You have set a root password on your MySQL server. Use mysqladmin -p to allow it to prompt you for your password.

man mysqladmin

Guy thanks a lot but there are more problems..........

[root@Sam7 mysql-standard-4.1.0-alpha-pc-linux-i686]# mysqladmin --password 'helives'
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!

hahahah, hmmm are you sure that mysql is even running. If your running RedHat do the following:
service mysqld restart

If your running Slackware do this:

safe_mysqld &

If your running anything else, um install redhat or slack, ... hehhe kidding. Try the Slack problem resolve on any other system.

Problem #0: You are missing the '=' from your --password parameter.

Problem #1: MySQLd is not running. If the mysql.sock file doesn't exist, it means that the MySQL server is down.
try 'service mysql[d] start'

Your not required to put the = in the paramater.

mysqladmin -u root -p password 'newpassord'

works just fine.

Looks to me like he got the Password Entry. But the command I put in also works for changing the password or creating a new one. I do it daily.

Exactly! A program shouldn't prompt for a password if it was specified on the command line. Unless it was specified on the command line incorrectly, of course.

Also, the command for changing the password is
mysqladmin -u root --password=CURRENTPASSWORD password NEWPASSWORD

I have been struggling with these and related issues myself for the last few days.
I found password issue confusing too.

When you first start there is no root password, you must set it.
Until you set it, no password is required, and setting one causes trouble.
What I believe is that you need to put the -p switch on a command line if you want to be promted for the password.
There are other ways for the program to get a password, though.
If a password is set, and you do not add the -p switch, the command will fail unless the command finds the password by the alternate route.
You should avoid passing the password in the clear on the command line.

There are config files that client programs search in a fixed order from general to specific. The final, user level, file is named ~/.my.cnf.
You can put a password there, but you need to be careful about who can read the file. This is really only satisfactory for the root.
Some of the file might look like:

[mysqladmin]
password=secret
user=root

If you set up the root .my.cnf this way, then when root runs mysqladmin, it will not require the -p switch. This assumes that the password is up to date of course.

There are some helpul articles, one of which is:
Getting Started with MySQL

In the end, I fear I will have to read most of the MySQL manual, which is on their website, and which is generally good.

I think a lot of my problems are about things which have become "obvious" to experienced MySQL users.

My goal was to learn whether I should make a long term commitment to using MySQL. There are obvious advantages, but there are risks too. Right now I am struggling with ODBC, but I think I will start a new thread for help with this.
