Linux Test setup, it has been tested on
- Debian 8
- Apache 2.4
- Hostname used for the test: myLVS-LinuxClient
System settings to configure the loop back adapter
Edit /etc/sysctl.conf and add:
net.ipv4.conf.eth0.arp_ignore = 1 net.ipv4.conf.eth0.arp_announce = 2 net.ipv4.conf.all.arp_ignore = 1 net.ipv4.conf.all.arp_announce = 2
Either unload your network adapter and apply the above settings or simply reboot.
Add to /etc/rc.local to automatic load the loop back adapter:
/sbin/ifconfig lo:0 192.168.2.220 -arp netmask 255.255.255.255 up
ifconfig should look like:
root@myLVS-LinuxClient:~# ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:89:f3:8d inet addr:192.168.2.222 Bcast:255.255.255.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe89:f38d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1646 errors:0 dropped:2 overruns:0 frame:0 TX packets:356 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:153233 (149.6 KiB) TX bytes:105801 (103.3 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:32 errors:0 dropped:0 overruns:0 frame:0 TX packets:32 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1920 (1.8 KiB) TX bytes:1920 (1.8 KiB) lo:0 Link encap:Local Loopback inet addr:192.168.2.220 Mask:255.255.255.255 UP LOOPBACK RUNNING MTU:65536 Metric:1
Testing the loop back adapter
Switch off the first (Windows) client
The new myLVS overview should now show the disabled server marked with a red cross:
Use a network client and open the URL http://192.168.2.220, we should now see the result of web02 (because web01 is off)
There should be the Linux/Debian default web page
