成的证书有问题，需要重新生成）

cd /opt/vault/tls/ openssl genrsa -out ca.key 2048 openssl req -x509 -new -nodes -key ca.key -subj "/O=HashiCorp /CN=Vault" -days 34000 -out ca.crt openssl genrsa -out server.key 2048 openssl req -new -key server.key -config test.cnf -subj "/CN=Vault" -out server.csr openssl x509 -req -in server.csr -CA /opt/vault/tls/ca.crt -CAkey /opt/vault/tls/ca.key -CAcreateserial -days 36500 -extensions v3_req -extfile test.cnf -out server.crt cp /opt/vault/tls/ca.* /etc/ssl/certs/

Please securely distribute the key shares printed above. When the Vault is re-sealed, restarted, or stopped, you must supply at least 3 of these keys to unseal it before it can start servicing requests.   Vault does not store the generated master key. Without at least 3 keys to reconstruct the master key, Vault will remain permanently sealed!   It is possible to generate new unseal keys, provided you have a quorum of existing unseal keys shares. See "vault operator rekey" for more information.

2.初始化可以指定参数

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

# -key-shares：指定密钥的总股数， 

# -key-threshold：指定需要几股可解锁
