💡 Hint

Common Mistakes

Using 'enable' instead of 'start' will not start the service immediately.

Using 'stop' will turn off the service, which is the opposite of starting.

The start command launches the Elasticsearch service immediately.

💡 Hint

Common Mistakes

Using 'restart' will restart the service instead of showing status.

Using 'stop' will stop the service, which is not checking status.

The status command shows if Elasticsearch is running or stopped.

💡 Hint

Common Mistakes

Using 'remove' deletes packages instead of installing.

Using 'update' refreshes package lists but does not install.

The install command installs new packages like Elasticsearch.

4fill in blank

Fill both blanks to create a user and group for Elasticsearch.

Elasticsearch

sudo [1] elasticsearch && sudo [2] elasticsearch

Drag options to blanks, or click blank then click option'

Attempts:

💡 Hint

Common Mistakes

Creating the user before the group can cause errors.

Using 'usermod' or 'groupmod' modifies existing users/groups, not create.

First, create the group with groupadd, then create the user with useradd.

5fill in blank

hard

Fill all three blanks to configure Elasticsearch to start on boot and verify it.

Elasticsearch

sudo systemctl [1] elasticsearch && sudo systemctl [2] elasticsearch && sudo systemctl [3] elasticsearch

Drag options to blanks, or click blank then click option'

Aenable

Bstatus

Cstart

Ddisable

Attempts:

💡 Hint

Common Mistakes

Starting before enabling means it won't start on boot.

Checking status before starting shows it stopped.

First, enable sets Elasticsearch to start on boot, then start runs it now, and status checks if it is running.
