Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled.  See sysctl(8) and
# sysctl.conf(5) for more details.

# Turn on execshield
# 0 completely disables ExecShield and Address Space Layout Randomization
# 1 enables them ONLY if the application bits for these protections are set to “enable”
# 2 enables them by default, except if the application bits are set to “disable”
# 3 enables them always, whatever the application bits

Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

Solution

betrcode

Using Python to check if remote port is open and accessible.

Taken from http://snipplr.com/view/19639/test-if-an-ipport-is-open/

Usage:

• Open a Python prompt
• Run the script in is_port_open.py
• Call isOpen with a host and a port parameter. Example: isOpen("www.google.com", 80)
