Installing Redis 4 (latest stable version) on windows - windows

How can I install Redis latest stable version (4.0) on Windows?
I checked MSOpenTech's GitHub page it has an older version and archived.

If you are interested in native version of Redis for Windows - please check the updated fork of the mentioned MSOpenTech's repository here: https://github.com/tporadowski/redis/releases
This is a merge of latest 3.2.100 from MSOpenTech/redis and original Redis 4.0.2. Please read the details of what is and what is not supported at the moment and note that this is still in "alpha" state.

Use Docker for Windows. Then install redis the normal way.
docker run --name some-redis -p 6379 -d redis

bind source path does not exist: /host_mnt

I have a ddev installation on macOS which I used for a while.
ddev 1.16.2
docker 20.10.0
macOS 11.0.1 - Intel
Today I upgraded to docker 20.10.0 and in the process to ddev 1.16.2.
When I start an existing site, that worked all the time I get
Creating ddev-mysite-db ... error
ERROR: for ddev-mysite-db Cannot create container for service db: invalid mount config for type "bind": bind source path does not exist: /host_mnt/Users/me/Documents/Development/WebSite/mysite/.ddev
This started to happen after I upgraded docker from the previous version. Upgrading ddev did not change too much.
Even when I create a new site, the same error message pops up so I am pretty much stuck.
At least for me it looks like the docker 20.10.0 breaks ddev. Any ideas how to deal with that are very much appreciated.
Docker/macOS are not allowing access to the directory ~/Documents.
Starting with macOS Catalina, ~/Documents is a "protected directory", so you have to allow docker access to it, and docker should prompt.
However, Docker Desktop for Mac's 3.0.0 release (which I imagine you're referring to) had a bug where it did not do this properly. I imagine you need to upgrade to version 3.0.1 which was released today. Just "Check for updates"
In Docker > Preferences > Experimental features you can try disabling gRPC, and make Docker use osxfs file sharing system.

How to install Redis on Windows 10 pc [duplicate]

