Linux Haproxy for simple four-layer load balancing

HAProxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution.

Haproxy four-layer load Balancing Setup

Host Planning:

Server 192.168.1.148 provides haproxy services

Backstage Web1 192.168.1.150

Alternatively, you can use Killall haproxy to kill the process.

Test after everything is done

Open the other two web machines and launch the Apache service.

Test Load Balancing

The server address of the browser-side input haproxy is constantly refreshed, you can see the following results

Thus, the purpose of load balancing is achieved.

Close one of the web machines

Refresh the Status Display page to see
