This creates a table with a customer ID field of the type INT for integer (auto-incremented for new records, used as the primary key), as well as two fields for storing the customer’s name: use testdb Ĭreate table customers (customer_id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, first_name TEXT, last_name TEXT) Log back in as testuser: mysql -u testuser -pĬreate a sample table called customers. You can shorten this process by creating the user while assigning database permissions: create database testdb Grant all on testdb.* to 'testuser' identified by 'password' In the example below, testdb is the name of the database, testuser is the user, and password is the user’s password: create database testdb Nowarning (\w) Don't show warnings after every statement.įor server side help, type 'help contents' Warnings (\W) Show warnings after every statement.

It is recommended that you answer yes to these options. You will be given the choice to change the MariaDB root password, remove anonymous user accounts, disable root logins outside of localhost, and remove test databases. Run the mysql_secure_installation script to address several security concerns in a default MariaDB installation: sudo mysql_secure_installation If you decide to bind MariaDB to your public IP, you should implement firewall rules that only allow connections from specific IP addresses. For information on connecting to a remote database using SSH, see our MySQL remote access guide, which also applies to MariaDB.Īllowing unrestricted access to MariaDB on a public IP not advised but you may change the address it listens on by modifying the bind-address parameter in /etc/my.cnf. MariaDB will bind to localhost (127.0.0.1) by default. Install and Start MariaDB sudo yum install mariadb-serverĮnable MariaDB to start on boot and then start the service: sudo systemctl enable mariadb The first command should show your short hostname, and the second should show your fully qualified domain name (FQDN). You may also wish to set the timezone, configure your hostname, create a limited user account, and harden SSH access. See our Getting Started with Linode and Creating a Compute Instance guides.įollow our Setting Up and Securing a Compute Instance guide to update your system and configure the hostname. If you have not already done so, create a Linode account and Compute Instance. If you’re not familiar with the sudo command, you can check our Users and Groups guide.
