Redis is often referred to as a data structures server. This means that Redis provides access to mutable data structures via a set of commands, which are sent by using a client/server model with TCP sockets. Different processes can query and modify the same data structures in a shared way. (from the official git repo)
First, your Linux server must be equipped with git. To install git, use the following command.
apt-get update; apt-get install -y git
yum update; yum install git
After the installation of the git, download the source code of Redis.
git clone http://github.com/antirez/redis/
Before compiling the source code, you should have the
build-essential package installed.
apt-get install build-essential
yum groupinstall "Development Tools"
Once this package is installed, make and install Redis.
sudo make; sudo make install
Congrats, you now have the Redis server installed! You can type
redis-cli to query/insert data or type
redis-benchmark to test out the performance of your VPS.
