perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Prior to RC3 (and again when we released RC3) we provided some special upgrade instructions for RC2 users to prevent this. RC2 points at the CentOS SCL repo, which decided to add their own version of python27-mod_wsgi which does not work with the standard apache and overwrites the version we provided.

No worries though, you should be able to get your host back to normal. Run the following:

yum remove centos-release-SCL python27-mod_wsgi python27 python27-python httpd24-httpd httpd24-apr httpd24-apr-util httpd24-httpd-tools httpd24-runtime scl-utils

yum clean all

rm -rf /var/lib/pgsql/data/*

yum install perl-perfSONAR_PS-Toolkit perl-perfSONAR_PS-Toolkit-SystemEnvironment

reboot

Thanks,

Andy

Hi all,

 

We have a perfSonar 3.4rc2 test box running. We have recently updated the system and it has those perfSONAR packages:

 

perl-perfSONAR-OPPD-MP-Shared-3.4-2.pSPS.noarch

perl-perfSONAR_PS-Toolkit-3.4-25.pSPS.noarch

perl-perfSONAR_PS-LSCacheDaemon-3.4-1.pSPS.noarch

perl-perfSONAR_PS-MeshConfig-Shared-3.4-12.pSPS.noarch

perl-perfSONAR-OPPD-MP-BWCTL-3.4-2.pSPS.noarch

perl-perfSONAR_PS-RegularTesting-3.4-15.pSPS.noarch

perl-perfSONAR_PS-Toolkit-SystemEnvironment-3.4-25.pSPS.noarch

perl-perfSONAR_PS-SimpleLS-BootStrap-client-3.4-3.pSPS.noarch

perl-perfSONAR-OPPD-MP-OWAMP-3.4-2.pSPS.noarch

perl-perfSONAR_PS-serviceTest-3.4-13.pSPS.noarch

perl-perfSONAR-OPPD-MP-server-3.4-1.pSPS.noarch

perl-perfSONAR_PS-LSRegistrationDaemon-3.4-2.pSPS.noarch

perl-perfSONAR_PS-MeshConfig-JSONBuilder-3.4-12.pSPS.noarch

perl-perfSONAR-OPPD-MP-server-3.4-2.pSPS.noarch

perl-perfSONAR_PS-MeshConfig-Agent-3.4-12.pSPS.noarch

 

The perfsonar daemon appears to be running on the system, but the web GUIS is not

 

/etc/init.d/httpd status

httpd is stopped

 

/etc/init.d/httpd start

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

                                                           [FAILED]

 

The wsgi modules for the (system) httpd is not installed.  However, I noticed that there is a new package httpd24 along with its own wsgi module, I am able to start the httpd24-httpd daemon, but the familiar toolkit is nowhere to be seen on the web GUI.

 

Could someone shed some light on how I suppose get the new perfSONAR going?

 

Thank you very much for your help.
