I'm trying to connect to mysql workbench but I get the following error
Error Message Cannot Connect to Database Server
Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306: Could not open database.
Please: 1. Check that mysql is running on server 127.0.0.1
Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
Check the root has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines).
Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting.
i installed mysql server too in with workbench.help me
