Root access amazon ec2

amazon ec2root

Hey guys, I am very new to linux, and amazon-ec2. I wanted to put a quick server.
For some reason, when I sign in with my key pair, it prompts me for a username, I input ec2-user, and I'm in.
The problem is that I don't have root access (and can't find the root password).
I need to install screen to run the server in the background, and also create a new user, that doesn't have root, to run the server. Neither of which I can do without root..
Any help?

Edit:
I am using Basic 32-bit Amazon Linux AMI 2010.11.1 Beta as the 'AMI'.

Thanks,
Max

The Amazon Linux AMI User Guide explains that you can use sudo to run commands as root e.g. sudo whoami:

How do I get root SSH access on my Amazon Linux AMI instance?

The Amazon Linux AMI does not allow remote root SSH by default. You should specify a keypair at instance launch and login as ‘ec2‐user’ using your keypair to access the command line. This user has sudo access by default to allow you to run root actions. If you wish to enable remote root login, please be aware that it is significantly less secure than relying on keypairs and a secondary user.

Install vsFTPD Server from yum repository

sudo yum install vsftpd -y
Configure Basic Settings for vsFTPD server

sudo vi /etc/vsftpd/vsftpd.conf

a. Make the below changes in the file and save i. Disable anonymous users anonymous_enable=NO ii. Allow local users, meaning that vsFTPD server will use Linux system users and authentication to determine who can sign in local_enable=YES iii. Allow local users WRITE access, so that they can upload material and modify content write_enable=YES iv. Confine users to the respective home directories chroot_local_user=YES v. Basic vsFTPD related changes pasv_enable=YES pasv_min_port=1024 pasv_max_port=1048 pasv_address=
Create an FTP User

sudo adduser ftpuser
Assign a password to the new user

sudo passwd ftpuser

Configure SSL with vsFTPD server a. Create a sub directory to store the files # sudo mkdir /etc/ssl/private

b. Create the certificate and the key in a single file # sudo openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout /etc/ssl/private/vsftpd.pem -out /etc/ssl/private/vsftpd.pem

c. Add the SSL Details to the vsftpd Configuration File # sudo vi /etc/vsftpd/vsftpd.conf

i. Specify the location of the certificate and key files
    rsa_cert_file=/etc/ssl/private/vsftpd.pem
    rsa_private_key_file=/etc/ssl/private/vsftpd.pem

ii. Enable the use of the files, disable anonymous users and force the use of SSL for both data transfer and login routines
    ssl_enable=YES
    allow_anon_ssl=NO
    force_local_data_ssl=YES
    force_local_logins_ssl=YES

iii. Restrict the type of connection to TLS, which is more secure than SSL
    ssl_tlsv1=YES
    ssl_sslv2=NO
    ssl_sslv3=NO
    require_ssl_reuse=NO
    ssl_ciphers=HIGH
