## 实验环境（Centos7） ##

主机名            IP                版本
    varnish        192.168.14.210    4.0.5
    web1(nginx)    192.168.14.211    nginx/1.12.2
    client         192.168.14.212

## 一、varnish ##

官网地址：[http://varnish-cache.org/trac/wiki/VCLExamples][http_varnish-cache.org_trac_wiki_VCLExamples]

1、关闭防火墙和selinux

[root@varnish ~]# systemctl stop firewalld
    [root@varnish ~]# systemctl disable  firewalld
    [root@varnish ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

2、配置阿里epel源

[root@varnish ~]# vim /etc/yum.repos.d/epel.repo
    [epel]
    name=aliyun epel
    baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/
    gpgcheck=0

3、安装varnish

[root@varnish ~]# yum install -y varnish

修改前备份配置文件（可选）

[root@varnish ~]# cp /etc/varnish/varnish.params{,.bak}
    [root@varnish ~]# cp /etc/varnish/default.vcl{,.bak}

4、更改默认端口

更改前：
    [root@varnish ~]# cat /etc/varnish/varnish.params|grep VARNISH_LISTEN_PORT
    VARNISH_LISTEN_PORT=6081
    [root@varnish ~]# vim /etc/varnish/varnish.params
    
    更改后：
    [root@varnish ~]# cat /etc/varnish/varnish.params|grep VARNISH_LISTEN_PORT
    VARNISH_LISTEN_PORT=80

5、修改配置文件（简单配置只需修改两个地方）

backend default {
        .host = "192.168.14.211";
        .port = "80";
    }
    
    sub vcl_deliver {
        if (obj.hits>0) {
        set resp.http.X-Cache = "Hit via "+ server.ip;
        }else {
        set resp.http.X-Cache = "Miss via "+ server.ip;
        }
    }

6、启动varnish服务并开机启动

[root@varnish ~]# systemctl start   varnish
    [root@varnish ~]# systemctl enable  varnish

## 二、web ##

1、同上，关闭防火墙和selinux

2、同上，配置阿里epel源

3、安装nginx

[root@web1 ~]# yum install -y nginx

4、修改自定义主页

[root@web1 ~]# echo "nginx webserver1" > /usr/share/nginx/html/index.html 
    [root@web1 ~]# cat /usr/share/nginx/html/index.html 
    nginx webserver1

5、启动服务

[root@web1 ~]# systemctl start   nginx
    [root@web1 ~]# systemctl enable  nginx

三、客户端访问

1、centos访问

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 1][]

2、window访问

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

刷新浏览器，返回304状态码，并且是缓存服务器返回的数据

3、至此，varnish缓存服务器搭建成功
