将一个账号开通sudo权限
打开`vim /etc/sudoers`
找开`root`这一行，加上
`root ALL=(ALL:ALL) ALL`
`test ALL=(ALL:ALL)ALL`
#victor ALL = /bin/more /etc/shadow
#victor ALL = NOPASSWD: /bin/more /etc/shadow
#victor ALL=(ALL:ALL) ALL
`victor ALL=(ALL:ALL) NOPASSWD: ALL`
#yanisyu localhost=NOPASSWD:/sbin/init
#yanisyu localhost=NOPASSWD:/usr/sbin/useradd
`yanisyu ALL=(ALL) NOPASSWD: ALL`
