LVSDR模式多网段的实现

1、基于https://www.cnblogs.com/lybj/p/15008009.html的实现

2、配置router服务器

2.1、在eth0网卡上增加ip

[19:27:42 root@router ~]#ip a a 172.16.0.200/24 dev eth0:1
[19:32:32 root@router ~]#ip a
1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:fc:02:d2 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.200/24 brd 10.0.0.255 scope global noprefixroute eth0
valid_lft forever preferred_lft forever
inet 172.16.0.200/24 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fefc:2d2/64 scope link
valid_lft forever preferred_lft forever
3: eth1: mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:fc:02:dc brd ff:ff:ff:ff:ff:ff
inet 192.168.10.200/24 brd 192.168.10.255 scope global noprefixroute eth1
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fefc:2dc/64 scope link
valid_lft forever preferred_lft forever

3、配置RS服务器

3.1、配置VIP

[root@rs1 ~]# ip a
1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet 172.16.0.100/32 scope global lo:1
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 00:0c:29:15:5b:55 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.7/24 brd 10.0.0.255 scope global noprefixroute eth0
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fe15:5b55/64 scope link
valid_lft forever preferred_lft forever

4、配置LVS服务器

4.1、添加VIP

同3.1

4.2、配置集群

[18:27:35 root@lvs ~]#ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 172.16.0.100:80 wrr
-> 10.0.0.7:80 Route 1 0 0
-> 10.0.0.17:80 Route 1 0 0

5、验证

[18:33:57 root@internet ~]#curl 172.16.0.100
rs2 10.0.0.17
[18:34:25 root@internet ~]#curl 172.16.0.100
rs1 10.0.0.7
[18:34:27 root@internet ~]#curl 172.16.0.100
rs2 10.0.0.17
[18:34:28 root@internet ~]#curl 172.16.0.100
rs1 10.0.0.7
[18:34:29 root@internet ~]#curl 172.16.0.100
rs2 10.0.0.17
