Apache如何使用Python / 2.x中的Python / 3.x？
我现在正在尝试使用Py3在服务器上设置Django应用程序。
命令python manage.py runserver成功。
然后我尝试使用Apache和mod_wsgi，但我得到Internal Server Error。
错误日志说
[mpm_prefork:notice] [pid 30732] AH00163: Apache/2.4.6 (CentOS) mod_wsgi/3.4 Python/2.7.5 configured -- resuming normal operations
但是默认的python是Py3。
# python -V
Python 3.5.1
我想知道当apache使用Py3时错误将被修复。你呢？ 如何指定Py3？
# /etc/init.d/httpd restart
$ tailf /etc/httpd/logs/error_log

如果您正在使用已编译的 mod_wsgi ，则需要针对您要使用的版本针对相应的Python二进制文件对其进行编译，或者它默认为系统Python版本（不幸的是仍然是2.x）。例如：
wget -q "https://github.com/GrahamDumpleton/mod_wsgi/archive/4.4.21.tar.gz"
tar -xzf '4.4.21.tar.gz'
cd ./mod_wsgi-4.4.21
./configure --with-python=/usr/local/bin/python3.5
make
make install
