1. 下载mysql zip 安装包:mysql-5.7.22-win32
路径:https://dev.mysql.com/downloads/mysql/5.6.html#downloads
安装参考:https://www.jb51.net/article/134178.htm
1)解压mysql-5.7.22-win32 到F:\mysql
2)在F:\mysql\mysql-5.7.22-win32下新建一个my.ini文件,内容:

[mysql]
# 设置mysql客户端默认字符集
default-character-
set
=utf8
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=F:\mysql\mysql-5.7.22-win32
# 设置mysql数据库的数据的存放目录
datadir=F:\mysql\mysql-5.7.22-win32\data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-
set
-server=utf8
#开启查询缓存
explicit_defaults_for_timestamp=
true
skip-grant-tables
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
|
3)设置环境变量:
在环境变量path中增加F:\mysql\mysql-5.7.22-win32\bin ,记得两个路径间加分号;
4)右键 cmd.exe,选择以管理员方式运行
mysqld --initialize --user=mysql --console
结果:
F:\mysql\mysql-5.7.22-win32>mysqld --initialize --user=mysql --console
2018-07-11T12:12:17.966314Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is
deprecated. Please use --explicit_defaults_for_timestamp server option (see doc
umentation for more details).

localhost: #MvUKmukE1f1
#MvUKmukE1f1 为数据库的初始密码。
5)安装服务
mysqld install
注意要去F:\mysql\mysql-5.7.22-win32\bin目录下运行此命令,不然启动服务会出错。
6)启动服务
net start MySQL
7)停止服务
net stop MySQL
8)登录数据库
mysql -u root -p
密码:#MvUKmukE1f1
9)修改登录密码
登录mysql后输入如下命令,mysql123是设置的新密码
set password for root@localhost=password('mysql123');
如下,表示修改成功。
Query OK, 0 rows affected, 1 warning (0.09 sec)
10) 重新登录mysql
mysql -u root -p
密码:mysql123
2. 如果用python操作mysql需要使需要MySQL-python驱动
下载地址:https://pypi.python.org/pypi/MySQL-python/,最开始用源码MySQL-python-1.2.5.zip安装未成功,出现一些错误,如
1)error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27
2)_mysql.c(42) : fatal error C1083: 无法打开包括文件:“config-win.h”: No such file or directory
之后直接用MySQL-python-1.2.5.win32-py2.7.exe 安装成功(可在优快云下载)。
3.python连接mysql测试:
C:\Users\Administrator>python
Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32
Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> import MySQLdb
>>>
如果没有报错,说明安装好了。
用python操作数据库参考:https://www.cnblogs.com/fnng/p/3565912.html
1)登录mysqls,创建数据库test:
CREATE DATABASE test;
2)查看数据库:
show databases;
3)在cmd运行如下python脚本在test数据库的 student表插入一条记录
#!/usr/bin/python
# -*- coding: utf-8 -*-
import MySQLdb
#链接数据库
conn= MySQLdb.connect(
host='localhost',
port = 3306,
user='root',
passwd='mysql123',
db ='test',
)
cur = conn.cursor()
#创建数据表
cur.execute("create table student(id int ,name varchar(20),class varchar(30),age varchar(10))")
#插入一条数据
cur.execute("insert into student values('2','Tom','3 year 2 class','9')")
cur.close()
conn.commit()
conn.close()
4)登录mysql数据库查看表记录:
mysql> use test;
mysql> select * from student;
可以看到如下记录:
mysql> select * from student;
+------+------+----------------+------+
| id | name | class | age |
+------+------+----------------+------+
| 2 | Tom | 3 year 2 class | 9 |
+------+------+----------------+------+
1 row in set (0.00 sec)
5)用python脚本 mysql_test.py 查看插入的数据库记录:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import MySQLdb
conn= MySQLdb.connect(
host='localhost',
port = 3306,
user='root',
passwd='mysql123',
db ='test',
)
cur = conn.cursor()
#获得表中有多少条数据
aa=cur.execute("select * from student")
print aa
#打印表中的多少数据
info = cur.fetchmany(aa)
for ii in info:
print ii
cur.close()
conn.commit()
conn.close()
运行此脚本后,结果:
F:\mysql>python mysql_test.py
1
(2L, 'Tom', '3 year 2 class', '9')
