LVS fullnat安裝

阿里巴巴開源LVS fullnat  （內核要求2.6.32）

1、下載 fullnat LVS源碼

wget https://github.com/alibaba/LVS/tree/lvs_v2               #版本2，建議使用這個版本

wget https://github.com/alibaba/LVS/archive/master.zip

unzip aster.zip;  #解壓下載的源碼，主要有以下文件目錄，其中 kernel目錄是內核源碼，tools里有ipvsadm 、keepalived、quagga（可以使用Quagga將linux機器打造成一臺功能完備的路由器）、rpm

2、內核編譯&安裝

cd  /usr/local/src/LVS-lvs_v2/kernel

請先安裝好 perl perl-devel popt popt-devel libnl libnl-devel libssl libssl-devel openssl openssl-devel popt-static yum -y install ncurses ncurses-devel

去 掉 udev，udev的編譯要求比較嚴格，容易在啟動時報udev: missing sysfs features; please update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED option;出現這個錯問題也不大

vi .config

CONFIG_SYSFS_DEPRECATED=n

CONFIG_SYSFS_DEPRECATED_V2=n

mkdir -p /usr/src/kernels/2.6.32

make O=/usr/src/kernels/2.6.32 menuconfig;   #選擇模塊需要編譯的，exit退出，選擇 YES保存

make mrproper

make O=/usr/src/kernels/2.6.32

make O=/usr/src/kernels/2.6.32 modules_install install

make時遇錯

/bin/sh: perl: command not found

make[2]: *** [scripts/mod/empty.o] Error 127

make[1]: *** [scripts/mod] Error 2

make: *** [scripts] Error 2

解決：yum -y perl perl-devel

make install遇錯

WARNING: Couldn't open directory /lib/modules/2.6.32: No such file or directory

解決：ln -s /lib/modules/`uname -r` /lib/modules/2.6.32

問題：make install時報

sh /usr/local/src/LVS-lvs_v2/kernel/arch/x86/boot/install.sh 2.6.32 arch/x86/boot/bzImage \

                System.map "/boot"

ERROR: modinfo: could not find module sd_mod

ERROR: modinfo: could not find module crc_t10dif

解答：這是因為現在運行的kernel有這些模塊，而新編譯的內核沒有這些模塊。如果不需要可直接忽視，如果需要編譯到新的內核中，請修改 .config的相關參數為=m

使用新編譯的內核vi /boot/grub/grub.conf 修改

default=0

reboot 重啟系統，uname -r查看到的版本應該是2.6.32

3、安裝keepalived

要求先安裝好 openssl openssl-devel popt-static 

cd  /usr/local/src/master/tools/keepalived/

./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/local/src/LVS-lvs_v2/kernel;

make;

最終結果：

Keepalived configuration

------------------------

Keepalived version       : 1.2.2

Compiler                 : gcc

Compiler flags           : -g -O2

Extra Lib                : -lpopt -lssl -lcrypto  -lnl

Use IPVS Framework       : Yes

IPVS sync daemon support : Yes

IPVS use libnl           : Yes

Use VRRP Framework       : Yes

Use Debug flags          : No

make install;

默認路徑： /usr/local

配置文件： /usr/local/etc/keepalived/keepalived.conf

自動啟動腳本模板： /usr/local/etc/rc.d/init.d/keepalived

復制安裝目錄下的 /usr/local/keepalived/etc/rc.d/init.d/keepalived 復制到 /etc/init.d/

把/etc/init.d/keepalived  文件中

. /etc/sysconfig/keepalived 改為  

. /usr/local/keepalived/etc/sysconfig/keepalived

keepalived啟動時報 Starting keepalived: /bin/bash: keepalived: command not found

解決方法：  ln -s prefix/sbin/keepalived /usr/sbin/

4、安裝ipvsadm

依賴 libnl libnl-devel  libssl-devel libssl

cd /usr/local/src/LVS-lvs_v2/tools/ipvsadm/

make;

make install;

make遇錯

gcc -Wall -Wunused -Wstrict-prototypes -g -o ipvsadm ipvsadm.o config_stream.o dynamic_array.o ../keepalived/keepalived/libipvs-2.6/libipvs.a -lpopt  -lnl

/usr/bin/ld: cannot find -lnl

collect2: ld returned 1 exit status

make: *** [ipvsadm] Error 1

解決：yum -y install libnl libnl-devel  libssl-devel libssl

5、安裝quagga

cd /usr/local/src/LVS-lvs_v2/tools/quagga

./configure --prefix=/usr/local/quagga

make;

make install;
