Lvs/DR for CentOS+Windows2008r2

構(gòu)架：

控制器+ 2008web處理服務(wù)器

控制器管理IP1.1.1.1， 綁定vip1.1.1.250

webIP：RS1=192.168.228.219  RS2=192.168.228.220

一. Director Server調(diào)度器配置[系統(tǒng):Centos 6.4純凈班]

#修改hostname

#關(guān)閉防火墻

chkconfig iptables off

service iptables stop

#同步時(shí)間

yum install -y ntpdate

/usr/sbin/ntpdate cn.pool.ntp.org

crontab -e

二、Windows2008配置

創(chuàng)建windows環(huán)回網(wǎng)卡

  這是一樣很古老的東東了  打開(kāi) 設(shè)備管理器—選中‘網(wǎng)絡(luò)適配器’—操作---添加過(guò)時(shí)硬件

直接 下一步，

一直完成就OK；然后設(shè)置Ip

修改RS端網(wǎng)卡接口、環(huán)回接口連接模式（至關(guān)重要）

在cmd下

netsh interface ipv4 set interface "網(wǎng)卡名稱" weakhostreceive=enabled

netsh interface ipv4 set interface "網(wǎng)卡名稱" weakhostsend=enabled

netsh interface ipv4 set interface "環(huán)回網(wǎng)卡名稱" weakhostreceive=enabled

netsh interface ipv4 set interface "環(huán)回網(wǎng)卡名稱" weakhostsend=enabled

此處的網(wǎng)卡名稱要換為實(shí)例名稱本例中應(yīng)該是 “本地連接 11”(是外網(wǎng))或者“本地連接 9”(是內(nèi)網(wǎng))和“本地連接 12”

好了，配置沒(méi)有錯(cuò)誤的話用1.1.1.250 就可以訪問(wèn)了！！

RS為linux 的話配置就更簡(jiǎn)單 

ifconfig eth0:1.1.1.250 netmask 255.255.255.255 broadcast 1.1.1.250 up

route add -host 1.1.1.250 dev eth0:100

ipvsadm -C

ipvsadm -A -t 1.1.1.250:80 -s rr

ipvsadm -a -t 1.1.1.250:80 -r 192.168.228.220 -i

ipvsadm -a -t 1.1.1.250:80 -r 192.168.228.219 -i

ipvsadm

echo "0" >/proc/sys/net/ipv4/ip_forward

echo "1" >/proc/sys/net/ipv4/conf/all/send_redirects

echo "1" >/proc/sys/net/ipv4/conf/default/send_redirects

echo "1" >/proc/sys/net/ipv4/conf/eth0/send_redirects

RS1和RS2設(shè)置如下：

ifconfig tunl0 1.1.1.250 netmask 255.255.255.255 broadcast 1.1.1.250 up

route add -host 1.1.1.250 dev tunl0

echo "0" > /proc/sys/net/ipv4/ip_forward

echo 1 > /proc/sys/net/ipv4/conf/tunl0/arp_ignore

echo 2 > /proc/sys/net/ipv4/conf/tunl0/arp_announce

echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce

echo 0 > /proc/sys/net/ipv4/conf/tunl0/rp_filter

echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

若無(wú)法訪問(wèn)注意防火墻，可關(guān)閉！！
