Question

我需要诊断为什么ldconfig似乎找不到我为其提供路径的.so文件的帮助。

我正在设置将以mod_wsgi / httpd开头的Python flask应用程序。我正在将Anaconda用于我的Python环境控制，并已通过mod_wsgi将pip安装到Anaconda环境中。我通过httpd.conf为mod_wsgi-express module-config文件生成了配置行，如以下问题Anaconda + Apache + mod_wsgi + Ubuntu所述。尝试启动httpd时，出现此错误

httpd: 
Syntax error on line 353 of /etc/httpd/conf/httpd.conf: 
Syntax error on line 4 of /etc/httpd/conf.d/myserver.httpd.conf: 
Cannot load /conda/envs/my_env/lib/python3.5/site-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so into server: 
/conda/envs/my_env/lib/python3.5/site-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so: 
cannot open shared object file: 
Permission denied

看着这个错误，我发现了这个问题：Can't load mod_wsgi compiled for Python 3，并尝试了其中所述的选项：Or add the directory /opt/anaconda/anaconda3/lib to the library search path using a conf file in /etc/ld.so.conf.d/, that would be a global setting tough.

我用以下行创建了mod_wsgi.conf

/conda/envs/my_env/lib

在目录/etc/ld.so.conf.d内并运行ldconfig以刷新ld.so.cache。使用-v运行时，我可以看到/lib内部的.so已成功链接。重新启动httpd会产生相同的结果，并且我注意到mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so未包含在详细列表中。然后，我将以下行添加到mod_wsgi.conf

/conda/envs/my_env/lib/python3.5/site-packages/mod_wsgi/server

并重新运行ldconfig，但是mod_wsi*.so并未出现在详细列表中。

包括以下文件：

myserver.httpd.conf

ServerName myserver.example.com

LoadModule wsgi_module "/conda/envs/my_env/lib/python3.5/site-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so
WSGIPythonHome "/conda/envs/myenv"

Listen 8008

<VirtualHost *:8008>
    ServerName myserver.example.com
    ServerAlias myserver.example.com
    ServerAdmin webmaster@example.com

    WSGIDaemonProcess myapp
    WSGIScriptAlias /myapp /usr/local/src/myapp.wsgi

    <Directory /usr/local/src>
        WSGIProcessGroup myapp
        WSGIApplicationGroup %{GLOBAL}
        Require all granted
    </Directory>
</VirtualHost>

mod_wsgi.conf

/conda/envs/my_env/lib
/conda/envs/my_env/lib/python3.5/site-packages/mod_wsgi/server

这就是我从ldconfig -v得到的：

在此先感谢您的帮助！

即使在.conf文件中指定了.so的目录路径，{ld44}也找不到.so
