The Red Hat Certified Engineer (RHCE) exam for Red Hat Enterprise Linux 8 (EX294)

Create a playbook called hwreport.yml that produces an output file called /root/

hwreport.txt on all managed nodes with the following information:

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

-- > Inventory host name

-- > Total memory in MB

-- > BIOS version

-- > Size of disk device vda

-- > Size of disk device vdb

Each line of the output file contains a single key-value pair.

* Your playbook should:

-- > Download the file hwreport.empty from the URL http://classroom.example.com/

hwreport.empty and

save it as /root/hwreport.txt

-- > Modify with the correct values.

note: If a hardware item does not exist, the associated value should be set to NONE

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

while practising you to create these file hear. But in exam have to download as per

questation.

hwreport.txt file consists.

my_sys=hostname

my_BIOS=biosversion

my_MEMORY=memory

my_vda=vdasize

my_vdb=vdbsize

Rekey an existing Ansible vault as follows:

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

* Download Ansible vault from http:// classroom.example.com /secret.yml to /home/

admin/ansible/

* The current vault password is curabete

* The new vault password is newvare

* The vault remains in an encrypted state with the new password

Install the RHEL system roles package and create a playbook called timesync.yml that:

-- > Runs over all managed hosts.

-- > Uses the timesync role.

-- > Configures the role to use the time server 192.168.10.254 ( Hear in redhat lab

use " classroom.example.com " )

-- > Configures the role to set the iburst parameter as enabled.

Install and configure Ansible on the control-node control.realmX.example.com as

follows:

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

-- > Install the required packages

-- > Create a static inventory file called /home/admin/ansible/inventory as follows:

node1.realmX.example.com is a member of the dev host group

node2.realmX.example.com is a member of the test host group

node3.realmX.example.com & node4.realmX.example.com are members of the prod

host group

node5.realmX.example.com is a member of the balancers host group.

prod group is a member of the webservers host group

-- > Create a configuration file called ansible.cfg as follows:

-- > The host inventory file /home/admin/ansible/inventory is defined

-- > The location of roles used in playbooks is defined as /home/admin/ansible/ roles

Create a playbook called issue.yml in /home/sandy/ansible which changes the file /etc/issue on all managed nodes: If host is a member of (lev then write " Development " If host is a member of test then wri te " Test " If host is a member of prod then write " Production "

Create a file called specs.empty in home/bob/ansible on the local machine as follows:

HOST=

MEMORY=

BIOS=

VDA_DISK_SIZE=

VDB_DISK_SIZE=

Create the playbook /home/bob/ansible/specs.yml which copies specs.empty to all remote nodes ' path /root/specs.txt. Using the specs.yml playbook then edit specs.txt on the remote machines to reflect the appropriate ansible facts.

Create a file called requirements.yml in /home/sandy/ansible/roles to install two roles. The source for the first role is geerlingguy.haproxy and geerlingguy.php. Name the first haproxy-role and the second php-role. The roles should be installed in /home/sandy/ansible/r oles.

Create a role called sample-apache in /home/sandy/ansible/roles that enables and starts httpd, enables and starts the firewall and allows the webserver service. Create a template called index.html.j2 which creates and serves a message from /var/www/html/index.html Whenever the content of the file changes, restart the webserver service.

Welcome to [FQDN] on [IP]

Replace the FQDN with the fully qualified domain name and IP with the ip address of the node using ansible facts. Lastly, create a playbook in /home/sandy/ansible/ called apache.yml and use the role to serve the index file on webserver hosts.

Create a file in /home/sandy/ansible/ called report.yml. Using this playbook, get a file called report.txt (make it look exactly as below). Copy this file over to all remote hosts at /root/report.txt. Then edit the lines in the file to provide the real information of the hosts. If a disk does not exist then write NONE.
