Split monolithic HAProxy configuration
#!/bin/bash
#Requirements: etckeeper, diffcolor
#This script concatenates multiple files of haproxy configuration into
#one file, and than checks if monolithic config contains errors. If everything is
#OK with new config script will write new config to $CURRENTCFG and reload haproxy
#Also, script will commit changes to etckeeper, if you don't use etckeeper you
#should start using it.
#Script assumes following directory structure:
#/etc/haproxy/conf.d/

What to do when promoting a postgresql slave to master

This example is based on having a cascading setup, where you have a single master, a single "primary" slave, and cascading slaves which are being replicated from the primary slave. For an example of this setup, check out http://bartek.im/blog/2012/12/04/postgresql-92-streaming-primer.html

On the existing master, if accessible, stop postgres.

$ sudo service postgresql stop

And better to be safe than sorry. We can't have two masters running. (I only use this in an automated script. If you're doing this manually, you'd know if it was shutoff)

$ kill -9 `sudo cat /var/lib/postgresql/9.2/main/postmaster.pid | head -n 1` &> /dev/null
