I've lost count of the amount of times I've had to research this on a fresh install or different machine. Since python is not a language I use day to day, I constantly forget the environment configuration so I'm putting it here for quick reference when I will inevitably need it in a month or two.
I've lost count of the amount of times I've forgotten the syntax for creating users, databases and permissions within postgresql. After spending so many years working with MySQL it became muscle memory and for some reason I can't shake those commands. Unlike MySQL, which I used to host myself and understand the internals of security/performance, I've only ever used hosted versions of PostgreSQL where all of this is taken care of.
Here is a small script I whipped up while I was bored in the Travelodge waiting for #MongoDBUK. It's basically a drop in script to make sure MongoDB is installed with the default settings, and up to date. Very simple, but it saves running the commands manually each time. I may update this in the future when I find a better way to check if a key is already added before always inserting it #!/usr/bin/env sh # Sudo is required to install everything properly if [ "$(whoami)" != "root" ]; then echo "You need to use sudo to run this command" exit 0; fi echo "Installing MongoDB, please be patient, this could take a few minutes.." REPOSOURCE="deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen" REPOFILE=/etc/apt/sources.list # Make sure packages are up to date and key exists apt-get update -qq && sudo apt-get upgrade -qq -y apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10 # Append to repo if ! grep -Fxq "$REPOSOURCE" $REPOFILE then echo ": Adding $REPOSOURCE to $REPOFILE" echo "$REPOSOURCE" >> $REPOFILE apt-get update -qq fi # Run install apt-get install -y mongodb-10gen I normally put this in my home folder at ~/install-mongodb then run it using sudo ./install-mongodb. Note that sudo is actually a requirement, and the script will warn you if it you don't have root permissions. I will add more scripts in the next few hours as I go through the MongoDB UK workshops to have simple ways of switching configs for different scenarios and replacing the defaults to enable auth, for example. If you have any cool things you'd like me to write about regarding MongoDB please feel free to ask in the comments.
