刚在一台IBM Xserver服务器上装了RedHat Linux Enterprise AS 4，为了提高网络的可靠性配置双网卡绑定。
一、环境描述
我的RedHat Linux Enterprise AS 4安装双口的Intel千兆网卡，通过ifconfig -a命令看到eth0和eth1两张网卡。
二、双网卡绑定步骤：
2.1 修改/etc/sysconfig/network
1.AdviceMethods.java
package com.bijian.study.spring.aop.schema;
public class AdviceMethods {
public void preGreeting() {
System.out.println("--how are you!--");
}
}
2.beans.x
包括Spark Streaming在内的实时计算数据可靠性指的是三种级别：
1. At most once，数据最多只能接受一次，有可能接收不到
2. At least once, 数据至少接受一次，有可能重复接收
3. Exactly once 数据保证被处理并且只被处理一次，
具体的多读几遍http://spark.apache.org/docs/lates
