Question

我想知道是否有人可以告诉我我做错了什么。

我在前端服务器上安装了Varnish，这很有效。我可以将几个公共网站的IP地址（包括CNN）放入配置中，它们由Varnish缓存。

当我将我的一个网站IP地址'放入Varnish时，我从Litespeed服务器收到404错误 - 这表明它正在连接到服务器，但显然没有选择正确的网站来显示Varnish。我在Litespeed服务器上有几个域，每个域都有自己的IP地址。直接URL也是如此。

我猜这是Litespeed配置的一个问题 - 但是任何帮助都会受到赞赏。

作为参考，我正在使用PageCache的VCL配置文件，它是Varnish的Magento模块。

## Alternative 2, Configuration with VCL
#
# Listen on port 6080, administration on localhost:6082, and forward to
# one content server selected by the vcl file, based on the request.  Use a 1GB
# fixed-size cache file.

DAEMON_OPTS="-a :80 \
         -T localhost:6082 \
         -f /etc/varnish/default.vcl \
         -S /etc/varnish/secret \
         -s malloc,256m"

Answer 1

您的Varnish服务器绑定到哪个端口？您对Litespeed使用什么端口？

如果您可以在此处发布配置文件以便为您提供进一步的建议，那将非常有用。

Answer 2

这就是我需要的！ Configure multiple sites with Varnish

我需要将虚拟主机名放入配置文件中。按照本指南进行操作吧！
