Connection configuration in Redis - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to connect to Redis on the default host and port.

Redis

redis_client = redis.Redis(host=[1])

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

A"remotehost"

B"127.0.0.1"

C"localhost"

D"0.0.0.0"

💡 Hint

Common Mistakes

Using an IP address that is not local.

Leaving the host empty.

Redis usually runs on the local machine, so the host is "localhost".

2fill in blank

medium

Complete the code to connect to Redis on port 6380 instead of the default 6379.

Redis

redis_client = redis.Redis(port=[1])

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

A6379

B6380

C3306

D8080

Attempts:

3 left

💡 Hint

Common Mistakes

Using the default port 6379 by mistake.

Using unrelated port numbers like 3306 (MySQL) or 8080 (HTTP).

Port 6380 is the custom port we want to connect to instead of the default 6379.

3fill in blank

hard

Fix the error in the code by completing the password parameter to connect securely.

Redis

redis_client = redis.Redis(password=[1])

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

A"mypassword"

BTrue

C12345

DNone

Attempts:

3 left

💡 Hint

Common Mistakes

Using None which means no password.

Using a number or boolean instead of a string.

The password must be a string matching the Redis server password, here "mypassword".

4fill in blank

hard

Fill both blanks to connect to Redis on host "redis-server" and port 7000.

Redis

redis_client = redis.Redis(host=[1], port=[2])

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

A"redis-server"

B6379

C7000

D"localhost"

Attempts:

3 left

💡 Hint

Common Mistakes

Swapping host and port values.

Using default port 6379 instead of 7000.

We specify the host as "redis-server" and the port as 7000 to connect correctly.

5fill in blank

hard

Fill all three blanks to connect to Redis with host "cache", port 6381, and password "secret".

Redis

redis_client = redis.Redis(host=[1], port=[2], password=[3])

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

A"cache"

B6381

C"secret"

D6379

Attempts:

3 left

💡 Hint

Common Mistakes

Using default port 6379 instead of 6381.

Not quoting the password string.

We use the host "cache", port 6381, and password "secret" to connect securely.
