and

Answer 1

One obvious guess would be that you didn't do FLUSH PRIVILEGES; after issuing GRANT statement.

Another obvious guess (not sure if typo in the question) is that syntax of GRANT is GRANT ALL PRIVILEGES ON mydb.* TO 'abc'@'%';, with ON in it.

Answer 2

You have created an user with allowing IP 10.10.131.17 and you are trying to connect MySQL Server from IP 10.10.10.7. So it won't work. To access MySQL Server you have to create user allowing IP 10.10.10.7 or allowing all IPs using %.

CREATE USER `abc`@`10.10.10.7` IDENTIFIED BY 'abc123' 
GRANT ALL PRIVILEGES mydb.* TO `abc`@`10.10.10.7`;

OR

CREATE USER `abc`@`%` IDENTIFIED BY 'abc123' 
GRANT ALL PRIVILEGES mydb.* TO `abc`@`%`;
