一、安装varnish
# tar zxvf varnish-2.1.3.tar.gz
#cd varnish-2.1.3
#/configure –prefix=/opt/varnish
# make && make install
二、配置实例
# vi /opt/varnish/etc/varnish/test.vcl

启动varnish：
#ulimit -SHn 51200
#useradd -s /sbin/nologin www
## /opt/varnish/sbin/varnishd -u www -g www -f /opt/varnish/etc/varnish/test.vcl -a 192.168.2.4:80 -s file,/data/varnish_cache/varnish_cache.data,1G -w 1024,5100,10 -t 3600 -T 192.168.2.4:3500
参数: -u 以什么用运行
-g 以什么组运行
-f varnish配置文件
-a 绑定IP和端口
-s varnish缓存文件位置与大小
-w 最小，最大线程和超时时间
-T varnish管理端口，主要用来清除缓存
-s file,/data/varnish_cache/varnish_cache.data,1G 缓存目录，这个32位系统不能超过2G的，建议使用64位系统，还有想要更快的速度，把这个目录改成内存缓存会更快,内存越大越好
停止varnish：
#pkill varnishd
