2. TCP keepalive overview In order to understand what TCP keepalive (which we will just call keepalive) does, you need do nothing more than read the name: keep TCP alive. This means that you will be able to check your connected socket (also known as…

之前一直对tcp keepalive选项理解有误, 以为通过setsockopt函数设置SO_KEEPALIVE和相关参数后该socket则使用设置的keepalive相关参数 否则使用系统默认的:keepalive配置(如下) root@xxx-KVM:/# sysctl -a | grep keepnet.ipv4.tcp_keepalive_intvl = 30net.ipv4.tcp_keepalive_probes = 9net.ipv4.tcp_keepalive_time = 90…

Linux has built-in support for keepalive. You need to enable TCP/IP networking in order to use it. You also need procfs support and sysctl support to be able to configure the kernel parameters at runtime. The procedures involving keepalive use three…

这篇文章是我来Hulu这一年做的主要工作,结合当下流行的两个开源方案Docker和YARN,提供了一套灵活的编程模型,目前支持DAG编程模型,将会支持长服务编程模型. 基于Voidbox,开发者可以很容易的写出一个分布式的框架,Docker作为运行的执行引擎,YARN作为集群资源的管理系统. 同时这篇文章也发表在Hulu官方的技术博客上:http://tech.hulu.com/blog/2015/08/06/voidbox-docker-on-yarn/ csdn在线:http://huiyi…
