Amazon Web Services (AWS) technical details
class="active"

Semi-structured list of technical details of working with Amazon Web Services (AWS). This is a holding page for some technical incantations required to use the system.

Userids

  • Distinguish the account id, any IAM ids, your public/private key pair for SSH to any EC2 instances, and your access key/private key pair.

EC2 instances

  • Connecting to an instance: ssh -i <keyfile> ec2-user@<public IP for your machine>, where <keyfile> is the path to your public/private key pair and public IP for your machine> is taken from the instance description, available on the EC2 console.

  • Installing ZMQ, on an EC2 instance running Amazon linux:

    • sudo yum group-install "Development Tools"
    • curl -O http://download.zeromq.org/zeromq-4.0.3.tar.gz
    • tar -xvf zeromq-4.0.3.tar.gz
    • cd zeromq-4.0.3
    • ./configure
    • sudo make install
    • sudo make check Succeeds but all tests will fail if no sudo
    • sudo ldonfig /usr/local/lib
    • System can now compile and run basic C calls to 0mq but sudo easy_install pyzmq still fails
    • PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
    • export PKG_CONFIG_PATH
    • Now python setup.py install finds zmq but still fails to compile timer_create or init_threads. Perhaps because Amazon comes with Python 2.6 and it's probably not the full development version?

  • Installing Python distribution with all necessary libraries and packages:

    • Download Anaconda 1.8.0 curl -O http://09c8d0b2229f813c1b93-c95ac804525aac4b6dba79b00b39d1d3.r79.cf1.rackcdn.com/Anaconda-1.8.0-Linux-x86_64.sh
    • Check MD5: md5sum Anaconda[TAB]
    • Install Anaconda: bash Anaconda[TAB]
    • Result includes boto, zmq, redis, ipython. Runs Python 2.7, with option to insall 3.3 using conda package manager.

  • ssh sessions into EC2 instances will simply drop with broken pipe at times. To fix, set ServerAliveInterval 60 in /etc/ssh_config or /etc/ssh/ssh_config. Might also set ClientAliveInterval 60 in /etc/ssh/sshd_config on EC2 instance.
