This is a stable release, for beta testing make sure to download the latest source code from Git:
git clone git://github.com/antirez/redis.git
It's also possibe to download the latest source code as a tarball:

To compile Redis, do the following:
cd src; make
The compilation will produce a redis-server binary.
Copy this file where you want.
Run the server using the following command line:
/path/to/redis-server
This will start a Redis server with the default configuration.
Otherwise if you want to provide your configuration use:
/path/to/redis-server /path/to/redis.conf
You can find an example redis.conf file in the root directory
of this source distribution.
