Redis is an open-source, in-memory key-value data store. You can install Redis on Ubuntu Linux by following these steps:
- Update the package lists and upgrade the system using the following command:
sudo apt-get update
sudo apt-get upgrade
- Install the Redis server package by running the following command:
sudo apt-get install redis-server
- Once the installation is complete, you can check the Redis server status by running the following command:
systemctl status redis-server
- To configure Redis server, you can edit the configuration file located at /etc/redis/redis.conf, this file contains various options which you can configure as per your requirement, like memory allocation, network settings, and security.
- Once you are done with the configuration, you can restart the Redis server using the following command:
sudo systemctl restart redis-server
- To check if Redis is working fine, you can use the redis-cli tool, to connect to the server and issue some command to test it.
redis-cli ping
If the Redis server is running and configured properly, the above command will return “PONG”
It is important to note that by default Redis is not configured for production use, you should check the security settings and tweak them as per your requirement before using it in a production environment.
Additionally, you can also install Redis via package manager like apt, apt-get or aptitude. The process is similar, but the command may vary.
