Hello everyone

I have read every thread i could find and tried every command i can, i am sure i am doing something wrong or lack of sleep has fried my brain.

brand new 5.0.45 MySQl install, i need to allow access on root from all hosts with no password

i cant get it to work, i can only connect from local host on root...

i tried adding *.* as a host using mysql admin but it seems to do nothing and doesnt allow me to connect from another system

i have tried grant commands, giving grant to root,flush privileges afterwards, but nothing is working for me, this is a test bed system, not accessible from the Inet, i am redoing someone else's work who has no security so for now i need just root access with no password from *.* anywhere.....

Please save what little sannity i have left, i know the question has been asked, but i have tried literally ever response people have given to everyone else :(

well, let me tell you ROOT with no password for any host is like serving it on the golden plate to hackers...
DON'T do that... it will save you from more severe illness later!!!

why ROOT?
why no password?

First of all, like Angellll says: root with NO password is ...I even do not have an idea how to call such approach!

But if you still want to grant access to all hosts, put "%" instead of "localhost" in Host row of mysql table, and reload privileges.

I know it is, why this system isnt accessible to the internet right now, i am well aware of the security issued involved.

the original coder claimed passwords didnt work with his scripts, i have tested some, and some work and some dont, this person also uses global variables (using php with mysql).

So i am just trying to move what i need to a new server, once done, i plan to go back over the coding and fix it so it works with user and passwords, these items wont be seeing the light of day, or the internet, until they are password protected.

...also, assure firewall is not blocking traffic on port 3306, which is used by MySQL server.

actually, with PHP, having no password will not work, you will have to use a password anyhow.

not sure, cause non of his php scripts have password to connect to the mysql DB's and his pages work, not a single one! scary how he got by for 4 years doing this, using root with no passwords to connect tot he DB's, not even IP access was used.


example


$use=$PHP_AUTH_USER;
      $dblink=mysql_connect("**********", "root", "");
      $db_list = mysql_list_dbs($dblink);
            while ($database=mysql_fetch_object($db_list))


all his scripts are like that.

angelIII, could i tbe because of using version of PHP 4 and lower? i know after 4.1? global variables was off by default and other security items changed to make it more out of the gate secure.

It is:
GRANT ALL ON *.* TO 'root'@'%';
FLUSH PRIVILEGES;
or
REVOKE ALL ON *.* TO 'root'@'%';
FLUSH PRIVILEGES;

i am still getting the error

Can't find any matching row in the user table

running the GRANT ALL ON *.* TO 'root'@'%';

i am conencting using mySQL Query Browser and then connecting to the mysql folder locally on the machine which the BD is hosted on... am i doing something incorrectly? or is their some restriction on mysql 5.0.45 that wont allow me to grant this access to root?

yes, that is highly probable!

now, please run this:

mysql> use mysql
mysql> select user, hostname, password from user

and report that it returns (clearing the passwords anyhow).

is it posible i may need to put a password on root before i can allow external access, and if so, can i remove the password after it was been added?

Well, it seems to make this work, this method worked


Put a password on the root account / Apply
Add Hosts from which the user can connect   (*.*)
remove password from root account / apply


done, can now access externally from any host, i did this using MySQL Admin.

The solution was correct, but did not seem to apply perfectly to this situation, perhaps this is a new limitation in MySQL 5.0.45 + that you can not give such access with out root having at least a password to start, which is good news of course.

I am glad you solved it. MySQL admin tool can be used for such things, too.
