Running an AMI
How to register an AMI
The AMI must be registered with Amazon EC2 in order to run instances, to do this run the following command:
# ec2-register bashlinux/bashlinux-general-server.fs.manifest.xml
then the AMI will be registered and the command will yield the name assigned, for this case the name is:
IMAGE ami-43ab4f2a
If you cannot see the AMI name, you can try to run the following command
# ec2-describe-images -o self
and it will return a string with the details of each AMI into the bashlinux bucket
IMAGE ami-43ab4f2a bashlinux/bashlinux-general-server.fs.manifest.xml 367161194499 available private i386machine
How to generate a Keypair
One half of this keypair will be embedded into the instance created, allowing you to login securely without a password using the other half of the keypair. Every keypair need a name, so we can use the name of the image and run the following command:
# ec2-add-keypair bashlinux-general-server-keypair KEYPAIR bashlinux-general-server-keypair 2c:34:d7:d0:44:c5:06:07:3e:36:d3:99:9e:69:f2:5c:2f:ed:ab:47 -----BEGIN RSA PRIVATE KEY----- MIIEpAIBAAKCAQEAmJ7Sl4k3FSXFHcpV0bluEcUcRXaOHEn+w3+zmnKe/dcbRh2lq+mYubQQl8hg xmbPbD70gW8PxIqoG7FJwy4cEQhibuAyC5Fl9AsGetaC91fyoIA/veNuj+abIWiYHtrp9yGKZjRo ... ... ... 0OYLdAavg5dV9ftW9a/5hk01+iscqp5N30SJIwgOYDWDPJwdztLjTuqdfFVg2VpKswb/8SnsOb9v OV/fvQHp+KxP6Ppjpxd1a7amAF2Kq+UMozXW9/iSZSKkVHiHwQjeLklFm5WOtpoW5OxvRQ== -----END RSA PRIVATE KEY-----
then we create a file ~/.ssh/bashlinux-general-server-keypair and paste everything between (and including) the lines
-----BEGIN RSA PRIVATE KEY-----
and
-----END RSA PRIVATE KEY-----
To finish change permissions to the file
# chmod 600 ~/.ssh/bashlinux-general-server-keypair
How to run an instance
The command to launch an instance is
# ec2-run-instances ami-43ab4f2a -k ~/.ssh/bashlinux-general-server-keypair RESERVATION r-075c9f6e 367161194499 default INSTANCE i-ef79ad86 ami-43ab4f2a pending 0 m1.small 2008-06-20T01:36:56+0000 us-east-1b
Then to check the status run:
# ec2-describe-instances i-577aae3e RESERVATION r-9f5c9ff6 367161194499 default INSTANCE i-577aae3e ami-43ab4f2a ec2-67-202-23-7.compute-1.amazonaws.com domU-12-31-39-00-A2-02.compute-1 .internal running bashlinux-general-server-keypair 0 m1.small 2008-06-20T01:57:42+0000 us-east-1a
where the name is ec2-67-202-23-7.compute-1.amazonaws.com
How to authorize network access to the instances
Now that the image is running we need to authorize network traffic to the instance, run the following commands to accomplish with:
# ec2-authorize default -p 22 GROUP default PERMISSION default ALLOWS tcp 22 22 FROM CIDR 0.0.0.0/0 # ec2-authorize default -p 80 GROUP default PERMISSION default ALLOWS tcp 80 80 FROM CIDR 0.0.0.0/0
How to connect to the launched instance
Now that network is authorized you can connect using the following command:
ssh -i bashlinux-general-server-keypair [email protected]
How to link a public IP address to the instance
Allocating IP address
Now that the instance is running it only has a private IP, in order to allocate an public IP address run the following command:
# ec2-allocate-address ADDRESS 75.101.129.154
Associating IP address
The IP address the gave us the above command must be added to the associate command as follows:
# ec2-associate-address -i i-577aae3e 75.101.129.154 ADDRESS 75.101.129.154 i-577aae3e
The instance can be now accessed typing in the browser ec2-75-101-129-154.compute-1.amazonaws.com
