基于Linux VPS运行WordPress，很多站长几乎都会首选Centos系统，原因很简单开源、安全、稳健；
一般在VPS上远程下载文件的时候经常会用Wget命令，这是基于单线程下载模式；
那么在下载大文件或者网络环境不是很好想要下载速度快些的话就需要用到多线程工具，像电脑本地用IE下载速度不理想的时候，启动多线程下载工具速度很容易得到质的提升；
同样使用Centos系统下载文件时也可以用到多线程技术来提升速度，方案有不少这里分享Axel多线程下载方案；
一、首先确定一下Centos版本：
查询命令：cat /etc/redhat-release
二、下载axel插件的rpm包
Axel下载地址 http://pkgs.repoforge.org/axel/
比如我的系统是Centos 6.5 32位系统，那么就在下载地址列表中找到相对应得版本复制下载地址；
wget -c http://pkgs.repoforge.org/axel/axel-2.4-1.el6.rf.i686.rpm rpm -ivh axel-2.4-1.el6.rf.i686.rpm
附加上64位下载安装命令
wget -c http://pkgs.repoforge.org/axel/axel-2.4-1.el6.rf.x86_64.rpm rpm -ivh axel-2.4-1.el5.rf.x86_64.rpm
