The official CLI is the first thing that comes into mind. You can install the CLI in different ways:

  1. Via the package redis-tools in Debian based distributions. This package might be outdated (depending on your OS). With Homebrew, this package is not available (there is a tap that looks unmaintained)
  2. As part of the package redis-server which includes Redis itself. This package might be outdated as well (depending on your OS) and installs the server component, which is not required.
  3. Form the tarball with make. This requires some packages like gcc and some time as it is build from source, which is not ideal.

Example call

redis-cli -h localhost -p 6379 [--tls --skipVerify -a <password>]


Redli is a humane alternative to redis-cli that looks unmaintained and does not offer a Darwin ARM build. M1 Mac users must build it themself.

Example call

redli -h localhost -p 6379 [--tls --skipverify -a <password>]

nc and ncat

You can use netcat (or nmap’s ncat) to check the connection as well!

export REDISAUTH=<password>
export REDISHOST=localhost
export REDISPORT=6379
echo -e "*2\r\n\$4\r\nAUTH\r\n\$16\r\n$REDISAUTH\r\n*2\r\n\$4\r\nINFO\r\n\$5\r\nSTATS\r\n" | [nc|ncat] $REDISHOST $REDISPORT

Unfortunately, this was not working on my machine.


Neither of these options was very pleasant on my M1 Mac, so I decided to write my own little helper tool to check the connection to a Redis data store.

The requirements were rather simple:

  • Go and cross-platform build including Darwin ARM. By providing a cross-platform binary, I can benefit from the same functionality on every system even without the need of root permissions to install packages.
  • Arguments to configure the address, TLS, skipVerify and a password.
  • Execute PING command to verify the connection.

Have a look at the repo and its releases for the result 😊
