一、系統架構

二、部署過程

1、基於https://www.cnblogs.com/lybj/p/15008009.html的實現

2、配置router伺服器

2.1、在eth0網絡卡上增加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: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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伺服器

3.1、配置VIP

[root@rs1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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伺服器

4.1、新增VIP

同3.1

4.2、配置叢集

[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、驗證

[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
