Perintah sudo di Fedora

Atribut sudo biasanya di pakai untuk write-read-execute suatu file atau direktori, di Ubuntu default saat kita membuat user pertama kali di saat install maka "sudo" sudah bisa dipakai namun bagaimana dengan fedora? di Fedora tidak begitu, kita harus menambahkan secara manual hak sudo pada suatu user baru bisa dipakai.

Hampir sama seperti di Ubuntu linux, kita hanya cukup mengedit file sudoers di /etc/sudoers lalu menambahkan option hingga sampai kurang-lebih seperti berikut :

## 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/mii-tool

## Installation and management of software

# Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum

## Services

# Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig

## 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

#

# Disable "ssh hostname sudo ", because it will show the password in clear.
# You have to run "ssh -t hostname sudo ".
#
Defaults requiretty

Defaults env_reset
Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC 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"

Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/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.
##
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
ncuptea 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

## Same thing without a password
# %wheel ALL=(ALL) NOPASSWD: ALL

## 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


Catatan :

• Untuk menghindari hal-hal yang tidak di inginkan, silahkan backup terlebih dahulu. Misal :
  # cp /etc/sudoers /etc/sudoers.asli
• Yang di tandai merah ialah yang ditambahkan oleh kita.
• Yang di cetak tebal berwarna merah ialah user, kebetulan di saya usernya ialah "ncuptea".
