Requirements

Here is what you'll want for a development environment. Sure, you can probably get away with less or different, but that's not what we're going to support. The DW code is known to work with the following. But we'd love to hear of your results using something else.

Linux based server

We are presently using Ubuntu. This may stay or become Debian or Centos at some point, that's undecided. But for now, Ubuntu is the supported distro. If you use anything else, you will need to be familiar enough with the differences to work out any different steps on your own. (But we'd love to hear success stories and get documentation for other ones!)

Notes for other OSes:

• Running Dreamwidth on a Mac OS X system

64-bit (x86_64 typically, NOT i686/i386)

This is something you can probably get away without doing, but you'll be unable to test some things and others might be a bit wonky. Notably, you need the 64 bit version of Perl in order for the pack/unpack operations to work for memcache.

But if you absolutely do not have a 64 bit system, then you might still be okay. Don't use memcache and don't try to use more than 30 friend groups and you shouldn't run into any big issues. You will also have to change the pack functions in Entry.pm from using NNNQN to NNNLN to avoid a "Invalid type 'Q' in pack" error when posting to a journal.

If you're not sure whether you have a 64 bit system or not, check out the collection of tips on this page: http://www.stata.com/products/64bit.html

512mb RAM

I have gotten away with less. Depends on how much traffic you expect and what else you are running on the box. Also, if you intend on running TheSchwartz workers or not. If you do not, and you only run the web site code, then it will probably work on 256.

Dedicated!

The LJ/DW code is pretty heavy, and doesn't like other things running. You should expect that if you are not that technical, you will need a fairly blank server to run it on. But if you are technical you can do some pretty convoluted setups... (This one is more of a recommendation and not a hard requirement.)

root

If you do not have root on the box, you are in for a rough road. Sure, the code doesn't need root privileges to run. But there are a lot of libraries that need to be installed on the system. If you are using a shared development environment where the owner has installed the modules for you, then you should be fine, but keep in mind that you will not be able to run the code on the standard HTTP port (80) as a non-root user.

MySQL

You will need a MySQL database. It can be local or remote, it doesn't matter really. As long as you have the ability to create/drop/alter tables in a directory, that's what matters.

Suitable hosting

These hosts are reported to have suitable plans for running Dreamwidth code:

• Linode -- 64-bit available by request, not the default; used by afuna, exor674 and foxfirefey. Instructions for setting up on this host from a pre-built image (from exor674) are on Setting up Dreamwidth on Linode.
• Slicehost -- used by xb95

They are both VPS hosting plans that will give you full root access at a decent price--about $20 a month.
