the password to user1234
useradd -u 2929
passwd
task 11
Create a directory called dir1 under /var/tmp with
ownership and owning group set to root. Configure default ACLs on
the directory and give user10 read, write, and execute permissions

chown root:root /var/tmp/dir1
getfacl -c dir1
setfacl -dm u:user10:rwx dir1/
task 12
Attach the RHEL 8 ISO image to the VM and mount it persistently to /mnt/cdrom. Define access to both repositories and confirm
attach RHEL iso image to vitual box
edit fstab: /dev/sr0 /mnt iso9660 ro 0 0
sudo mount -a
Create a definition file called local.repo in the /etc/yum.repos.d directory
using the vim editor and define the following data for both repositories in
it:
[BaseOS]
name=BaseOS
baseurl=file://mnt/BaseOS
gpgcheck=0
[AppStream]
name=AppStream
baseurl=file;//mnt/AppStream
gpgcheck=0
sudo dnf repolist
task 13
Create a logical volume called lvol1 of size 280MB in vgtest
volume group. Mount the ext4 file system persistently to /mnt/mnt1
sudo parted /dev/sdd mklabel msdos
sudo parted /dev/sdd mkpart primary 1 280m
sudo parted /dev/sdd set 1 lvm on
sudo pvcreate /dev/sd1
sudo vgcreate -vs 16 vgtest /dev/sdd
sudo lvcreate –n lvol1 -L 280 vgtest
sudo mkfs.ext4 /dev/vgtest/lvol1
fstab:
/dev/vgtest/lvol1 /mnt ext4 defaults 0 0
sudo mount -a
task 14
Change group membership on /mnt/mnt1 to group10. Set
read/write/execute permissions on /mnt/mnt1 for group members,
and revoke all permissions for public
chown :group10 /mnt/mnt1
chmod g=rwx,o= /mnt/mnt1
task 15
Create a logical volume called lvswap of size 280MB in
vgtest volume group. Initialize the logical volume for swap use. Use
the UUID and place an entry for persistence
sudo parted /dev/sdb mkpart primary 0 280m
sudo lvcreate -L 280 -n lvswap vgtest
sudo mkswap /dev/vgtest/lvswap
lsblk -f /dev/vgfs/swapvol
fstab: UUID=”A;LSDKF” swap swap pri=1 0 0
sudo swapon -a