How do I run Redis on Windows? The Redis download page just seems to offer *nix options.
Can I run Redis natively on Windows?
Historically, Microsoft had a Windows port of redis, which was released as Redis-64, which offers a full distribution of redis for Windows.
The Microsoft port is now deprecated, but some alternatives have sprung up to fill that void:
Memurai is the alternative officially recommended on the Redis-64 deprecation page; it is a commercial offering with free developer tier, maintained by Janea Systems
redis-windows is another unofficial port, which also exists
This release includes the redis-server.exe (memurai.exe on Memurai) application that runs a Redis instance as a service on your windows machine, as well as redis-cli.exe (memurai-cli.exe on Memurai) which you can use to interact with any Redis instance.
The RGL repository has historically been listed as an alternative Windows port for Redis, but this repository has not been maintained for some time and implements an older version of Redis than the Microsoft port.
Update
If you have Windows Subsystem for Linux (WSL), natively on Windows 10 and Windows Server 2019 you can do it per
Ogglas answer
Or follow these instructions to run a Redis database on Microsoft Windows
Turn on Windows Subsystem for Linux
In Windows 10, Microsoft replaced Command Prompt with PowerShell as the default shell. Open PowerShell as Administrator and run this command to enable Windows Subsystem for Linux (WSL):
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Reboot Windows after making the change — note that you only need to do this once.
Launch Microsoft Windows Store
start ms-windows-store:
Then search for Ubuntu, or your preferred distribution of Linux, and download the latest version.
Install Redis server
Installing Redis is simple and straightforward. The following example works with Ubuntu (you'll need to wait for initialization and create a login upon first use):
sudo apt-add-repository ppa:redislabs/redis
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install redis-server
Please note that the sudo command might or mightn't be required based on the user configuration of your system.
Restart the Redis server
Restart the Redis server as follows:
sudo service redis-server restart
Verify if your Redis server is running
Use the redis-cli command to test connectivity to the Redis database.
$ redis-cli
127.0.0.1:6379> set user:1 "Ben"
127.0.0.1:6379> get user:1
"Ben"
Please note: By default, Redis has 0-15 indexes for databases, you can change that number of databases NUMBER in redis.conf.
Stop the Redis Server
sudo service redis-server stop
Source :How to Install Redis on Windows
I found one more simple way to install Redis under Windows
Download the latest Redis .msi file from
https://github.com/MSOpenTech/redis/releases
after installation. The Redis service is installed, and we can operate it from Service manager
If you want to install MSOpenTech's latest port of Redis, on a Windows server, watched over by a Windows Service, without having to build anything yourself, read on.
MSOpenTech's seems to be the only port that is actively trying to keep up with the latest and greatest Redis. They claim it is production-ready, but they haven't exactly packaged it up neatly for installation on a server, especially if you want to run their RedisWatcher service to keep an eye on it, which is recommended. (I tried building RedisWatcher myself per their instructions, but the required Wix Toolset managed to mess up my system pretty good. I won't go into it.) Fortunately they've provided all the binaries you need, just not all in one place. From the README:
So far the RedisWatcher is not carried over to 2.6. However this
should not be affected by the Redis version, and the code in the 2.4
branch should work with the Redis 2.6 binaries.
So you'll need to download binaries from 2 branches in order to get all the necessary bits. Without further ado, here are the steps:
Download and extract the Redis binaries from the 2.6 branch
Copy all extracted binaries to c:\redis\bin
Create another folder at c:\redis\inst1
Download and extract the RedisWatcher binaries from the 2.4 branch
Run InstallWatcher.msi. This should create a Windows service called Redis watcher.
Open up the Windows Services console and start the Redis watcher service.
(optional) RedisWatcher should have installed to C:\Program Files (x86)\RedisWatcher. There you'll find a config file called watcher.conf, which you can edit to set up additional instances, use different paths than I specified in steps 2 & 3, etc. You will not need to restart the service for changes to take effect.
The most updated (only few minor releases behind) version of Redis can be found here. This repository provides you with 3.2.100 version (current is 3.2) whereas the most upvoted answer gives you only 2.4.6 version and the last update to the repo was 2 years ago.
The installation is straightforward: just copy everything from the archive to any folder and run redis-server.exe to run the server and redis-cli.exe to connect to this server through the shell.
To install Redis for Windows
You can choose either from these sources
https://github.com/MSOpenTech/redis/releases
or
https://github.com/rgl/redis/downloads
Personally I preferred the first option
Download Redis-x64-2.8.2104.zip
Extract the zip to prepared directory
run redis-server.exe or redis-server.exe --maxheap 2gb
then run redis-cli.exe
You can start using Redis now, please refer for commands
Maybe its a little Late but, I was able to run Redis on Windows 10 Aniversary Update.
Windows 10 Aniversary Update Comes with Bash on Ubuntu on Windows, simply, it comes with bash.
Below are the two tutorial that I followed:
1- How to Install and Use the Linux Bash Shell on Windows 10
2- How To Install and Use Redis
Below is the image of running Redis.
Enjoy :)
If you have Windows Subsystem for Linux (WSL), natively on Windows 10 and Windows Server 2019 you can do it like this:
Set up WSL:
To enable Windows Subsystem for Linux, follow the instructions on
Microsoft Docs. The short version is: In Windows 10, Microsoft
replaces Command Prompt with PowerShell as the default shell. Open
PowerShell as Administrator and run this command to enable Windows
Subsystem for Linux (WSL):
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Reboot Windows after making the change—note that you only need to do this one time.
Download and install one of the supported Linux distros from the Microsoft Store. Ubuntu works fine.
Note that Ubuntu 20.04 LTS may give you some trouble because of a known issue with the realtime clock (as of August 2020). Choosing Ubuntu 18.04 LTS instead avoids that issue.
Install and Test Redis:
Launch the installed distro from your Windows Store and then install redis-server. The following example works with Ubuntu (you’ll need to wait for initialization and create a login upon first use):
> sudo apt-get update
> sudo apt-get upgrade
> sudo apt-get install redis-server
> redis-cli -v
Restart the Redis server to make sure it is running:
> sudo service redis-server restart
Execute a simple Redis command to verify your Redis server is
running and available:
$ redis-cli
127.0.0.1:6379> set user:1 "Oscar"
127.0.0.1:6379> get user:1
"Oscar"
To stop your Redis server:
> sudo service redis-server stop

