Name : python27-mod_wsgi

Version : 3.4

Release : 12.sc1.el6

Repo : installed

From repo : centos-sclo-rh

Summary : A WSGI interface for Python web applications in Apache

URL : http://modwsgi.org

License : ASL 2.0

Description : The mod_wsgi adapter is an Apache module that provides a WSGI compliant

: interface for hosting Python based web applications within Apache. The

: adapter is written completely in C code against the Apache C runtime and

: for hosting WSGI applications within Apache has a lower overhead than using

: existing WSGI adapters for mod_python or CGI.

I did add the internet-2 repo rpm following CentOS bundle installation. Is the above info implies the wrong version of python27-mod_wsgi?

Thanks.

Hi,

What’s “yum info python27-mod_wsgi” show?

My guess would be that you have the wrong version of the above package. You need the version from the Internet2 repo. If you are also pointing at the SCL repos you may have gotten the version they provide. If that’s the case, you should disable the SCL repos (yum remove centos-release-scl) and try a “yum downgrade python27-mod_wsgi” or you may need to reinstall python27-mod_wsgi.

Thanks,
Andy

Hello Antoine:

Thank you for your reply.

The log messages in the original email is the last updated log file. Both access_log and error_log was last updated June 22nd.

I found out the toolkit is down on June 21st. The error message in my browser is

"206.196.179.148 refused to connect. Try: Reloading the page; Checking the connection; Checking the proxy and firewall"

I just checked the access_log. The last updated entries is:

I checked the apache status, it shows not running (/etc/init.d/httpd status). I tried to restart it, it shows:

The /etc/httpd/conf.d/apache-esmond.conf file is like this:

Hi Hao,

The log messages you’re sending us is old, probably older then your web interface issue. Do you see anything else? Is there any recent entries in /var/log/httpd/access-log ?

Can you see the apache processes running?

When you say the the web interface cannot be opened, what is the error message you get in your browser?

Thanks,
