9、这里还有一个Linux+Nginx+MySQL+PHP+Varnish一键安装包,自动安装完成:Varnish高性能开源HTTP加速器:Varnish Nginx和Varnish Apache搭建配置。 二、Varnish相关配置
1、设置好Varnish缓存规则。默认是/etc/varnish/default.vcl,大家可以下载这个Varnish WordPress配置文件覆盖原来的,地址:http://centos.googlecode.com/files/default.vcl。源码内容:
# This is a basic VCL configuration file for varnish. See the vcl(7) # man page for details on VCL syntax and semantics.
# Default backend definition. Set this to point to your content
# server.

}

# Below is a commented-out copy of the default VCL logic. If you
# redefine any of these subroutines, the built-in logic will be
# appended to your code.

# Only cache the following site

# X-Forwarded-For set. If you use X-Forwarded-For and want to
