如果我使用vcl 5.1，

Varnish 5无法启动;或者vcl 5.0;在我的default.vcl

Varnish5文档说：

从Varnish 4.0开始，每个VCL文件必须首先使用＆＃34; vcl X.Y;＆＃34;声明其版本。文件顶部的标记。

但我使用的是Varnish 5.1

我试过vcl 5.0;或vcl 5.1;在我的default.vcl中，但它没有工作。

在VERSIONING下的手册页vcl（7）中解释了这一点（来自Debian 9上的Varnish 5 .0.0安装）：

   Multiple versions of the VCL syntax can coexist  within  certain
   constraints.

   The  VCL  syntax version at the start of VCL file specified with
   ''-f'' sets the hard limit that cannot be exceeded anywhere, and
   it selects the appropriate version of the builtin VCL.

   That  means  that  you  can  never  include "vcl 9.1;" from "vcl
   8.7;", but the opposite may be possible, to the extent the  com‐
   piler supports it.

   Files pulled in via include do not need to have a "vcl X.Y;" but
   it may be a good idea to do it anyway, to not have surprises  in
   the  future.   The  syntax  version set in an included file only
   applies to that file and any files it includes  -  unless  these
   set their own VCL syntax version.

   The  version of Varnish this file belongs to supports **syntax 4.0**
   only.
