lvs fullnat+ECMP【1】內核編譯

python wget ros onf driver sym lpc quit mac 0、請使用物理機安裝，虛擬機沒編譯成功
1、先查看一下系統版本，需要是centos6，內核2.6
cat /etc/*release uname -r
[root@lvs-fullnat-one ~]# cat /etc/*release CentOS release 6.5 (Final) LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch CentOS release 6.5 (Final) CentOS release 6.5 (Final) [root@lvs-fullnat-one ~]# uname -r 2.6.32-431.el6.x86_64 [root@lvs-fullnat-one ~]#
2、從Redhat網站下載kernel的rpm
wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/kernel-2.6.32-220.23.1.el6.src.rpm
如果無法現在，請從網盤下載。連接：

3、從rpm中獲得kerel源碼
vim ~/.rpmmacros; add: %_topdir /home/pukong/rpms %_tmppath /home/pukong/rpms/tmp %_sourcedir /home/pukong/rpms/SOURCES %_specdir /home/pukong/rpms/SPECS %_srcrpmdir /home/pukong/rpms/SRPMS %_rpmdir /home/pukong/rpms/RPMS %_builddir /home/pukong/rpms/BUILD cd /home/pukong; mkdir rpms; mkdir rpms/tmp; mkdir rpms/SOURCES; mkdir rpms/SPECS; mkdir rpms/SRPMS; mkdir rpms/RPMS; mkdir rpms/BUILD; useradd mockbuild rpm -ivh kernel-2.6.32-220.23.1.el6.src.rpm cd /home/pukong/rpms/SPECS yum -y install rpm-build yum -y install gcc zlib-devel patchutils xmlto asciidoc elfutils-libelf-devel binutils-devel newt-devel python-devel hmaccalc yum -y install rng-tools openssl-devel rngd -r /dev/urandom ##rng-tools用於在執行rpmbuild -bb --target=`uname -m` kernel.spec的時候生成隨機數，不然會卡在那裏，但是根據卡的地方倒退回去會看到提示就執行rngd -r /dev/hwrandom，不行的話執行 rngd -r /dev/urandom，因此需要安裝此工具 rpmbuild -bp kernel.spec;
最後的rpmbuild是一個可能是一個十分漫長的操作,請不要關閉xshell。
這時候你就能在/home/pukong/rpms/BUILD找到內核源碼
[root@lvs-fullnat-one SPECS]# cd /home/pukong/rpms/BUILD/;
[root@lvs-fullnat-one BUILD]# ls
kernel-2.6.32-220.23.1.el6
4、添加lvs patch
[Lvs-fullnat-synproxy.tar.gz]
https://pan.baidu.com/s/1sOnbGpnk7vZGoTxgEVDpAA
將文件放到服務器中
tar xvf Lvs-fullnat-synproxy.tar.gz cd lvs-fullnat-synproxy/ cp lvs-2.6.32-220.23.1.el6.patch /home/pukong/rpms/BUILD/kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64/ cd /home/pukong/rpms/BUILD/; cd kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64/; patch -p1<lvs-2.6.32-220.23.1.el6.patch; // patch is in lvs-fullnat-synproxy.tar.gz 給內核打補丁 補丁不能重復打
打完補丁，修改Makefile文件，給內核版本命名：
[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]# uname -r
2.6.32-431.el6.x86_64
[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]# vim Makefile
將Makefile中EXTRAVERSION 字段補上一個跟uname -r相似字段，如下圖
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 32
EXTRAVERSION = -431.toa.el6.x86_64
NAME = Man-Eating Seals of Antiquity
RHEL_MAJOR = 6
RHEL_MINOR = 2
RHEL_RELEASE = 219
註意修改.config文件中的參數,主要是為了擴大VS最大連接數，可以增大VS的吞吐量（並發連接量），如果值只是原本的4096可能會丟包
vim .config
CONFIG_IP_VS_TAB_BITS=22 5、編譯內核
make -j16 ##j是指同時作業的數量，可以不用添加此參數
make modules_install;
make install;此時可能會報幾個錯
[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]# make install;
sh /home/pukong/rpms/BUILD/kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64/arch/x86/boot/install.sh 2.6.322.6.32-431.el6.x86_64 arch/x86/boot/bzImage System.map "/boot"
ERROR: modinfo: could not find module lpc_ich
ERROR: modinfo: could not find module ptp
[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]#
需要復制進來幾個模塊
cp /lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/mfd/lpc_ich.ko /lib/modules/2.6.32-431.toa.el6.x86_64/kernel/drivers/mfd/
mkdir /lib/modules/2.6.32-431.toa.el6.x86_64/kernel/drivers/ptp
cp /lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/ptp/ptp.ko /lib/modules/2.6.32-431.toa.el6.x86_64/kernel/drivers/ptp/
重新安裝,會有幾個警告，忽略即可
[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]# make install;
sh /home/pukong/rpms/BUILD/kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64/arch/x86/boot/install.sh 2.6.32-431.toa.el6.x86_64 arch/x86/boot/bzImage System.map "/boot"
WARNING: /lib/modules/2.6.32-431.toa.el6.x86_64/kernel/drivers/ptp/ptp.ko needs unknown symbol kmem_cache_alloc_trace
WARNING: /lib/modules/2.6.32-431.toa.el6.x86_64/kernel/drivers/ptp/ptp.ko needs unknown symbol posix_clock_register

[root@lvs-fullnat-one linux-2.6.32-220.23.1.el6.x86_64]# 6、修改內核文件
vim /boot/grub/grub.conf
修改default的值為0 表示先啟動
引導文件中有兩個引導啟動段，一個是原本內核的linux，一個是新編譯的內核，新編譯的內核在上面，所以把default的值設為0，即表示使用新的內核引導系統了。
7、重啟
reboot
