LVS fullnat 从源码到安装

git clone https://github.com/alibaba/LVS.git[/code]放到/usr/src/下 
编译内核

yum install -y kernel-devel gcc
git branch -all
git checkout -b lvs_v2 origin/lvs_v2
cd LVS/kernel
vi .config
CONFIG_SYSFS_DEPRECATED=n
CONFIG_SYSFS_DEPRECATED_V2=n
make
make modules_install
make install


我在虚拟机中编译安装的，出现了一些声卡模块安装不上的问题，但不影响正常使用

配置grub.conf

vim /boot/grub/grub.conf
default=0
nohz=off
reboot


修改后内容如下：

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/sda3
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda

安装tools

安装keepalived

yum install -y openssl openssl-devel popt-devel
cd tools/keepalived
./configure --with-kernel-dir="/lib/modules/2.6.32/build"
make
make install
cp -a bin/keepalived /sbin/
cp -a keepalived/etc/init.d/keepalived.init /etc/init.d/keepalived
mkdir /etc/keepalived/
cp -a keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf
cp -a keepalived/etc/init.d/keepalived.sysconfig /etc/sysconfig/keepalived


安装ipvsadm

yum install -y libnl libnl-devel libssl-devel libssl popt popt-devel
cd  tools/ipvsadm
make
make install


修改/etc/sysctl.conf

vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
# configure for lvs
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.core.netdev_max_backlog = 500000


quagga安装，不建议使用源码包的源码安装，直接使用
yum install quagga


1). zebra配置

vi /etc/quagga/zebra.conf
hostname lvs-route-4
password 8 123456
enable password 8 123456
log file /var/log/zebra.log
service password-encryption
/usr/local/sbin/zebra -d -f /etc/quagga/zebra.conf


2). Ospf配置

hostname lvsdemo
password 8 123456
enable password 8 123456
log file /var/log/ospf.log
log stdout
log syslog
service password-encryption
interface eth0
ip ospf message-digest-key 8 md5 123456
ip ospf hello-interval 3
ip ospf dead-interval 12
