The following gives you a comprehensive introduction to the use of IIS+haproxy+keepalived+nginx in the production environment, hoping to give you some help in practical application. Load balancing involves more things, there are not many theories, and there are many books on the Internet. Today, we will use the accumulated experience in the industry to do an answer.

IIS+haproxy+keepalived+nginx is used in the architecture of the actual production environment, which needs to be studied comprehensively.

Toss about haproxy for a long time, in general, there are still a lot of details to sort out.

Environment:

Front end: haproxy IP:192.168.71.128

Backend WEB:

Server01:apache 192.168.71.138 (Linux)

Http://192.168.71.138

Server02:apache 192.168.71.135 (windows)

Http://192.168.71.135

Test purpose:

The front-end haproxy provides load balancing and disaster recovery redundancy for the two back-end Web CVMs.
