NAT模式实验:
CIP:192.168.100.101/24(vmnet5)
VIP:192.168.100.100/24(vmnet5)
DIP:172.16.100.1/16/eth0 (vmnet1)
RIP1:172.16.100.15/16/eth0(vmnet1)
RIP2:172.16.100.16/16/eth0(vmnet1)
RS上的操作:
准备httpd服务,并且准备不同的页面。
设定RS的网关指向DIP
Director上的操作:
# vim /etc/sysctl.conf
net.ipv4_forword = 1
# sysctl -p
# ipvsadm -A -t 192.168.100.100:80 -s rr
# ipvsadm -a -t 192.168.100.100:80 -r 172.16.100.15 -m
# ipvsadm -a -t 192.168.100.100:80 -r 172.16.100.16 -m
# ipvsadm -Ln --stats
客户端的操作:
# elinks http://192.168.100.100/index.html
DR模型:
(1)当VIP和DIP、RIP在同一个网段内时:
Director:
DIP:172.16.100.1/16/eth0
VIP:172.16.100.11/32/eth0:0
RS1:
RIP:172.16.100.15/16/eth0
VIP:172.16.100.11/32/lo
RS2:
RIP:172.16.100.16/16/eth0
VIP:172.16.100.11/32/lo
CIP:172.16.100.101/16
RS1上的操作:
# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
# ifconfig lo:0 172.16.100.11 broadcast 172.16.100.11 netmask 255.255.255.255 up
# route add -host 172.16.100.11 dev lo:0(使得数据报文无论从哪个网卡出去,IP地址都是VIP)
RS2上的操作同上,而且准备不同的web页面。
Director上的操作:
# ifconfig eth0:0 172.16.100.11 broadcast 172.16.100.11 netmask 255.255.255.255 up
# ipvsadm -A -t 172.16.100.11:80 -s rr
# ipvsadm -a -t 172.16.100.11:80 -r 172.16.100.15 -g
# ipvsadm -a -t 172.16.100.11:80 -r 172.16.100.16 -g
客户端操作:
# elinks http://172.16.100.11/index.html(此时Director上无法访问)
(2)当VIP和DIP、RIP不在同一个网段内时:
Director:
DIP:172.16.100.1/16/eth0
VIP:192.168.100.11/32/eth0:0
RS1:
RIP:172.16.100.15/16/eth0
VIP:192.168.100.11/32/lo
RS2:
RIP:172.16.100.16/16/eth0
VIP:192.168.100.11/32/lo
CIP:172.16.100.101/16
RS1上的操作:
# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
# ifconfig lo:0 192.168.100.11 broadcast 192.168.100.11 netmask 255.255.255.255 up
# route add default gw 172.16.100.17
# route add -host 192.168.100.11 dev lo:0
添加RS的网关设备:
# ifconfig eth0 172.16.100.17
# ifconfig eth0:0 192.168.100.17
# vim /etc/sysctl.conf
net.ipv4_forword = 1
# sysctl -p
#如果可能的话还可以给这个路由设备添加一个网关
