源码包编译安装:

cd /usr/local/src && wgethttp://nchc.dl.sourceforge.net/sourceforge/varnish/varnish-1.1.1.tar.gz
tar zxvf /usr/local/src/varnish-1.1.1.tar.gz
cd /usr/local/src/varnish-1.1.1
./autogen.sh
./configure --enable-debugging-symbols --enable-developer-warnings --enable-dependency-tracking

注:如果你gcc版本是4.2.0或更高版本可以加上--enable-extra-warnings编译参数在出错时得到附加警告信息
我这里是用源码包安装如果你是redhat或centos可以用rpm包来安装

2. 建立cache目录:

mkdir -p /cache/varnish/V  && chown -R nobody:nobody /cache

3.编写启动文件:

cd /usr/local/varnish/sbin
vi start.sh

内容如下:
#!/bin/sh
# file: start.sh
date -u
/usr/local/varnish/sbin/varnishd \
-a 10.0.0.129:80 \
-s file,/cache/varnish/V,1024m \
-f /usr/local/varnish/sbin/vg.vcl.default \
-p thread_pool_max=1500 \
-p thread_pools=5 \
-p listen_depth=512 \
-p client_http11=on \

注:-a 是指定后端服务器ip或hostname就象squid做revese proxy时originserver.

不过这个也可以在vcl里面写
-f 是指定所用vcl文件
-s 指定cache目录存储类型文件位置和大小
-p 是指定varnish启动些启动参数可以根据自己机器配置来优化varnish性能
其他参数已经参数具体含义可以用varnishd --help 来查看

4.编写vcl:

我vcl如下:

backend default {
         backend.host = "127.0.0.1";
         backend.port = "http";
}

#我用是台机器做测试使用backend用是127.0.0.1:80.如果varnish机器和后台机器分开
写上对应机器ip或hostname就可以了

sub vcl_recv {

         (req.request != "GET" && req.request != "HEAD") {
                pipe;
        }

         (req.http.Expect) {
                pipe;
        }

         (req.http.Authenticate || req.http.Cookie) {
                pass;
        }

         (req.request "GET" && req.url ~ "\.(g|jpg|swf|css|js)$") {
                lookup;
        }
                lookup;
        }

sub vcl_pipe {
        pipe;
        }

sub vcl_pass {
        pass;
        }

sub vcl_hash {
             hash;
         }

sub vcl_hit {
         (!obj.cacheable) {
                pass;
        }
                deliver;
        }

sub vcl_timeout {
        discard;
}

sub vcl_discard {
        discard;
}

如果是多个站点在区别originserver时可以使用下面配置:

backend www {
       backend.host = "www.abc.com";
       backend.port = "80";
         }

backend images {
       backend.host = "images.abc.com";
       backend.port = "80";
         }

sub vcl_recv {
       (req.http.host ~ "^(www.)?abc.com$") {
             req.http.host = "www.abc.com";
             req.backend = www;
      } els (req.http.host ~ "^images.abc.com$") {
             req.backend = images;
      } {
            error 404 "Unknown virtual host";
}

5.启动varnish:

/usr/local/varnish/sbin/start.sh

Mon Sep  3 03:13:19 UTC 2007