https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux
Go to the releases and you can get a ZIP file containing the relevant files as well as a Word document called RedisService.docx with the following instructions:
Installing the Service
--service-install
This must be the first argument on the redis-server command line. Arguments after this are passed in the order they occur to Redis when the service is launched. The service will be configured as Autostart and will be launched as "NT AUTHORITY\NetworkService". Upon successful installation a success message will be displayed and Redis will exit.
This command does not start the service.
For instance:
redis-server --service-install redis.windows.conf --loglevel verbose
And then later, in the same document, another example:
The following would install and start three separate instances of Redis as a service:
redis-server --service-install -–service-name redisService1 –port 10001
redis-server --service-start --service-name redisService1
redis-server --service-install --service-name redisService2 –port 10002
redis-server --service-start --service-name redisService2
redis-server --service-install --service-name redisService3 –port 10003
redis-server --service-start --service-name redisService3
From what I can gather, this appears to be the new way forward rather than messing with a separate Windows service to monitor and restart the CLI.
Download redis from
Download Redis for windows
Then install it
open cmd with admin rights
run command net start redis
Thats it.
MS Open Tech recently made a version of Redis available for download on Github. They say that it isn't production ready yet, but keep an eye on it.

You can use Memurai for Windows, a Redis-compatible cache and datastore for Windows, currently compatible with Redis 5. Memurai aims to fulfill the need for a supported Redis-compatible datastore on the Windows platform. At its core, it’s based on Redis source code, ported to run natively on Windows, and it’s designed to provide the level of reliability and performance required for production environments. Memurai is free for development and testing. You can learn more and download Memurai at https://www.memurai.com.

There are two ways. You can use MSI installation file or do it manually:
First download the msi or the zip file:
You can download both files from here:
https://github.com/MicrosoftArchive/redis/releases
Watch video tutorial (video covers example of both installations)
See this installation video tutorial: https://www.youtube.com/watch?v=ncFhlv-gBXQ
Instruction - for those who can not YT at work:
You can download a moderately out-of-date precompiled version of Redis for 32-bit
and 64-bit Windows thanks to Dusan Majkic from his GitHub page: https://github.com/dmajkic/redis/downloads. Go ahead and do that now.
After you download Redis, you’ll need to extract the executables from the zip file.
As long as you’re using a version of Windows more recent than Windows XP, you
should be able to extract Redis without any additional software. Do that now.
After you’ve extracted either the 32- or 64-bit version of Redis to a location of your
choice (depending on your platform and preferences; remember that 64-bit Windows
can run 32- or 64-bit Redis, but 32-bit Windows can only run 32-bit Redis), you can
start Redis by double-clicking on the redis-server executable. After Redis has
started, you should see a window similar to figure A.1.

Since MSOpenTech's port of Redis is no longer maintained - anyone interested in native port of Redis for Windows can now get the version 4.0.14 and 5.0.10 from here: https://github.com/tporadowski/redis/releases.
This fork is a merge of latest 3.2.100 version from MSOpenTech and 4.0.14/5.0.10 from antirez/redis with a couple of bugfixes.
I don't run redis on windows. There's too much hassle involved in keeping up with the ports, and they lag behind redis-stable by a version or two all the time.
Instead I run redis on a Vagrant virtual machine that runs redis for me. I've bundled up the whole thing into a simple github repo so everyone can get in on the fun without too much hassle. The whole thing is an automated build so there's no mess. I blogged about the details here.
To install Redis on Windows system follow the below steps:
Visit one of the below link:
https://github.com/MSOpenTech/redis/releases (recommended)
https://github.com/rgl/redis/downloads
Download MSI file.
Follow the installation Wizard and install the program on your system. (do not change the installation path that is "C:\Program Files\Redis")
Search for "Edit system environment variable" on your start menu
Click on "Environment Variable" button
Select "Path" and click on "Edit"
Now click on "New"
Paste C:\Program Files\Redis (or the path in case you have changed while installing)
Click on "Okay", "Okay" and "Okay"
Now open your Terminal (command prompt) and run redis-cli
Well I am getting some error to open redis-server (It was working fine till now but not sure what's wrong so figuring out and will update this answer)
I think these is the two most simple ways to run Redis on Windows
1 - Native (and updated) port for Windows
As described here on Option 3) Running Microsoft's native port of Redis:
Download the redis-latest.zip native 64bit Windows port of redis
wget https://github.com/ServiceStack/redis-windows/raw/master/downloads/redis-latest.zip
Extract redis64-latest.zip in any folder, e.g. in c:\redis
Run the redis-server.exe using the local configuration
cd c:\redis
redis-server.exe redis.conf
Run redis-cli.exe to connect to your redis instance
cd c:\redis
redis-cli.exe
2 - With Vagrant
You can use Redis on Windows with Vagrant, as described here:
Install Vagrant on Windows
Download the vagrant-redis.zip vagrant configuration
wget https://raw.github.com/ServiceStack/redis-windows/master/downloads/vagrant-redis.zip
Extract vagrant-redis.zip in any folder, e.g. in c:\vagrant-redis
Launch the Virtual Box VM with vagrant up:
cd c:\vagrant-redis
vagrant up
This will launch a new Ubuntu VM instance inside Virtual Box that will
automatically install and start the latest stable version of redis.
If you're happy with a bit of Powershell, you can also get very up-to-date Windows binaries using Powershell and chocolatey.
First, add chocolatey to Powershell following the instructions here (one simple command line as admin): https://chocolatey.org/
#powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
Then, use Powershell to get the redis package from chocolatey: http://chocolatey.org/packages/redis-64
choco install redis-64
Redis will be installed in something like C:\ProgramData\chocolatey\lib\redis-64.2.8.9
Windows PowerShell Copyright (C) 2013 Microsoft Corporation. All

