手动编写redis代理软件脚本 实现类似tweproxy 和codes的功能
已经实现内容如下:
起1个代理ip和端口 redisl客户端连接代理 然后脚本通过一致性hash分发key到后端的redis
脚本如下
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)
python 实现类似tweproxy 和codes的功能的redis代理功能
