Enabling / Disabling a service

To toggle a service from starting or stopping permanently you would need to:

echo manual | sudo tee /etc/init/SERVICE.override

where the stanza manual will stop Upstart from automatically loading the service on next boot. Any service with the .override ending will take precedence over the original service file. You will only be able to start the service manually afterwards. If you do not want this then simply delete the .override. For example:

echo manual | sudo tee /etc/init/mysql.override

PostgreSQL Streaming Replication With Docker

The *.txt files here hold user and database parameters. Specifically, replication.txt contains the user/role and password to use for replication. Whereas database.txt contains an initial database, user/role and password to create on the master.

Run the master:

$ fig run -d master

Wait for it to start up completely. Start the slave:

	# Note that target_env.login and target_env.password is global variables

	# Maybe I should add this into Fabric project (http://docs.fabfile.org/en/1.4.2/index.html).
	# This is complicated task for sure but it would be nice if Fabric could use ssh under Linux and PowerShell Remoting under Windows.

	def remote_sh(target_host, command_text, ignore_error=False):
	print('run PowerShell script block at {0}: {1}'.format(target_host, command_text))

	command_text = command_text.replace('"', '\'')

	#!/bin/bash

	usage()
	{
	cat << EOF
	usage: $0 options

	This script set ownership for all table, sequence and views for a given database

	# Windows AMIs don't have WinRM enabled by default -- this script will enable WinRM
	# AND install 7-zip, curl and .NET 4 if its missing.
	# Then use the EC2 tools to create a new AMI from the result, and you have a system
	# that will execute user-data as a PowerShell script after the instance fires up!
	# This has been tested on Windows 2008 SP2 64bits AMIs provided by Amazon
	#
	# Inject this as user-data of a Windows 2008 AMI, like this (edit the adminPassword to your needs):
	#
	# <powershell>
	# Set-ExecutionPolicy Unrestricted
