问题描述
我在linux fedora30的apache服务器下运行Os.Popen和子进程有问题
当我在 apache 上部署 django 应用程序时，我无法在 apache 下使用 django 在 linux 中运行以下命令：
command2 = "[ -f /home/mohammad/file_sharing.txt ] || echo 'server IP: '%s'\n\nPath File:'%s'\n\nMount Point:'%s > /home/mohammad/file_sharing.txt " %(IP_Server_File_Sharing,Path_File_Sharing,Mount_Point)
k = os.popen(command2)
command1 = "[ -f /home/mohammad/file_sharing.txt ] && echo 'server IP: '%s'\n\nPath File:'%s'\n\nMount Point:'%s > /home/mohammad/file_sharing.txt " %(IP_Server_File_Sharing,Mount_Point)
k1 = os.popen(command1)
这些都是可以做的工作：
1.我使用 Fedora30
2.然后安装和更新 yum 和其他包，如以下命令：
百胜更新
sudo systemctl stop firewalld.service
yum install python-pip python-devel python3-pip python3-devel
pip3 install --upgrade pip
pip3 安装 virtualenv
dnf 安装 httpd
yum install python3-mod_wsgi.x86_64
3.然后创建一个目录并在虚拟环境中安装 Django：
mkdir /home/mohammad/myweb1
cd myweb1
virtualenv venv
source venv/bin/activate
4.然后 pip install 下面的包：
asgiref==3.3.1
Django==3.1.5
psycopg2-binary==2.8.6
python-pam==1.8.4
pytz==2020.5
sqlparse==0.4.1
5.然后配置django的其他设置：
django-admin startproject myproject
cd myproject
python manage.py startapp main
python manage.py collectstatic
python manage.py makemigrations
python manage.py migrate
6.现在配置 settings.py
在这 5 个步骤之后，我在 django 中配置了 settings.py：
ALLOWED_HOSTS = ['*']
STATIC_ROOT ='/home/mohammad/myweb1/myproject/main/static/'
7.在 /etc/httpd/conf.d/ 中创建 django.conf 文件并命名为 django.conf 的 apache 配置
<VirtualHost *:80>
Alias /static /home/mohammad/myweb1/myproject/main/static
<Directory /home/mohammad/myweb1/myproject/main/static>
Require all granted
</Directory>
<Directory /home/mohammad/myweb1/myproject/myproject>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIApplicationGroup %{GLOBAL}
WSGIDaemonProcess myproject python-path=/home/mohammad/myweb1/myproject python-
home=/home/mohammad/myweb1/venv
WSGIProcessGroup myproject
WSGIScriptAlias / /home/mohammad/myweb1/myproject/myproject/wsgi.py
</VirtualHost>
8.最后我运行以下命令：
setendorce 0
chown -R apache:apache /home/mohammad/myweb1
usermod -a -G mohammad apache
chmode -R 710 /home/mohammad
9. view.py 包：
from django.conf.urls import url
from django.shortcuts import render,get_object_or_404,redirect
from django.urls.base import resolve
from . models import Main
from django.contrib.auth import authenticate,login,logout,views
from django.http import HttpResponseRedirect
from django.urls import reverse
# import ntplib
from django.contrib.auth.models import User
from datetime import datetime,timezone
from time import ctime,sleep

import subprocess,shlex,tempfile
from subprocess import Popen
import re
from subprocess import STDOUT,check_output,PIPE

import logging

终于有人能帮我解决这个问题了吗？
我需要在 linux fedora30 的 apache 下在 django 中运行 Os.popen 和 subprocess
我可以通过启用 shell_exec 来解决这个问题吗？如何？或者如何解决权限拒绝 apache 访问以运行我的 linux 命令？
