MySQL on EBS with OpenSolaris based AMI

Amazon Elastic Block Store (EBS) is the persistent storage which can be attached to the AMI instance. Data can be safely placed and accessed independent of the life of the instance. There are plenty of benefits using EBS for MySQL. For detailed explanation click here.



Following steps describes how to use MySQL on EBS volume with OpenSolaris based AMI.

1. Create a new EBS Volume.

$ ec2-create-volume --size 10 --availability-zone us-east-1a
VOLUME    vol-688d4c01    10        us-east-1a    creating    2010-01-13T21:54:57+0000

$ ec2-describe-volumes vol-688d4c01
VOLUME    vol-688d4c01    10        us-east-1a    available    2010-01-13T21:54:57+0000

Click here for ec2-create-volume API help.

2. Create a new MySQL 5.1 AMI Instance based on OpenSolaris.

$ ec2-run-instances ami-752ccb1c -k my-keypair
RESERVATION    r-2486124c    987654321123    default
INSTANCE    i-9e6858f6    ami-752ccb1c            pending    my-keypair    0        m1.small    2010-01-17T00:01:24+0000    us-east-1a    aki-6552b60c    ari-6452b60d        monitoring-disabled

Click here for more details on this AMI.

3. Attach EBS volume to this AMI instance

$ ec2-attach-volume -i i-9e6858f6 -d 2 vol-688d4c01
ATTACHMENT    vol-688d4c01    i-9e6858f6    2    attaching    2010-01-13T22:02:51+0000

In the above command -d option specifies the device number. In OpenSolaris devices are named from 0 to 23. Device number 0 and 1 are used for ephemeral storage. Therefore, we can use the devices starting from 2 until 23.

$ ec2-describe-volumes vol-688d4c01
VOLUME    vol-688d4c01    10        us-east-1a    in-use    2010-01-13T21:54:57+0000
ATTACHMENT    vol-688d4c01    i-9e6858f6    2    attached    2010-01-13T22:02:51+0000

4. Create a ZFS storage pool on the previously attached EBS volume.

Once the instance is up and running, login into the instance using ssh with your key-pair.
To verify new EBS volume attached, execute the format command and press Control + C to come out.

Connecting MySQL server on Amazon EC2 instance using ssh tunnel

SSH tunnel basically does the port forwarding via secure ssh service.

Let's start with launching a latest hardened AMP stack AMI (ami-e0b05389) instance.
Once the instnace is up and running, open the terminal client and connect to the instance using ssh.

Edit the /etc/ssh/sshd_config file and set AllowTcpForwarding to yes
AllowTcpForwarding yes

Restart ssh service
svcadm restart svc:/network/ssh:default

Comment out skip-networking from /etc/mysql/my.cnf and save the file
#skip-networking

Restart MySQL service
svcadm restart svc:/application/database/mysql:version_51

exit the ssh connection and recreate ssh connection using following command.
ssh -i <keypair> -L 3307:localhost:3306 root@ec2-xxx-xxx-xxx-xx.compute-1.amazonaws.com

Keep the terminal opened, and start MySQL Query Browser / MySQL administrator from your local machine. and  connect to the MySQL server on remote EC2 instance via the port 3307, as shown in the following sanpshots.


When done close the ssh connection and it should close the ssh tunnel.

How to Setup iPhone AWS manager on OpenSolaris EC2 Instance


Project Link: http://code.google.com/p/iphone-aws-manager/

I was looking for the free iPhone application to manage my ec2 account and came across this article: "Mobile Monitoring and Administration of Amazon Web Services: Developing an iPhone-Optimized Web Application".

This article not only describes in details each steps on how to begin with developing iPhone application to manage AWS but also provides source code that you easily download from Google Code Repository and setup in-house.

In this blog entry I will walk you through steps on setting up this application on our popular OpenSolaris AMP Stack AMI.

Following Steps are also valid for the setup of "iPhone AWS Manager" on local machine with OpenSolaris and AMP Stack.

Lets begin with launching new OpenSolaris AMP Stack AMI Instance.
ec2-run-instances ami-c7cf28ae -k my-keypair

Get the public DNS address of an Instance and login into with your keypair
ec2-describe-instances i-xxxxxxxx
ssh -i <path_to_your_keypair> root@ec2-xx-xxx-xx-xxx.compute-1.amazonaws.com

Install SVN Package from the Repository

Importing OpenSolaris EC2 Image on Local Xen Environment


In this blog entry, I am going to walk you through the steps for importing OpenSolaris Amazon EC2 AMI on local Xen environment running on OpenSolaris 2008.11.

I assume
- you are running OpenSolaris 2008.11 build rc2 dom0.
- ec2 ami/api tools installed at /opt/ec2
- your ec2 certificate and private key files available at /opt/ec2/keys
- your ec2 keypair file located at /opt/ec2



[ Step-1 ]
Launch fresh OpenSolaris 2008.11 AMI Instance
ec2-run-instances ami-7db75014 -k your-keypair

Login in with your keypair file
ssh -i /opt/ec2/your-keypair root@ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com

[ Step-2 ]
Remove EC2 specific stuff from the instance.

Open “/etc/ssh/sshd_config” and replace "PermitRootLogin without-password" with "PermitRootLogin yes" and save the file.

Set the root password
passwd
passwd: Changing password for root
New Password:
Re-enter new Password:
passwd: password successfully changed for root

Disable and remove ec2 specific services

svcadm disable svc:/ec2/sshkey:default
svcadm disable svc:/ec2/fixes:default
svcadm disable svc:/ec2/mount:default

svccfg delete svc:/ec2/sshkey:default
svccfg delete svc:/ec2/fixes:default
svccfg delete svc:/ec2/mount:default

[ Step-3 ]
Log out of the ec2 instance and transfer your keys at /mnt/keys to begin re-bundling image.
scp -i /opt/ec2/id-your-keypair -r /opt/ec2/keys/ root@ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com:/mnt

[ Step-4 ]
Login back to ec2 instance.
ssh -i /opt/ec2/your-keypair root@ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com

[ Step-5 ]
Start bundling the image.

# cd /mnt
# /opt/ec2/sbin/rebundle.sh -v opensolaris_2008_11_ami.img
Creating image file /mnt/opensolaris_2008_11_ami.img
Preparing clone pool on /dev/lofi/1
Cloning
#

rebundle.sh will take about 10-15 minutes to create raw opensolaris image.

[ Step-6 ]
Bundle image and create parts.

export BUCKET=my-bucket
export JAVA_HOME=/usr/jdk/latest
export EC2_HOME=/opt/ec2
export PATH=$PATH:$EC2_HOME/bin
export RUBYLIB=$EC2_HOME/lib
export EC2_URL=https://ec2.amazonaws.com

export EC2_PRIVATE_KEY=/mnt/keys/pk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.pem
export EC2_CERT=/mnt/keys/cert-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.pem

export EC2_KEYID=xxxxxxxxxxxxxxxxxxxxxxx
export EC2_KEY="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

export DIRECTORY=/mnt
export IMAGE=opensolaris_2008_11_ami.img

# ec2-bundle-image -c $EC2_CERT -k $EC2_PRIVATE_KEY \\
--kernel aki-6552b60c --ramdisk ari-6452b60d \\
--block-device-mapping "root=rpool/52@0,ami=0,ephemeral0=1" \\
--user <user-id> --arch i386 \\
-i $DIRECTORY/$IMAGE -d $DIRECTORY/parts

[ Step-7 ]
