Quick local mysql access without password entry

Using mysql_config_editor which stores a ~/.mylogin.cnf file we can have easy access to mysql as a privileged user from the terminal without needing to enter your password nor needing to use sudo.

Step 1. Create the user

CREATE USER 'USERNAMEHERE'@'localhost' IDENTIFIED BY 'PASSWORDHERE';  

Step 2. Privileges, e.g. this would give you everything:

GRANT ALL PRIVILEGES ON *.* TO 'USERNAMEHERE'@'localhost' WITH GRANT OPTION;  
FLUSH PRIVILEGES  

Step 3. Use the config editor to generate your file.

mysql_config_editor set --user=USERNAMEHERE --password  
# it'll then ask for your password once

Step 4. Profit.

mysql  

^-- you should now be able to access your local mysql with a single command and no password entry needed.

You can also run mysql_config_editor with a --login-path=NAME flag to create multiple of these, then when starting mysql you can add that flag again to login to them.
