Using a imported module in python result in permission denied error
Question
I'm trying to use a imported module (pylightning) in a python script that runs using apache under user www-data.
The script gives a permission error when run via apache as user www-data:
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 69, in call
sock.connect(self.socket_path)
PermissionError: [Errno 13] Permission denied
To fix this I have intensively searched and found i needed to reinstall the module as www-data user:
sudo pip3 uninstall pylightning
sudo -H -u www-data pip3 install pylightning
The script still runs smoothly from the CLI as regular user:
$python3 index.py
Content-Type: text/html
<html><body>
etc...
But from apache (through a browser or from the command line as user www-data) still gives the same error:
$sudo -u www-data python3 /var/www/html/index.py
Content-Type: text/html
<html><body>
Traceback (most recent call last):
File "/var/www/html/index.py", line 29, in <module>
print(rpc_interface.listpeers())
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 345, in listpeers
return self.call("listpeers", payload)
File "/usr/local/lib/python3.4/dist-packages/lightning/lightning.py", line 69, in call
sock.connect(self.socket_path)
PermissionError: [Errno 13] Permission denied
Anyone has any idea here?
Script source:
#!/usr/bin/env python3
import hashlib
from lightning.lightning import LightningRpc
rpc_interface = LightningRpc("/home/pi/.lightning/lightning-rpc")
print ("Content-Type: text/html\n\n");
print ("</body></html>asd");
print(rpc_interface.listpeers())
the error triggers on this line: print(rpc_interface.listpeers())

验证www数据用户是否有权访问/home/pi/.lightning/lightning-rpc （包括父目录）。
