How to ssh into aws ec2？

[emerisly]

1. Just ssh (easy but less convenient for long-term usage)

Ask Emerald, Felix, or Zander for the certificate file "mathsearch-backend.pem".
Do not give this file to others or upload it GitHub.
Put pem file under the dir you want to work in, cd into that dir.
Change pem file security by running chmod 600 mathsearch-backend.pem.
Now we are ready to ssh into ec2, run ssh -i "mathsearch-backend.pem" [email protected].

2. Recommend method with vscode

cd into .ssh dir with cd ~/.ssh command.
Put pem file under this dir and run chmod 600 mathsearch-backend.pem.
Edit file ~/.ssh/config by adding below few lines. This adds ssh permission so your vscode can recognize.

# aws
Host ec2-18-207-249-45.compute-1.amazonaws.com
   HostName ec2-18-207-249-45.compute-1.amazonaws.com
   User ubuntu
   IdentityFile ~/.ssh/mathsearch-backend.pem

Open vscode, make sure you have remote-ssh extension, do "Remote SSH: Connect to Host" and select our was.
On the left, you can select folder path to show in explorer.
