位于2个网段的LVS的DR模型实验

实验规划说明:

Director两块网卡,IP地址分配如下:

1.本地公网IP(eth0):192.168.112.101

2.vip(eth1:1):192.168.112.100

3.dip(eth1):192.168.201.7

Realsever1两块网卡,IP地址分配如下:

1.rip(eth0):192.168.201.8

2.vip(lo:0):192.168.112.100

3.本地IP(eth1):192.168.112.8  //通过该IP以便从Realsever1可以访问Client.

Realsever2两块网卡,IP地址分配如下:

1.rip(eth0):192.168.201.9

2.vip(lo:0):192.168.112.100

3.本地IP(eth1):192.168.112.9  //通过该IP以便从Realsever1可以访问Client.

具体步骤如下:

1.配置realserver1的网络参数:

sysctl -p net.ipv4.conf.all.arp_ingore=1

sysctl -p net.ipv4.conf.eth0.arp_ingore=1

sysctl -p net.ipv4.conf.all.arp_announce=2

sysctl -p net.ipv4.conf.eth0.arp_announce=2

sysctl -p net.ipv4.ip_forward=1

若要上述信息永久生效需要写入/etc/sysctl.conf的配置文件.

ifconfig lo:0 192.168.112.100 broadcast 192.168.112.100 netmask 255.255.255.255 up

若要上述信息永久生效需要写入/etc/sysconfig/network-scripts/ifcfg-lo0的配置文件.

route add -host 192.168.112.100 dev lo:0

2.配置realserver2的网络参数:

sysctl -p net.ipv4.conf.all.arp_ingore=1

sysctl -p net.ipv4.conf.eth0.arp_ingore=1

sysctl -p net.ipv4.conf.all.arp_announce=2

sysctl -p net.ipv4.conf.eth0.arp_announce=2

sysctl -p net.ipv4.ip_forward=1

若要上述信息永久生效需要写入/etc/sysctl.conf的配置文件.

ifconfig lo:0 192.168.112.100 broadcast 192.168.112.100 netmask 255.255.255.255 up

若要上述信息永久生效需要写入/etc/sysconfig/network-scripts/ifcfg-lo0的配置文件.

route add -host 192.168.112.100 dev lo:0

3.配置director服务器:

sysctl -p net.ipv4.ip_forward=1

若要上述信息永久生效需要写入/etc/sysctl.conf的配置文件.

ifconfig eth1:1 192.168.112.100 broadcast 192.168.112.100 netmask 255.255.255.255 up

route add -host 192.168.112.100 dev eth1:1

4.配置lvs.

[[email protected] ~]# ipvsadm -A -t  192.168.112.100:80 -s rr

[[email protected] ~]# ipvsadm -a -t  192.168.112.100:80 -r 192.168.201.8 -g

[[email protected] ~]# ipvsadm -a -t  192.168.112.100:80 -r 192.168.201.9 -g

[[email protected] ~]# ipvsadm -Ln

IP Virtual Server version 1.2.1 (size=4096)

Prot LocalAddress:Port Scheduler Flags

-> RemoteAddress:Port           Forward Weight ActiveConn InActConn

TCP  192.168.112.100:80 rr

-> 192.168.201.8:80             Route   1      0          0

-> 192.168.201.9:80             Route   1      0          0

5.使用浏览器进行测试:

6.查看状态:

[[email protected] ~]# ipvsadm -Ln --stats

IP Virtual Server version 1.2.1 (size=4096)

Prot LocalAddress:Port               Conns   InPkts  OutPkts  InBytes OutBytes

-> RemoteAddress:Port

TCP  192.168.112.100:80                 53      271        0    28193        0

-> 192.168.201.8:80                   27      140        0    13983        0

-> 192.168.201.9:80                   26      131        0    14210        0

7.至此,基于2个网段的LVS的DR模型测试完成.
