清漆default.vcl

Question

我刚刚在我的开发服务器上安装了清漆，它正在运行，没有改变任何配置。所以现在它只要求Apache提供响应并将其传回。

嗯，我是个新手，我正在尝试缓存javascript、css和图像来测试清漆。我的问题是，如果我写返回(查找)；在vcl_recv中给我错误的服务清漆重新启动！！

vcl 4.0;

# Default backend definition. Set this to point to your content server.
backend default {
  .host = "127.0.0.1";
  .port = "80";
}

sub vcl_recv {
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
#hash_data(req.url);
#if (req.http.host) {
#    hash_data(req.http.host);
#} else {
#    hash_data(server.ip);
#}
return (lookup);
}

sub vcl_backend_response {
# Happens after we have read the response headers from the backend.
#
# Here you clean the response headers, removing silly Set-Cookie headers
# and other mistakes your backend does.

 }

sub vcl_deliver {
# Happens when we have all the pieces we need, and are about to send the
# response to the client.
#
# You can do accounting or modifying the final object here.
}

default.vcl中的此配置在重新启动时给出了下一个错误：

Job for varnish.service failed. See 'systemctl status varnish.service' and 'journalctl -xn' for details.

救救我！！

Answer 1

你可以这样做：

sub vcl_recv {
  if (req.url ~ "(?i)\.(jpeg|jpg|png|gif|ico|js|css)$") {
      unset req.http.Cookie;
      return (hash);
  } else {
      return (pass);
  }
}

Answer 2

问题是在default.vcl中端口是80。端口必须是web服务器正在监听的端口，例如8080。必须在8080中配置web服务器。在Debian中，您的/etc/systemd/system/varnish.service文件的端口必须更改为80。

ExecStart=/usr/sbin/varnishd -j unix，user=vcache -F -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/ -s malloc，512 m

然后，使用您的浏览器，您正在连接到80清漆和清漆询问web服务器从8080页和文件(缓存后第一次命中)。

如果文件不存在，请运行：

​

cp /lib/systemd/system/varnish.service /etc/systemd/system/ systemctl守护进程-重新加载&& systemctl状态清漆

并开始使用该文件，然后可以在/etc/varnish/default.vcl中输入代码。
