### Install
|
|
|
|
$ sudo apt-get install ec2-api-tools ec2-ami-tools
|
|
$ brew install ec2-api-tools ec2-ami-tools
|
|
|
|
### Pem files
|
|
|
|
$ brew info ec2-api-tools
|
|
|
|
* Before you can use these tools you must export some variables to your $SHELL
|
|
and download your X.509 certificate and private key from Amazon Web Services.
|
|
|
|
* Your certificate and private key are available at
|
|
[aws-portal.amazon.com](http://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key).
|
|
|
|
* Download two `.pem` files, one starting with `pk-`, and one starting with `cert-`.
|
|
You need to put both into a folder in your home directory, `~/.ec2`.
|
|
|
|
### Key pair
|
|
|
|
# To use public images (AMI's), you need an SSH keypair from EC2.
|
|
ec2-add-keypair my-keypair > ~/.ec2/my-keypair.pem
|
|
chmod 600 ec2-keypair.pem
|
|
|
|
### Start an instance
|
|
|
|
# Start an instance using a given AMI image:
|
|
# (Use the Ubuntu locator, or ec2-describe-images)
|
|
ec2-run-instances ami-xxxxxx -k ec2-keypair
|
|
|
|
# Open up ports (in the 'default' security group):
|
|
ec2-authorize default -p 22
|
|
ec2-authorize default -p 80
|
|
|
|
# Connect
|
|
ssh -i ~/.ec2/my-keypair.pem root@ec2-xxx.amazonaws.com
|
|
|
|
### Management
|
|
|
|
# Show running instances
|
|
ec2-describe-instances
|
|
|
|
# Kill an instance
|
|
ec2-terminate-instances i-yourinstance
|
|
|
|
### Misc
|
|
|
|
# Create a security group
|
|
ec2-add-group group_name -d "Description"
|
|
|
|
# Show images (AMI's) owned by amazon, or me
|
|
ec2-describe-images -o self -o amazon
|
|
|
|
### Ubuntu images
|
|
|
|
* [Ubuntu EC2 AMI locator](http://cloud-images.ubuntu.com/locator/ec2/)
|
|
|
|
### Change certificates
|
|
|
|
EC2_CERT_PATH="$HOME/.ec2"
|
|
export EC2_PRIVATE_KEY="$(/bin/ls $EC2_CERT_PATH/pk-*.pem | /usr/bin/head -1)"
|
|
export EC2_CERT="$(/bin/ls $EC2_CERT_PATH/cert-*.pem | /usr/bin/head -1)"
