To do this, add the following line in /etc/my.cnf.d/server.cnf: ![]() If MariaDB is only needed for the localhost, you can improve security by not listening on TCP port 3306, and only listening on Unix sockets instead. This will bind to both 127.0.0.1 and ::1, and enable MariaDB to receive connections both in IPv4 and IPv6.Įnable access locally only via Unix socketsīy default, MariaDB is accessible via both Unix sockets and the network. In order to restrict MariaDB to listen only to the loopback address, add the following line in /etc/my.cnf.d/server.cnf: Listen only on the loopback addressīy default, MariaDB will listen on the 0.0.0.0 address, which includes all network interfaces. To prevent MySQL from listening on an external interface, see the #Listen only on the loopback address and #Enable access locally only via Unix sockets sections. Warning: After running this, please note that TCP port 3306 will still be open, but refusing connections with an error message. The mariadb-secure-installation command will interactively guide you through a number of recommended security measures, such as removing anonymous accounts and removing the test database: $ mariadb-tzinfo-to-sql timezone_file timezone_name | mariadb -u root -p mysql Optionally, you may populate the table with specific time zone files: $ mariadb-tzinfo-to-sql /usr/share/zoneinfo | mariadb -u root -p mysql To populate the time zone tables with all the time zones: They need to be populated if you are planning on using CONVERT_TZ() in SQL queries. Stop rvice, mount /var/lib/mysqltmp/ and start rvice.Īlthough time zone tables are created during the installation, they are not automatically populated. ![]() Tmpfs /var/lib/mysqltmp tmpfs rw,gid=mysql,uid=mysql,size=100M,mode=0750,noatime 0 0Īdd to your /etc/my.cnf.d/server.cnf file under the mysqld group: For example, it is used to perform disk based large sorts, as well as for internal and explicit temporary tables.Ĭreate the directory with appropriate permissions:Īdd the following tmpfs mount to your /etc/fstab file: The directory used by MariaDB for storing temporary files is named tmpdir. See #Maintenance to optimize and check the database health. Changing the character set does not change existing table formats, only newly created tables, and the protocol interaction that fetches data. Īppend the following values to the main configuration file located at /etc/my.cnf.d/my.cnf: UTF8MB4 is recommended over UTF-8 since it allows full Unicode support.Users using the default (character) settings may want to skip this section. ![]() ![]() The mariadb package already uses utf8mb4 as charset and utf8mb4_unicode_ci as collation.See this entry of the Knowledge Base for more information. cnf extension to ensure that upgrades preserve your configuration.ĭepending on the scope of the changes you want to make (system-wide, user-only.), use the corresponding file. MariaDB configuration options are read from the following files in the given order (according to mysqld -help -verbose | tail -20 output):Ĭreate a configuration file in /etc/my.cnf.d/ with a. MariaDB> GRANT ALL PRIVILEGES ON mydb.* TO quit # mariadb -u root -p MariaDB> CREATE USER IDENTIFIED BY 'some_pass' In the below example, the user monty with some_pass as password is being created, then granted full permissions to the database mydb: To log in as root on the MariaDB server, use the following command:Ĭreating a new user takes two steps: create the user grant privileges. Once you have started the MariaDB server and added a root account, you may want to change the default configuration. To simplify administration, you might want to install a front-end. Note: Before continuing, it is recommended to improve the initial security of MariaDB installation.
