在Linux上使用mod_wsgi时为什么发生错误？

Question

我遵循django教程和mod_wsgi安装指南在LinuxMint18.1上使用Apache和mod_wsg，但是当我运行apache2ctl start时出现错误。

Current thread 0x00007f88c10c7780 (most recent call first): 
[Mon Mar 20 21:23:28.781270 2017] [core:notice] [pid 32458:tid 140225331099520] AH00052: child pid 7962 exit signal Aborted (6) 
Fatal Python error: Py_Initialize: can't initialize sys 

我怎么了？

我按照下面的步骤来安装Apache和mod_wsgi的：

1. 易于得到安装的Apache2
2. 的apt-get安装的apache2-dev的
3. 的apt-get安装python3.5-dev的
4. wget的https://github.com/GrahamDumpleton/mod_wsgi/archive/4.5.15.tar.gz
5. 焦油-zxvf mod_wsgi的-4.5.15.tar.gz
6. CD mod_wsgi的-4.5.15
7. 的./configure --with-蟒=的/ usr /斌/ python3.5
8. 使
9. 使安装

的ls /usr/bin/ -aoh |grep python输出是：

我遇到了一堆类似的问题，花了相当多的时间解决它们。最后，我写了下面的说明来使用RHEL7。您可能正在使用Ubuntu，因此请阅读下面的配方并相应地进行更改。它可能有帮助。

Setup: RHEL 7, Apache 2.4, Python3.5 
------------------------------------------------------------------------- 
1. mod_wsgi-------------------------------------------------------------- 
------------------------------------------------------------------------- 
See how I used my python3.5 interpreter to install mod_wsgi. 
wget https://github.com/GrahamDumpleton/mod_wsgi/archive/4.5.14.tar.gz 
tar -zxvf 4.5.14.tar.gz 
cd mod_wsgi-4.5.14 
./configure --with-python=/usr/bin/python3.5 
make 
make install 
chmod 755 /usr/lib64/httpd/modules/mod_wsgi.so
