Error after executing brenda-tool ssh uptime #7

Closed dalekurt closed 10 years ago

dalekurt commented 10 years ago

I have brenda running on an AWS Ec2 instance (Amazon Linux AMI). I executed the command brenda-tool ssh uptime and got the following:

I think the problem is that the AMI you are using has Python 2.6 installed, but 2.7 is required by Brenda because the check_output method of subprocess was only added in Python 2.7. I would advise to use the standard Brenda AMI, as it is known to have the correct versions of dependencies.

Okay, I have an EC2 instance which is the render farm manager. It currently has python 2.6.9 installed on the instance. The instance was launched using the Amazon Linux AMI (t1.micro). I will update python to version 2.7.

What is the AMI ID for the standard brenda AMI?

My plan is to build a web interface for brenda, so this instance will be the render farm manager and host for the web app.

Thanks James, I'm now using the AMI brenda-0.5.3 (ami-0529086c) for launching the render farm manager.

I'm getting the following error when executing brenda-run status

The EC2 instance (manager) that I launched based on the AMI ami-0529086c get terminated along with the other spot instance when I execute brenda-run -T stop

How may I prevent this other than building my own AMI from scratch?

dalekurt commented 10 years ago

I've launched a new AMI (ami-018c9568) and provisioned it for brenda. This EC2 instance has python 2.7 as required by brenda.

Install Dependencies $ sudo apt-get update $ sudo apt-get install git s3cmd python-boto python-dev libcurl4-gnutls-dev

Install Brenda $ git clone http://github.com/jamesyonan/brenda.git $ cd brenda $ sudo python setup.py install

Thanks!
