On each of the load balancer servers, modify the “net.ipv4.ip_nonlocal_bind” to 1 in the kernel file
/etc/sysctl.conf. This allows OpenResty to bind to a shared IP address which is 10.246.150.151 in this example. With an editor, such as “vi”, add the line shown in Figure 56.
net.ipv4.ip_nonlocal_bind=1
Run the “sysctl –p” command to have this setting take effect without the need to reboot as shown in Figure 57.
sysctl -p
