AWS Experience Part 8: Bundling OpenSolaris

Hi all,

I created the perfect AMI: OpenSolaris with JDK, Ant, MySQl 5 and GlassFish. And then it turns out that OpenSolaris has different directions for bundling than Linux. It took me a while to find them, but I did. Here they are (I'll skip the pre-bundling cleaning up):

  1. Connect to the OpenSolaris instance in the same way as Linux (SSH).
  2. Execute the following commands: cd /mnt and /opt/ec2/sbin/rebundle.sh -v your-bundle.img. Note: of course you can name the bundle whatever you want.
  3. Get some coffee. This could take a while.
  4. Set the following environment variables:
    • export BUCKET=<bucket-name>
    • export JAVA_HOME=/usr/jdk/latest
    • export EC2_HOME=/opt/ec2
    • export PATH=$PATH:$EC2_HOME/bin

AWS Experience Part 7: OpenSolaris AMI

Hi all,

Up until now, I've been working with Fedora AMIs in my quest to master working with virtual servers on AWS. Today I jumped over to an OpenSolaris AMI.

I love it! The pkg command makes things very easy.

So far installing things like Ant, JDK, and MySQL have gone perfectly. I'll write more as I learn.

Cheers!

AWS Experience Part 6: Creating a Custom AMI

Hi all,

Here is another installment on working in the cloud, the AWS cloud that is. Today's topic: creating a custom AMI. This may sound like as easy task. And it would have been, had AWS documentation been up to scratch. I spent lots of time messing around with this, and I finally got it to work. Here's how:

  1. Launch an exiting image (I chose a Fedora 8 image). Modify the /var/www/html/index.html file to something else (thus making it "your unique AMI). I went one step further: I installed JDK 6 and MySQL on mi AMI for use at a later date.
  2. Now you have to upload your private key and x509 certificate to the AMI. Here's how to do this in the terminal:
    scp -i ~/.ssh/<yourkeypair.pem> ~/.ec2/<pk-whatever.pem> ~/.ec2/<cert-whatever.pem> root@your-public-DNS:/mnt.
    
    The private key and x-509 certificate should be uploaded to the mnt directory to prevent them from being bundled with the …

SQL Editor and NetBeans | #1

In the previous blog, I mentioned SQL Editor. NetBeans has improved it in every release in the past 2 years and it looks great these days. Here’s a sneak-peek;

This figure shows the SQL Editor window along with the results shown for the command executed, written in the editor (select * from nbusers). Also, you can see numerous toolbar buttons, and results are shown in similar way as if it was any CRUD application. We will discuss this in more detail in following section and follow-up blogs.

Key Features..

To execute any SQL query within the …

MySQL, NetBeans and SQL Editor

I have been busy lately thanks to my internship project, which almost got screwed up. I was working in a team of 4 people, where we were building a web application, that was initially deployed at JBoss Server using JBoss Eclipse IDE (old version). Also, we had to interact with the centralized Oracle Server to setup our database for running the website.

Now, having being trained on some of those technologies in past few months, I thought it won’t be much of an issue. However, at the beginning of this month, I faced some weird issues which had no obvious answers. There weren’t any silly mistakes either. We were facing some issues with Oracle connectivity. I am not blaming Oracle or the company where we did the project. But, mix of old and new technologies, turned out to be quite confusing resulting in lot of trouble.

We were running out of time, so we decided to migrate our database to MySQL Server and use NetBeans 6.5 IDE, …

AWS Experience Part 3: Trying Another Instance

Hi all,

Hmmmm...

I switched on my machine this morning thinking a new day will bring new results. Nope. Same old results. As I mentioned in an earlier blog entry, I created a server instance using Fedora with LAMP, complete with MySQL. Hmmm.. Sound good? Well, it comes with MySQL 4.1. Normally an update would be a straightforward process. Since Fedora 8 doesn't come with an

apt-get

command, I chose to go the

yum

route. I tried

 yum update mysql-server

. No dice. problems. I spent another 30 minutes or so, trying to correct the problem, but to no avail. So I decided to create a whole new server instance with Fedora 8 and no MySQL. I manually installed MySQL on the machine, by doing the following:

  • I download the MySQL sever, cient, and headers and libraries from the MySQL.com.
    wget …

AWS Experience Part 2: Accessing the Cloud

Hi all,

Today I'll be write more about my experiences with Amazon Web Services. Before I continue, I'd like to provide some background information.

I signed up for Amazon Web Services. I used the Fedora LAMP AMI to create a server instance. The main reason for choosing this AMI was its inclusion of MySQL and Apache, a nice little package indeed. I ran into a few problems at first. Because I am based in Europe, I am allowed to use only the EU-West region, and the default in the US-East region. The drop down list is rather small, and i took a couple of unsuccessful instances to figure out that this was the problem. When I say "unsuccessful instances," I mean that the nothing appeared in the browser when I copied the public DNS to the browser's address bar. I attached an EBS volume to the server instance and it was OK.

Now for more on the command line.

I spent a lot of time messing around with the commands in the …
