redis-cli

Run Redis commands.

The redis-cli command-line utility lets you interact with a Redis database. With redis-cli, you can run Redis commands directly from the command-line terminal or with interactive mode.

If you want to run Redis commands without redis-cli, you can connect to a database with Redis Insight and use the built-in CLI prompt instead.

Install redis-cli

When you install Redis Enterprise Software or Redis Community Edition, it also installs the redis-cli command-line utility.

To learn how to install Redis and redis-cli, see the following installation guides:

Connect to a database

To run Redis commands with redis-cli, you need to connect to your Redis database.

You can find endpoint and port details in the Databases list or the database’s Configuration screen.

Connect remotely

If you have redis-cli installed on your local machine, you can use it to connect to a remote Redis database. You will need to provide the database's connection details, such as the hostname or IP address, port, and password.

$ redis-cli -h <endpoint> -p <port> -a <password>

You can also provide the password with the REDISCLI_AUTH environment variable instead of the -a option:

$ export REDISCLI_AUTH=<password>
$ redis-cli -h <endpoint> -p <port>

Connect over TLS

To connect to a Redis Enterprise Software or Redis Cloud database over TLS:

  1. Download or copy the Redis Enterprise server (or proxy) certificates.

    • For Redis Cloud, see Download certificates for detailed instructions on how to download the server certificates (redis_ca.pem) from the Redis Cloud console.

    • For Redis Enterprise Software, copy the proxy certificate from the Cluster Manager UI (Cluster > Security > Certificates > Server authentication) or from a cluster node (/etc/opt/redislabs/proxy_cert.pem).

  2. Copy the certificate to each client machine.

  3. If your database doesn't require client authentication, provide the Redis Enterprise server certificate (redis_ca.pem for Cloud or proxy_cert.pem for Software) when you connect:

    redis-cli -h <endpoint> -p <port> --tls --cacert <redis_cert>.pem

  4. If your database requires client authentication, provide your client's private and public keys along with the Redis Enterprise server certificate (redis_ca.pem for Cloud or proxy_cert.pem for Software) when you connect:

    redis-cli -h <endpoint> -p <port> --tls --cacert <redis_cert>.pem \
    --cert redis_user.crt --key redis_user_private.key

Connect with Docker

If your Redis database runs in a Docker container, you can use docker exec to run redis-cli commands:

$ docker exec -it <Redis container name> redis-cli -p <port>

Basic use

You can run redis-cli commands directly from the command-line terminal:

$ redis-cli -h <endpoint> -p <port> <Redis command>

For example, you can use redis-cli to test your database connection and store a new Redis string in the database:

$ redis-cli -h <endpoint> -p 12000 PING
PONG
$ redis-cli -h <endpoint> -p 12000 SET mykey "Hello world"
OK
$ redis-cli -h <endpoint> -p 12000 GET mykey              
"Hello world"

For more information, see Command line usage.

Interactive mode

In redis-cli interactive mode, you can:

  • Run any redis-cli command without prefacing it with redis-cli.
  • Enter ? for more information about how to use the HELP command and set redis-cli preferences.
  • Enter HELP followed by the name of a command for more information about the command and its options.
  • Press the Tab key for command completion.
  • Enter exit or quit or press Control+D to exit interactive mode and return to the terminal prompt.

This example shows how to start interactive mode and run Redis commands:

$ redis-cli -p 12000
127.0.0.1:12000> PING
PONG
127.0.0.1:12000> SET mykey "Hello world"
OK
127.0.0.1:12000> GET mykey
"Hello world"

Examples

Check slowlog

Run slowlog get for a list of recent slow commands:

redis-cli -h <endpoint> -p <port> slowlog get <number of entries>

Scan for big keys

Scan the database for big keys:

redis-cli -h <endpoint> -p <port> --bigkeys

See Scanning for big keys for more information.
