centos7设置root权限组

2019独角兽企业重金招聘Python工程师标准>>>

linux好多操作需要root权限，那应该怎么添加呢？

# cat /etc/sudoers   #查看sudoers
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows members of the 'sys' group to run networking, software,
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

由上面我们可知，简单的方法有两种，一是给指定用户添加所有权限，二是给将指定用户添加到wheel 即

weidd    ALL=(ALL)       ALL  #在/etc/sudoers中添加

或

# usermod -g wheel weidd  #设置weidd的主组为wheel
# id weidd
uid=1000(weidd) gid=10(wheel) 组=10(wheel),1000(weidd)
# cd / && sudo mkdir aaa   #这样我们就能在根目录任性的创建文件了
