#MYSQL COMMAND LINE PASSWORD#
With the root password set, you can at least be assured (to some degree) that no one is going to be able to misuse your MySQL root privileges.
Where “NEWPASSWORD” is the intended password. First, set the root password with the following command: To set a password, use the mysqladmin tool with the password option. If you don’t set a password, anyone can connect to your database to edit databases, drop databases, remove databases, and so on. So this is the perfect time to set certain passwords, especially for the root user. You can also add the latter command into the /etc/rc.local file to have the daemon start at boot.Īt this point, since I’ve already established that no passwords have been set, you can connect to MySQL without a single password. Starting the daemon this way will present the prompt when the command runs. The second way to start the MySQL daemon-and the way I prefer-is to run the command /etc/rc.d/init.d/mysqld start. When starting in this manner, the only way to get your prompt back is to put the process into a zombie state (by hitting Z). The first-and more universal-is by running (as root) the command mysql_safe, which, when run from the command, will not give back a command prompt. On Red Hat-based distributions, there are two ways to start your database. With that in mind, you’ll first need to get your database engine running. I am going to assume that you have not taken any steps in administering your MySQL database, so that passwords have not been set and the daemon is not running. This article assumes you have a working MySQL installation on your Linux machine as well as a fundamental understanding of database design. From there, you’ll be on the fast track to mastering the intricacies of MySQL. In this Daily Feature, I am going to acquaint you with Linux’s MySQL command-line interface so that you will be able to connect to your MySQL database in order to create and use a simple database. Most good databases require command-line interfaces that many administrators are not yet comfortable working with. Unfortunately, database administration is not a simple task. Because of this, duties that once belonged to the database administrator are quickly becoming the duties of the systems/network administrators. From Web sites to employee records to vendor listings to payrolls, databases affect nearly all levels of the enterprise. Introduction to common command line MySQL instructions and configurationsĭatabases are all the rage for one good reason: You need them to do just about anything.
