Redis默认配置中，客户端连接在长时间无操作后不会自动断开，但可以通过设置超时时间来调整这一行为。根据实际需求，你可以配置合适的超时时间以优化资源使用。

/* Check for timeouts. Returns non-zero if the client was terminated.
 * The function gets the current time in milliseconds as argument since
 * it gets called multiple times in a loop, so calling gettimeofday() for
 * each iteration would be costly without any actual gain. */
int clientsCronHandleTimeout(client *c, mstime_t now_ms) {
    time_t now = now_ms/1000;

    if (server.maxidletime &&
        !(c->flags & CLIENT_SLAVE) &&    /* no timeout for slaves */
        !(c->flags & CLIENT_MASTER) &&   /* no timeout for masters */
        !(c->flags & CLIENT_BLOCKED) &&  /* no timeout for BLPOP */
        !(c->flags & CLIENT_PUBSUB) &&   /* no timeout for Pub/Sub clients */
        (now - c->lastinteraction > server.maxidletime))
    {
        serverLog(LL_VERBOSE,"Closing idle client");
        freeClient(c);
        return 1;
    } else if (c->flags & CLIENT_BLOCKED) {
        /* Blocked OPS timeout is handled with milliseconds resolution.
         * However note that the actual resolution is limited by
         * server.hz. */

        if (c->bpop.timeout != 0 && c->bpop.timeout < now_ms) {
            /* Handle blocking operation specific timeout. */
            replyToBlockedClientTimedOut(c);
            unblockClient(c);
        } else if (server.cluster_enabled) {
            /* Cluster: handle unblock & redirect of clients blocked
             * into keys no longer served by this server. */
            if (clusterRedirectBlockedClientIfNeeded(c))
                unblockClient(c);
        }
    }
    return 0;
}

# Close the connection after a client is idle for N seconds (0 to disable)
timeout 0

在server.c里面能看到上面代码客户端配置文件 redis.conf可以设置超时时间

如果登陆长时间没有输入命令会有超时现象默认的配置文件是0 是一直保持连接

可以根据自己的需求设置
