封装带SSH跳板机的REDIS

一、封装ssh的redis

二、setting的配置

三、应用示例

import redis
from sshtunnel import SSHTunnelForwarder
from conf.setting import REDIS_online, REDIS_dev

class MyRedis():

    def __del__(self):
        self.server.close()    

    def __init__(self,host,ip,ssh_username,ssh_password,db,password):
        #构造shh-redis链接，使用setting配置文件
        try:
            server = SSHTunnelForwarder(
                ssh_address_or_host=(host, 22),
                ssh_username=ssh_username,
                ssh_password=ssh_password,
                remote_bind_address=(ip, 6379)
            )
            self.server = server
            self.server.daemon_forward_servers = True #不加server关闭不了
            self.server.start()

    #         return 0
