this my error :
MySQL root user name or password is incorrect in /root/.my.cnf, please double check

in my files /root/.my.cnf there is :

[client]
host = localhost   (i'm testing with 127.0.0.1 ......!!!)
port = 3306
user = root
password = password

or

[client]
host = "localhost"  (i'm testing with 127.0.0.1 !!!!!!!!!!!!!!)
port = "3306"
user = "root"
password = "password"

it's the same error !!!

the password of root is Ok, I log into service mysql with the commande  mysql -u root -p   ----> this OK with the good password
