4.2.2 OMERO.web starts Using FastCGI but URL fails

[bernie]

Looks like I can't upload the file.

Problem solved.

The answer was to be found, of course, in the the list of error messages at the beginning of the thread which ended with:

IOError: [Errno 13] Permission denied: '/home/omero/omero_dist/etc/grid/config.xml'

Gave world readable privileges to:
-rw-rw-r-- 1 omero omero 1172 Jan 27 15:56 config.xml
-rw-rw-r-- 1 omero omero 0 Jan 3 21:02 config.xml.lock
-rw-rw-r-- 1 omero omero 105270 Jan 27 15:55 OMEROweb.log

in turn.

Then concluded that the problem might lie in the fact that apache need to belong to the group omero:

usermod -a -G omero apache

It would seem that this, added apache to the omero group, was all that was needed.

That seems a bit odd based on the fact that the whole point of using FastCGI (particularly when using TCP) is to avoid Apache having to have any access to your OMERO directories.

It would be good to see the Apache configuration files.

Cxallan,

just to confirm, apache was removed from the group omero, the server restarted and the problem returned. apache was added back, the apache server restarted and the problem disappeared.

I've attached the configuration files,

You need to remove all the previous OMERO mod_python configuration from your httpd.conf AND conf.d/python.conf:

Code: Select all

...
<Location "/">
    SetHandler python-program
    PythonHandler django.core.handlers.modpython
    SetEnv DJANGO_SETTINGS_MODULE omeroweb.settings
    PythonDebug On
    PythonPath "['/home/omero/omero_dist/lib/python', '/home/omero/omero_dist/lib/python/omeroweb'] + sys.path"
</location>
...


Then reset the permissions, otherwise Apache is going to be messing around inside your /home/omero directory.

Hi cxallan,

I've done that and restarted the server, in fact rebooted the server because a restart didn't work, but still have the same problem.

Permissions have been reset:

[root@omerodev httpd]# id -nG apache
apache

Using Chrome I can examine elements and get this:

Failed to load resource: the server responded with a status of 404 (Not Found) /appmedia/omeroweb/css/layout-admin.css

Failed to load resource: the server responded with a status of 404 (Not Found)
/appmedia/omeroweb/css/login.css

Failed to load resource: the server responded with a status of 404 (Not Found)
/appmedia/omeroweb/images/logo-admin.png

although these files exist and the Alias paths are defined in httpd.conf

I've re-attached the modified files just in case...

[cxallan]

Your httpd.conf has a spelling mistake:

This line:

Code: Select all

Alias /appmedia /home/omero/OMERO.server-Beta-4.2.2/lib/python/omeroweb/medialias


Should be:

Code: Select all

Alias /appmedia /home/omero/OMERO.server-Beta-4.2.2/lib/python/omeroweb/media

Yep, it works now. Thanks for your patience and help.

No problem. Glad to help.
