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

|
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 |

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 |
