MongoDB 3.2.x Replica Sets on AWS EC2

#MongoDB 3.2.x Replica Sets on AWS EC2 A MongoDB replica set provides a mechanism to allow for a reliable database services. The basic replica set consists of three servers, a primary, a secondary and an arbitrator. The primary and secondary both hold a copy of the data. The arbitrator is normally a low spec server which just monitors the other servers and help with the failover process. In production, there can be more than three servers.

To setup mongo as a replica set on Amazon Web Services EC2 you need to first setup a security group with ssh on port 22 and mongodb on port 27017. You then need to create three servers. Select Ubuntu 14.04 LTS x64 and a micro (or bigger depending on your database size, ideally you should have enough memory to match your database size) instance for the primary and secondary and a nano instance for the arbitrator.

##Adjust the File System on each Server The operating system by default will update the last access time on a file. In a high data throughput database application

Do you own a DSLR? If so, do you transfer your images to your computer, then look at the JPEGs and delete the crappy ones? If you do, your RAW images may be leftover. This Python script helps you cleaning up your image folders after deleting unwanted JPEGs. See http://blog.philippklaus.de/2012/12/cleaning-leftover-raw-images-after-selecting-imag…
