也不是不可以, 如果是socket的话只要设置端口复用就可以实现，随便写一段代码演示一下

#/bin/python

import sys

import time

import socket

def start_tcp_client(ip, port):

#server port and ip

server_ip = ip

servr_port = port

tcp_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 设置端口复用和地址复用

tcp_client.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

tcp_client.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)

tcp_client.bind(('0.0.0.0', 23333))

tcp_client.connect((server_ip, servr_port))

# 没啥意义地一直接收数据

while True:

print tcp_client.recv(1024)

time.sleep(1)

ip = sys.argv[1]

port = int(sys.argv[2])

start_tcp_client(ip, port)

然后启动两个进程连接不同的数据库
