I am after the settings at the head of:
/tmp/mod_wsgi-localhost:8000:1000/apachectl
Specifically, what is HTTPD in that file set to.
I suspect the problem is the code:
def _mpm_module_defines(modules_directory):
result = []
workers = ['event', 'worker', 'prefork']
for name in workers:
if os.path.exists(os.path.join(modules_directory,
'mod_mpm_%s.so' % name)):
result.append('-DWSGI_MPM_%s_MODULE' % name.upper())
return result
It should be breaking out of the loop after result.append().
It is likely adding more than one of:
WSGI_MPM_EVENT_MODULE
WSGI_MPM_WORKER_MODULE
WSGI_MPM_PREFORK_MODULE
and so trying to load more than one.
The solution you can like use for now is to create/edit the file:
/tmp/mod_wsgi-localhost:8000:1000/envvars
Take from /tmp/mod_wsgi-localhost:8000:1000/apachectl the HTTPD variable line
and copy it into the envvars file.
Edit the HTTPD setting in envvars to drop out all but one of the MPM -D
options. Give preference to event or worker MPM over prefork.
