MySQL root user password

Hi all

I think that the installation of MySQL on a server usually includes setting the the MySQL root user password. My new Debian 6 VPS comes with MySQL pre-installed so does that mean that the MySQL root user password has already been set? If so where do I find it? I know there are SSH commands for setting and re-setting the MySQL root user password but of course these instructions are different according to whether I am creating a password for the first time or resetting an existing password.

Thanks

Hi Juc,

This depends on whether or not you've got a control panel such as Plesk or cPanel, I believe both will set the MySQL root password accordingly (Plesk for sure). But on a vanilla VPS the password is not set at all by default.

Yes it is Parallels Plesk Panel 10.4.4 - but if the MySQL root password has already been set, where can I find it?

Thanks

Plesk apparently renames the root user for mysql to admin and sets the password but you can use Plesk commands to retrieve it :)

# /usr/local/psa/bin/admin --show-password

yes that works to get the password, thanks, but then if I use

Code:

---

mysql -uUSERNAME -pPASSWORD

---

=

Code:

---

mysql -uadmin -pmypastedpassword

---

I get

Code:

---

ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)

---

Does that make sense?

Thanks

In Plesk by default mysql root is changed to admin. It's supposed to sync passwords with your admin password, but life is never that simple. Try:

Code:

---

mysql -uadmin -p `cat /etc/psa/.psa.shadow`

---

I have tried two passwords - the one output by this...

Code:

---

# /usr/local/psa/bin/admin --show-password

---

...and the one that is my plesk login password but neither works and both give

Code:

---

ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)

---

Any suggestions please?

Thanks

Please consult customer support before applying this following solution, it may cause Plesk failed to load.

If this following command failed

Code:

---

mysql -uadmin -p `cat /etc/psa/.psa.shadow`

---

You should try this following solution:
1.Load MySQL with the 'skip-grant-tables' option by adding skip-grant-tables into [mysqld] section of the /etc/my.cnf file
2.Restart MySQL with the command line below:

Code:

---

# /etc/init.d/mysqld restart

---

3.Repair password with the command line below:

Code:

---

# /usr/bin/mysql -D mysql -e"update user set password=PASSWORD('`cat /etc/psa/.psa.shadow`') where User='admin';"

---

4.Remove skip-grant-tables option from /etc/my.cnf
5.Restart MySQL.

If the solution above still not working, I recommend that you contact Customer Support.

Hi Juc,

Sometimes if there are special characters in passwords, pasting into the command line login command isn't the best approach. I've found more luck by typing "mysql -u username -p". When you do this, it will prompt you for the password. You can then past or type it in manually there and you shouldn't have character problems. :)

Also, unless you want to toy with fire and break Plesk' connection to the database, i would be very careful with the previous recommendations by Suwunk.
