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!

This work for me :

sudo service redis-server start

Answer 3

After installing redis, type from terminal:

redis-server

And Redis-Server will be started

Answer 4

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.

1. 6379 Port is not allowed by ufw firewall.

   Solution: type following command sudo ufw allow 6379

2. 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.

Answer 5

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

Answer 6

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
