安裝軟件：

# yum install -y automake autoconf
# yum install -y intltool
# yum install -y libtool
# yum install -y gcc-c++
# yum install -y unzip wget
# yum install -y bison
# yum install -y gperf
# yum install -y texinfo

編譯步驟：
1.# git clone -b v8.22 https://github.com/coreutils/coreutils.git
2.# unzip coreutils-8.22.zip
3.# cd coreutils-8.22
下面的步驟需要在非root用戶下運行，所以先創建一個用戶
4.# useradd -d /home/chen chen
5.# passwd chen
修改權限

1.切換到root用戶下,怎麼切換就不用說了吧,不會的自己百度去.

2.添加sudo文件的寫權限,命令是:
chmod u+w /etc/sudoers

3.編輯sudoers文件
vi /etc/sudoers
找到這行 root ALL=(ALL) ALL,在他下面添加xxx ALL=(ALL) ALL (這裏的xxx是你的用戶名)

ps:這裏說下你可以sudoers添加下面四行中任意一條
youuser            ALL=(ALL)                ALL
%youuser           ALL=(ALL)                ALL
youuser            ALL=(ALL)                NOPASSWD: ALL
%youuser           ALL=(ALL)                NOPASSWD: ALL

第一行:允許用戶youuser執行sudo命令(需要輸入密碼).
第二行:允許用戶組youuser裏面的用戶執行sudo命令(需要輸入密碼).
第三行:允許用戶youuser執行sudo命令,並且在執行的時候不輸入密碼.
第四行:允許用戶組youuser裏面的用戶執行sudo命令,並且在執行的時候不輸入密碼.

4.撤銷sudoers文件寫權限,命令:
chmod u-w /etc/sudoers

這樣普通用戶就可以使用sudo了.

切換到普通用戶
6.$ ./bootstrap
7.$ ./configure
8.$ make
9.$ make install
