The error "cannot connect to Redis-server VMware Ubuntu" typically indicates an issue with the connection between your application and the Redis server running on a virtual machine within VMware on an Ubuntu host. There are several possible causes for this problem: 1) The Redis server may not be running or might have crashed; 2) Network configuration issues, such as incorrect IP address, hostname, or port settings in either the Redis server or your client application; 3) Firewall restrictions preventing proper communication between the application and the Redis server; 4) Misconfiguration in the Redis configuration file (redis.conf).
To resolve the connection issue, follow these steps:
redis-cli pingfrom the command line. If you receive a "PONG" response, it confirms the server is running. If not, restart the Redis server using
sudo service redis-server startor the appropriate command depending on your system configuration.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
