Question

我使用：

重新编译了python2.7.11

./configure
make
make altinstall
sudo ln -s /usr/local/bin/python2.7 /usr/local/bin/python
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo /usr/local/bin/python
sudo /usr/local/bin/easy_install pip
sudo pip install virtualenv
sudo pip install virtualenvwrapper
source /usr/local/bin/virtualenvwrapper.sh

我已经安装了django和所有依赖项，检查pip位于我的新python版本中

我卸载了mod_wsgi和的打包版本我已经通过以下方式将mod_wsgi链接到新版本的python：

./configure --with-python=/usr/local/bin/python
make install

当我重新启动apache时，似乎启动了2.7.6和2.7.11：

[Wed Apr 27 01:46:21.085703 2016] [wsgi:warn] [pid 18410:tid 140116611360640] mod_wsgi: Compiled for Python/2.7.11.

我的httpd.conf看起来像：

WSGIPythonHome /home/vagrant/.virtualenvs/django_2.7.11_env
<VirtualHost *:80>
  ServerName server.dev
  ServerAlias www.server.dev

  WSGIDaemonProcess server.dev python-path=/var/www/app:/home/vagrant/.virtualenvs/django_2.7.11_env/lib/python2.7/site-packages
  WSGIProcessGroup server.dev

  ## Vhost docroot
  DocumentRoot "/var/www/app"
  Alias "/sitemap.xml" "/var/www/app/static/sitemap.xml"
  <Directory /var/www/app/static>
      Require all granted
  </Directory>


    <Directory /var/www/wsgi-scripts>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

  ## Logging
  ErrorLog "/var/log/apache2/av_app_nma_api_error.log"
  ServerSignature Off
  CustomLog "/var/log/apache2/av_app_nma_api_access.log" combined

  WSGIScriptAlias / /var/www/wsgi-scripts/wsgi.py
</VirtualHost>

我能够运行“hello world”wsgi应用程序，即使似乎使用了两个版本的python。但是，当我使用django应用程序时，我最终得到的ImportError似乎与多个版本有关。

回复@Graham：make命令失败，如下：

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32S against `_Py_NotImplementedStruct' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libpython2.7.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
apxs:Error: Command failed with rc=65536
.
make: *** [src/server/mod_wsgi.la] Error 1

Answer 1

尝试：

make distclean
./configure --with-python=/usr/local/bin/python
LD_RUN_PATH=/usr/local/lib make
sudo make install

构建时LD_RUN_PATH环境变量将包含正确库的目录路径嵌入到mod_wsgi.so文件的查找路径中。

无法使用系统版本的python 2.7.6而不是virtualenv版本停止apache
