正常rar是windows下的压缩文件，linux是不支持的。但是可以通过安装rarlinux来使用rar命令解压rar文件。
首先下载rarlinux
[root@localhost ~]# wget http://rarsoft.com/rar/rarlinux-4.0.1.tar.gz --2015-07-17 22:59:37-- http://rarsoft.com/rar/rarlinux-4.0.1.tar.gz Resolving rarsoft.com... 5.135.104.98 Connecting to rarsoft.com|5.135.104.98|:80... connected.

按照上面的步骤，下载好rarlinux安装包、解压缩、进入文件夹执行make，就可以使用命令了。
