If you want to install redis on Linux machine but do not have an administrative access (root access) then you can follow this installation guide. This setup will work on all linux distributions like Ubuntu, Fedora, Red Hat, Debian, Raspbian etc. This will also work on Mac as it does not make use of packet managers for installation. If you are windows users then please check redis windows installation without admin access.

Installation Steps without Sudo

Download stable version of redis tarball from redis website.

(Current version is 4.0.11 and filename is redis-4.0.11.tar.gz)

https://redis.io/download

Create directory to install redis and extract content of downloaded tar ball into it.

mkdir /home/techmonger/redis/

Copy tar ball in above directory and extract it using following commands.

cp redis-4.0.11.tar.gz /home/techmonger/redis/
tar -xf redis-4.0.11.tar.gz

This will generate one more directory redis-4.0.11 inside your directory.

Navigate into generated directory and compile redis binaries using make.

cd /home/techmonger/redis/redis-4.0.11
make 

This will take some time to complete and it will create redis server binary (redis-server) and redis client binary (redis-cli) inside src directory of the current directory. (/home/techmonger/redis/redis-4.0.11/src/)

Navigate into src directory and start redis server with default configuration.

cd /home/techmonger/redis/redis-4.0.11/src/
./redis-server

This will start redis server on the default port 6379 with following standard output suggesting redis server has started.
