While working through the Pakyow "warmup" tutorial, I encountered the error
Redis::CannotConnectError. I'm on macOS and installed Redis via homebrew. Do I perhaps need to start a Redis server manually?
Yep redis needs to be running. Just run redis-server from the command line and you should be good to go!

I have a Ubuntu 14.04 which run an app supported by Docker (version 17.05.0-ce, build 89658be) and docker-compose (version 1.16.1, build 6d1ac21). One of this dockers contains an Apache which is restating in a loop.
Is there a way to fix this without losing dockers customizations?
I re-created all dockers with
docker-compose up --force-recreate
I didn't lose anything and everything is working now.
I recently reinstalled Redis on my Computer.After this my computer is not shutting down.It says "Waiting for Redis to shut down". Earlier redis used to restart with all updated key values when I switch on my computer, but it's continuously running now. How to resolve this?
use the command redis quit

Assuming that you are using Linux Or OSX you can use the command topin the terminal to find the PID
Once you've found this, type in kill followed by the PID
I am trying to get a simple, single instance of RabbitMQ running via this RabbitMQ-chef recipe. Essentially, I have an Ubuntu machine, and I’d like Chef to take care of all the heavy lifting necessary to install, configure and get RabbitMQ running on it.
The documentation isn’t really written for beginners, but I went ahead and started by downloading the cookook:
knife cookbook site download rabbitmq
WARNING: No knife configuration file found
Downloading rabbitmq from the cookbooks site at version 4.1.2 to /Users/myuser/sandbox/chef/0.6.2/rabbitmq-4.1.2.tar.gz
Cookbook saved: /Users/myuser/sandbox/chef/0.6.2/rabbitmq-4.1.2.tar.gz
However now I’m at a complete loss as to what I need to script/configure in order to add this cookbook to my Chef server, such that when I SSH onto my target Ubuntu machine, I can bootstrap that machine with Chef and then run something to turn the Ubuntu machine into a RabbitMQ server. Any ideas?
I've installed redis-server using apt-get install redis-server and everything went fine.
Right now I'm trying to configure it in a Cluster mode. The problem is that in the tutorial supplied here http://redis.io/topics/cluster-tutorial they use a script called redis-trib.rb which I can't find it in my system.
Can you please tell me how can I configure my Redis to run in Cluster mode without that script ?
I would like to have a setup with two masters, each on a different machine.
Thank you very much.
Had same problem with reredis-trib.rb
This tutorial explains how to create Redis Cluster using only Redis commands: Configuring and Running Redis Cluster on Linux
You need Redis 3.0.0 beta to run Cluster. You'll not find it in a Linux distribution, since they all have copy of the stable server (fortunately!). Redis 3.0.0 will go out as a stable release the next week. You can find the source code of the stable release here: http://redis.io/download.
There is now a tutorial for Ubuntu at https://www.digitalocean.com/community/tutorials/how-to-configure-a-redis-cluster-on-ubuntu-14-04 which includes installation of a PPA to supply 3.0.x. This tutorial is only for two nodes and does not reference redis-trib.rb ...
I would like to know what are the ways to automatically start daemons (sshd) in Fedora system. I know I can write a startup script that will put on /etc/init.d/.
What are the other options?
Somewhere I read that now in the new version of this can be done using the commands in the terminal, but I do not remember what it was.
EDIT: My 2 question.
I install ssh from source. When keys are generated for a server? During the installation?
You can do this via systemctl:
systemctl enable sshd.service
