# 1.1.1.安裝My SQL (Mac OS X)

* 1.先到My SQL官網, 選擇Downloads-> Community, 下載DMG Archieve
* 2.若是沒有會員得先註冊會員, 隨後將會發出驗證信給你
* 3.登入後繼續進行下載
* 4.打開下載回來的.dmg檔進行安裝, 一直按確認即可,注意當安裝結束後會出現一組暫時的密碼, 將密碼記下來, 當access到My SQL時會使用到 (密碼很重要)
* 5.確認安裝是否成功: 打開command line輸入

  ```
    cd /usr/local/mysql
    sudo ./bin/mysqld_safe
  ```

  * 接著他會停住一段時間, 按ctrl+d跳出來後再次輸入:

    ```
     bg
    ```
  * 畫面會出現:

    ```
     [1]+ sudo ./bin/mysqld_safe &
    ```
  * 再次輸入bg, 畫面會出現:

    ```
     -bash: bg: job 1 already in background
    ```
  * 表示My SQL已在在背景中run起來了
* 6.將My SQL的路徑設到bash\_profile中, 進到My SQL command:
  * 在command line中輸入:

    ```
    sudo nano ~/.bash_profile
    ```
  * 並在編輯器加入下面code:

    ```
    export PATH=/usr/local/mysql/bin:$PATH
    ```
  * 關閉並重新開一個新的command line, 輸入:

    ```
     mysql -u root -p
    ```
  * 此時要輸入的密碼就是一開始記下來的密碼,輸入後即可進到My SQL的命令列中
