python - Apache 如何使用 Py3 而不是 Py2？

Question

Apache 如何使用 Python/3.x 而不是 Python/2.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 但我遇到了 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

但默认的 python 是 Py3。

# python -V
Python 3.5.1

我想知道当 apache 使用 Py3 时错误会被修复。你呢？如何指定 Py3？

开始命令

# /etc/init.d/httpd restart

如果您正在使用已编译的 mod_wsgi，您需要针对您要使用的版本针对适当的 Python 二进制文件对其进行编译，否则它将默认为系统 Python 版本(通常仍为 2 .x，不幸的是)。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

祝你好运!
