mod_wsgi Apache error with django app

2019-08-05 10:01发布

问题:

I have a django (1.7) app that works pretty well on a Centos7 server. Now i moving to production server RHEL 6 and still have some issues.

The problem is the mod_wsgi.

The server config:

  • RHEL6
  • Apache 2.2
  • Django 1.7
  • Python 2.6

the apache error log

I thought that a problem could be that mod_wsgi seems compiled with lib64, so I changed the python path on the flweb.conf to lib64 but it didn't worked

EDIT: I realize the server has python 2.7 in /user/local/lib and that is the python version where django is installed. I changed the path in the conf file, but now I guess I need to rebuild the mod_wsgi

EDIT2: Trying to rebuild mod_wsgi, have this problem

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC

according to https://code.google.com/p/modwsgi/wiki/InstallationIssues is a conflict between python that was compiled to 32 bit and mod_wsgi to 64
