protected void config(ServerBootstrap bootstrap) throws Exception{
        //允许在同一端口上启动同一服务器的多个实例，只要每个实例捆绑一个不同的本地IP地址即可
        bootstrap.option(ChannelOption.SO_REUSEADDR, true)
                //netty boos的默认内存分配器
//                    .option(ChannelOption.ALLOCATOR, ByteBufAllocatorX.INSTANCE)
                //用于构造服务端套接字ServerSocket对象，标识当服务器请求处理线程全满时，用于临时存放已完成三次握手的请求的队列的最大长度
//                    .option(ChannelOption.SO_BACKLOG, 1024) // determining the number of connections queued

                //禁用Nagle算法，即数据包立即发送出去 (在TCP_NODELAY模式下，假设有3个小包要发送，第一个小包发出后，接下来的小包需要等待之前的小包被ack，在这期间小包会合并，直到接收到之前包的ack后才会发生)
//                    .childOption(ChannelOption.TCP_NODELAY, true)
                //开启TCP/IP协议实现的心跳机制
                .childOption(ChannelOption.SO_KEEPALIVE, true)
                //netty的work默认内存分配器
                .childOption(ChannelOption.ALLOCATOR, ByteBufAllocatorX.INSTANCE);
//              .childOption(ChannelOption.ALLOCATOR, ByteBufAllocator.DEFAULT);

        if(enableEpoll){
            //允许使用同一个端口, 内核实现的负载均衡. 需要 Linux kernel >= 3.9
            bootstrap.option(UnixChannelOption.SO_REUSEPORT, true);
        }
    }
