Just to answer myself... Those 2 location blocks should be in the same server block! Hope this could help someone else... :) Rui On Sat, May 17, 2014 at 8:54 PM, ruiwang.sz <ruiwang.sz@gmail.com> wrote:

Hi Guys,

I just switch to 1.6.0 of nginx, but the behavior is the same. I also tried the apache proxy instructions, but rewrite just didn't work. I searched around, did what I could, verified that I did have the required module, etc, but still didn't work -- it is so frustrating.

For nginx, at least redirect works, but I don't know why there is only one server block in use at a time. How do I solve this? Any help would be greatly appreciated.

Thanks, Rui

Hi Guys,

I did a little further investigation. I found that the order of 2 server blocks matter in my case.

If I put the /_x_accel_redirect/ block first, then the 2nd proxy server block is not effective. If in the order I pasted in the previous message, then the _x_accel_redirect block is not effective.

But why is this? btw I'm using the 1.1.19 version of nginx that comes with ubuntu.

Could anyone give me a hint? I'll be really grateful.

Thanks, Rui

Hi All,

I have been trying to get the visualization through ucsc main working, thus I installed the nginx on our ubuntu(the one comes with update), then I configured it according to the wiki

https://wiki.galaxyproject.org/Admin/Config/nginxProxy

Here is the section in my nginx.conf

include /etc/nginx/conf.d/*.conf; #include /etc/nginx/sites-enabled/*;

upstream galaxy_app { server localhost:20020; } server { client_max_body_size 10G; # ... other server stuff ... location / { proxy_pass http://galaxy_app; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } server { location /_x_accel_redirect/ { internal; alias /; } }

A couple notes:

1. I commented out

#include /etc/nginx/sites-enabled/*;

should I?

2. I have two sections of 'server', I am not sure if this is correct, but the wiki does not talk about it.

I also have the following in universe_wsgi.ini:

nginx_x_accel_redirect_base = /_x_accel_redirect

Now, if I go to http://127.0.0.1, it will redirect to http://127.0.0.1:20020, our galaxy instance, which is right. However, when i choose 'display in UCSC main' on a bigwig file, it failed to show and here is the log:

I don't know how this works -- the dataset I clicked is in fact:

/home/bioinfoadmin/app/galaxy-dist/database/files/003/dataset_3353.dat

and it is on disk. However, it gave 404:

128.114.119.135 - - [16/May/2014:09:18:20 -0700] "HEAD /_x_accel_redirect/home/bioinfoadmin/app/galaxy-dist/database/files/003/dataset_3353.dat HTTP/1.0" 404 - "-" "genome.ucsc.edu/net.c"

seems '_x_accel_redirect' is not substituted by the redirect alias '/'? but why?

I checked the permission and it is 775 for all the dir on path, and 664 for dataset_3353.dat

so www-data user has the read access.

Also, where is this dir and file?

/display_application/360b40e91c77a7e9/ucsc_bigwig/main/6e1547da5bd290c9/data/galaxy_360b40e91c77a7e9.bigwig

I don't see them anywhere on the disk at all!

I'm very confused about this. Could anyone give me a hand? I'll really appreciate!

Thanks, Rui
