Create MySQL users has changed

After all this time, the way of creating users and granting privileges on user in one statement just doesn’t work anymore. I guess I just missed the memo

New-MacBook-Pro:robl cex$ mysql -u root
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 9

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> GRANT ALL ON robl.* to robl@localhost IDENTIFIED BY 'robl';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL 

Ok, so we need to create the user and then do the grant

mysql> CREATE USER robl IDENTIFIED BY 'robl';
Query OK, 0 rows affected (0.01 sec)

mysql> GRANT ALL ON robl.* TO robl@localhost;
ERROR 1410 (42000): You are not allowed to create a user with GRANT
mysql> CREATE USER robl@localhost;
Query OK, 0 rows affected (0.00 sec)
mysql> CREATE USER robl@localhost iDENTIFIED BY 'robl';
ERROR 1396 (HY000): Operation CREATE USER failed for 'robl'@'localhost'
mysql> DROP USER robl;
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE USER robl@localhost IDENTIFIED BY 'robl';
ERROR 1396 (HY000): Operation CREATE USER failed for 'robl'@'localhost'
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE USER robl@localhost IDENTIFIED BY 'robl';
ERROR 1396 (HY000): Operation CREATE USER failed for 'robl'@'localhost'
mysql> DROP USER robl;
ERROR 1396 (HY000): Operation DROP USER failed for 'robl'@'%'

Ok, let’s just start again.

mysql> DROP USER robl@localhost;
Query OK, 0 rows affected (0.01 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE USER robl@localhost IDENTIFIED BY 'robl';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL ON robl.* TO robl@localhost;
Query OK, 0 rows affected (0.00 sec)

mysql> 

Ok, now I can get this started.
