MariaDB 설치

Please refer to the procedure below and install MariaDB 10.1.20 or later.

  1. Linux

  2. Mac

  3. Windows

Create user and database after installing DB

The basic procedure is to connect to MariaDB as root user, create yona user, create DB, and give all permissions of yona user to DB.

Connect to MariaDB with root

mysql -uroot

Create user yona and set password. 'yonadan' is just example, so change it.

create user 'yona'@'localhost' IDENTIFIED BY 'yonadan';

To use UTF8 extended chars, set file format to BARACUDA.

set global innodb_file_format = BARRACUDA;
set global innodb_large_prefix = ON;

create database yona
  DEFAULT CHARACTER SET utf8mb4
  DEFAULT COLLATE utf8mb4_bin
;

Grant priviledges

GRANT ALL ON yona.* to 'yona'@'localhost';

Exit to the shell with exit command and check that yona DB is available and yona user is connected normally. Note that the letter after the -p is the password created above.

mysql -u yona -p'yonadan'
use yona

Please make a /etc/my.cnf file and add the following.

(If you are a mac os user, add the following line to ~/.my.cnf file) Example: https://github.com/yona-projects/yona/blob/next/support-script/mariadb/my.cnf

  • It is supposed to use utf8mb4 to support Unicode 4Byte extension strings.
  • lower_case_table_name=1 is option makes the case of table or column names case insensitive.
  • collation-server is criteria options when sorting.
[client]
default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4

[mysqld]
collation-server=utf8mb4_unicode_ci
init-connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
lower_case_table_names=1
innodb_file_format=barracuda
innodb_large_prefix=on

Also, see configuring-mariadb-with-mycnf

Now, let's start to install Yona!
