perfSONAR User Q&A and Other Discussion

Hi Dan,

You most likely have an incompatible of mod_wsgi installed. This has come up enough to warrant a spot in the FAQ: https://www.perfsonar.net/about/faq/#Q107

Does that resolve your issue?

Hi all,

 

My current perfSONAR setup is an HP server with 8 GB of RAM and an OS of RHEL 6.8. I installed using the CentOS bundle method with perfsonar-toolkit. The web interface was working fine, but after trying to restart httpd to see a certain test result, httpd is no longer able to start, returning the error:

 

Starting httpd: Syntax error on line 1 of /etc/httpd/conf.d/apache-esmond.conf:

Invalid command 'WSGIScriptAlias', perhaps misspelled or defined by a module not included in the server configuration

 

After looking in the regulartesting.log file, I noticed that I was receiving the following errors over and over again:

 

2016/08/31 11:32:11 (10078) ERROR> EsmondBase.pm:53 perfSONAR_PS::RegularTesting::MeasurementArchives::EsmondBase::__ANON__ - Error writing metadata (404) 404 Not Found

I have also tried the steps outlined at http://docs.perfsonar.net/multi_ma_install.html#authenticating-by-username-and-api-key, and changed the API key for user ‘perfsonar’ in regulartesting.conf, but this did not work either. Any and all help is appreciated.

 

Best regards,
