设置haproxy和varnish时出错

我一直在关注如何使用haproxy安装varnish haproxy博客的教程。 （ 链接 ）这部分的haproxyconfiguration设置有问题：

frontend ft_web_static bind 10.0.1.3:80 monitor-uri /haproxycheck # Tells Varnish to stop asking for static content when servers are dead # Varnish would deliver staled content monitor fail if nbsrv(bk_appsrv_static) eq 0 default_backend bk_appsrv_static 

当我重新启动haproxy，它给了我这个错误：

 [root@ch]# service haproxy restart [ALERT] 348/004936 (28582) : parsing [/etc/haproxy/haproxy.cfg:282] : error detected while parsing a 'monitor fail' condition : no such ACL : 'nbsrv(apache2_static)'. 

我想有一些错误的nbsrv(bk_appsrv_static) eq 0 。 有人在文章后的评论部分也提出了这个问题，但没有人有解决办法。 任何人都可以找出在设置中是否有错字或错误？

这是完整的configuration：

• 在本地服务http内容文件，而不是外部服务器
• 清漆恶魔错误：找不到libvarnish.so.1
• 如何快速提供静态文件？
• Apache性能分析
• 是同时使用Nginx和Varnish redudant吗？
