Redis
Redis is fastest in-memory key-value store solution right now. It has been used for some caching mechanism so the app would work on a faster level and under the heavy load it could perform too.
Installation
You can do the installation in any folder you like but better to choose somewhere so you would be able to cleanup easier after installation. Enter the following commands one by one. they will get you through downloading latest source code and compiling:
1 2 3 4 5 6 7 | wget http://download.redis.io/redis-stable.tar.gz tar xvzf redis-stable.tar.gz cd redis-stable make sudo make install cd utils sh install_server.sh |
The last line will get you through a wizard like proccess that you can enter each one so default value will be used.
Security
If you want to you can set a password for redis in the wizard and the you will have to enter that password in configuration process but it's not necessary because Redis holds some trivial info that are not important and even accessing them wouldn't be security breach.
