一、lvs-nat模式
网络配置:
lvs-server eth0 :host-only adapter 192.168.56.101
lvs-server eth1 :Internal 192.168.0.1
real-server-1 eth0:Internal 192.168.0.2
real-server-2 eth0:Internal 192.168.0.3
lvs-server:
1、安装ipvsadm软件
yum -y install ipvsadm*
echo 1 > /proc/sys/net/ipv4/ip_forward
路由器功能,ip转发
ipvsadm -C
ipvsadm -At 192.168.56.101:80 -s rr 轮叫模式
ipvsadm -at 192.168.56.101:80 -r 192.168.0.2 -m
ipvsadm -at 192.168.56.101:80 -r 192.168.0.3 -m
ipvsadm -L -n
2、real-server-1:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
route add default gw 192.168.0.1
3、real-server-2
ifconfig eth0 192.168.0.3 netmask 255.255.255.0
route add default gw 192.168.0.1
route -n 查看路由表
二、lvs-ipturn
网络配置:
lvs-server eth0:host-only adapter 192.168.56.101
real-server-1 eth0:host-only adapter 192.168.56.102
real-server-2 eth0:host-only adapter 192.168.56.103
lvs-server:
配置虚拟ip即vip
ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0</p> <p>ivsadm -C

ipvsadm -at 192.168.56.10:80 -r 192.168.56.102 -i
ipvsadm -at 192.168.56.10:80 -r 192.168.56.103 -i
ipvsadm -L -n
real-server-1:
ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0
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
real-server-2:
ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0
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
