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.

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 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.
