varnish安装与测试
部分内容转自：http://hi.baidu.com/supermfc/blog/item/21e74638f1f576feb311c71b.html
1、Pcre的安装 （PERL兼容正则表达式库）

wget http://cdnetworks-kr-1.dl.sourceforge.net/project/pcre/pcre/8.02/pcre-8.02.tar.bz2tar zxvf pcre-8.02.tar.gzcd pcre-8.02./configure --libdir=/usr/libmake && make install

如果没有安装Pcre，configure varnish2.0以上版本时候，会提示找不到pcre库

2、varnish 安装

wget http://cdnetworks-kr-2.dl.sourceforge.net/project/varnish/varnish/2.1.3/varnish-2.1.3.tar.gztar zxvf varnish-2.1.1cd varnish-2.1.1./configure --prefix=/usr/local/varnishmake && make install

3、varnish启动

   usage: varnishd [options]    -a address:port              # HTTP listen address and port    -b address:port              # backend address and port                                 #    -b <hostname_or_IP>                                 #    -b '<hostname_or_IP>:<port_or_service>'    -C                           # print VCL code compiled to C language    -d                           # debug    -f file                      # VCL script    -F                           # Run in foreground    -h kind[,hashoptions]        # Hash specification                                 #   -h simple_list                                 #   -h classic  [default]                                 #   -h classic,<buckets>    -i identity                  # Identity of varnish instance    -l bytesize                  # Size of shared memory log    -M address:port              # CLI-master to connect to.    -n dir                       # varnishd working directory    -P file                      # PID file    -p param=value               # set parameter    -s kind[,storageoptions]     # Backend storage specification                                 #   -s malloc                                 #   -s file  [default: use /tmp]                                 #   -s file,<dir_or_file>                                 #   -s file,<dir_or_file>,<size>                                 #   -s file,<dir_or_file>,<size>,<granularity>    -t                           # Default TTL    -S secret-file               # Secret file for CLI authentication    -T address:port              # Telnet listen address and port    -V                           # version    -w int[,int[,int]]           # Number of worker threads                                 #   -w <fixed_count>                                 #   -w min,max                                 #   -w min,max,timeout [default: -w2,500,300]    -u user                      # Priviledge separation user id

    

sbin/varnishd -a :8080 -n logs -f etc/varnish/default.vcl -T localhost:6082 -p thread_pools 8 -p first_byte_timeout 20 -p between_bytes_timeout 10m -s malloc,100m

4、varnish配置
  

   backend test {  .host = "102.21011.81.309";  .port = "8080";  .probe = {                .url = "/index.jsp";                .interval = 5s;                .timeout = 8 s;                .window = 5;                .threshold = 3;  }}director baz1 round-robin{          {                .backend = test;        }}sub vcl_recv {    set req.backend = baz1;    /* add x-forwarded-for */    if (req.http.x-forwarded-for) {        set req.http.X-Forwarded-For =            req.http.X-Forwarded-For ", " client.ip;    } else {        set req.http.X-Forwarded-For = client.ip;    }    /* ignore invalid request */    if (req.request != "GET" &&      req.request != "HEAD" &&      req.request != "PUT" &&      req.request != "POST" &&      req.request != "TRACE" &&      req.request != "OPTIONS" &&      req.request != "DELETE") {        /* Non-RFC2616 or CONNECT which is weird. */        return (pipe);    }    if (req.request != "GET" && req.request != "HEAD") {        /* We only deal with GET and HEAD by default */        return (pass);    }    if (req.http.Authorization || req.http.Cookie) {        /* Not cacheable by default */        return (pass);    }    /* // need cache turn on return (lookup);*/    return (pass);}sub vcl_pipe {    set req.http.connection = "close";    return (pipe);}sub vcl_deliver {    set resp.http.Server = "是";    return (deliver);}

5、用apache ab进行测试
    ab -n100000 -c1000 http://192.168.1.128:8080/index.jsp
