This is actually a redis connection error, not a database connection error, the database connection error is this: jdbc connection refused
There are many specific reasons, such as: wrong ip, port not open, ip cannot be pinged and not allowed to access, etc.
I am here because the server ip cannot be pinged, it can be solved by releasing it in the security group.
