【初心者向け】MySQLでローカルにDBを作成する方法

Last updated at Posted at 2020-10-17

MySQLを勉強するためにローカルでDBを作成する方法を調べたので、備忘録的まとめ。
※MySQLが使える状態であることが前提。

1.MySQLを起動

$ mysql.server start
Starting MySQL
 SUCCESS! 

2.rootユーザーでログイン

2020-10-17T13:43:42.6NZ mysqld_safe A mysqld process already exists
mysql -u root // これを入力する
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.7.31 Homebrew

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

3.DBを作成

mysql> create database testDB; // これを入力する
Query OK, 1 row affected (0.01 sec)

4.DBを確認

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| testDB             | // 作成したDBが入っている
+--------------------+
7 rows in set (0.00 sec)

5.DBを選択する

mysql> use testDB; // これを入力する
Database changed

6.テーブルを確認

mysql> show tables; // これを入力する
Empty set (0.00 sec)

→DBを作成しただけで、中身は空の状態

ここまでで、DBの作成は完了。