Then run the server with
redis-server
Or the CLI with
redis-cli
Follow the instructions in C:\ProgramData\chocolatey\lib\redis-64.2.8.9\RedisService.docx to install the redis service
The Redis download page now has links to some unofficial Windows ports. The dmajkic one seems to be the most popular/complete.

One of the most easy way to run Redis on windows host is to use Docker Redis container. Just fire up Hyper-V, Download Docker and run Redis
I am using Memurai which is Redis-compatible cache and datastore for Windows. It is also recommended by Microsoft open tech as it written on their former project here.
This project is no longer being actively maintained. If you are
looking for a Windows version of Redis, you may want to check out
Memurai. Please note that Microsoft is not officially endorsing this
product in any way.
you can install Redis by following this article:
https://github.com/ServiceStack/redis-windows
but for going straight, you can download it by this link:
https://github.com/ServiceStack/redis-windows/raw/master/downloads/redis-latest.zip
after downloading, go to the directory which you like to put your files,then extract the zip file, then open a command prompt and go to the directory where you extracted your file, then type "redis-server" and hit enter(for opening redis-cli open command and route to redis directory, but instead of "redis-server" execute "redis-cli").
I've provided installation instructions and downloads for the 2 most popular ways of running Redis on windows at: https://github.com/mythz/redis-windows that shows how to:
Use Vagrant to run the latest stable version of Redis inside a
VirtualBox VM.
Download and run Microsoft's Native Windows port of Redis
Using Windows 10?

apt install redis-server
Today I know these 4 options:
The first is an open source fork that is on tporadowski/redis that offers compatibility with version 5 (version 6 in development).
The second is memurai (paid), compatible with version 5, has support and a free version for development.
The third is the zkteco-home/redis-windows recently, which offers compatibility with version 7, but is not open source.
There is also the option to run via WSL. But I don't recommend it in production environments.
You can try out baboonstack, which includes redis and also a node.js and mongoDB version manager. And it's cross platform.
The redis version on windows was published by microsoft open tech team But recently this project has been archived to https://github.com/MicrosoftArchive/redis read-only and will not update. Has stopped development
Here are my steps to install Redis 4.0.8 on Windows 10 Pro (1709) via Windows Subsystem for Linux:
in home/user/
01 wget http://download.redis.io/releases/redis-4.0.8.tar.gz
02 tar xzf redis-4.0.8.tar.gz
03 cd redis-4.0.8/
04 sudo apt-get install make
05 sudo apt-get update
06 sudo apt-get install gcc
07 cd deps
08 make hiredis jemalloc linenoise lua geohash-int
09 cd ..
10 make
You can skip several steps if you have an up-to-date environment.

Reading about some users running Redis in a VM, it brought to my mind the recommendations from Redis team :
Redis runs slower on a VM. Virtualization toll is quite high because for many common operations. (...) Prefer to run Redis on a physical box, especially if you favor deterministic latencies. On a state-of-the-art hypervisor (VMWare), result of redis-benchmark on a VM through the physical network is almost divided by 2 compared to the physical machine, with some significant CPU time spent in system and interruptions.

