Install Sudo on RHEL, Fedora, Centos

| Comments

If you are using RHEL (any version of Redhat from what I know, but if I am wrong please let me know) Fedora or Centos, you don’t have to do anything special. sudo is installed by default and you will already have it on the system.

Configuration files:

/etc/sudoers

Default configuration:

# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults specification

# User privilege specification
root        ALL=(ALL) ALL

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

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

# Samples
# %usersĀ  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %usersĀ  localhost=/sbin/shutdown -h now

So not much information here… You might want to check the sudo article on how you can use this.
