Steps to launch AWS instances

• Log in to AWS console

  • Log in to https://awsed.ucsd.edu/.
  • You should see a list of classes, select “CSE291_SP18_C00”.
  • If you are asked to select a role, you should select “CSE291_SP18_C00_student”; otherwise, you should be in AWS console.
  • You should see something like this once you are logged in to AWS console.

• Launch AWS instance

  • Click the blue “Launch Instance” button.
  • Step 1: Choose an Amazon Machine Image (AMI): Choose the first one in the list “Amazon Linux AMI 2018.03.0 (HVM), SSD Volume Type”
  • Step 2: Choose an Instance Type: Keep the default “t2.micro” type, then click next.
  • Step 3 through step 5: you don’t need to change the settings; simply click next.
  • Step 6: Configure Security Group: You need to select an existing security group and choose sg-b3b4e1cd cse124/291c-sp18 UCSD CSE 124/291C SP18 HW3 Security Group. This will open up SSH access (TCP port 22) as well as TCP and UDP ports 8000 to 9000, which you can use for RPC.
  • Step 7: Review Instance Launch: Simply click “Launch” to start your new instance. You will see a warning saying “Improve your instances’ security. Your security group, cse124/291c-sp18, is open to the world.”, but that’s intentional.
  • Now you will see a popup diaglog asking you to “Select an existing key pair or create a new key pair”. This will be the SSH key you’ll use later to connect to the VM. Note that you will only be able to download it once.
    • If this is the first instance you are launching, then you need to choose “Create a new key pair”, choose a meaningful name like “cse291c-hw2-userid-region” and download it.
  • After you successfully launch the instace, you can click the instance id or go back to AWS console. You should be able to see the instance in the list.

• Switch Region

  • For this assignment, you need to create VMs in the following regions:
    • Seoul
    • Ireland
    • Sao Paulo
    • Mumbai
  • To switch region, click the middle dropdown menu in the upper right corner, which shows the current region and defaults to Oregon, and then click the new region.
  • You will need to repeat the “Launch AWS Instance” steps above.

• Connect to the VM

  • You need the following to SSH into your VM:
    • The key pair downloaded from AWS console, e.g. cse291c-hw2-yig004-oregon.pem
    • The instance public DNS or public IP, which you can find out in instance details, e.g. ec2-34-217-75-133.us-west-2.compute.amazonaws.com or 34.217.75.133
  • You might need to change the permissions of your key file so SSH client doesn’t warn you (something like “WARNING: UNPROTECTED PRIVATE KEY FILE!“). To fix this warning, change the permission of the file to 0400 (readable by user only):

  chmod 400 .ssh/cse291c-hw2-yig004-oregon.pem * You can run the following command to SSH into your VM, assuming your key pair file (i.e. .pem file) is in .ssh directory:

  ssh -i .ssh/cse291c-hw2-yig004-oregon.pem [email protected]

  Be sure to replace the key file name and the DNS name with yours.

• Stop your VM

  • When you are done with your experiments, please stop (shut down) them to save costs. Each student is allocated a fixed amount of credit and keeping the VMs running will cost money.
  • To stop the VM, select the instance(s) in the list, and click “Actions” -> “Instance State” -> “Stop”.
  • You do not need to terminate the VM, and you are not allowed to do so as configured by ACMS.
