python redis连接池sub/pub断开连接问题

单机redis服务器没有出现断开连接问题

云服务集群版本出现了

尝试解决

连接池设置探测活性

其中参数解释如下

int fd = tcpSocket->socketDescriptor();
int keepAlive = 1;      //开启keepalive属性,缺省值:0(关闭)
int keepIdle = 5;       //如果在5秒内没有任何数据交互,则进行探测,缺省值:7200(s)
int keepInterval = 2;   //探测时发探测包的时间间隔为2秒,缺省值:75(s)
int keepCount = 2;      //探测重试的次数,全部超时则认定连接失效,缺省值:9(次)
setsockopt(fd, SOL_SOCKET, SO_KEEPALIVE, (void *)&keepAlive, sizeof(keepAlive));
setsockopt(fd, SOL_TCP, TCP_KEEPIDLE, (void *)&keepIdle, sizeof(keepIdle));
setsockopt(fd, SOL_TCP, TCP_KEEPINTVL, (void *)&keepInterval, sizeof(keepInterval));
setsockopt(fd, SOL_TCP, TCP_KEEPCNT, (void *)&keepCount, sizeof(keepCount));
