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.gz
cd pcre-8.02
./configure --libdir=/usr/lib
make && 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.gz
tar zxvf varnish-2.1.1
cd varnish-2.1.1
./configure --prefix=/usr/local/varnish
make && 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
