Hi,

I am currently writing a unix script for my ec2 instance and I am trying to figure how to make a file transfer from my repository online into the ec2 instance.

What i have so far (or know) is to try:

scp -i http://is/this/the/right/way/to/do/it? ec2@....blah.blah

does this sound right?

Essentially, I want to download those files from my maven repo and upload them to my ec2 machine and then if there are any updates, i have jboss in the script as well to make it update the ec2 instance.

ANY HELP IS APPRECIATED! THANK YOU IN ADVANCED!!

I normally just type in a password or use a set of stored credentials, so I've never used the "-i" option, but the man page says "file", not "url", so I doubt that will work.

My usage is as follows:



So, if I'm using the same userID on both systems and copying to my remote home directory, this degenerates to:


For an absolute location:

Heres an update Tom and thanks for replying. Maybe you can help me with this problem now. Any help is appreciated, thank you!

So I am testing out my UNIX script that I wrote for an instance so it can already have the pre-configured packages and httpd service start. When I input the data in the desired field
"User Data:", it doesn't work. I've tried inputting my Unix code as either a text or a file and neither has worked for me.

This is essentially the script I am writing for the instance(below) and will be more complicated as I incorporate downloading war files from Maven and Jboss.

Admins/top users: Do you see the problem here? When I run these commands manually in Mindterm, it executes perfectly, but when I put it in the "User Data" field it doesn't execute anything. Please help me resolve this. Thanks in advance! Also, this is for the Amazon Linux AMI 2013.03.1 64-bit

Script:

sudo yum update

sudo su

sudo yum -y install httpd mysql mysql-server tomcat* java* apache* git

sudo chkconfig httpd on
/etc/init.d/httpd start

wget http://download.jboss.org/jbossas/7.0/jboss-as-7.0.2.Final/jboss-as-web-7.0.2.Final.tar.gz
tar xvfz jboss-as-web-7.0.2.Final.tar.gz
wget http://www.poolsaboveground.com/apache/maven/maven-2/2.2.1/binaries/apache-maven-2.2.1-bin.tar.gz
tar xvfz apache-maven-2.2.1-bin.tar.gz

sudo yum -y update

echo "script is finished"
echo

I'm not sure I really understood that, but I'll pretty much guarantee that you can't run an init script (/etc/init.d/http start) properly unless you're privileged (sudo).

Speaking of sudo, you can do "sudo -s" and it will switch you to persistent sudo state until you exit it so you can do stuff like this:



For more info, "man sudo".

I agree those commands word(mine do too), but maybe you may have missed my question.

The script or basic layout that I have provided in my previous post all work perfectly when running manually. I did change my sudo su to sudo -s to see if it made any changes. But my main issue and question is: why isnt my script executing when I input it in the user data field when launching my instance for amazon web services. I am not sure if you are familiar with that or not, but I hope you can help me figure this out.

Thanks in advance, Tim.
