Magento varnish缓存服务器：错误503服务不可用

我在一个AWS EC2实例上安装了varnish（varnish-3.0.5修订版1a89b1f）和NexAccess松节油（0.6.1），并将varnish listen更改为80，httpd listen 8080

前端错误：

Error 503 Service Unavailable
Service Unavailable
Guru Meditation:
XID: 2017409829
Varnish cache server

8080可以访问后端magento

“netstat-ntl”输出为：

我尝试通过以下技巧来修复它：

• 调整第一个字节\u超时和两个字节之间的\u超时
• “chkconfig--list varnish”以确保varnish状态处于打开状态
• “服务iptables状态”已关闭
• 设置一个更大的连接超时

但没有任何帮助

我用varnishlog来查找

FetchError   - http first read error: -1 11 (Resource temporarily unavailable)
