运行 VCC 编译器失败

每当我运行命令 sudo service varnish restart 时，它都会显示以下消息

* Stopping HTTP accelerator varnishd                                    [fail]
* Starting HTTP accelerator varnishd                                    [fail]

您的配置文件中有语法错误。您需要修复它。

Expected '.' got 'sub'
program line 98), at
('input' Line 11 Pos 1)

意味着错误发生在配置文件的第 11 行（使用显示行号的编辑器会非常有用）：

  1.  # This is a basic VCL configuration file for varnish.  See the vcl(7)
  2.  # man page for details on VCL syntax and semantics.
  3.  #
  4.  # Default backend definition.  Set this to point to your content
  5.  # server.
  6.  #
  7.  backend default {
  8.      .host = "127.0.0.1";
  9.      .port = "8080";
 10.  # Drop any cookies sent to Wordpress.
 11.  sub vcl_recv {
 12.          if (!(req.url ~ "wp-(login|admin)")) {
 13.                  unset req.http.cookie;
 14.         }

似乎11. sub vcl_recv {有人在第 3 行试图在后端规范中定义 VCL 子程序，这不是有效的语法……

答案2

关闭后端：

backend default {
    .host = "127.0.0.1";
    .port = "8080";
**}**
