2018-08-28 centos 处理 rar文件踩吭记

1. 解压命令：
   unrar e 半世界之旅-广州米壳.rar ./mike_creatives/

2. 下载安装包：
   wget http://www.rarsoft.com/rar/rarlinux-5.6.0.tar.gz

3. 安装：
   tar -xvf rarlinux-5.6.0.tar.gz
   cd rar
   make

4. 使用：
   a. unrar --help
   -bash: /usr/local/bin/unrar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

yum install glibc.i686 （解决lib库的32位和64位混乱问题）

b. unrar --help
unrar: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

uname -m&&uname -r
x86_64
3.10.0-693.2.2.el7.x86_64

cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

c. yum install libstdc++.so.6 (安装缺少的库)

unrar --help
unrar: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

d. yum provides libstdc++.so.6 ()
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
libstdc++-4.8.5-28.el7.i686 : GNU Standard C++ Library
Repo : base
Matched from:
Provides : libstdc++.so.6

libstdc++-4.8.5-28.el7_5.1.i686 : GNU Standard C++ Library
Repo : updates
Matched from:
Provides : libstdc++.so.6

e. yum install libstdc++.so.6 --setopt=protected_multilib=false

f. unrar
unrar: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

yum update libstdc++-4.8.5-16.el7.x86_64

unrar
unrar: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

yum install libstdc++.so.6 （走完这一步，好了终于可以用unrar了）

注释： 关于找到rar软件的下载地址，是受到 wget http://www.rarsoft.com/rar/rarlinux-3.9.3.tar.gz 的地址的启发。
