1）建数据库：
CREATE DATABASE `test` /*!40100 DEFAULT CHARACTER SET utf8 */;  

2）给库授权：
grant all privileges on test.* to root@127.0.0.1 identified by "test123";
flush privileges;

3）建表：
CREATE TABLE `person` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(50) NOT NULL, `age` tinyint(4) DEFAULT '0', `sex` enum('男','女','人妖') NOT NULL DEFAULT '人妖', `salary` decimal(10,2) NOT NULL DEFAULT '250.00', `hire_date` date NOT NULL, `dept_id` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=utf8;

4）灌入数据：
INSERT INTO `person` VALUES ('1', 'alex', '28', '人妖', '53000.00', '2010-06-21', '1'); INSERT INTO `person` VALUES ('2', 'wupeiqi', '23', '男', '8000.00', '2011-02-21', '1'); INSERT INTO `person` VALUES ('3', 'egon', '30', '男', '6500.00', '2015-06-21', '1'); INSERT INTO `person` VALUES ('4', 'jingnvshen', '18', '女', '6680.00', '2014-06-21', '1'); -- 销售部 INSERT INTO `person` VALUES ('5', '歪歪', '20', '女', '3000.00', '2015-02-21', '2'); INSERT INTO `person` VALUES ('6', '星星', '20', '女', '2000.00', '2018-01-30', '2'); INSERT INTO `person` VALUES ('7', '格格', '20', '女', '2000.00', '2018-02-27', '2'); INSERT INTO `person` VALUES ('8', '周周', '20', '女', '2000.00', '2015-06-21', '2');

5）查询：
mysql> select * from person;
+----+------------+------+--------+----------+------------+---------+
| id | name       | age  | sex    | salary   | hire_date  | dept_id |
+----+------------+------+--------+----------+------------+---------+
|  1 | alex       |   28 | 人妖   | 53000.00 | 2010-06-21 |       1 |
|  2 | wupeiqi    |   23 | 男     |  8000.00 | 2011-02-21 |       1 |
|  3 | egon       |   30 | 男     |  6500.00 | 2015-06-21 |       1 |
|  4 | jingnvshen |   18 | 女     |  6680.00 | 2014-06-21 |       1 |
+----+------------+------+--------+----------+------------+---------+

6)写Python连接代码，mysqlconn.py:
import pymysql conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='test123',db='test') cur = conn.cursor() cur.execute("SELECT * FROM person") data=cur.fetchall() #for r in cur.fetchall(): for d in data :            #print(r)            #cur.close()     print("ID: "+str(d[0])+'  名字： '+str(d[1])+"  性别： "+str(d[2])) cur.close() conn.close()

7)运行mysqlconn.py：
python  mysqlconn.py
ID: 1  名字： alex  性别： 28
ID: 2  名字： wupeiqi  性别： 23
ID: 3  名字： egon  性别： 30
ID: 4  名字： jingnvshen  性别： 18

最后备注，mysql -h localhost -u root -p  （/root/.my.cnf里默认是Localhost的密码）
cat /root/.my.cnf 里的密码，可以登录。 ]]> http://www.jackxiang.com/post//#blogcomment <user@domain.com> Thu, 01 Jan 1970 00:00:00 +0000 http://www.jackxiang.com/post//#blogcomment
