PHP exec(python.py),权限被拒绝写入文件
我试图使用PHP的exec()函数执行python脚本。PHP exec(python.py),权限被拒绝写入文件
的PHP页面加载在浏览器:
<?php
echo exec("whoami");
echo(exec("/bin/python2.7 /var/www/cgi-bin/api/download.py"));
?>
下面是python脚本:如果执行的.py或.PHP作为Apache用户

from oauth2client.file import Storage
from apiclient.discovery import build
from oauth2client.client import OAuth2WebServerFlow
from apiclient.http import MediaIoBaseDownload
from oauth2client.service_account import ServiceAccountCredentials
scopes = ['https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name('/opt/scripts/full-patator-preprod.json', scopes)
delegated_credentials = credentials.create_delegated('#############')
http_auth = delegated_credentials.authorize(Http())
drive_service = build('drive', 'v2', http=http_auth)
def get_file(service,fileId):
file = service.files().get(fileId=fileId).execute(http=http_auth);
return file
item = get_file(drive_service,"#############")
print(item.get('title'))
delegated_credentials = credentials.create_delegated("#############")
http_auth = delegated_credentials.authorize(Http())
request = drive_service.files().export_media(fileId="#############", mimeType='application/pdf')
fh = io.FileIO("api/test.pdf","wb")
downloader = MediaIoBaseDownload(fh, request)
done = False
counter=0;
while done is False:
status, done = downloader.next_chunk()
print "Download %d%%." % int(status.progress() * 100)
counter+=1
if counter > 10:
done=True
with open("test.pdf") as f: ## PDF File
print(type(f)) ## Open file is TextIOWrapper
bw=io.TextIOWrapper(fh) ## Conversion to TextIOWrapper
print(type(bw)) ## Just to confirm
一切正常。 但是用我的浏览器,当它涉及到写入文件:
fh = io.FileIO("api/test.pdf","wb")
我有这个输出在我的Apache的error_log:
Traceback (most recent call last): File "/var/www/cgi-bin/api/download.py", line 46, in fh = io.FileIO("test.pdf","wb") IOError: [Errno 13] Permission denied: 'test.pdf'
好吧,我敢肯定,这是由于权限父文件夹,然后是父项的父项权限。但我对这些文件夹设置了777权限,它什么也没做。
我的PHP脚本是在/var/www/html/manager/execute.php 我的.py脚本在/var/www/cgi-bin/api/download.py
文件夹/ WWW/,/ cgi-bin /,/ api /拥有777个权限。
我知道这不是一个好习惯,但我想在做一些更干净的事情之前解决这个问题。
在此先感谢
您是否尝试禁用SELinux?

你好克里斯托弗, 我只是试过了,现在,我没有任何权限输出错误,但没有任何反应..和我的脚本超时 –
如果你调用PHP文件在浏览器中的你将成为用户'WWW-data'。而普通的'www-data'在命令行上不应该拥有太多的权限。 – JustOnUnderMillions
PHP脚本以谁的身份运行?该用户/组是否有权运行Python脚本? –
你好,我可以假设PHP运行为Apache用户,因为当我执行: shell_exec(“whoami”); 它返回我“apache” 当然,apache是.py文件的所有者 –
