#summary basic installation description, cheat sheet for developers

Installation

• Clone the repository: hg clone http://lmfdb.googlecode.com/hg/ lmfdb

• Install dependencies, i.e. you need Sage. Inside the Sage environment sage -sh: easy_install -U flask easy_install -U flask-login easy_install -U pymongo easy_install -U flask-markdown easy_install -U flask-cache

• From the command-line: sage -i gap_packages (should check if we really need gap_packages.) sage -i database_gap

• Regarding !MathJax: No longer necessary to install !MathJax, because it is downloaded from their CDN directly!

  • old and obsolete info: get [http://www.mathjax.org/download/ the latest release or beta, i.e. v1.1+], extract, and put the resulting !MathJax directory as lmfdb/static/MathJax in your lmfdb repo.)

• MongoDB: port forward boxen to get full database: ssh -C -N -L 37010:localhost:37010 [username@]boxen.math.washington.edu (if "boxen" doesn't work, try "mod")

  • -C for compression of communication
  • -N to not open a remote shell, just a blocking command in the shell (end connection with Ctrl-C) If you don't have access to this server, you can temporarily start your own mongodb server and use it locally. There is no data (obviously) but it will work.
  • Mongo locally: mongod --port 40000 --dbpath [db_directory] --smallfiles

Note: Inside Sage, you might have to update the setuptools first, i.e. easy_install -U setuptools

Optional Parts

• dirichlet_conrey.pyx:

goto [https://github.com/jwbober/conrey-dirichlet-characters its github page]
download dirichlet_conrey.pyx and setup.py
run: `sage setup.py install`
if it doesn't compile, update sage's cython and then try again:
    `sage -sh`
    `easy_install -U cython`
    `exit`

• Memcache:

   ` easy_install -U python-memcached` or even better and only possible if you have the dev headers: ` easy_install -U pylibmc `
   install *memcached* (e.g. ` apt-get install memcached `)
   run the service at 127.0.0.1:11211

Running

Once everything is setup, sage -python website.py --debug should do the trick, but there can be some problems running in debug mode, so you might have omit the --debug. Once the server is running, visit http://localhost:37777/

Maybe, you have to suppress loading of your local python libraries: sage -python -s website.py

If you use a local MongoDB instance, specify its port: sage -python website.py --debug --dbport 40000

Sharing Your Work

• Create a clone webpage by clicking on the Create a Clone button here.
• Push your code to the clone. (WARNING: This requires that the _ssl module built correctly into Sage if you use Sage's hg.)
• Tell the lmdb mailing list that you have some new code!
