　　可以采用如下办法解决：
　　vi keepalived-1.2.2/keepalived/libipvs-2.6/ip_vs.h
　　将以下行
#include <asm/types.h>          /* For __uXX types */
#include <linux/types.h>        /* For __beXX types in userland */
　　#include <netinet/in.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>
　　替换为以下行
#include <asm/types.h>          /* For __uXX types */
#include <sys/types.h>
#include <linux/types.h>        /* For __beXX types in userland */
　　#include <netinet/in.h>
#include <sys/socket.h>
#include <arpa/inet.h>
　　也就是将#include <sys/types.h>放到#include <linux/types.h>的前面
　　问题原因：循环引用问题。
