The error message 'failed to start redis service unit redis service not found' indicates that the Redis service is not installed or is not running on the system. The error may occur due to various reasons, such as an incorrect installation process, outdated packages, or misconfiguration of the Redis service.
Redis is a popular in-memory key-value store, and it requires proper installation and configuration for its smooth functioning. If the Redis service is not properly installed, the system will not recognize it, leading to the above error message.
To resolve the 'failed to start redis service unit redis service not found' error, you need to ensure the Redis service is installed and configured properly. You can try the following solutions:
Check if Redis is installed: Use the command "redis-cli ping" to verify if Redis is installed on your system. If the Redis server responds with pong, then Redis is installed correctly. If it returns an error, then Redis is either not installed or not properly installed.
Install Redis: If Redis is not installed, you can install it using package managers like apt or yum depending on your OS. For example, on Ubuntu, you can run the command "sudo apt-get update && sudo apt-get install redis-server", and on CentOS, you can use "sudo yum install redis".
Restart Redis service: If Redis is already installed, you can try restarting the service using the command "sudo service redis restart". This command stops and starts the Redis service.
Check Redis configuration file: If the Redis service is still not starting, check the Redis configuration file (/etc/redis/redis.conf) for any misconfigurations. Ensure that the bind and port settings are correctly set.
By following these steps, you should be able to resolve the 'failed to start redis service unit redis service not found' error and have Redis running smoothly on your system.
