INFO:

EC2 from Amazon stands for "Elastic Compute Cloud", and is a core component of their cloud based computing services collectively know as Amazon Web Services (AWS).

NOTE: In the following tutorial replace <yourdomain.com> with your own domain name.

Volumes

Volumes are hard disk drives. They can be attached to a running virtual machine (just like plugging the cables in), and then have to be partitioned, formatted and mounted.

EBS

EBS is Elastic Block Storage and basically means that Amazon use a whole bunch of drives stored over several servers and then put those together to make your disk or volume. After a volume is attached to an instance, you can use it like any other physical hard drive. EBS volumes persist independently from the running life of an EC2 instance. This is just like having a physical hard drive, unplugging it and keeping the data on it. When you create an EBS volume in an Availability Zone, it is automatically replicated within that zone to prevent data loss due to failure of any single hardware component. After you create a volume, you can attach it to any EC2 instance in the same Availability Zone. After you attach a volume, it appears as a native block device similar to a hard drive or other physical device. At that point, the instance can interact with the volume just as it would with a local drive.

EFS

EFS is Elastic File Storage and is basically NFS or a network drive. To use it, you have to mount it in the operating system.

Create New Volume From Snapshot

1. Create a new volume from the backup snapshot by using the following command: 

ec2-create-volume –z us-west-1b –snapshot MySnapshotName

2. Within the Amazon EC2 instance, unmount the existing volume (e.g., by using umount in Linux or the Logical Volume Manager in Windows). 3. Detach the existing volume from the instance by using the following command: 

ec2-detach-volume OldVolume

4. Attach the new volume that was created from the snapshot by using the following command: 

ec2-attach-volume VolumeID –I InstanceID –d Device

5. Remount the volume on the running instance.

Security Groups / Firewall

Add Rule

Dynamic My IP... 

aws ec2 authorize-security-group-ingress --group-name launch-wizard-1 --protocol tcp --port 993 --cidr `curl --silent http://checkip.dyndns.com | grep -o --color=never -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'`/32

IMAPS... 

aws ec2 authorize-security-group-ingress --group-name imaps --protocol tcp --port 993 --cidr `curl --silent http://checkip.dyndns.com | grep -o --color=never -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'`/32

Or manually... 

aws ec2 authorize-security-group-ingress --group-name launch-wizard-1 --protocol tcp --port 993 --cidr 123.456.789.10/32

TCP ports 80 and 443 from anywhere on rule group launch-wizard-3... 

aws ec2 authorize-security-group-ingress --group-name launch-wizard-3 --protocol tcp --port 80 --cidr 0.0.0.0/32
aws ec2 authorize-security-group-ingress --group-name launch-wizard-3 --protocol tcp --port 443 --cidr 0.0.0.0/32

Delete Rule

aws ec2 revoke-security-group-ingress --group-name launch-wizard-1 --protocol tcp --port 993 --cidr 123.456.789.10/32

aws ec2 revoke-security-group-ingress --group-name launch-wizard-3 --protocol tcp --port 80 --cidr 0.0.0.0/32
aws ec2 revoke-security-group-ingress --group-name launch-wizard-3 --protocol tcp --port 443 --cidr 0.0.0.0/32

Check Rules

aws --profile default ec2 describe-security-groups --group-names launch-wizard-3

Increase EBS Volume Size

https://docs.aws.amazon.com/ebs/latest/userguide/recognize-expanded-volume-linux.html

This is easeiest if you log in to the instance and do the commands there, because you can then Extend the file system after resizing an EBS volume.

Switch to root user... 

sudo -i

Find instance id of this host... 

wget -q -O - http://169.254.169.254/latest/meta-data/instance-id
ec2metadata --instance-id

Find volume ID and GB size of disk... 

aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=`ec2metadata --instance-id` --query "Volumes[*].{ID:VolumeId,Size:Size}"

Increase the disk size... 

aws ec2 modify-volume --volume-id vol-XXXXXXXXXXXXX --size <gbsize>

Check the modification.. 

aws ec2 describe-volumes-modifications --volume-ids vol-XXXXXXXXXXXXX

As it is processing, the state changes through modifying and optimizing.

Confirm that the volume modification succeeded and that it is in the completed or in-use state.

