fullnat开源已经有一阵子了,内核版本为2.6.32-220.23.1.e16,项目地址http://kb.linuxvirtualserver.org/wiki/IPVS_FULLNAT_and_SYNPROXY。本屌编译测试环境如下:
centos6.3 64位
编译过程参照官方做法,只是融入后续的打rpm包的部分。过程如下:
一、下载相关代码:
下载 kernel-2.6.32-220.23.1.el6.src.rpmlinux-2.6.32-220.23.1.el6.x86_64.lvs.src.tar.gz
二、编译内核
1、安装kernel-2.6.32-220.23.1.el6.src.rpm
1
|
rpm -ivh kernel-2.6.32-220.23.1.el6.src.rpm
|
2、生成内核源码
默认的,你会在root家目录下看到rpmbuild目
1
2
|
cd
~
/rpmbuild/SPECS
rpmbuild -bp kernel.spec
|
3、对生成的内核源码打patch默认的

#在/usr/local/src下解压linux-2.6.32-220.23.1.el6.x86_64.lvs.src.tar.gz
tar
zxf linux-2.6.32-220.23.1.el6.x86_64.lvs.src.
tar
.gz
#打patch
cd
~
/rpmbuild/BUILD/kernel-2
.6.32-220.23.1.el6
/linux-2
.6.32-220.23.1.el6.x86_64/
cp
/usr/local/src/linux-2
.6.32-220.23.1.el6.x86_64.lvs
/lvs-2
.6.32-220.23.1.el6.patch .
#淘宝将IP_VS改成了22,测试时遇到些麻烦,因此改为20了。
#vim .config
CONFIG_IP_VS_TAB_BITS=20
#你可以修改Makefile把内核的名称做下标记(line:4)
EXTRAVERSION = .FNAT.shanks.e27.x86_64
|
4、make
1
2
3
|
make
-j16
make
modules_install
make
install
;
|
5、配置grub.conf
1
2
|
#vim /boot/grub/grub.conf
default=0
|
三、reboot
reboot之后uname -r看下是不是你想要的内核。
四、打内核rpm包
1、安装kernel-2.6.32-220.23.1.el6.src.rpm
1
|
rpm -ivh
/usr/local/src/kernel-2
.6.32-220.23.1.el6.src.rpm
|
2、生成内核源码目录
1
|
rpmbuild -bp ~
/rpmbuild/SPECS/kernel
.spec
|
3、复制出一份内核源码目录
1
2
|
cd
~
/rpmbuild/BUILD/kernel-2
.6.32-220.23.1.el6/
cp
-a linux-2.6.32-220.23.1.el6.x86_64/ linux-2.6.32-220.23.1.el6.x86_64_new
|
4、为内核打fullnat的patch
1
2
3
|
cd
linux-2.6.32-220.23.1.el6.x86_64_new/
patch -p1 <
/usr/local/src/lvs-2
.6.32-220.23.1.el6.patch
cp
.config ~
/rpmbuild/SOURCES/config-x86_64-generic
|
5、删除原来内核源码目录中的.config文件。
1
2
|
cd
~
/rpmbuild/BUILD/kernel-2
.6.32-220.23.1.el6
/linux-2
.6.32-220.23.1.el6.x86_64
rm
-rf .config
|
不删的话,会在最后打rpm时遇到报错
6、打自己的patch
1
2
|
cd
~
/rpmbuild/BUILD/kernel-2
.6.32-220.23.1.el6/
diff
-uNr linux-2.6.32-220.23.1.el6.x86_64 linux-2.6.32-220.23.1.el6.x86_64_new/ > ../..
/SOURCES/lvs-2
.6.32-220.23.1.el6.patch
|
7、编辑kernel.spec
1
2
3
4
5
6
7
8
9
|
vim ~
/rpmbuild/SPECS/kernel
.spec
line:9 打上个版本号
%define dist .e27
line:22 打上个名称的标记
%define distro_build fnat.shanks
line:605 标记下自己的patch
Patch999999: lvs-2.6.32-220.23.1.el6.patch
line:915 让自己的patch生效
ApplyOptionalPatch lvs-2.6.32-220.23.1.el6.patch
|
8、打rpm
1
|
rpmbuild -bb --with baseonly --with firmware --without debuginfo --target=x86_64 SPECS
/kernel
.spec
|
1
2
3

在这里如果遇到这样的报错:
+
cp
/root/rpmbuild/SOURCES/Module
.kabi_x86_64
/root/rpmbuild/BUILDROOT/kernel-2
.6.32-fnat.shanks.e27.x86_64
/Module
.kabi
+
/root/rpmbuild/SOURCES/check-kabi
-k
/root/rpmbuild/BUILDROOT/kernel-2
.6.32-fnat.shanks.e27.x86_64
/Module
.kabi -s Module.symvers
*** ERROR - ABI BREAKAGE WAS DETECTED ***
The following symbols have been changed (this will cause an ABI breakage):
register_ip_vs_scheduler
unregister_ip_vs_scheduler
+
exit
1
error: Bad
exit
status from
/var/tmp/rpm-tmp
.0Wfj33 (%build)
RPM build errors:
Bad
exit
status from
/var/tmp/rpm-tmp
.0Wfj33 (%build)
可以在rpmbuild的时候加上--without kabichk
