Configuration Publishers - Subscribers

The Configuration Pub-Sub concept is a simple server that listens for configuration updates and publishes them to a Redis server. This allows other services using the same Redis server to receive the latest configuration updates seamlessly.

Install Redis

To install Redis, follow these steps:

1. Download the latest version of Redis from here.

   wget https://download.redis.io/redis-stable.tar.gz

2. Compile and install Redis:

   mkdir $HOME/redis/
   cp redis-stable.tar.gz $HOME/redis/
   cd $HOME/redis/
   tar xvzf redis-stable.tar.gz
   cd redis-stable
   make

3. (Optional) Add Redis to the PATH:

   echo "alias redis-server='$HOME/redis/redis-stable/src/redis-server'" >> $HOME/.bashrc
   source $HOME/.bashrc
