LVS Dr Mode disables ARP broadcast response settings for real backend servers

When deploying the LVS-DR mode, we need to disable ARP broadcast response to the VIP set for the backend RealServer, the backend RealServer may be Linux or Windows

(1) how to configure VIP for backend servers when RealServer is a Linux System

Real Server Configuration

IP configuration

1) IP Address: 10.0.0.11/16

GW: 10.0.0.139

 

VIP: 172.16.10.100

# Ifconfig lo: 0 172.16.10.100/32 broadcast 172.16.10.100 set the broadcast address to yourself.

 

Disable receiving broadcast response Configuration

# Vim/etc/sysctl. conf

Net. ipv4.conf. Lo. arp_ignore = 1

Net. ipv4.conf. Lo. arp_announce = 2

Net. ipv4.conf. All. arp_ignore = 1

Net. ipv4.conf. All. arp_announce = 2

# Sysctl-P

Or

# Yum install arptables_jf

# Arptables-A in-D 172.16.10.100-J Drop

 

Add route

# Route add-host 172.16.10.100 Dev lo: 0

(2) how to add a virtual IP address (VIP) of a Windows Server:

1. Disable or disable built-in Firewall

2. New loopback Nic

Method: start -- run -- hdwwiz

Or Win (the key between CTRL and ALT) + r key -- hdwwiz press Enter.

3. Configure the IP address of the loop IP address as the VIP address, mask 255.255.255.255

4. Modify Nic Information

Modify it in the command line, start -- run -- cmd
Netsh interface IPv4 set interface "Local Connection" weakhostreceive = Enabled
Netsh interface IPv4 set interface "Local Connection" weakhostsend = Enabled
Netsh interface IPv4 set interface "local connection 2" weakhostreceive = Enabled
Netsh interface IPv4 set interface "local connection 2" weakhostsend = Enabled
