클라이언트 브라우저에 응답하는 HTTP 서버(CentOS 7)에 Python 스크립트가 있는데 bash에서는 잘 작동하지만 cgi를 통해 액세스하려고 하면 오류가 발생합니다. Ubuntu에서는 HTTP와 쉘 모두를 통해 잘 작동합니다. 스크립트는 다음과 같습니다.
import socket
HOST = '127.0.0.1'
PORT = 4345
print("Content-type: text/html; charset=utf-8\n\n")
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((HOST, PORT))
query = 'foobar'
sock.sendall(bytes(query, 'utf-8'))
buffer = sock.recv(1024)
responce = str(buffer, "UTF-8")
print(responce)
CGI를 통해 스크립트를 실행할 때 발생하는 오류는 다음과 같습니다.
PermissionError: [Errno 13] Permission denied
Traceback (most recent call last):
File "/var/www/cgi-bin/script.py", line 8, in <module>
sock.connect((HOST, PORT))
PermissionError: [Errno 13] Permission denied
'getsebool -a | grep httpd'는 다음과 같습니다.

답변1
해결책은 httpd가 네트워크에 연결되도록 허용하는 것이었습니다. 방금 with 으로 httpd_can_network_connect
설정 했는데 작동이 시작되었습니다. 솔루션을 영구적으로 만들려면 스위치 도 사용해야 합니다.on
