centOS上不支持rar解压，需要额外安装软件，收费版是unrar，免费版是unar

unar在centOS上安装需要源码编译，下面是安装方法：

1.安装依赖

yum install gnustep-base-devel

yum install zlib-devel

yum install bzip2-devel

yum install openssl-devel

yum install libicu-devel

2.安装编译依赖

yum install gcc-objc.x86_64

yun install gcc-objc++.x86_64

yum install mingw64-gcc-objc.x86_64

yum install mingw64-gcc-objc++.x86_64

3.下载并编译源码

https://theunarchiver.com/downloads/TheUnarchiverSource.zip

cd XADMaster

make -f Makefile.linux

4.安装

编译成功后XADMaster下出现unar可执行文件

复制到/usr/bin,/usr/local/bin即可
