如何检查清漆是否被激活为Symfony？

Question

我想为Symfony和我的eZ平台CMS.I使用漆。我遵循本教程来设置我的Varnish：Started.html#exercise-install-varnish

因此，我有以下工作服务器：

• 清漆监听端口80
• 清漆在本地主机上使用后端:8080
• Apache侦听本地主机:8080

我还设置了我的eZ平台ezplatform.yml和ezplatform.conf，以禁用默认缓存并启用清漆(我猜)。

我在ezplatform.conf中添加了这两行，以跟踪文档https://doc.ez.no/display/TECHDOC/Using+Varnish：

SetEnv USE_HTTP_CACHE 0 
SetEnv TRUSTED_PROXIES "0.0.0.0"

我将0.0.0.0用于Varnish地址，因为netstat -nlpt为Varnish提取了以下地址：

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      11151/varnishd      
tcp        0      0 127.0.0.1:1234          0.0.0.0:*               LISTEN      11151/varnishd  

所以我想这是正确的价值。然后，我在ezplatform.yml中添加了以下行(查看上面的文档)：

ezpublish:
    http_cache:
        purge_type: http
    siteaccess:
        list: [site]
        groups:
            http_cache:
              purge_servers: 0.0.0.0:80

清漆和httpd重新启动良好。然后，我检查了本地网站是否使用了Varnish，检查了HTTP标头，得到了如下结果：

Via: "1.1 varnish-v4"
X-Varnish: "32808"

我想这是一个很好的进步。总之，在Symfony分析器中，我仍然有以下情报人员：

Cache Information
   Default Cache    default
   Available Drivers    Apc, BlackHole, FileSystem, Memcache, Redis, SQLite
   Total Requests   349
   Total Hits   349
Cache Service: default
   Drivers  FileSystem
   Calls    349
   Hits     349
   Doctrine Adapter     false
   Cache In-Memory  true

还能拿到这个是正常的吗？它不应该是类似默认缓存:清漆而不是默认吗？我如何检查我的清漆目前是否在我的网站上工作，而不是symfony默认缓存？

顺便说一下，这是我的vcl文件：

#
# This is an example VCL file for Varnish.
#
# It does not do anything by default, delegating control to the
# builtin VCL. The builtin VCL is called when there is no explicit
# return statement.
#
# See the VCL chapters in the Users Guide at https://www.varnish-cache.org/docs/
# and https://www.varnish-cache.org/trac/wiki/VCLExamples for more examples.

# Marker to tell the VCL compiler that this VCL has been adapted to the
# new 4.0 format.
vcl 4.0;
import directors;

# Default backend definition. Set this to point to your content server.
backend default {
    .host = "127.0.0.1";
    .port = "8080";
}

sub vcl_init {
    new backs = directors.hash();
    backs.add_backend(default, 1);
}

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.
    set req.http.X-cookie = req.http.cookie;
    if (!req.http.Cookie ~ "Logged-In") {
         unset req.http.Cookie;
    }
    if (req.url ~ "\.(png|gif|jpg|png|css|js|html)$") {
         unset req.http.Cookie;
    }
}

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.
}

即使没有完成，我也不知道Symfony默认缓存是如何工作的，因为我已经在配置文件中禁用了它。

谢谢你的帮助。

如果你看到这样的事情

Via: "1.1 varnish-v4"
X-Varnish: "32808"

你的漆起作用了。为什么禁用symfony缓存呢？你可以同时使用..。可能说得通也可能说不通。这在很大程度上取决于程序逻辑。

如果您想在开发过程中对您的清漆有更深入的了解，可以添加以下几行：

sub vcl_deliver {
  if (obj.hits > 0) { # Add debug header to see if it's a HIT/MISS
    set resp.http.X-Cache = "HIT";
  } else {
    set resp.http.X-Cache = "MISS";
  }
  # show how ofthe the object created a hit so far (reset on miss)
  set resp.http.X-Cache-Hits = obj.hits;
}
