LVS+Heartbeat安装部署文档

 所需软件:

ipvsadm- 1.24- 10.x86_64.rpm
heartbeat-2.1.3- 3.el5.centos.x86_64.rpm
heartbeat-pils-2.1.3- 3.el5.centos.x86_64.rpm
heartbeat-stonith-2.1.3- 3.el5.centos.x86_64.rpm
PyXML-0.8.4- 4.x86_64.rpm

系统环境:
CentOS 5.4 64-bit

HA1                    10.0.0.108
HA1                    10.0.0.109
web1                   10.0.0.110
web2                   10.0.0.111
VIP                    10.0.0.100

ipvsadm-1.24安装

rpm  -ivh ipvsadm- 1.24- 10.x86_64.rpm
/sbin /ipvsadm

heartbeat 安装

rpm  -ivh heartbeat-pils-2.1.3- 3.el5.centos.x86_64.rpm
rpm  -ivh heartbeat-stonith-2.1.3- 3.el5.centos.x86_64.rpm
rpm  -ivh PyXML-0.8.4- 4.x86_64.rpm
rpm  -ivh heartbeat-2.1.3- 3.el5.centos.x86_64.rpm

注:若heartbeat一次未安装好,再装一次

rpm  -q heartbeat -d               //查看安装路径

echo  "service heartbeat start"  > >  /etc /rc.local


配置heartbeat

cd  /usr /share /doc /heartbeat-2.1.3 /
cp authkeys ha.cf haresources  /etc /ha.d /
cd  /etc /ha.d
vi authkeys

#去掉注释      设置校验模式
auth  1
1 crc
#2 sha1 HI!
#3 md5 Hello!
echo  "10.0.0.108  HA1"  > > /etc /hosts
echo  "10.0.0.109  HA2"  > > /etc /hosts
vi haresources

#添加:(约44行下面)
HA1 10.0.0.100 vip.sh
vi ha.cf
#去掉注释(约95行)

bcast   eth0

#去掉注释并修改(约125行)

ucast eth0 10.0.0.109

#去掉注释并修改(约215、216行)

node    HA1
node    HA2
chmod  600 authkeys
vi  /etc /init.d /vip.sh
#/sbin/bash!
ifconfig eth0: 0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
route add  -host 10.0.0.100 dev eth0: 0
#setup ipvs
ipvsadm  -C
ipvsadm  -A  -t 10.0.0.100: 80  -s rr
ipvsadm  -a  -t 10.0.0.100: 80  -r 10.0.0.110  -g
ipvsadm  -a  -t 10.0.0.100: 80  -r 10.0.0.111  -g
ipvsadm

HA2的配置和HA1一样,可以直接上传HA1的authkeys ha.cf haresources三个文件

sftp 10.0.0.108

cd  /etc /ha.d
get authkeys ha.cf haresources
quit

修改HA2中ha.cf里(约125行)为:

ucast eth0 10.0.0.108

把vip.sh放到LVS服务器

vi  /etc /init.d /vip.sh            //放到这里开机自启动
chmod  755  /etc /init.d /vip.sh
/etc /init.d /vip.sh

echo  "service heartbeat start"  > >  /etc /rc.local

lvs.sh

#/sbin/bash!
ifconfig lo: 0 10.0.0.100 broadcast 10.0.0.100 netmask 255.255.255.255 up
route add  -host 10.0.0.100 dev lo: 0
echo  "1" > /proc /sys /net /ipv4 /conf /lo /arp_ignore
echo  "2" > /proc /sys /net /ipv4 /conf /lo /arp_announce
echo  "1" > /proc /sys /net /ipv4 /conf /all /arp_ignore
echo  "2" > /proc /sys /net /ipv4 /conf /all /arp_announce
sysctl  -p

web1  web2安装WEB服务

安装过程略

注:

lvs.sh放到WEB服务器

#vi /etc/init.d/lvs.sh           //放到这里开机自启动
#chmod 755 /etc/init.d/lvs.sh
#/etc/init.d/lvs.sh

得出结论:
不断刷新10.0.0.100,会轮流显示web1和web2页面
