perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

If you run "yum repolist” do you have the SCL repo installed (will probably be named something like centos-sclo)? You may have grabbed a version of python27-mod_wsgi that causes some problems for perfSONAR. You can also check with “yum info python27-mod_wsgi”. If the repo is Internet2 you are in good shape, otherwise you may have a bad version. I’d imagine the problem would appear sooner, though maybe apache hasn’t been restarted in awhile so it just rearing its head now. If it is indeed because it grabbed the SCL version I can help you get it back on the right one.

Thanks,

Andy

We are running three 3.5.1 servers that were originally installed from a CentOS 6 ISO.  These servers auto-update and I don’t need to touch them except to reboot when  a new kernel comes out, which I did prior to Christmas.

Today, before editing the HTTPD config to implement stricter SSL ciphers I ran “httpd –t” and got this:

httpd: Syntax error on line 239 of /etc/httpd/conf/httpd.conf: Syntax error on line 1 of /etc/httpd/conf.d/wsgi.conf: Cannot load /etc/httpd/modules/mod_wsgi.so into server: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

I checked my other two servers and got the same thing.  I checked the YUM history and I see it picked up a couple of updates after my reboot:

ID     | Login user               | Date and time    | Action(s)      | Altered

   129 | root <root>              | 2017-01-04 04:16 | Update         |   50   

   128 | root <root>              | 2016-12-22 03:54 | Update         |    4   

Is it possible that something got corrupted in one of these recent updates?
