service mysqld startto start up MySQL server for the first time:
Initializing MySQL database: Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! 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: /usr/bin/mysql_secure_installation 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! [ OK ] Starting mysqld: [ OK ]
- If you are using Fedora 16 or later, MySQL will be started using "systemctl" and no message will be displayed when MySQL server starts up successfully.
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
