Hi, I get an internal (500) server error when trying to run the TWiki configure script: Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log. Apache/2.2.17 (Fedora) Server at mikes-fedora Port 80 --

The httpd error log shows: [Wed Mar 09 10:21:17 2011] [error] [client 192.168.1.100] (13)Permission denied: exec of '/var/www/twiki/bin/configure' failed, referer: http://mikes-fedora/twiki/ [Wed Mar 09 10:21:17 2011] [error] [client 192.168.1.100] Premature end of script headers: configure, referer: http://mikes-fedora/twiki/

I am running Fedora 2.6.35.11 PHP 5.3.5 Perl 5.12.3 TWiki 5.0.1 with a pretty much default installation configuration for both Fedora and TWiki. The TWiki root path is /var/www/twiki. Permissions in twiki path are set to defaults (as unpacked) but owner:group is apache:apache.

The config file /etc/httpd/conf.d/twiki.conf was generated from the online TWiki tool (http://twiki.org/cgi-bin/view/TWiki.ApacheConfigGenerator, see below).

I tried changing ownership, permissions of ~twiki/bin/configure to root - no difference. I also tried solutions to similar problems on this web site but none affected this problem.

I'm pretty sure the problem lies in the httpd configuration but am not experienced enough in Apache to fully comprehend it. Thoughts, ideas, comments? Thanks.

# We set an environment variable called blockAccess. # # Setting a BrowserMatchNoCase to ^$ is important.

Discussion and Answer

Same Problem here.

Have you fixed it yet?

I can run the configure script once, but on the last stage where I can click "save" i got a 500 internal server error. From this point I cant run the script again. First I have to restart my apache.

-- RolandWurzer - 2011-03-15

Mike: Permission denied, exec of '/var/www/twiki/bin/configure' failed is an indication that the script cannot be executed due to permission issues. Check the file ownership and permission of the configure script and of the twiki/bin directory. In case you run under Selinux, turn it off to check if this is the issue.

Roland: If you get a 500 internal server error, check the apache error_log, it tells more details.

I disabled selinux and rebooted the server. Works ok now. Thanks!

-- MikePitcher - 2011-03-17

Consider re-enable selinux and configure it to allow the twiki scripts.

Hi,

When I try http://<myip>:8769/bin/configure in my browser after all setup, I get error 500. When I see apache error logs it says

[Fri Sep 23 15:04:57 2011] [error] [client myip] Can't locate strict.pm in @INC (@INC contains: /tmp/perl---------------------------------------------please-run-the-install-script---------------------------------------------/site/lib /tmp/perl---------------------------------------------please-run-the-install-script---------------------------------------------/lib .) at <myhome>/bin/configure line 71. [Fri Sep 23 15:04:57 2011] [error] [client myip] BEGIN failed--compilation aborted at <myhome>/bin/configure line 71. [Fri Sep 23 15:04:57 2011] [error] [client myip] Premature end of script headers: configure

Please help

Thanks, Sunil

It is best to open a new support question with detail of environment. It is hard to help without enough info, such as OS. If Oracle Linux see http://oracleappstechnology.blogspot.com/2011/05/cant-locate-strictpm-in-inc.html
