varnish3安装及配置

1.varnish安装

下载varnish软件  （此处下载3.0.2版本）

 

#wget   http://repo.varnish-cache.org/source/varnish-3.0.2.tar.gz
#tar -xvf varnish-3.0.2.tar.gz
#cd varnish-3.0.2
#./configure --prefix=/usr/local/varnish
#make &&make install

至此安装完成。

注：如果你在编译的vasnish中的bin目录没有发现varnishstat, varnishtop, varnishhist这个三个程序的话，是因为编译前没有安装与操作系统位数对应的ncurses-devel。

安装ncurses-devel

yum install ncurses-devel.x86_64

 

然后再次编译varnish 即可。

 

2.varnish配置

#vim /usr/local/varnish/etc/varnish/vcl.conf 

以下为配置代码：(除backend 及vcl_recv外，其他地方无需更改，这里是更改其访问的主机名，及定义后端服务器地址，字数有限，其他代码这里就不解释了)

   

#backend vhost
backend  192.168.40.85 {
.host = "192.168.40.85";
.port = "80";
}
#acl
acl purge {
  "localhost";
  "127.0.0.1";
  "192.168.0.0"/24;
}
sub vcl_recv {
        if (req.http.Accept-Encoding) {
            if (req.url ~ "\.(jpg|png|gif|jpeg|flv)$" ) {
                remove req.http.Accept-Encoding;
                remove req.http.Cookie;
            } else if (req.http.Accept-Encoding ~ "gzip") {
                set req.http.Accept-Encoding = "gzip";
            } else if (req.http.Accept-Encoding ~ "deflate") {
                set req.http.Accept-Encoding = "deflate";
            } else {
                remove req.http.Accept-Encoding;
            }
        }
           if (req.http.host ~  "(.*)youdomain.com") {
                       set req.backend = 192.168.40.85;
                 }
            else {
                        error 404 "This website is maintaining or not exist！";
                }

                req.http.X-Forwarded-For + ", " + client.ip;
        } else {

    }
    return (hash);
}

sub vcl_hit {
   if (req.request == "PURGE") {
       set obj.ttl = 0s;

    return (deliver);
