Doc issue : localhost is not 127.0.0.1

[Korsani]

CREATE USER 'exporter'@'localhost' IDENTIFIED BY 'XXXXXXXX' WITH MAX_USER_CONNECTIONS 3;
GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'localhost';

Won't work with --mysqld.address defaulted as localhost:3306 as --mysqld.address will try to connect to 127.0.0.1, which is the address for localhost, but for mysqld localhost, in CREATE USER and GRANT is the unix socket.

So :

CREATE USER 'exporter'@'127.0.0.1' IDENTIFIED BY 'XXXXXXXX' WITH MAX_USER_CONNECTIONS 3;
GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'127.0.0.1';

works better.
