Could not connect to Redis at Connection refused with homebrew

After installing redis, type from terminal:


And Redis-Server will be started

I found this question while trying to figure out why I could not connect to redis after starting it via brew services start redis.


Depending on how fresh your machine or install is you're likely missing a config file or a directory for the redis defaults.

  1. You need a config file at /usr/local/etc/redis.conf. Without this file redis-server will not start. You can copy over the default config file and modify it from there with

    cp /usr/local/etc/redis.conf.default /usr/local/etc/redis.conf
  2. You need /usr/local/var/db/redis/ to exist. You can do this easily with

    mkdir -p /usr/local/var/db/redis

Finally just restart redis with brew services restart redis.

How do you find this out!?

I wasted a lot of time trying to figure out if redis wasn't using the defaults through homebrew and what port it was on. Services was misleading because even though redis-server had not actually started, brew services list would still show redis as "started." The best approach is to use brew services --verbose start redis which will show you that the log file is at /usr/local/var/log/redis.log. Looking in there I found the smoking gun(s)

Fatal error, can't open config file '/usr/local/etc/redis.conf'


Can't chdir to '/usr/local/var/db/redis/': No such file or directory

Thankfully the log made the solution above obvious.

Can't I just run redis-server?

You sure can. It'll just take up a terminal or interrupt your terminal occasionally if you run redis-server &. Also it will put dump.rdb in whatever directory you run it in (pwd). I got annoyed having to remove the file or ignore it in git so I figured I'd let brew do the work with services.

If aftre install you need run redis on all time, Just type in terminal:

redis-server &

Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:

sudo apt-get install redis-server

That will create a redis user and install the init.d script for it. Since upstart is now the replacement for using init.d, I figure I should convert it to run using upstart.

To disable the default init.d script for redis:

sudo update-rc.d redis-server disable

Then create /etc/init/redis-server.conf with the following script:

description "redis server"

start on runlevel [23]
stop on shutdown

exec sudo -u redis /usr/bin/redis-server /etc/redis/redis.conf


What this is is the script for upstart to know what command to run to start the process. The last line also tells upstart to keep trying to respawn if it dies.

One thing I had to change in /etc/redis/redis.conf is to change daemonize yes to daemonize no. What happens if you don't change it is that redis-server will fork and daemonize itself, and the parent process goes away. When this happens, upstart thinks that the process has died/stopped and you won't have control over the process from within upstart.

Now you can use the folowing commands to control your redis-server:

sudo start redis-server
sudo restart redis-server
sudo stop redis-server

Hope this was helpful!

It's the better way to connect to your redis.

At first, check the ip address of redis server like this.

ps -ef | grep redis

The result is kind of " redis 1184 1 0 .... /usr/bin/redis-server 172.x.x.x:6379

And then you can connect to redis with -h(hostname) option like this.

redis-cli -h 172.x.x.x


In my case, it was the password that contained some characters like ', after changing it the server started without problems.

I just had this same problem because I had used improper syntax in my config file. I meant to add:

maxmemory-policy allkeys-lru

to my config file, but instead only added:


which evidently prevented Redis from parsing the config file, which in turn prevented me from connecting through the cli. Fixing this syntax allowed me to connect to Redis.

Had that issue with homebrew MacOS the problem was some sort of permission missing on /usr/local/var/log directory see issue here

In order to solve it I deleted the /usr/local/var/log and reinstall redis brew reinstall redis

First you need to up/start the all the redis nodes using below command, one by one for all conf files. @Note : if you are setting up cluster then you should have 6 nodes, 3 will be master and 3 will be slave.redis-cli will automatically select master and slave out of 6 nodes using --cluster command as shown in my below commands.

[[email protected] redis-stable]$ redis-server xxxx.conf 

then run

[[email protected] redis-stable]$ redis-cli --cluster create --cluster-replicas 1

output of above should be like:

    >>> Performing hash slots allocation on 6 nodes...

2nd way to set up all things automatically: you can use utils/create-cluster scripts to set up every thing for you like starting all nodes, creating cluster you an follow
