Instead of redis-cli you can simply use nc!

nc -v --ssl redis.mydomain.com 6380

Then submit the commands.

From

wget 
tar xvzf redis-stable.tar.gz
cd redis-stable
make redis-cli
sudo cp src/redis-cli /usr/local/bin/

With Docker I normally use . If I need to add redis-cli to an image I use the following snippet.

RUN cd /tmp &&\
    curl  | tar xz &&\
    make -C redis-stable &&\
    cp redis-stable/src/redis-cli /usr/local/bin &&\
    rm -rf /tmp/redis-stable

To install 3.0 which is the latest stable version:

$ git clone  
$ cd redis && git checkout 3.0 
$ make redis-cli 

Optionally, you can put the compiled executable in your load path for convenience:

$ ln -s src/redis-cli /usr/local/bin/redis-cli

In my case, I have to run some more steps to build it on RedHat or Centos.

# get system libraries
sudo yum install -y gcc wget

# get stable version and untar it
wget 
tar xvzf redis-stable.tar.gz
cd redis-stable

# build dependencies too!
cd deps
make hiredis jemalloc linenoise lua geohash-int
cd ..

# compile it
make

# make it globally accesible
sudo cp src/redis-cli /usr/bin/

For centOS, maybe can try following steps

cd /tmp
wget 
tar xvzf redis-stable.tar.gz
cd redis-stable
make
cp src/redis-cli /usr/local/bin/
chmod 755 /usr/local/bin/redis-cli

Using Docker, you may run this command to get Redis CLI:

docker run -it --rm redis:alpine redis-cli -h redis.mycompany.org -p 6379

where redis is the redis docker image from Docker Hub,
redis-cli is pre-installed in that image, and all after that are parameters to redis-cli:
-h is hostname to connect to,
-p is apparently the port to connect to.

You could also create an alias using the above command

alias redis-cli='docker run --rm --network=host redis:alpine redis-cli'

Which could be added to .bashrc if your using Bash

You can also use telnet instead

telnet redis-host 6379

And then issue the command, for example for monitoring

monitor

To expand on @Agis's answer, you can also install the Redis CLI by running

$ git clone -b v2.8.7 :antirez/redis.git
$ make -C redis install redis-cli /usr/bin

This will build the Redis CLI and toss the binary into /usr/bin. To anyone who uses Docker, I've also built a Dockerfile that does this for you:

For Amazon Linux

#sudo amazon-linux-extras install redis6
#redis-cli

2022 answer:

git clone 
cd redis/src/
make redis-cli
sudo cp redis-cli /usr/bin/redis-cli
redis-cli --version

worked for me.

you may scp it from your redis machine if you have one, its just single binary. Or copy with nc if private network (this method is insecure):

redisclient: nc -l 8888 > /usr/local/bin/redis-cli
redisserver: cat /usr/local/bin/redis-cli | nc redisclient 8888

I made a simple pure-go solution, which is under development.

redis-cli:

Build once, and run everywhere. Fully portable.

Please feel free to have a try.

There are many way to install radis-cli. It comes with redis-tools and redis-server. Installing any of them will install redis-cli too. But it will also install other tools too. As you have redis-server installed somewhere and only interested to install redis-cli. To install install only redis-cli without other unnecessary tools follow below command

cd /tmp
wget 
tar xvzf redis-stable.tar.gz
cd redis-stable
make
cp src/redis-cli /usr/local/bin/
chmod 755 /usr/local/bin/redis-cli

# get system libraries
sudo yum install -y gcc wget

# get stable version and untar it
wget 
tar xvzf redis-stable.tar.gz
cd redis-stable
make redis-cli

If the build fails / make command fails, then :

Removing all line with _Atomic from src/server.h and src/networking.c should makes the compile complete.

# make it globally accesible
sudo cp src/redis-cli /usr/local/bin/

for CentOS to get redis-cli without compiling it you can fetch Redis rpm from Epel repo and extract just ths tool. Here's step by step instruction

yum install -y jemalloc
yum install -y yum-utils
# NOTE - EPEL REPO MUST BE INSTALLED AND ENABLED
RPM_URL=$(yumdownloader --urls redis | tail -n1)
RPM=$(basename $RPM_URL)
mkdir /tmp/redis
cd /tmp/redis
wget $RPM_URL
rpm2cpio $RPM | cpio -idmv "./usr/bin/redis-cli"
mv ./usr/bin/redis-cli /usr/bin/redis-cli
rm -rf /tmp/redis
/usr/bin/redis-cli --version

There's a script that automatically download, build and install the latest redis-cli on Ubuntu 20.04 LTS.

To run it, copy and paste this on your terminal.

curl -sL "" | bash

Or wget, in case you don't have curl installed.

wget -qO - "" | bash

Feel free to look the source code:

PS.: I'm the author of this script.
