樹莓派安裝mysql資料庫並且通過python來進行儲存操作

具體的安裝資料庫的操作詳見:http://blog.csdn.net/huayucong/article/details/49736427
安裝python-Mysqldb
安裝完成後,加上我之前有一片的溫溼度監測的程式碼:
(mysql資料庫在樹莓派上;
使用者名稱密碼:root,123456;
埠:3306;
地址:localhost或者127.0.0.1;
資料庫:testdb;
表:temp;
列名:time,temperature,humidity)
建立資料庫和表的程式碼沒寫進去,可以在外面建立或者寫在裡面。個人建議是寫在外面。
