清漆清除配置导致启动错误

Question

我在 Varnish 中的清除配置有问题。我有一个如下配置的清除 URL，但在尝试启动服务时，我得到一个错误，如下所示。如果我注释掉这段配置，服务将毫无问题地启动。有人知道我哪里出错了吗？

干杯。

sub vcl_recv {
  #purge all
  if (req.request == "PURGE") {
    if (!client.ip ~ purge) {
      error 405 "Not allowed.";
    }
    if (req.url ~ "varnish/index/purgeall/key/#Fj1nzljh") {
      purge_hash( ".*" );
    }
  }

启动时的错误信息如下：

user@ubuntu:/var/www$ sudo service varnish start

Answer 1

在 3.0.x 中正确的做法是这样的：

acl our_lan {
    "localhost";
    "10.0.0.0"/8;
    "192.168.0.0"/16;
}

sub vcl_recv {
    # ...
    if (req.request == "PURGE") {
        if (! (client.ip ~ our_lan)) {
            error 405 "Not allowed.";
        }
        return (lookup);
    }
    # ...
}

sub vcl_hit {
    if (req.request == "PURGE") {
        purge;
        error 200 "Purged.";
    }
}

sub vcl_miss {
    if (req.request == "PURGE") {
        error 200 "OK: but URL not in cache.";
    }
}

YMMV.

Answer 2

purge_hash 似乎已在最新版本的 varnish http://www.varnish-cache.org/trac/changeset/e20226fa977bb3e05d49b4e497a0b9f64ca5f272 中被删除

好像要清除整个缓存，可以通过其他清除功能来实现
