15 RHCSA9 | EX200 Exam | autofs

Question 15
Perform following task on "node02" as "rhcsa9" user

Configure autofs to automount the home directories of user "userautofs01".

Note the following:
server01.rhcsa9.momer.io(10.10.10.91), NFS-exports /shared to your system,
userautofs01 home directory is server01.rhcsa9.momer.io:/shared/userautofs01
userautofs01 home directory should be auto mounted locally at "/shared" as "/shared/userautofs01"
Home directories must be writable by the users when you login as "userautofs01" on "node02"


Solution 15

#######################################
--configure nfs server share directory
#######################################

-- Install required packages
sudo dnf install -y nfs* rpc*

-- enable and start nfs-server
sudo systemctl enable --now nfs-server
sudo systemctl status nfs-server

-- create shared directory
sudo mkdir /shared
sudo chmod 777 /shared

-- configure nfs share
sudo vi /etc/exports
/shared 10.10.10.93(rw,no_root_squash)

-- export nfs-share
sudo exportfs -avr

-- configure firewall
sudo firewall-cmd --add-service={nfs,mountd,rpc-bind} --permanent
sudo firewall-cmd --reload

-- create a user for demo purpose
sudo groupadd -g 1234 autofsusers
sudo useradd -d /shared/userautofs01 -u 1234 -g autofsusers userautofs01
sudo passwd userautofs01


#######################################
--configure autofs on node02
#######################################

user "userautofs01" must already be present on node02
we will create identical group and user on node02 as it is expected to be present on node02 server

sudo groupadd -g 1234 autofsusers
sudo useradd -d /shared/userautofs01 -u 1234 -g autofsusers userautofs01
sudo passwd userautofs01

---------------------------------------------------------------------------

Install the autofs package if it is not already installed:

sudo yum install -y autofs nfs-utils

Edit the autofs master configuration file using a text editor. For example:

sudo vi /etc/auto.master

Add the following line to the end of the file:

/shared /etc/auto.shared


Create a new configuration file /etc/auto.shared using a text editor:

sudo vi /etc/auto.shared

Add the following line to the file:

-rw,soft,intr server01.rhcsa9.momer.io:/shared/&

Save the changes to the file and exit the text editor.
Reload the autofs configuration for the changes to take effect:

sudo systemctl restart autofs

Verify that the home directory is mounted correctly by switching the user on node02

su - userautofs01

This command should show the contents of the userautofs01 home directory.
