ubuntu - Varnish digitalocean 配置指南 : Symbol not found: 'req.backend.healthy' (expected type BOOL): 后出错

Question

我关注了这个 https://www.digitalocean.com/community/tutorials/how-to-configure-varnish-for-drupal-with-apache-on-debian-and-ubuntu在运行 /etc/init.d/varnish restart 之后我收到了这个错误:

 * Stopping HTTP accelerator varnishd                                    [fail]
 * Starting HTTP accelerator varnishd                                    [fail]
Message from VCC-compiler:
Symbol not found: 'req.backend.healthy' (expected type BOOL):
('input' Line 44 Pos 9)
    if (req.backend.healthy)
--------###################-

Running VCC-compiler failed, exited with 2

VCL compilation failed

第 44 行是

if (req.backend.healthy)
{
    set req.grace = 60s;
}
else
{
    set req.grace = 30m;
}

我看到这个帖子 https://www.varnish-cache.org/lists/pipermail/varnish-misc/2014-May/023692.html这似乎认为它与版本有关。我在 Ubuntu 14.04 上运行 4.0.3 修订版 b8c4a34。

Answer 1

Varnish 4.* 与 Varnish 3.* 略有不同

如您所见，req.backend.healthy 不再存在 here .这样做的新方法是:

std.healthy(req.backend_hint)
