MariaDB 설치 / 초기 설정

소개

MariaDB 설치에서 초기 설정을 할 기회가 있었으므로 메모 해 둔다.

환경 정보

• OS: CentOS7.1

단계

Install

다음 명령으로 설치할 수 있습니다.

$ sudo yum install -y mariadb mariadb-devel mariadb-server

설정 파일 생성

다음의 명령으로 최소 구성의 서버 설정 파일을 복사한다.

$ cp -p /usr/share/mysql/my-small.cnf /etc/my.cnf.d/server.cnf

기본 상태에서도 동작하지만, 다음 행을 추가하여 일본어 설정과 data 디렉토리를 변경할 수있다.

[client] default-character-set = utf8 [mysqld] datadir = /datas character-set-server = utf8

초기 설정

다음으로 초기 설정한다.
초기 root 암호 입력없이 Enter 키를 누르면 다음 처리가 진행된다.

$ sudo systemctl start mariadb.service $ sudo /usr/bin/mysql_secure_installation /usr/bin/mysql_secure_installation: 行 379: find_mysql_client: コマンドが見つかりません NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB       SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user.  If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! Reloading privilege tables..  ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them.  This is intended only for testing, and to make the installation go a bit smoother.  You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y  ... Success! Normally, root should only be allowed to connect from 'localhost'.  This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y  ... Success! By default, MariaDB comes with a database named 'test' that anyone can access.  This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y  - Dropping test database...  ... Success!  - Removing privileges on test database...  ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y  ... Success! Cleaning up... All done!  If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! $

DB 생성

우선 root 사용자로 로그인한다.

$ mysql -uroot -p Enter password: Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 4300 Server version: 5.5.41-MariaDB MariaDB Server Copyright (c) 2000, 2014, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> CREATE DATABASE ${db_name} DEFAULT CHARACTER SET utf8;

권한 설정

다음의 명령으로 생성 한 DB에 특정 사용자의 액세스 권한을 설정한다.
$ {user} @ '%'를 지정하여 모든 IP에서의 접근을 허용하고있다.

MariaDB [(none)]> GRANT ALL PRIVILEGES ON ${db_name}.* TO ${user}@'%' IDENTIFIED BY '${password}';

테이블 작성

만든 사용자로 로그인하여 Table을 생성한다.
다음 간단한 테이블, id와 name 컬럼을 가진 테이블을 작성하고있다.

MariaDB [(none)]> exit $ mysql -u${user} -D${db_name} -p Enter password: Welcome to the MariaDB monitor.  Commands end with ; or \g. Your MariaDB connection id is 13 Server version: 5.5.41-MariaDB MariaDB Server Copyright (c) 2000, 2014, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [${db_name}]> CREATE TABLE ${table_name} ( ¥     id INT AUTO_INCREMENT PRIMARY KEY,¥     name VARCHAR(100)¥     ); Query OK, 0 rows affected (0.01 sec) MariaDB [${db_name}]> DESC ${table_name}; +-------+--------------+------+-----+---------+----------------+ | Field | Type         | Null | Key | Default | Extra          | +-------+--------------+------+-----+---------+----------------+ | id    | int(11)      | NO   | PRI | NULL    | auto_increment | | name  | varchar(100) | YES  |     | NULL    |                | +-------+--------------+------+-----+---------+----------------+ 2 rows in set (0.01 sec) MariaDB [${db_name}]>
