This sample /etc/sudoers file is only for reference.
## Sudoers allows particular users to run various commands
as
## the root user, without needing the root password.
##
## Examples are provided at the bottom of the file for
collections
## of related commands, which can then be delegated out to
particular
## users or groups.
##
## This file must be edited with the 'visudo' command.
## Host Aliases
## Groups of machines. You may prefer to use hostnames
(perhaps using
## wildcards for entire domains) or IP addresses instead.
# Host_Alias FILESERVERS = fs1, fs2
# Host_Alias MAILSERVERS = smtp, smtp2
## User Aliases
## These aren't often necessary, as you can use regular
groups
## (ie, from files, LDAP, NIS, etc) in this file - just use
%groupname
## rather than USERALIAS
# User_Alias ADMINS = jsmith, mikem
## Command Aliases
## These are groups of related commands...
## Networking
# Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig,
/bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables,
/usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/miitool
## Installation and management of software
# Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date,
/usr/bin/yum
## Services
# Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig,
/usr/bin/systemctl start, /usr/bin/systemctl stop, /usr/bin/
systemctl reload, /usr/bin/systemctl restart, /usr/bin/
systemctl status, /usr/bin/systemctl enable, /usr/bin/
systemctl disable
## Updating the locate database
# Cmnd_Alias LOCATE = /usr/bin/updatedb
## Storage
# Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/
parted, /sbin/partprobe, /bin/mount, /bin/umount
## Delegating permissions
# Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown,
/bin/chmod, /bin/chgrp
## Processes
# Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/
kill, /usr/bin/killall
## Drivers
# Cmnd_Alias DRIVERS = /sbin/modprobe
# Defaults specification

Refuse to run if unable to disable echo on the tty.

##
Preserving HOME has security implications since many
programs
# use it when searching for configuration files. Note that
HOME
# is already set when the the env_reset option is enabled,
so
# this option is only effective for configurations where
either
# env_reset is disabled or HOME is present in the env_keep
list.
#D
efaults always_set_home
Defaults match_group_by_gid
# Prior to version 1.8.15, groups listed in sudoers that
were not
# found in the system group database were passed to the
group
# plugin, if any. Starting with 1.8.15, only groups of the
form
# %:group are resolved via the group plugin by default.
# We enable always_query_group_plugin to restore old
behavior.
# Disable this option for new behavior.
Defaults always_query_group_plugin
Defaults env_reset
Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE
KDEDIR LS_COLORS"
Defaults env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG
LC_ADDRESS LC_CTYPE"
Defaults env_keep += "LC_COLLATE LC_IDENTIFICATION
LC_MEASUREMENT LC_MESSAGES"
Defaults env_keep += "LC_MONETARY LC_NAME LC_NUMERIC
LC_PAPER LC_TELEPHONE"
Defaults env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS
_XKB_CHARSET XAUTHORITY"
##
Adding HOME to env_keep may enable a user to run
unrestricted
# commands via sudo.
##
Defaults env_keep += "HOME"
#Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
Defaults secure_path="/usr/local/sbin:/usr/local/
bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
## 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.
