Starting uWSGI - galaxy-dev

17 Feb 2015


      Hi Nate,
So I went ahead and set `static_enabled = False` in universe_wsgi.ini,
restarted uWSGI, and browsed to localhost. I'm including the results
of each step below:
After restarting uWSGI, the last few lines of uwsgi.log looked like this:
WSGI app 0 (mountpoint='') ready in 11 seconds on interpreter
0xa934c0 pid: 3561 (default app)
    *** uWSGI is running in multiple interpreter mode ***
    spawned uWSGI master process (pid: 3561)
    spawned uWSGI worker 1 (pid: 3575, cores: 4)
    spawned uWSGI worker 2 (pid: 3576, cores: 4)
    spawned uWSGI worker 3 (pid: 3583, cores: 4)
    spawned uWSGI worker 4 (pid: 3587, cores: 4)
    spawned uWSGI worker 5 (pid: 3591, cores: 4)
    spawned uWSGI worker 6 (pid: 3595, cores: 4)
    spawned uWSGI worker 7 (pid: 3599, cores: 4)
    spawned uWSGI worker 8 (pid: 3603, cores: 4)
    spawned uWSGI worker 9 (pid: 3607, cores: 4)
    spawned uWSGI worker 10 (pid: 3611, cores: 4)
    *** Stats server enabled on 127.0.0.1:9191 fd: 30 ***
...so no traceback this time!
Then, browsing to localhost redirects to https://localhost and finally returns:
"Internal Server Error Galaxy was unable to successfully complete
your request An error occurred. This may be an intermittent problem
due to load or other
unpredictable factors, reloading the page may address the problem. The
error has been logged to our team."
That request was logged to uwsgi.log:

I thought I would include some pieces of universe_wsgi.ini to help
with troubleshooting:
# ---- HTTP Server

# Configuration of the internal HTTP server.
[server:main]
# The internal HTTP server to use.  Currently only Paste is provided.  This
    # option is required.

    #port = 8080
# The address on which to listen.  By default, only listen to

    # will not be accessible over the network).  Use '0.0.0.0' to listen on all

    host = 0.0.0.0
# Use a threadpool for the web server instead of creating a thread for each

    use_threadpool = True
# Number of threads in the web server thread pool.
    threadpool_workers = 10
# Set the number of seconds a thread can work before you should

    processes = 10
    stats = 127.0.0.1:9191
    socket = 127.0.0.1:4001
    pythonpath = lib
    threads = 4
    logto = /home/galaxy/galaxy-dist/uwsgi.log
    master = True
Also, we are using a self-signed certificate as a temporary solution,
so not sure if that matters.
Thanks!
