我这个是自己的环境，各位配合自己的环境使用哦
1，检查sudo是否安装，如果安装直接配置就可以。
2，下载sudo，或者是用ftp
3，安装sudo
4，配置sudo
。。。。。。。在安装中是用源码安装的，一定要编译好，要不然找不到配置文件。下面的网址结合看会更明白。
安装和配置sudo ：http://linux.chinaunix.net/techdoc/install/2006/03/05/928431.shtml
1、输入sudo命令测试此linux系统是否安装了sudo工具，如果安装，直接编辑配置文件
# sudo ------------------看一下是否安装了sudo
usage: sudo -V | -h | -L | -l | -v | -k | -K | [-H] [-P] [-S] [-b] [-p prompt]
[-u username/#uid] -s |
2、下载sudo

3、安装sudo
# tar -xvf sudo-1.6.7p5.tar ------------解压sudo
# cd /tmp/sudo-1.6.7p5
# ./configure --prefix=/usr/local/sudo --bindir=/usr/bin --sbindir=/usr/sbin --mandir=/usr/share/man --sysconf=/etc ------------------编译sudo，visudo，man的配置文件
# make
# make installn
4、编辑配置文件
进入/etc修改/sudoers配置文件
cs_svr17[/]#cd /etc ------------进入/etc
cs_svr17[/etc]#pwd
/etc
cs_svr17[/etc]#ll sudo*--------------查看sudo的文件，找到sudoers
-r--r----- 1 root root 580 May 31 20:39 sudoers
cs_svr17[/etc]#cat sudoers------------查看sudoers
我是直接执行visudo的命令
#visudo
软件从源码包安装过程：
./configure #编译sudo软件
make#执行编译sudo软件
make install#安装编译sudo软件
export PATH=$PATH:/usr/local/bin:/usr/local/sbin #修改可执行文件的查找路径
which sudo#查找可执行软件所在位置
sudo --help -------------检查sudo已经安装
export PATH=$PATH:/usr/local/bin:/usr/local/sbin----如果没有编译，就需要零时添加变量到 profile
或者是永久添加变量# vi /etc/profile
