Amazon Web Service - AWS
Overview
- Create AWS account (free, but requires credit card)
- Create an Ubuntu instance (free, as long as you select the free EC2 variant, and your account is within the "one year free" grace period)
- after 173.678 Instance Hrs, I now owe $2.36 ($0.0116 / instance hr.)
- Install software on Ubuntu instance
Create Amazon Web Services Account and log into account Click on "EC2 Dashboard" Click on "Launch Instance" button, select Ubuntu Server 18.04 LTS Select "General purpose t2.micro Free tier eligible" Click Review and Launch After clicking on "Launch Instances", you will need to define a key pair. Provide a name for this security key pair. A security key-pair file will be downloaded. I used the name "AwsServer" Save it! This is the private key to your instance. Connect to your instance via SSH (I prefer to use TeraTerm for my SSH connection). Within your instance dashboard, for your currently running instance, find the Public DNS (IPv4) address. Example: ec2-18-237-174-213.us-west-2.compute.amazonaws.com - Follow step by step detailed below...
Connect with TeraTerm - Tera Term Download: https://ttssh2.osdn.jp/index.html.en or https://download.cnet.com/Tera-Term/3000-2094_4-75766675.html
- Select TCP/IP
- Check History
- TCP port #: 22
- Service SSH, SSHVersion SSH2
- Click "OK"
- User Name: ubuntu (This is the initial default user name for all Ubuntu instances.)
- Select "Use RSA/DSA/ECDSA/ED25519 key" and select the private key you downloaded earlier (Show all file types)
- Click "OK"
Connect with Putty: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html)
Connect with Linux terminal: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AccessingInstancesLinux.html
The above steps should produce an SSH command prompt for your AWS Linux instance.
Let's perform a couple status checks...
Check available storage
[ec2-user@ip-172-31-27-115 ~]$ df Filesystem 1K-blocks Used Available Use% Mounted on devtmpfs 494152 60 494092 1% /dev tmpfs 504716 0 504716 0% /dev/shm /dev/xvda1 8123812 1101424 6922140 14% /
Check RAM usage
[ec2-user@ip-172-31-27-115 ~]$ free

Common Linux applications already installed in the X86 Ubuntu 18.04 instance
- top
- htop
- vi
- nano
- ps
- lscpu
- lsmod
- ifconfig
- ping
- nano
- screen
- busybox (very few, if any, sym-links to this application)
Any scripting language support? Java: NO Python: Yes version 2.7.18
Compilers? cc: NO, gcc: NO
Common Linux applications already installed in the ARM Ubuntu 18.04 instance
I was expecting differences between the X86 instance and the ARM instance. For the most part, they have been configured rather equally. Everything found in the X86 instance was also found in the ARM instance.
Personalize your instance
Append the following on the end of .bashrc # define current timezone so the date command reports correct local time export TZ=CDT+5
- Install Midnight Commander (mc)
- Install Apache Web Server
- Install Tight VNC Server
$ sudo yum update -y (This will add Python 3.7.9) $ sudo yum install httpd -y
The default document root for Apache is: /var/www/html/ The server is looking for "index.html" to use for the default web page. Rename the current one and replace it with your own: $ cd /var/www/html $ sudo mv index.html index.html.bak $ sudo cp jim.html index.html < This assumes you have a replacement file...
