= Running an AMI =

== Registering the AMI ==
The AMI must be registered with Amazon EC2 in order to run instances, to do this run the following command:
<pre><nowiki>
# ec2-register bashlinux/bashlinux-general-server.fs.manifest.xml
</nowiki></pre>

then the AMI will be registered and the command will yield the name assigned, for this case the name is:
<pre><nowiki>
IMAGE ami-43ab4f2a
</nowiki></pre>

If you cannot see the AMI name, you can try to run the following command
<pre><nowiki>
# ec2-describe-images -o self
</nowiki></pre>

and it will return a string with the details of each AMI into the ''bashlinux'' bucket
<pre><nowiki>
IMAGE ami-43ab4f2a bashlinux/bashlinux-general-server.fs.manifest.xml 367161194499 available private i386machine
</nowiki></pre>


== Generating 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 fullowing command:
<pre><nowiki>
# 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

-----END RSA PRIVATE KEY-----
</nowiki></pre>

then we create a file called `~/.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
<pre><nowiki>
# chmod 600 ~/.ssh/bashlinux-general-server-keypair
</nowiki></pre>


== Running an instance ==
The command to launch an instance is
<pre><nowiki>
# 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
</nowiki></pre>

Then to check the status run:
<pre><nowiki>
# 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
</nowiki></pre>

where the name is `ec2-67-202-23-7.compute-1.amazonaws.com`.

=== Authorizing 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:
<pre><nowiki>
# 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
</nowiki></pre>


=== Connect to the launched instance ===
Now that network is authorized you can connect using the following command:
<pre><nowiki>
ssh -i bashlinux-general-server-keypair [email protected]
</nowiki></pre>


=== Link 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:
<pre><nowiki>
# ec2-allocate-address
ADDRESS 75.101.129.154
</nowiki></pre>

'''Associating IP address'''
The IP address the gave us the above command must be added to the associate command as follows:
<pre><nowiki>
# ec2-associate-address -i i-577aae3e 75.101.129.154
ADDRESS 75.101.129.154 i-577aae3e
</nowiki></pre>

The instance can be now accessed typing in the browser `ec2-75-101-129-154.compute-1.amazonaws.com`
