在内网的vps上安装Varnish的最新版3.0来用做测试
Varnish有centos下的rpm和ubuntu下的deb二进制包下载，但我选择的是源码编译安装
先下载 wget
tar -xzvf varnish-3.0.0.tar.gz
yum install gcc
yum install gcc-c++ libstdc++-devel
yum install -y httpd-devel pcre perl pcre-devel zlib zlib-devel GeoIP GeoIP-devel
Varnish需要pcre支持，如果服务器没有安装pcre-devel会提示需要指定prce目录。
Centos服务器上使用yum install pcre-devel安装
解压varnish进行编译安装
cd varnish-3.0.0
./autogen.sh
./configure --prefix=/usr/local/varnish PKG_CONFIG_PATH=/usr/lib/pkgconfig
make
make install
安装成功后,安装的目录是
cd /usr/local/varnish/sbin
./varnishd -V
查看版本，看是否安装成功
测试varnish
先编辑配置文件
vi /usr/local/varnish/etc/varnish/default.vcl
# 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.

/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
(开启varnish的端口号)
戴图显示，nginx 为177上运行的web服务器，出现了varnish字样，表示缓存架设成功，已正常工作了。
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： 引用
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 &
vi /etc/sysctl.conf
在末尾增加以下内容： 引用
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
配置启动脚本：
mkdir /cache/varnish/V -p
vi /usr/local/varnish/sbin/start.sh
#!/bin/sh
#file:start.shdate -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=512chmod 777 start.sh
运行：
/usr/local/varnish/sbin/start.sh
