RHCSA-Test

Files for practicing RHCSA exam

These tasks are based on the competencies that Red Hat has set forth. All files, test, labs, etc were handcrafted by myself.

The RHCSA Competencies for RHEL8 are included in the "rhcsa_competencies" file.

Follow the instructions in the file "rhcsa_rubric".

These files are untested and should be considered as an "alpha" release. Use at your own risk.

Lab Setup:

Create three vms:

• RH-Wkstn (Workstation w/ GUI)
• RH-CSA-1 (Server w/ no GUI)
• RH-CSA-2 (Server w/ no GUI)

Set grub time out to be longer on the two servers to make it easier to fix issues:

# sed -i 's/GRUB_TIMEOUT=5/GRUB_TIMEOUT=30/' /etc/default/grub
# grub2-mkconfig -o /boot/grub2/grub.cfg

Create a CPU hog on RH-CSA-1:

# dd if=/dev/zero of=/dev/null &

Add three spare hdds to RH-CSA-2:

• Two with 2G
• One with 5G

Create "rhat" user on RH-Wkstn, passwd rhat to Redhat123:

# useradd rhat
# passwd rhat

RH-CSA-1 should have a bad root password of NotAgoodOne:

# passwd

RH-CSA-2 root password is Redhat123:

# passwd

RH-CSA-1 should boot into graphical.target:

# systemctl set-default graphical.target

RH-CSA-2 should have a corrupt fstab:

# echo 'BadDriveLine /fake/drive  /fake/mount nfs defaults    0 0' >> /etc/fstab

Set timezone to America/Jamaica on both:

# timedatectl set-timezone America/Jamaica

Set RH-CSA-1 to be "Desktop":

# tuned-adm profile desktop

Create index.html on RH-CSA-2:

# echo "This is the content of the web server. Congrats!" > index.html
# tar -cvjf containers.tar.bzip2 index.html
# rm index.html

Ensure the IP settings are reverted back to null:

nmtui

Remove all traces of history:

# su - rhat
$ rm -rvf ~/.bash_history
$ history -c
$ exit
# rm -rvf /root/.bash_history
# history -c
