Set Up VPS on Linode - Part 1

Recently I had to set up virtual-private-server (VPS) for both my personal blog the Good, the Bad, and the Curious and Linkqlo's website. Here is my workflow to set up Ubuntu Linux, Apache server and the server environment on Linode, which is one of the more popular VPS service providers along with Digital Ocean. Linode's Getting Started Guide is a helpful reference for the basics.

Activate New Instance on Linode

Pick Linode's cheapest VPS tier Linode 1024 at $5/month with 20GB storage, 1 CPU Core and 1TB XFER.

Choose a location. I just go with Fremont, CA, which is the closest one from where I live. When a new instance is created, it will get assigned an IP address. Its server status is Brand New.

Enable backup for $2/month. Pick a weekly backup window of 0200-0400 on every Sunday.

On Dashboard, deploy an image to choose a Linux distribution of Ubuntu 16.04 LTS. By default, the largest available space will be allocated. Enter 20224 MB for Deployment Disk Size and 256 MB for Swap Disk. Pick a strong root SSH password. Server status now reads: Powered Off.

Click Boot to turn on the instance. Server status is now changed to Running.

When a new instance is created, it will have a random serial number. Go to Dashboard/Settings/Display Settings to change it to a more meaningful name (save your Greek mythology vocabulary for later use, not here).

Set Up SSH Access

I use iTerm2 on MacBook in place of the default from OSX.

My current favorite color theme is Arthur, which can be downloaded from iTerm2 Color Theme Collection.

Go to Linode's Dashboard, pick the newly created instance, go to tab Remote Access. Note down the public IP address in IPv4 format. Say, it's

Log in for the first time as root

ssh root@

Answer yes when prompted for continuing connecting to this new host, where authenticity cannot be established yet. After is permanently added to the list of known hosts, the connection will be closed.

SSH as root again, with password this time:

ssh root@

Upon successful login, Ubuntu's welcome message will be displayed, displaying it's on 16.04.2 LTS distribution.

Add New Sudo User

Digital Ocean's Guide is a helpful starting reference.

As root user,

adduser userjoe

Provide answers to complete creating userjoe:

  • Password
  • Full Name (optional)
  • Room Number (optional)
  • Work Phone (optional)
  • Home Phone (optional)
  • Other (optional)

Grant this new user sudo privilege,

usermod -aG sudo userjoe

Check all current users with sudo privileges:

getent group sudo

Provide the following info to user usejoe:

Username:       userjoe
Password:       joespassword

Test the new user login. Logout from root, then login as userjoe with the assigned password.

ssh userjoe@

Once sudo user userjoe is created, it's better to complete the rest of the server setup with userjoe (by using sudo command) rather than root. Login with root should be limited to the minimum.

To disallow root logins over SSH, as userjoe,

sudo vim /etc/ssh/sshd_config

Set the following from yes to no:

PermitRootLogin no

Configure Server Environment

Set Hostname

The server prompt is originally something like:


That's not very sexy. Time to set an interesting hostname for the instance. Go with something memorable and unique, like planets, philosophers, animals, or greek gods.

Here's a helpful list of greek gods and goddesses, and what they represent.

As userjoe, set hostname to apollo,

sudo hostnamectl set-hostname apollo

Log out and log in back again. The prompt now reads:


Set Local Time

By default, Linux's image will be set to UTC time (Greenwich Mean Time). Change this to the local server time with:

sudo dpkg-reconfigure tzdata

Pick US and Pacific-New,

Current default time zone: 'US/Pacific-New'
Local time is now:      Fri Apr  7 21:51:25 PDT 2017.
Universal Time is now:  Sat Apr  8 04:51:25 UTC 2017.

Set Up Passwordless SSH Login

Generate public and private SSH keys on the local machine (or your local server, or whatever server you use as the entry point to SSH into other realms):


The key pair will be generated and saved in ~/.ssh as:

  • id_rsa

Copy the public key to server apollo using SSH:

cat ~/.ssh/ | ssh userjoe@ "mkdir -p ~/.ssh && cat >>  ~/.ssh/authorized_keys"

Configure SSH

On the local machine, edit the SSH configuration file:

vim ~/.ssh/config

Add this entry to the file:

host apollo
    User userjoe

Now, instead of using the clumsy ssh userjoe@,

ssh apollo

Set Up Personal Dotfiles

Git is needed to install my personal dotfiles. While the usual recommended way (like from Github) for Ubuntu is to:

apt-get install git

I'd prefer to install git with Nix Package Manager after being brainwashed by PL. In the ocean of package managers, from brew to macport to pip to anaconda, Nix seems to stand in a league of its own and is superior in many ways. Check out Hacker News' Nix as OS X Package Manager.

curl | sh

Upon Installation finished!, follow the on-screen instruction:

. /home/userjoe/.nix-profile/etc/profile.d/

Search for git on Nix:

nix-env -qa | grep git

Install git (the latest stable release version will be installed automatically):

nix-env -i git

Now, follow my own dotfile workflow to port my Linux configurations to this new server apollo. Run this to refresh:

source .bashrc

Now my server prompt on apollo reads:

~ 22:27 [12] userjoe@apollo $

...which is consistent with every other server environment I use. Peace. You feel me?

This concludes Part 1 of "Setting Up VPS on Linode". In Part 2, I'll lay out steps for:

  • Configure DNS
  • Install Apache
  • Set up Apache's Virtual Host File
  • Configure SSL encryption
  • Set up mySQL
  • How to deploy from local to remote live instance with Gitlab
  • How to deploy wordpress automatically (tricky business...still working through it).
