python 實現類似tweproxy 和codes的功能的redis代理功能

手動編寫redis代理軟件腳本  實現類似tweproxy  和codes的功能

已經實現內容如下：

 起1個代理ip和端口  redisl客戶端連接代理  然後腳本通過一致性hash分發key到後端的redis

腳本如下

import SocketServer,sys
from threading import Thread
import socket
from hash_ring import HashRing

redis_servers = ['127.0.0.1:6480',
                 '127.0.0.1:6481',
                 '127.0.0.1:6482']
 
ring = HashRing(redis_servers)

class service(SocketServer.BaseRequestHandler):
    def handle(self):
        data = 'dummy'
        print "Client connected with ", self.client_address
        while len(data):
            data = self.request.recv(1024)
	    if data:
	        key =(data.split("\n"))[4]
		server = ring.get_node(key)
		s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)      
		s.connect(((server.split(":"))[0],int((server.split(":"))[1])))
	        s.sendall(data)
		r_data  = s.recv(1024)
		print server
            self.request.send(r_data)

        print "Client exited"
        self.request.close()


class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
    pass
try:
    t = ThreadedTCPServer(('',6379), service)
    t.serve_forever()
except KeyboardInterrupt:
    sys.exit(1)
