操作系统： CentOS 6（x86_64）
我已经安装并configuration了清漆，但现在无法启动。
# service varnish restart Stopping Varnish Cache: [FAILED] Starting Varnish Cache: [FAILED] 我将这个错误缩小到/etc/varnish/default.vcl的另一个VCL文件。
我包括VCL像这样：
include "/etc/varnish/domains/playwithbits.vcl";
如果我清空playwithbits.vcl的内容，然后清漆能够开始，但只要我添加内容失败。
我的playwithbits.vcl的内容是：
backend playwithbits { .host = "localhost"; .port = "8080"; } acl purge { if (req.http.Host ~ "playwithbits.com") { "localhost"; } } sub vcl_recv { if (req.http.Host ~ "playwithbits.com") { set req.backend = playwithbits; if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } return(lookup); } if (req.url ~ "^/$") { unset req.http.cookie; } } } sub vcl_hit { if (req.http.Host ~ "playwithbits.com") { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } } sub vcl_miss { if (req.http.Host ~ "playwithbits.com") { if (req.request == "PURGE") { error 404 "Not in cache."; } if (!(req.url ~ "wp-(login|admin)")) { unset req.http.cookie; } if (req.url ~ "^/[^?]+.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(\?.|)$") { unset req.http.cookie; set req.url = regsub(req.url, "\?.$", ""); } if (req.url ~ "^/$") { unset req.http.cookie; } } } sub vcl_fetch { if (req.http.Host ~ "playwithbits.com") { if (req.url ~ "^/$") { unset beresp.http.set-cookie; } if (!(req.url ~ "wp-(login|admin)")) { unset beresp.http.set-cookie; } } }
这是# strace -e trace=file service varnish start

有谁知道这个问题是什么？
解：
问题在于下面的块：
acl purge { if (req.http.Host ~ "playwithbits.com") { "localhost"; } }
acl purge只能以string作为值，所以if是无效的。 replace为：
acl purge { "localhost"; }
它就像一个魅力。
用一个好的configuration（ default.vcl ？）开始清漆，然后在加载之前尝试在你的VCL上运行一个语法检查。 清漆v2.1（假设在3.x类似）：
$ varnishadm -T 127.0.0.1:6082 vcl.load error <path_to_your_vcl>
