I have installed Mysq 5.0.67l on a Linux FEdora 10 box, and all is working well except one thing.  I should be able to login without specifying any password as long as I am logged into the Linux box as "root" and, in fact, it was this way when I first got the install up and running.  I have imported many databases (via mysqldump) from other systems, and now I can no longer log in without a password when logged in as "root".

Two ways...

Don't define the root password for MySQL


         To use SET PASSWORD on Unix,
do         this:        shell> mysql -u root
mysql> SET PASSWORD FOR ''@'localhost' = PASSWORD('newpwd');
mysql> SET PASSWORD FOR ''@'host_name' = PASSWORD('newpwd');

With newpwd net defined, no spaces or anything.

See this for more: http://dev.mysql.com/doc/refman/4.1/en/default-privileges.html


Or

create a .my.cnf file in your home (root) directory and put these line in it:

[client]
user=root
password=thepassword

You can login to mysql via command line by typing mysql.  

So that only root can read this file chmod it to 600:
chmod 600 .my.cnf
