Start up MySQL Server for the first time

You should see the following message when you use the command
service mysqld start
to start up MySQL server for the first time:
 Initializing MySQL database:  Installing MySQL system tables...
 Filling help tables...

 To start mysqld at boot time you have to copy
 support-files/mysql.server to the right place for your system

 To do so, start the server, then issue the following commands:

 /usr/bin/mysqladmin -u root password 'new-password'
 /usr/bin/mysqladmin -u root -h fedora1 password 'new-password'

 Alternatively you can run:

 which will also give you the option of removing the test
 databases and anonymous user created by default.  This is
 strongly recommended for production servers.

 See the manual for more instructions.

 You can start the MySQL daemon with:
 cd /usr ; /usr/bin/mysqld_safe &

 You can test the MySQL daemon with mysql-test-run.pl
 cd /usr/mysql-test ; perl mysql-test-run.pl

 Please report any problems with the /usr/bin/mysqlbug script!

 Starting mysqld:                                           [  OK  ]

Reset MySQL server's root password

As you can see from the previous section, MySQL server default setup does not has password for the root user. You can connect to MySQL server as root on the local machine without providing password. However, if your have set the password for root and later forget the password, the following show you the steps to reset the root password on a Fedora system (tested on Fedora 13):

Stop the MySQL Server

# service mysqld stop

Restart the MySQL server with --skip-grant-tables

Reset root password

Restart MySQL server normally

  • Run the following command:
# service mysqld restart
