CentOS赋予用户使用sudo等命令的权利
1. 取得root权限
su root
2. 编辑sudoers文件
命令:visudo或者vi /etc/sudoers
3. 为用户添加root所有权限
## Next comes the main part: which users can run what software on
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
## user MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
在此之后添加一行代码:ting ALL=(ALL) ALL
