1.说明

要安装一个.rar格式的应用，上传 Linux 系统后发现没有解压工具，上网搜索后开始一波三折的旅程。

2.安装

2.1 跳坑

# 有小伙伴分享安装方法
yum install rar
# 安装后根本无法使用 unrar 命令

2.2 一波三折

WinRAR 官网下载 这里有各种操作系统不同语言的版本，下载注意【坑1️⃣】：

# 查询系统版本信息是 x86_64 
rpm -qi centos-release
Name        : centos-release
Version     : 7
Release     : 9.2009.1.el7.centos
Architecture: x86_64

查询系统版本信息是x86_64是64 bit 的 x86 指令集系统如果点击RAR 6.11 for Linux x86下载到的rarlinux-x32-611.tar安装包是32 bit的，安装后使用报错：

-bash: /usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

重新下载64 bit的安装包rarlinux-x64-611.tar：

# 解压 安装
tar -zxvf rarlinux-x32-611.tar
cd rar
make
make install

3.使用

【坑2️⃣】安装成功后用了小伙伴举例的解压命令：

# 怎知道这个是 without archived paths
unrar e xxx.rar
# 带路径的用 
unrar x xxx.rar

# 仅贴出两个参数
