先下载 wget http://repo.varnish-cache.org/source/varnish-3.0.0.tar.gz
tar -xzvf varnish-3.0.0.tar.gz

/usr/local/varnish/sbin/varnishd -f /usr/local/varnish/etc/varnish/default.vcl -s malloc,1024m -T 127.0.0.1:200 -a 0.0.0.0:80
现在可以打开varnish了
http://192.168.0.10/ (开启varnish的端口号)
启动varnishncsa用来将Varnish访问日志写入日志文件：
/usr/local/varnish/bin/varnishncsa -n /var/vcache -w /var/logs/varnish.log &
配置开机自动启动Varnish
vi /etc/rc.local
在末尾增加以下内容：
ulimit -SHn 51200
/usr/local/varnish/sbin/varnishd -n /var/vcache -f /usr/local/varnish/vcl.conf -a 0.0.0.0:80 -s file,/var/vcache/varnish_cache.data,1G -g www -u www -w 30000,51200,10 -T 127.0.0.1:3500 -p client_http11=on
/usr/local/varnish/bin/varnishncsa -n /var/vcache -w /var/logs/youvideo.log &
优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000
查看Varnish服务器连接数与命中率
/usr/local/varnish/bin/varnishstat
配置启动脚本：
mkdir /cache/varnish/V -p
vi /usr/local/varnish/sbin/start.sh
#!/bin/sh
#file:start.sh
date -u
/usr/local/varnish/sbin/varnishd -a 0.0.0.0:80 -s file,/cache/varnish/V,1024m -f /usr/local/varnish/etc/varnish/default.vcl -p thread_pool_max=1500 -p thread_pools=5 -p listen_depth=512
chmod 777 start.sh
运行：
/usr/local/varnish/sbin/start.sh
我来转转，博主新年快乐~
