Install Redis 7 Ubuntu


4 min read

Install on Ubuntu/Debian

You can install recent stable versions of Redis from the official APT repository.


If you're running a very minimal distribution (such as a Docker container) you may need to install lsb-release, curl and gpg first:

sudo apt install lsb-release curl gpg

Add the repository to the apt index, update it, and then install:

curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg

echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/redis.list

sudo apt-get update
sudo apt-get install redis

Testing Redis

As with any newly-installed software, it’s a good idea to ensure that Redis is functioning as expected before making any further changes to its configuration. We will go over a handful of ways to check that Redis is working correctly in this step.

Start by checking that the Redis service is running:

sudo systemctl status redis-server

Binding to localhost

By default, Redis is only accessible from localhost. However, if you installed and configured Redis by following a different tutorial than this one, you might have updated the configuration file to allow connections from anywhere. This is not as secure as binding to localhost.

To correct this, open the Redis configuration file for editing:

sudo nano /etc/redis/redis.conf

Locate this line and make sure it is uncommented (remove the # if it exists):

bind ::1

Save and close the file when finished (press CTRL + X, Y, then ENTER).

Then, restart the service to ensure that systemd reads your changes:

sudo systemctl restart redis-server

To check that this change has gone into effect, run the following netstat command:

sudo netstat -lnp | grep redis
tcp        0      0*               LISTEN      14222/redis-server  
tcp6       0      0 ::1:6379                :::*                    LISTEN      14222/redis-server

Note: The netstat command may not be available on your system by default. If this is the case, you can install it (along with a number of other handy networking tools) with the following command:

sudo apt install net-tools

Configuring a Redis Password

Configuring a Redis password enables one of its two built-in security features — the auth command, which requires clients to authenticate to access the database. The password is configured directly in Redis’s configuration file, /etc/redis/redis.conf, so open that file again with your preferred editor:

sudo nano /etc/redis/redis.conf

Scroll to the SECURITY section and look for a commented directive that reads:

. . .
# requirepass foobared
. . .

Uncomment it by removing the #, and change foobared to a secure password.

Note: Above the requirepass directive in the redis.conf file, there is a commented warning:

. . .
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
. . .

Thus, it’s important that you specify a very strong and very long value as your password. Rather than make up a password yourself, you can use the openssl command to generate a random one, as in the following example. By piping the output of the first command to the second openssl command, as shown here, it will remove any line breaks produced by that the first command:

openssl rand 60 | openssl base64 -A

Your output should look something like:


After copying and pasting the output of that command as the new value for requirepass, it should read:

requirepass RBOJ9cCNoGCKhlEBwQLHri1g+atWgn4Xn4HwNUbtzoVxAYxkiYBi7aufl4MILv1nxBqR4L6NNzI0X6cE

After setting the password, save and close the file, then restart Redis:

sudo systemctl restart redis-server

To test that the password works, open up the Redis client:


The following shows a sequence of commands used to test whether the Redis password works. The first command tries to set a key to a value before authentication:> set key1 10

That won’t work because you didn’t authenticate, so Redis returns an error:

Output> (error) NOAUTH Authentication required.

The next command authenticates with the password specified in the Redis configuration file:> auth your_redis_password

Redis acknowledges:


After that, running the previous command again will succeed:> set key1 10

get key1 queries Redis for the value of the new key.> get key1

After confirming that you’re able to run commands in the Redis client after authenticating, you can exit redis-cli:> quit
