Thanks
Hi, I've just installed webwork on Fedora 9, and almost everything is fine, but when I try to create my first course following the instructions, this message appears twice:
Thanks
Thanks
Make sure that the webserver has permission to write in the directory
/opt/webwork/courses/admin/logs
(You created the admin course from the command line and probably did it while logged in as yourself or as root. The webserver didn't have write permission on the directory logs and couldn't create the log file login.log)
You could change ownership of the entire admin course so that it is owned by the webserver (the same ownership as the other courses).

Hi thanks for your reply, I've checked the permissions on that directories, but now I get this warning:
The problem is similar to te other one, but I've folowed again the installing intructions and I have the same problem.

An error occured while creating the course MyTest:
Can't create the course 'MyTest' becasue the root directory '/opt/webwork/courses/MyTest' could not be created: Permission denied. at /opt/webwork/webwork2/lib/WeBWorK/ContentGenerator/CourseAdmin.pm line 724The problem is similar to te other one, but I've folowed again the installing intructions and I have the same problem.

Again the webserver needs write permission on the directory
/opt/webwork/courses
so it can create the new directory /opt/webwork/courses/MyTest
take a look at
to review the permissions needed on each directory.

this is my /opt/webwork/courses directory
In the directory
/opt/webwork
type
ls -ld courses
to show the permissions for the courses directory.
I suspect that you'll find that the /opt/webwork/courses directory
doesn't have write permission for the group wwdata.
chmod 775 courses
should fix the permissions so that the webserver can create subdirectories
in /opt/webwork/courses
Hope this helps.

This is strange.
I get these messages only after upgrading to apache2 from apache1.
I did reset and checked the permissions several times:

Hi Andras,
I have only done a new install of apache2, not an upgrade from apache1. Is it possible that with an upgrade, apache2 is running as a user other than apache?
Run the command "ps -aux" and see what user the /usr/sbin/httpd processes are running under.

Arnie,
Is SELinux is enabled for you?
My problem was with SELinux.
Maybe it is not a problem anymore in fc9, but I am still running fc6.
On Fedora 6 with SELinux enabled the following security context modification
makes the problem go away (files get write permission through httpd)
sudo chcon -R -t httpd_sys_script_rw_t /opt/webwork/webwork2/logs
and from the /opt/webwork/courses directory
sudo chcon -R -t httpd_sys_script_rw_t */logs
sudo chcon -R -t httpd_sys_script_rw_t */scoring
I wonder if upgrading to fc9 will help.

After several more "chcon -R -t httpd_sys_script_rw_t" did not fix all the warnings I just discovered in the webwork-fedora installation manual:
>> Under
SELinux select Disabled, click Forward and then click Yes to confirm I did not read this part before since it was not a fresh installation.
Andras
Michael, Andras thankyou soooo much!!! the problem was solved after viewing the last reply, where Andras mentioned Selinux, then I verified and solve my problem; sorry, surely I missed this step while I was configurating my webwork that now is working.
Thanks Thanks
Thanks Thanks
