Varnishキャッシュをクリアするにはどうすればよいですか？

ノードフローモジュールをPressflow 6 + Varnishにインストールしました。ノードキューのニスキャッシュをクリアするために、RulesおよびCacheアクションモジュールを使用してルールを開発しました。コンテンツを更新すると、ログインしたユーザーには反映されますが、匿名ユーザーには反映されません。

ワニスキャッシュをルールまたはカスタムコードでクリアする方法を教えていただけませんか？

Varnish HTTP Accelerator Integration モジュールをインストールして、設定ファイルに次の行を設定できます。

_/**
 * Varnishd Configuration
 *
 * This cache implementation can be used together with Varnish. You can't really use it to store or get any values, but you can use it to purge your caches.
 * This cache implementation should ONLY be used for cache_page and no other cache bin!
 */
if (class_exists('VarnishCache')) {
  // Add Varnish as the page cache handler.
  $conf['cache_backends'][] = 'sites/all/modules/contrib/varnish/varnish.cache.inc';
  // Drupal 7 does not cache pages when we invoke hooks during bootstrap. This needs to be disabled.
  $conf['page_cache_invoke_hooks'] = FALSE;
  $conf['cache_class_cache_page'] = 'VarnishCache';
}
_

次に、モジュールが有効な場合、標準のクリアキャッシュがVarnishのクリアキャッシュを呼び出す必要があります。

次の呼び出しを介してパージを直接呼び出すこともできます：varnish_purge_all_pages();

あるいは、カールを使用することもできます。

_curl -X PURGE -H "Host: domain.com" http://127.0.0.1/test.html
_

Cache Expiration モジュールは、ワニスを含むキャッシュからアイテムをクリアするように設計されています。

このモジュールは、リバースプロキシキャッシュなどのキャッシュからのURLを期限切れにするイベントを検出して処理するグリッドとして機能します。キャッシュ有効期限モジュールは、Boost有効期限コードの有効期限コードのスピンオフであり、他のモジュールがそれを使用できます。このモジュールは独立しており、Boostを使用しません。

Drupal Varnish Cacheを使用する8つのWebサイトを実行するには、 Purge module をインストールします。Purgeは、Drupal 8 adminキャッシュタグをサポートする必要があります。

Varnishでキャッシュタグをサポートするには、 Varnish Purgerモジュール をインストールします。 PurgeモジュールとVarnish Purgeモジュールをサポートするために必要なVarnish VCLコードの例については、こちら GitLabページ をご覧ください。

私はPHP ブログ投稿）からそれを行う方法の例 を見つけました：

$url = $_POST["url"];
$Host = $_POST["Host"];

$ip = "127.0.0.1";
$port = "80";

$timeout = 1;
$verbose = 1;

# inits
$sock = fsockopen ($ip,$port,$errno, $errstr,$timeout);
if (!$sock) { echo "connections failed $errno $errstr"; exit; }

if ( !($url || $Host) ) { echo "No params"; exit; }

stream_set_timeout($sock,$timeout);

$pcommand = "purge";
# Send command
$pcommand .= ".hash $url#$Host#";

put ($pcommand);
put ("quit");

fclose ($sock);

function readit() {
  global $sock,$verbose;
  if (!$verbose) { return; }
  while ($sockstr = fgets($sock,1024)) {
    $str .= "rcv: " . $sockstr . "<br>";
  }
  if ($verbose) { echo "$str\n"; }
}

function put($str) {
  global $sock,$verbose;
  fwrite ($sock, $str . "\r\n");
  if ($verbose) { echo "send: $str <br>\n"; }
  readit();
}
