在 debian 8.11 上为 flask 1.0.3 配置 Apache/2.4.10 mod_wsgi 和 virtualenv python 3.6

Question

我的 apache 配置文件有：

<VirtualHost *:80> 

ServerName localhost
WSGIDaemonProcess tasks4 python-path=/home/user1/Projects/tasks/tasks/tasks/wsgi.py:/home/user1/env_rt_dms:/home/user1/env_rt_dms/lib/python3.6/site-packages
WSGIScriptAlias / /home/user1/Projects/tasks/tasks/tasks/wsgi.py

WSGIPassAuthorization On

Alias /rt1 /home/user1/Projects/tasks/tasks/tasks/static/

<Directory /home/user1/Projects/tasks/tasks>
    DirectoryIndex index.html
    WSGIProcessGroup tasks4
    WSGIApplicationGroup %{GLOBAL}
    WSGIScriptReloading On
    Require all granted
</Directory>
</VirtualHost>

wsgi 文件：

#! /home/user1/env_rt_dms/bin
import sys, os

activate_this = '/home/user1/env_rt_dms/bin/activate_this.py'
with open(activate_this) as file_:
    exec(file_.read(), dict(__file__=activate_this))

os.environ['DB_URL']="postgresql://usernm:passwd1@localhost:5432/my_db"

from tasks import app as application
application.secret_key = '\x04\xf5\\VN:\xb7\xb9\xca\x95\xa3m!4@\x17\xfcg\xe5\xe2q\x05'

激活apache web服务器后的浏览器url：http://localhost/rt1给出404错误

apache 日志显示：mod_wsgi: Compiled for Python/3.4.2 作为警告。请让我知道我需要解决什么问题才能使此配置正常工作？

应该设置WSGIDaemonProcess指令的python-home选项。

激活您在终端中安装了mod_wsgi 的虚拟环境。

在终端中运行命令python -c "import sys; print(sys.prefix)"，复制输出，并将其设置为python-home选项。

WSGIDaemonProcess tasks4 python-path=/home/user1/Projects/tasks/tasks/tasks python-home=<sys_prefix_value_in_virtual_env>

删除wsgi.py模块中手动激活虚拟环境。

#!/usr/bin/env python

import sys, os

os.environ['DB_URL']="postgresql://usernm:passwd1@localhost:5432/my_db"

from tasks import app as application
application.secret_key = '\x04\xf5\\VN:\xb7\xb9\xca\x95\xa3m!4@\x17\xfcg\xe5\xe2q\x05'

查看python-path 选项并确保/home/user1/Project/tasks/tasks/tasks 是您项目的根文件夹。
