Unless this module is disabled, it masks packages provided by MySQL repositories. To disable the included module and make the MySQL repository packages visible, use the following command for dnf-enabled systems, replace yum in the command with dnf :.
This installs the package for MySQL server mysql-community-server and also packages for the components required to run the server, including packages for the client mysql-community-client , the common error messages and character sets for client and server mysql-community-common , and the shared client libraries mysql-community-libs.
Always run it to secure your MySQL installation:. It is important to remember the root password you set. For more information on the postinstallation procedures, see Chapter 9, Postinstallation Setup and Testing.
Install any packages of your choice with the following command, replacing package-name with name of the package:. See Section General Installation Guidance. Verifying the MD5 Checksum. Signature Checking Using Gpg4win for Windows. Compiler-Specific Build Characteristics.
Source Installation Methods. Source Installation Prerequisites. Choosing an Installation Package. This will remove some anonymous users and the test database, disable remote root logins, and load these new rules so that MySQL immediately respects the changes you have made. Once the script completes, your MySQL installation will be secured. You can now move on to creating a dedicated database user with the MySQL client.
Upon installation, MySQL creates a root user account which you can use to manage your database. This user has full privileges over the MySQL server, meaning it has complete control over every database, table, user, and so on.
This step outlines how to use the root MySQL user to create a new user account and grant it privileges. This plugin requires that the name of the operating system user that invokes the MySQL client matches the name of the MySQL user specified in the command, so you must invoke mysql with sudo privileges to gain access to the root MySQL user:.
The following will run your MySQL client with regular user privileges, and you will only gain administrator privileges within the database by authenticating:. These follow this general syntax:. This is immediately followed by an sign and then the hostname from which this user will connect.
If you only plan to access this user locally from your Ubuntu server, you can specify localhost. But it also prevents remote connections, which can complicate things when external programs need to interact with MySQL. The MySQL documentation recommends this plugin for users who want to log in with a password due to its strong security features. Be sure to change sammy to your preferred username and password to a strong password of your choosing:.
After creating your new user, you can grant them the appropriate privileges. The general syntax for granting user privileges is as follows:. You can grant multiple privileges to the same user in one command by separating each with a comma.
You can find the full list of available privileges in the official MySQL documentation. This will allow your MySQL user to grant any that it has to other users on the system. To install, use the yum command to specify the packages that you want to install.
For example:. To start the MySQL server use service :. To enable the server to be started and stopped automatically during boot, use chkconfig :. Which enables the MySQL server to be started and stopped automatically at the specified the run levels. The database tables are automatically created for you, if they do not already exist. On Debian and related distributions, there are two packages for MySQL in their software repositories, mysql-client and mysql-server , for the client and server components respectively.
You should specify an explicit version, for example mysql-client To download and install, including any dependencies, use the apt-get command, specifying the packages that you want to install. Before installing, make sure that you update your apt-get index files to ensure you are downloading the latest available version.
