Place a pound sign (#) before

Place a pound sign (#) before that line. Amazon EC2 might not be the best place to just get started with server administration, because it is fairly technical. I'd recommend starting to work with local Linux / Unix setups first before jumping into EC2.

What do you mean by

What do you mean by "comment out the line" in ( edit /etc/fstab and comment out the line)? Please.

I think this is a great tutorial but some more explanation about editing stuff would be really helpful please. I am learning this and i am finding ec2 a great environment to try stuff out and learn while not destroying a well developed website or db.

Thanks! great instructions.

Thanks! great instructions. One note thought, I needed to do a
sudo apt-get update
before doing
sudo tasksel install lamp-server

Each instance is its own

Each instance is its own virtual machine, so they won't automatically pool resources. You could use some of the load-balancing options to spread this out, but that will require some work on your end.

Generally, the easiest approach would be to clone a new small instance from your existing micro one, then simply switch over the elastic IP to point at this new small instance. You'll get the faster performance of the small instance (which can take quite a bit of load in my testing) while minimizing downtime.

Great tutorial, just what I

Great tutorial, just what I needed!

One thing I couldn't get though... Say you reserve a micro instance which works just fine, but during the workday the load increases, so you'd like to increase the resources a bit.

Can you bring another micro instance into the game for a few hours and have the database use the combined instances' cpu/ram ?

Is that possible? Or you'll need to upgrade to a higher instance type, like Small or use some complex load balancing?

Thanks once again for the useful tut!

It's not a good idea to

It's not a good idea to enable password logins. Don't spread bad practices, please!

You cannot revoke shared access granted via passwords, unless you change the password and notify everyone who knows it.
But this process is tedious and requires the password being transmitted via various channels.
It's not safe for a secret to travel, i hope we can agree on that ;)

With SSH public keys you can grant and revoke access to an account for any number of people and you never have to handle any secret and they can change their corresponding private key passphrase without your knowledge any time and it won't affect their granted access...

I think Transmit can utilize SSH agents.
Just add your key to your agent with the "ssh-add" command, provide your passphrase and Transmit shouldn't ask for anything when you are connecting.
If I'm correct, by default the keys generated by Amazon don't have a passphrase.
It's not very secure, so encrypt your downloaded key with the "ssh-keygen -p" command.

Otherwise thanks for the article. It can help my friend to move his server without too much help from me.

Great tuto. Will do the same

Great tuto. Will do the same with Wordpress ;-)
To send email from EC2 this was a problem. That is why we are using either Gmail as SMTP gateway with a limit of 1000 email per day or external email gateway like authsmtp.com.

But I found really reliable to use an elastic IP address to my instance to let it send email to webmail like Hotmail and Yahoo for example.

Now with the new functionnality of Reverse DNS Proxy of Amazon this can open new way not to be considered as spam when email are sent from Amazon.

It has been my experience

It has been my experience that emails sent from an EC2 instance tend to be blacklisted as spam. This appears to be because a few bad actors seized on EC2 as a spamming platform early, due to its scalability.

I'd highly recommend a solution like MailChimp for mass-mailings over an EC2 SMTP server.
