重新编译内核之前，要保证根分区要有20G的内存。
如果没有足够的空间就添加一块20G的虚拟磁盘
1．给根分区分用lvm分20G的空间（如果有足够的空间，就不用做拉伸了）
[root@server6 ~]# fdisk -l #查看分区

2. 重新编译内核，将fallnat模块添加到在内核及测试
A）重新编译内核
[root@server6 mnt]# ls

[root@server6 mnt]# rpm -vih kernel-2.6.32-220.23.1.el6.src.rpm #安装内核包
[root@server6 mnt]# yum install rpm-build -y #安装rpmbuild
