Using homebrew to install Redis but when I try to ping Redis it shows this error:
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Note : I tried to turn off firewall and edit conf file but still cannot ping. I am using macOS Sierra and homebrew version 1.1.11
This question is related to
redis
redis-server
Try this :
sudo service redis-server restart
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.
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
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
.
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'
or
Can't chdir to '/usr/local/var/db/redis/': No such file or directory
Thankfully the log made the solution above obvious.
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.
In my case, it was the password that contained some characters like '
, after changing it the server started without problems.
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
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
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:
allkeys-lru
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.
Error connecting Redis on Apple Silicon( Macbook Pro M1 - Dec 2020), you have to just know 2 things:
shell% sudo redis-server
shell% sudo redis-server --daemonize yes
Verify using below steps:
shell% redis-cli ping
Hope this helps all Macbook Pro M1 users who are really worried about lack of documentation on this.
I was stuck on this for a long time. After a lot of tries I was able to configured it properly.
There can be different reasons of raising the error. I am trying to provide the reason and the solution to overcome from that situation.
6379 Port
is not allowed by ufw firewall.
Solution: type following command sudo ufw allow 6379
The issue can be related to permission of redis
user. May be redis user doesn't have permission of modifying necessary redis
directories. The redis
user should have permissions in the following directories:
/var/lib/redis
/var/log/redis
/run/redis
/etc/redis
To give the owner permission to redis
user, type the following commands:
sudo chown -R redis:redis /var/lib/redis
sudo chown -R redis:redis /var/log/redis
sudo chown -R redis:redis /run/redis
sudo chown -R redis:redis /etc/redis
.Now restart redis-server
by following command:
sudo systemctl restart redis-server
Hope this will be helpful for somebody.
In my case, someone had come along and incorrectly edited the redis.conf file to this:
bind 127.0.0.1 ::1
bind 192.168.1.7
when, it really needed to be this (one line):
bind 127.0.0.1 ::1 192.168.1.7
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.
[xxxxx@localhost redis-stable]$ redis-server xxxx.conf
then run
[xxxxx@localhost redis-stable]$ redis-cli --cluster create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 --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 https://redis.io/topics/cluster-tutorial
Thanks
Just like Aaron, in my case brew services list
claimed redis was running, but it wasn't. I found the following information in my log file at /usr/local/var/log/redis.log
:
4469:C 28 Feb 09:03:56.197 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
4469:C 28 Feb 09:03:56.197 # Redis version=4.0.9, bits=64, commit=00000000, modified=0, pid=4469, just started
4469:C 28 Feb 09:03:56.197 # Configuration loaded
4469:M 28 Feb 09:03:56.198 * Increased maximum number of open files to 10032 (it was originally set to 256).
4469:M 28 Feb 09:03:56.199 # Creating Server TCP listening socket 192.168.161.1:6379: bind: Can't assign requested address
That turns out to be caused by the following configuration:
bind 127.0.0.1 ::1 192.168.161.1
which was necessary to give my VMWare Fusion virtual machine access to the redis server on macOS, the host. However, if the virtual machine wasn't started, this binding failure caused redis not to start up at all. So starting the virtual machine solved the problem.
This work for me :
sudo service redis-server start
If after install you need to 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
respawn
What this 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 daemonize yes
to daemonize no
. What happens if you don't change it then 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 following commands to control your redis-server
:
sudo start redis-server
sudo restart redis-server
sudo stop redis-server
Hope this was helpful!