Check the disk to show partition name and actual size and current partition usage. For example, xvda1 and 10G and 7G... 

lsblk
xvda     202:0    0   10G  0 disk 
├─xvda1  202:1    0    7G  0 part /

Increase the partition size... 

growpart /dev/xvda 1       (<-- older disks)
growpart /dev/nvme0n1 1    (<-- newer disks)

Check again... 

lsblk
xvda     202:0    0   10G  0 disk 
├─xvda1  202:1    0    9G  0 part /

Find out what Linux filesystem you are using... 

df -H -T /

Expand the ext4 filesystem... 

resize2fs /dev/xvda1       (<-- older disks)
resize2fs /dev/nvme0n1p1   (<-- newer disks)

Expand the xfs filesystem... 

xfs_growfs -d /

Reboot the instance... 

reboot

CLI Query Examples

Launch Templates

aws ec2 modify-launch-template --launch-template-id "lt-0e4c99bf82b0d2623" --default-version "9" --region "eu-west-2"

HOWTO: Increase Disk Size

NEW

  1. stop instance
  2. create snapshot
  3. increase volume size
  4. wait for volume state to go through 'resizing' 'optimising' and then 'complete'
  5. start instance

OLD

sudo -i
growpart /dev/xvda 1
resize2fs /dev/xvda1
reboot

FIX NO SPACE LEFT ON DEVICE

  1. ssh in to vm
  2. switch to root
  3. uname -a to find out which kernel is being used
  4. rm -rfv /boot/*kernel-version*
  5. repeat to remove all but current kernel
  6. apt-get autoclean
  7. apt-get clean

HOWTO: TAKE SCREENSHOT

How to Take a Screenshot of an Unreachable Instance

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
  2. In the left navigation pane, choose Instances.
  3. Select the instance to capture.
  4. Choose Actions, Instance Settings.
  5. Choose Get Instance Screenshot.

HOWTO: ADD TO SECURITY GROUPS

Allow PING

By default EC2 will add a ping rule based on the IP address you are using when you create an machine instance, so to ping from a different IP address you will need to create another rule. 

EC2 Dashboard > Network & Security > Security Groups > Select the desired Group ID > Inbound (tab) > / 
                Edit > Add Rule > (Type) Custom ICMP Rule > (Protocol) Echo Request > (Source) Custom IP > Save

Allow HTTP & HTTPS Ports

Separate rules are required for both protocols. 

EC2 Dashboard > Network & Security > Security Groups > Select the desired Group ID > Inbound (tab) > /
                Edit > Add Rule > (Type) TCP > Source (Anywhere, for the entire world) > Save

Additional SSH Locations

By default EC2 will add a SSH login rule based on the IP address you are using when you create an machine instance, so to log in via a different IP address you will need to create another rule. 

EC2 Dashboard > Network & Security > Security Groups > Select the desired Group ID > Inbound (tab) > / 
                Edit > Add Rule > (Type) SSH > (Source) Either "My IP" or "Custom IP" (best not to use the "Anywhere" option) > Save

HOWTO: ELASTIC IP REVERSE DNS

A reverse Domain Name System (DNS) lookup is used by email servers to track where a message originated from, and confirm that it's not spam or malicious. A reverse DNS lookup returns the domain name of an IP address. This is in contrast to a forward DNS lookup, which returns the IP address of a domain.

HOWTO: ADD SWAP FILE

You can add a 512MB swap to your instance with these commands: 

sudo dd if=/dev/zero of=/swapfile bs=1M count=512
sudo chmod 0600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

To enable it by default after reboot, add this line to /etc/fstab: 

/swapfile swap swap defaults 0 0

HOWTO: INCREASE RAM OR CPU

http://aws.amazon.com/ec2/instance-types

NEW METHOD

  1. Instances > Select Instance > Actions > Instance State > Stop
  2. Instances > Select Instance > Actions > Instance Settings > Change Instance Type > Configure > Review > Change

OLD METHOD

Unfortunately, there is no easy way to increase the RAM in a running instance. You have to create a copy of the instance, launch a new instance based on the copy but with more RAM, associate the Elastic IP address with your new instance, then stop your old instance.

  1. Instances > Select Instance > Actions > Instance State > Stop
  2. Instances > Select Instance > Actions > Image > Bundle Image (AMI) > Name > Save Image
  3. Instances > Launch Instance > My AMIs > Select > Configure > Review > Start
  4. Instances > Select NEW Instance > Note ID
  5. Elastic IPs > Select Elastic IP > Actions > Associate Address > NEW Instance ID > Associate
  6. Instances > Select NEW Instance > Actions > Connect > SSH > Check RAM
  7. Instances > Select OLD Instance > Actions > Instance State > Stop
