016_把普通用户免秘钥加入root用户的几种方式

一、第一种方式。

(1)

[root@infra-jyallkv-tikv-pps-7 ~]# tail /etc/sudoers
## Allows members of the users group to mount and unmount the
## cdrom as root
# %users ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom

## Allows members of the users group to shutdown this system
# %users localhost=/sbin/shutdown -h now

## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
#includedir /etc/sudoers.d
%sudo ALL=NOPASSWD:ALL

(2)

[root@infra-jyallkv-tikv-pps-7 ~]# usermod -a -G sudo ansible_shell    #不用从ansible_shell在其它组中移除而添加到新的sudo中

[root@infra-jyallkv-tikv-pps-7 ~]# egrep -nri "sudo" /etc/gshadow
50:sudo:!::tool.ops,ops,dev-super,dba,cideploy,ansible_shell

看到ansible_shell已经加到sudo组中了,这样su - ansible_shell中然后再执行"sudo su - root"就可以了

二、

直接在/etc/sudoers添加(未验证)

%ansible_shell ALL=NOPASSWD:ALL
