Varnish Apache 集成到 503 后端提取在 MAC 中失败

Question

I tried to setup varnish on MAC for apache2(MAMP) using below steps

Step1. brew install varnish

Step2. Varnished installed then configured default.vcl

backend default {
    .host = "localhost";
    .port = "80";
    .first_byte_timeout = 600s;
    .probe = {
        .url = "/pub/health_check.php";
        .timeout = 2s;
        .interval = 5s;
        .window = 10;
        .threshold = 5;
   }
}

Step3. configured apache2 to run on port 8080

NameVirtualHost *:8080

<VirtualHost *:8080>

</virtualHost>

Step4. running 127.0.0.1 or localhost give below error

Error 503 Backend fetch failed
Backend fetch failed

I addressed a similar issue here: https://magento.stackexchange.com/questions/363095/magento2-4-5-varnish-alway-so-503-backend-fetch-fail/

It describes the following aspects:

• Changing the health check URL to /healt_check.php for recent versions of Magento
• Check the current backend health
• Debugging the output of the health check
• Considering that the health check might timeout after 2 seconds
