Fikker——自建CDN加速

Fikker 是一款面向 CDN/站长 的专业级网站缓存(Webcache)和反向代$理服务器软件(Reversed Proxy Server)。

说明

a. 利用 Fikker 软件能够快速搭建一套完全自主管理的 CDN 系统。
b. 全部 Fikker 软件都可以在官方网站【下载】得到,全部为绿色安装包,请严格按照安装说明去做。

第一步:先安装 Fikker 缓存(推荐Linux系统!)    

将 Fikker 缓存安装在节点服务器上,用于缓存加速/反向代理等。:必需安装项。<截图效果>

1、一键安装脚本,直接拷贝所有脚本到Linux终端执行即可!      

CentOS 6.x/7.x 64 位版本为例,以 root 根用户登录,下面的脚本包含功能:
a、默认会关闭 iptables/nginx/httpd 服务,避免与 Fikker 的 80/443/6780 端口冲突。
b、默认会下载并解压 Fikker 安装包,默认安装在 /root 目录下面,最后注册成系统服务,并立即启动起来。

FikkerInstallDir="/root" # default installation directory FikkerNewVersion="fikkerd-3.7.8-linux-x86-64" # package name service iptables stop 2> /dev/null ; chkconfig iptables off 2> /dev/null ; service httpd stop 2> /dev/null ; service nginx stop 2> /dev/null ; chkconfig httpd off 2> /dev/null ; chkconfig nginx off 2> /dev/null ; systemctl stop firewalld.service 2> /dev/null ; systemctl disable firewalld.service 2> /dev/null ; systemctl stop httpd.service 2> /dev/null ; systemctl stop nginx.service 2> /dev/null ; systemctl disable httpd.service 2> /dev/null ; systemctl disable nginx.service 2> /dev/null ; yum -y install wget ; cd $FikkerInstallDir ; wget -c --no-check-certificate https://www.fikker.com/dl/$FikkerNewVersion.tar.gz && tar zxf $FikkerNewVersion.tar.gz && rm -rf $FikkerNewVersion.tar.gz && cd $FikkerNewVersion && ./fikkerd.sh install && ./fikkerd.sh start && cd $FikkerInstallDir && sleep 5 && echo 'finished!' ...

1、型号分类:Intel一共四类:酷睿三/四代,六代,七代、八代九代,AMD有三类:锐龙以前的型号、锐龙一代和二代。其中R3-2200G和R5-2400G严格来说属于锐龙一代,但采用了一些二代的特性,AMD对其也命名为2XXXG,因此图中仍然将其划分到第二代,这是一种花繁为简的做法,很多时候,我们需要牺牲一定的严谨性来换取简单。 ...
