how to make a socket server listen on local file [closed]

Question

Just like MySQL server's /tmp/mysql.sock and client write to this file throught socket or any suggestion to share content between independent process (one update, one read) without memcached or NoSQL server, without multithread or multiprocess.

Answer 1

# Echo server program
import socket,os

s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
try:
    os.remove("/tmp/socketname")
except OSError:
    pass
s.bind("/tmp/socketname")
s.listen(1)
conn, addr = s.accept()
while 1:
    data = conn.recv(1024)
    if not data: break
    conn.send(data)
conn.close()


# Echo client program
import socket

s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
s.connect("/tmp/socketname")
s.send(b'Hello, world')
data = s.recv(1024)
s.close()
print('Received ' + repr(data))
