wordpress – Varnish nginx ssl woocommerce – wc-ajax表现不佳

所以我有点奇怪.我有一台运行@R_403_196@,Varnish,PHP-fpm和wordpress / woocommerce的debian 9机器.该网站基本上有效,但我有一些奇怪的问题,添加到购物车.

测试环境为https://awstesting.amr.com.au

具体来说,在主页上有“添加到购物车”按钮.在页面加载时,您可以添加2个不同的产品,但是如果您尝试使用第3个产品,它将使用502的ajax调用失败.

这是点击添加到购物车时的常规标题部分：

Request URL: https://awstesting.amr.com.au/?wc-ajax=add_to_cart
Request Method: POST
Status Code: 502 
Remote Address: 13.236.17.191:443
Referrer Policy: no-referrer-when-downgrade

我现在将添加我的Varnish配置:(我正在使用Varnish 5.2)

vcl 4.0;

        .host = "127.0.0.1";
        .port = "8080";

                return (deliver);
        }
}

sub vcl_purge {
        set req.method = "GET";
        set req.http.X-Purger = "Purged";
        return (restart);
}



sub vcl_backend_response {

    if (beresp.status >= 300) {
        if (beresp.status == 500) {
            return (retry);
        }
        set beresp.uncacheable = true;
        set beresp.ttl = 2s;
    }
    else
{
        set beresp.ttl = 24h;
        set beresp.grace = 1h;
    }

    if (bereq.url !~ "wp-admin|wp-login|product|cart|checkout|my-account|/?remove_item=|/?wc-ajax=") {
        unset beresp.http.set-cookie;

}

sub vcl_deliver {

        }
}

sub vcl_pipe {
        return (pipe);
}

sub vcl_pass {
        return (fetch);
}

}

此配置具有后端http服务器和将请求传递给varnish的前端代理https.

香港专业教育学院尝试了一些不同的清漆配置,但无济于事.所以我有点迷失了什么.我可以清楚地看到服务器正在返回502,我怀疑这意味着http @R_403_196@服务器无法确定将产品添加到购物车的意图.

非常感激任何的帮助.

提前致谢,

所以罪魁祸首竟然是清漆.我绕过了清漆,网站表现得如预期的那样.我假设清漆对标题大小有更严格的规则,因此连接断开.

如果我最终解决了这个问题,我将更新这篇文章.

最佳答案

正如这些网站解释
https://www.scalescale.com/tips/nginx/502-bad-gateway-error-using-nginx/

@R_403_196@ with PHP-FPM: same as Apache example,let’s imagine your PHP daemon stop working,or get’s overloaded by requests,it will not work
properly and the all the PHP requests from @R_403_196@ would not be served,
so,a 502 Bad Gateway error will appear. How to fix it? Restart
PHP-fpm daemon and check the logs.

理解这个评论和你的消失配置我可以想象一个场景在哪里
Vanish Proxy将Ajax请求传递给
@R_403_196@ Web服务器本身想要传递给它
PHP,但最终仍然忙于处理wordpress之前的请求.
因此,@R_403_196@ Web服务器将报告错误 502 错误网关

我建议你禁用Varnish Cache并尝试在没有它的情况下操作wordpress 站点,看看错误是wordpress应用程序还是Varnish Cache的问题.
还会在日志中显示请求的处理时间.

我还观察到@R_403_196@日志与Varnish Logs与Timestamps不匹配.

看到@R_403_196@活动日志以查看哪些请求实际转发以及它们在Web服务器中具有哪些响应将是非常有趣的.
