Nginx-S should also be configured with the same Nginx proxy service configuration as Nginx-M.

Keepalived service configuration for Nginx-M and Nginx-S:

Profile template:

This monitoring script Nginx-S server also needs:

Script template:

#! / bin/bash

Counter=$ (ps-C nginx-- no-heading | wc-l)

If ["${counter}" = "0"]; then

Service nginx restart

Sleep 2

Counter=$ (ps-C nginx-- no-heading | wc-l)

If ["${counter}" = "0"]; then

Service keepalived stop

Fi

Only Apache service needs to be set up on the WEB server, and no other network settings are needed.

Turn on the keepalived and Nginx services on the Nginx-M and Nginx-S servers, then execute the monitoring script under / opt/, and then stop any of the Nginx proxy servers to verify whether one of the Nginx proxy servers is down. The other continues to work.