ICP 3.1.0 Vagrant support

*I used * [1]: https://github.com/IBM/deploy-ibm-cloud-private/blob/master/docs/deploy-vagrant.md
to install ICP 2.1.0.3 on my mac.
Does it support also ICP 3.1.0?
As of right now, I believe this tool cannot be used to install ICP 3.1.0 because the relevant icp-inception image has not been added to Docker Hub. When that image is available, the tool might work if you change the version parameter on line 22 in the Vagrantfile.
Even with the correct image, there may be other configuration steps that need to be taken such as changing the k8s_version or the memory requirements, since these have changed in 3.1.0.
EDIT: The image is now available on Docker Hub, but I have not tested configuring the vagrantfile to install 3.1.0 yet.
I used it successfully to install ICP 3.1 on my Linux PC. I just had to set
version = "3.1.0"
in the Vagrantfile.

Elastic Beanstalk & Docker - EB CLI Does Not Work on Mac! BUG

Docker version 17.09.0-ce, build afdb6d4
I thought the above seemed understandable enough, at first. I have version 17.09.0-ce of Docker, but I need version 17.03.2-ce. It would seem reasonable that AWS would be a few versions behind the latest version of Docker if nothing else than to double check system integration and security.
However, when it came time to find version 17.03.2-ce I found it almost impossible. https://github.com/moby/moby/releases points me to 17.03.02-ce as a direct link on the downloads page, which again downloads the wrong version. I tried downloading the link to the static binaries, however that was very confusing. This page https://docs.docker.com/engine/installation/linux/docker-ce/binaries/#next-steps says that in order to get the static binaries to compile I should run the command sudo cp docker/docker /usr/local/bin/, however nowhere in that static binary folder is there a folder labeled docker.
Meanwhile this page https://docs.docker.com/docker-for-mac/release-notes/#docker-community-edition-17090-ce-mac32-2017-10-02-stable, goes from release Docker Community Edition 17.03.1-ce-mac12, 2017-05-12 (stable) to release Docker Community Edition 17.06.0-ce-mac18, 2017-06-28 (stable). Not only does this skip the one release I need, but it seems to have versions that are ahead of the most recent release at https://github.com/moby/moby/releases.
I'm very very confused. It should not be as difficult as this to get the currently stable version of Docker that runs with AWS. Can someone let me know how to resolve this issue?
EDIT:
I spun up my Linux Mint 18 (Ubuntu 16.04) and installed docker to try and get this to work. As it happens linux ALSO installs version Docker version 17.09.0-ce, however this one works with the 1) Docker 17.03.2-ce elastic beanstalk option. All the same commands on a linux environment running the same version of docker now run on eb cli. Therefore I am retitling this post as an EB CLI bug for mac. My question now is, where do I submit a bug report to AWS? I have searched for a github repository for them, but have not found it, and I think that most of their reporting through aws.amazon.com is for enterprise level customers.
Thanks!

lxc-attach failed to enter the namespace - EC2 Instances

For some reason I cannot enter a docker container using Lxc-attach only on EC2 instances. This works on my local machine and on Digital Ocean (KVM) droplets but not on Amazon EC2 xen-paravirtualized Ubuntu12.04 instance. Here are the steps/errors:
root#ip-172-31-46-202:~/scalar/project/docker# lxc-ls
4074ebf985cfe09b2880a9eabbc7ad3e59283f425f64cfaa72f59f1f23661d18

lxc-attach: No such file or directory - failed to open '/proc/19731/ns/pid'
lxc-attach: failed to enter the namespace
Does anyone know if there is a way to resolve this issue? Here are my docker version details:
Client version: 0.7.6
Go version (client): go1.2
Git commit (client): bc3b2ec
Server version: 0.7.6
Git commit (server): bc3b2ec
Go version (server): go1.2
Last stable version: 0.7.6
Also:
lxc version: 0.7.5
What is your kernel version?
lxc-attach requires features that are not present in the native 12.04 kernel (3.5). You need at least 3.8 which IIRC is available in the backport.
As Creac suggested, the kernel was not of a high enough version. (and if I try re-deploying an AWS ubuntu image it still uses kernel 3.2)
To fix this issue, I ran the following command to get 3.8:
sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring
or you can run the following command to get 3.5
sudo apt-get install linux-image-generic-lts-quantal linux-headers-generic-lts-quantal
Please note that these commands are Ubuntu specific (as per the question) and will install the "generic" kernel rather than the "virtual" kernel, but should work. [source]
Note that I tried to update Creac's original answer with this additional information but the edit was rejected so I felt the need to create a new answer for others to use if they want.
