EX200 Exam Dumps - RedHat RHCSA Questions and Answers

Solution:

dnf install -y httpd policycoreutils-python-utils

mkdir -p /webdata

echo "RHEL10 Web Server" > /webdata/index.html

sed -i 's/^Listen 80/Listen 8080/' /etc/httpd/conf/httpd.conf

semanage port -a -t http_port_t -p tcp 8080

firewall-cmd --permanent --add-port=8080/tcp

firewall-cmd --reload

systemctl enable --now httpd

systemctl restart httpd

ss -tulpn | grep 8080

Detailed Explanation:

Apache defaults to port 80, so Listen 8080 changes the service port.

SELinux must allow Apache to bind to 8080, which is done with semanage port.

firewall-cmd opens the port externally.

RHEL 10 documents firewalld as the standard firewall management interface and SELinux port labeling for confined services. ( Red Hat Documentation )

Solution:

dd if=/dev/zero of=/swapfile bs=1M count=512

chmod 600 /swapfile

mkswap /swapfile

swapon /swapfile

echo "/swapfile swap swap defaults 0 0" > > /etc/fstab

swapon --show

Detailed Explanation:

dd creates the file.

chmod 600 protects swap contents.

mkswap prepares the file as swap.

swapon activates it now.

/etc/fstab ensures it is enabled at boot.
