关于redis空闲过长事件连接断开问题

我有一个cli脚本，需要长时间执行，用redis加锁，但是执行时间很长，等到解锁的时候，redis连接已经断开了，然后报错了用的phpredis.
host: string. can be a host, or the path to a unix domain socket. Starting from version 5.0.0 it is possible to specify schema
port: int, optional
timeout: float, value in seconds (optional, default is 0 meaning it will use default_socket_timeout)
reserved: should be ‘’ if retry_interval is specified
retry_interval: int, value in milliseconds (optional)
read_timeout: float, value in seconds (optional, default is 0 meaning it will use default_socket_timeout)
others: array, with PhpRedis >= 5.3.0, it allows setting auth and stream configuration.
下面是phpredis的参数，怎么可以设置让连接不会自动断开？
