centos安装配置varnish
如果再整合DNS,GeoIP,Nginx可就称得上私有的CDN服务了！

  1. [root@Centos ~]# yum install logrotate libgomp gcc cpp binutils kernel-headers glibc-headers glibc-devel -y #安装所需环境
  2. [root@Centos ~]# rpm --nosignature -i http://repo.varnish-cache.org/redhat/varnish-3.0/el5/noarch/varnish-release-3.0-1.noarch.rpm #安装varnish
