linux - 无法使用 python 2.7.6 的系统版本而不是 virtualenv 版本停止 apache

Question

我已经使用以下方法重新编译了 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 是否位于我的新 python 版本中

我卸载了 mod_wsgi 的打包版本并且我通过以下方式将 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，2.7.6 和 2.7.11 似乎都已启动:

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>


    <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，我最终遇到了一个似乎与多个版本相关的 ImportError。

Answer 1

尝试:

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

构建时的 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。
