Centos上安装部署varnish图片缓存服务器进行加速

centos安装配置varnish
如果再整合DNS,GeoIP,Nginx可就称得上私有的CDN服务了!

[root@Centos ~]# yum install logrotate libgomp gcc cpp binutils kernel-headers glibc-headers glibc-devel -y #安装所需环境
[root@Centos ~]# rpm --nosignature -i http://repo.varnish-cache.org/redhat/varnish-3.0/el5/noarch/varnish-release-3.0-1.noarch.rpm #安装varnish
[root@Centos ~]# yum install varnish -y #安装varnish
[root@Centos ~]# service varnish start
Starting Varnish Cache:                                    [  OK  ]
[root@Centos ~]# cp /etc/sysconfig/varnish /etc/sysconfig/varnish.default #备份varnish默认的配置文件
[root@Centos ~]# sed -i '/VARNISH_LISTEN_PORT=6081/s/6081/80/'  /etc/sysconfig/varnish #varnish默认端口为6081,改为80
[root@Centos ~]# cp /etc/varnish/default.vcl /etc/varnish/default.vcl.default #备份varnish默认的配置文件
[root@Centos ~]# vi /etc/varnish/default.vcl #修改backend的值
backend default {
  .host = "目标IP或域名";
  .port = "目标端口";
}
[root@Centos ~]# cp /etc/sysconfig/varnish /etc/sysconfig/varnish.default
[root@Centos ~]# vim /etc/sysconfig/varnish
VARNISH_STORAGE_SIZE=50% #缓存文件大小
[root@Centos ~]# more /etc/varnish/default.vcl #只缓存文本文件js等跟图片
backend default {
  .host = "baiqiuyi.com";
  .port = "80";
} 
sub vcl_recv {
    remove req.http.X-real-ip; 
    set req.http.X-real-ip = client.ip; 
    set req.http.X-Forwarded-For = client.ip;

}

}
