2、解压

[root@VM-3-11-centos local]# tar -xzvf ./rarlinux-x64-6.0.2.tar.gz 
rar/
rar/unrar
rar/acknow.txt
rar/whatsnew.txt
rar/order.htm
rar/readme.txt
rar/rar.txt
rar/makefile
rar/default.sfx
rar/rar
rar/rarfiles.lst

3、cd到解压目录，再make命令编译

[root@VM-3-11-centos local]# cd ./rar
[root@VM-3-11-centos rar]# ls
acknow.txt  default.sfx  license.txt  makefile  order.htm  rar  rarfiles.lst  rar.txt  readme.txt  unrar  whatsnew.txt

4、make命令编译

[root@VM-3-11-centos rar]# make
mkdir -p /usr/local/bin
mkdir -p /usr/local/lib
cp rar unrar /usr/local/bin
cp rarfiles.lst /etc
cp default.sfx /usr/local/lib

5、尝试打rar命令，出现以下信息表示安装成功
