This is a Sage computation web service.
Make sure you have git; if you're on Ubuntu, you’ll also need the UUID dev package for ØMQ (uuid-dev on Ubuntu, libuuid-devel on Redhat).
Compile Sage 5.10.rc1 (download it from http://www.sagemath.org/download-latest.html).
Delete the IPython installation in Sage: go to SAGE_ROOT/local/lib/python/site-packages/ and delete the IPython directory and the ipython egg.
Install ipython past commit ipython/ipython@0d4706f74b5b454c0a54026547a286caa786e6a4. For example, you can do this:
sage -sh -c "easy_install https://github.com/ipython/ipython/archive/0d4706f.zip"
UPDATE: the current codebase now requires IPython with this pull request applied: https://github.com/ipython/ipython/pull/4195
Install the latest sagecell spkg at http://sage.math.washington.edu/home/jason/sagecell-spkg/ (replace <filename> below with the name of the current spkg):
sage -i http://sage.math.washington.edu/home/jason/sagecell-spkg/<filename>.spkg
To start up, go into the $SAGE_ROOT/devel/sagecell directory and do:
- Copy the config_default.py file to config.py and edit the sage variable and username/host variables. In particular, the host and username variables should point to an SSH account that you can log into without typing in a password. For example, by default, it assumes you can do ssh localhost without typing in a password. You’ll want to change this to a more restrictive account; otherwise anyone will be able to execute any code under your username. You can set up a passwordless account using SSH: type “ssh passwordless login” into Google to find lots of guides for doing this, like http://www.debian-administration.org/articles/152.
- ../../sage -sh -c "make -B" (We run it inside of sage -sh so that make can find the root Sage directory for various IPython files it needs. If Sage is in your $PATH, you can run it normally.)
- ../../sage web_server.py
The biggest potential troublesome spot in the installation is that the spkg has to apply two patches to Sage. If you have uncommitted changes, or if you have conflicts, the installation will stop.
The default configuration is not secure, so you'll need to do more work to harden the system to open it up to outside users. But at least that should get you up and running for a personal/development server.
See the :doc:`Advanced Installation <advanced_installation>` guide for more details about configuring and running a server.
