Objet : [PROVENANCE INTERNET] perfsonar on CentOS 7

 

Hi Guys,

 

I just tested a perfSONAR install on an Centos7 VM…

I found 2 issues for now :

 

-          The repos are mixing RPMs with the testing key and the internet2 key

 

#internet2 key

[root@dev7252 ~]# rpm -qivp http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/bwctl-client-1.6.2-1.el7.centos.x86_64.rpm|grep Sig

#testing key

[root@dev7252 ~]# rpm -qivp http://software.internet2.edu/rpms/el7/x86_64/main/RPMS/esmond-2.1.2.2-1.el7.centos.x86_64.rpm|grep Sig

I don’t think using “testing” rpms in non testing repos is a good practice, even if the install instructions on the website would not trigger this error as the perfSONAR repos RPM contains both keys. After installing the testing key, the (rpm) install  went ok.

 

-          Second issue, and that one is a bug : “yum install perfonsar-toolkit” will not install a working toolkit. there’s now a (new?) missing dependency on “perl-Sys-Statistics-Linux”

 

The error I found in httpd/registration daemon and meshconfig agent if I remember correctly were like this :

 

-- Unit perfsonar-lsregistrationdaemon.service has begun starting up.

Dec 18 16:02:30 dev7252._my domain_ lsregistrationdaemon.pl[19945]: Can't locate Sys/Statistics/Linux.pm in @INC (@INC contains: /usr/lib/perfsonar/bin/../lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/li

A yum install and systemctl restart later, things started ok.

This is now my list of (previously) unspecified deps :

 

'libgomp','php','php-gd','php-xml','php-snmp','mysql','mysql-devel','perl-DBI','perl-DBD-MySQL', 'perl-Sys-Statistics-Linux'

 

I think I can get rid of mysql and perl-dbd-mysql, but I’m not sure about the other php-* : I tried a yum remove on php-{gd,xml,snmp} and this did not trigger any other package removal which I find dubious…

Libgcomp is now a gcc dep, so I can safely remove it from  my  list.

 

Regards

Frederic
