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 ...

We want to build test Hadoop cluster on one Linux machine based on docker container/s
Dose hortonworks ( cloudera ) support this ? ,
For example HDP version - 2.6.5
For example we need the following services
HDFS ( include at least 3 data-nodes , )
YARN
MAPreduce2
HIVE
Zookeeper
Ambari metrics
KAFKA
SPARK2
and all these services should be on one Linux machine
#Jessica it is not possible to do a 3 node (hdfs) instance with a single node machine. Other than that, a single node cluster can run all of the services you have listed and is suitable for learning, training, and demos or proof of concepts.
I am running Docker with Linux containers. When I try to do a Redis pull I get "docker: no matching manifest for windows/amd64 in the manifest list entries." I have seen many tutorials showing redis running on docker windows. Has something changed with later versions of redis which means that it no longer works with docker on Windows?
start dockerd.exe with the --experimental flag and your problem will be solved.

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.
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 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?
