Linux-Varnish缓存

实验环境:

centos7.3

安装:

Jemalloc和varnish-libs先安装哪个都可以,varnish依赖varnish-libs,所以放在最后安装

[root@xuegod63 ~]# rpm -ivh varnish-libs-4.0.5-1.el7.x86_64.rpm    

[root@xuegod63 ~]# rpm -ivh jemalloc-3.6.0-1.el7.x86_64.rpm          #内存控制工具

[root@xuegod63 ~]# rpm -ivh varnish-3.0.6-1.el6.x86_64.rpm

vcl置文件:

[root@xuegod63 ~]# ls /etc/varnish/default.vcl

varnish主配置文件:

[root@xuegod63 ~]# vim /etc/varnish/varnish.params

启动varnish服务:

[root@xuegod63 ~]# systemctl start varnish

 

 

缓存多个网站:

       代理服务器:      192.168.1.201          www.vampire.com bbs.vampire.com

         Web1 :          192.168.1.202

         Web2:          192.168.1.203

配置varnish服务端口:

[root@vampire63 ~]# vim /etc/varnish/varnish.params

改:

66 VARNISH_LISTEN_PORT=6081

为:

VARNISH_LISTEN_PORT=80

修改varnish服务器的配置文件:

[root@localhost ~]# vim /etc/varnish/default.vcl

改:

backend web1 {

  .host = "127.0.0.1";

  .port = "8080";

}

为:

backend web1 {

  .host = "192.168.1.202";

  .port = "80";

}

backend web2 {

  .host = "192.168.1.203";

  .port = "80";

}

注:若有多个网站,只需添加backend,指定对应的名称,以便进行匹配

实现以下功能:

当访问www.vampire.com域名时从web1上取数据,

访问bbs.vampire.com域名时到web2取数据

[root@localhost ~]# vim /etc/varnish/default.vcl  #在sub vcl_deliver 处定义以下内容:

sub vcl_recv {

if (req.http.host ~ "(?i)^(www.)?vampire.com$") {

        set req.http.host = "www.vampire.com";

        set req.backend_hint = web1;

      } elsif (req.http.host ~ "(?i)^bbs.vampire.com$") {

            set req.backend_hint = web2;

    return(hash);

  }

}

注:此处需要注意需要在varnish代理服务器上面修改hosts文件,或者在DNS服务器上面天添加解析

此处为修改本地hosts文件:

[root@localhost ~]#vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.1.201  www.vampire.com

192.168.1.201  bbs.vampire.com

 

重新加载varnish配置文件:

[root@localhost ~]# systemctl reload varnish
