LVS的简单配置

RIP1:193.168.120.101      HOST1RIP2:193.168.120.71        HOST2VIP:193.168.120.30LVS服务器执行的操作：LVS服务器ETH0接口的IP为：193.168.120.55

yum -y install ipvsadm

ipvsadm

lsmod | grep ip_vs

ifconfig eth0:1 193.168.120.30 broadcast 193.168.120.30 netmask 255.255.255.255 up

route add -host 193.168.120.30 dev eth0

ipvsadm -C

ipvsadm -A -t 193.168.120.30:80 -s rr -p 600

ipvsadm -a -t 193.168.120.30:80 -r 193.168.120.101:80 -g

ipvsadm -a -t 193.168.120.30:80 -r 193.168.120.71:80 -g

两台真实服务器上面分别执行：

ifconfig lo:0 193.168.120.30 netmask 255.255.255.255 uproute add -host 193.168.120.30 dev lo

待选：ARP抑制

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_announce

echo "2" > /proc/sys/net/ipv4/conf/all/arp_ignore
