How to Install Hashicorp Vault on Ubuntu 20.04 LTS


In this article, I will take you through the steps to install Hashicorp vault on Ubuntu 20.04 LTS but before that let me ask you a question - Do you think Security is an important aspect when you shift your Infrastructure from on-premise environment to a Dynamic Environment ? To me, it is an utmost important thing to worry about. But don't worry, here comes the Hashicorp Vault for our rescue. Hashicorp Vault is used to secure, store and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets and other sensitive data using a UI, CLI, or HTTP API.

Step 1: Prerequisites

a) You should have a running Ubuntu 20.04 LTS Server.

b) You should have sudo or root access to run privileged commands.

c) You should have apt or apt-get utility installed in your Server.

d) You should also have curl, apt-key and apt-add-repository utility installed in your Server.


Step 2: Add GPG Key

First you need to add the Hashicorp GPG Key using curl -fsSL | sudo apt-key add - command as shown below.


Please note that here I am using root user to run all the below commands. You can use any user with sudo access to run all these commands. For more information Please check Step by Step: How to Add User to Sudoers to provide sudo access to the User.
root@localhost:~# curl -fsSL | sudo apt-key add -


Step 3: Add Repository

To download the vault package from the Hashicorp repository, you need to first add this repository to /etc/apt/sources.list file. This can be done by using an utility called apt-add-repository. You can run below command to add the Repository information.

root@localhost:~# apt-add-repository "deb [arch=amd64] $(lsb_release -cs) main"
Hit:1 focal InRelease
Get:2 focal-updates InRelease [114 kB]
Get:3 stable InRelease [7,343 B]
Get:4 focal InRelease [4,419 B]
Get:5 focal-backports InRelease [101 kB]
Get:6 focal-security InRelease [114 kB]
Get:7 stable/main amd64 Packages [7,859 B]
Ign:8 focal InRelease
Get:9 focal/main amd64 Packages [34.5 kB]
Get:10 focal-updates/main amd64 Packages [1,294 kB]
Get:11 focal InRelease [17.5 kB]
Get:12 focal-updates/main i386 Packages [550 kB]
Get:13 focal-updates/main Translation-en [269 kB]


Step 4: Update Your Server

After adding repository, you can update the Server by using apt update or apt-get update command. This command will also update the package cache with packages from Hashicorp repository.

root@localhost:~# apt update
Hit:1 focal InRelease
Get:2 focal-updates InRelease [114 kB]
Hit:3 focal InRelease
Get:4 focal-backports InRelease [101 kB]
Hit:5 stable InRelease
Get:6 focal-security InRelease [114 kB]
Ign:7 focal InRelease
Get:8 focal-updates/main amd64 DEP-11 Metadata [283 kB]
Get:9 focal InRelease [17.5 kB]


Step 5: Install Vault

Next step is to install Vault application by using apt install vault -y command as shown below. This will download and install the vault package from newly added repository.

root@localhost:~# apt install vault -y

Step 6: Check Vault version

You can check the current installed version of vault application by using vault --version command as shown below. As you can see current version is 1.8.4.

root@localhost:~# vault --version
Vault v1.8.4 (925bc650ad1d997e84fbb832f302a6bfe0105bbb)


Step 7: Check Vault Configuration

After vault installation, by default you should see below configuration which has HTTPS Listener address set to This configuration allows us to access the Vault UI using locally set IP Address. So I will leave the configuration as it is. But if you want you can modify the configuration based on your requirements.

root@localhost:~# nano /etc/vault.d/vault.hcl
# Full configuration options can be found at

ui = true

#mlock = true
#disable_mlock = true

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

#storage "consul" {
# address = ""
# path = "vault"

# HTTP listener
#listener "tcp" {
# address = ""
# tls_disable = 1

# HTTPS listener
listener "tcp" {
address = ""
tls_cert_file = "/opt/vault/tls/tls.crt"
tls_key_file = "/opt/vault/tls/tls.key"


Step 8: Start Vault Service

After setting up the required configuration, you can now start the vault service by using systemctl start vault command and then check the status by using systemctl status vault command as shown below.

root@localhost:~# systemctl start vault
root@localhost:~# systemctl status vault
● vault.service - "HashiCorp Vault - A tool for managing secrets"

You can also enable the service by using systemctl enable vault command.

root@localhost:~# systemctl enable vault
Created symlink /etc/systemd/system/ → /lib/systemd/system/vault.service.


Step 9: Access Vault UI

You can now open Web Browser and use https://<your_ip_address>:8200 URL to access the Vault UI Page. Since my local IP Address is so I am using URL to access the Page. It could be different for you.
