Mariadb用戶操做/數據庫基本操做 (一)

第一部分 基礎與軟鏈接

啓動數據庫: `$ mysql.server start` 關閉數據庫: `$ mysql.server stop` 連接數據庫: `$ mysql -uroot`

brew 安裝位置

/usr/local/Cellar/mariadb/10.1.19/

設置軟鏈接
此時mysql 與 mysqladmin 所在的路徑爲

/usr/local/Cellar/mariadb/10.1.19/bin/mysql /usr/local/Cellar/mariadb/10.1.19/bin/mysqladmin

設置的具體步驟:

$ ln -s /usr/local/Cellar/mariadb/10.1.19/bin/mysql /usr/bin $ ln -s /usr/local/Cellar/mariadb/10.1.19/bin/mysqladmin /usr/bin

第二部分 數據庫ROOT更改密碼

$ mysqladmim -u root -p flush-privileges password

在此會提示輸入舊密碼, 可是當你輸入新密碼時不會顯示在桌面上;

$ mysqladmim -u root -p flush-privileges password Enter password: New password: Confirm new password:

第三部分 操做用戶並設置權限

3.0 查看錶結構---DESC (Description)

MariaDB [typedb] > DESC 表名

3.1 羅列用戶:

> SELECT User, Host FROM mysql.user;

+------+-----------------------+

| User | Host                  |

+------+-----------------------+

| root | 127.0.0.1             |

| root | ::1                   |

|      | bwf-huanghaowei.local |

| root | bwf-huanghaowei.local |

|      | localhost             |

| root | localhost             |
