安装MySQL

1. 下载zip包
   进入官网下载页面：http://dev.mysql.com/downloads/mysql/
   下载mysql-5.6.23-win32.zip：
   

   Windows (x86, 32-bit), ZIP Archive	5.6.23	342.3M	Download
   (mysql-5.6.23-win32.zip)	MD5: d55ea458590c92060a790ba22e9b4222 | Signature

2. 解压zip包
   解压zip包到E:developdatabasemysql
3. 配置环境变量
   新增MYSQL_HOME变量
   

   MYSQL_HOME
   E:developdatabasemysqlmysql-5.6.21

   在PATH变量后追加

   ;%MYSQL_HOME%in 

4. 修改配置文件
   复制my-default.ini为自己使用的配置文件（如： jian.ini），编辑后最终得jian.ini以下内容：
   

   # For advice on how to change settings please see
   # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
   # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
   # *** default location during install, and will be replaced if you
   # *** upgrade to a newer version of MySQL.
   
   [mysql]  
   #设置mysql客户端的字符集  
   default-character-set = utf8
   
   [mysqld]
   
   # Remove leading # and set to the amount of RAM for the most important data
   # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
   innodb_buffer_pool_size = 256M
   
   # Remove leading # to turn on a very important data integrity option: logging
   # changes to the binary log between backups.
   # log_bin
   
   # These are commonly set, remove the # and set as required.
   # 设置mysql的安装目录
   basedir = E:/develop/database/mysql/mysql-5.6.21
   # 设置mysql数据库的数据的存放目录
   datadir = E:/develop/database/mysql/mysql-5.6.21/data
   # 设置绑定端口
   port = 3366
   # server_id = .....
   #设置服务器段的字符集  
   character_set_server = utf8
   # 允许最大连接数
   max_connections = 10
   
   # Remove leading # to set options mainly useful for reporting servers.
   # The server defaults are faster for transactions and fast SELECTs.
   # Adjust sizes as needed, experiment to find the optimal values.
   # join_buffer_size = 128M
   # sort_buffer_size = 2M
   # read_rnd_buffer_size = 2M 
   
   sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

5. 安装
   以管理员身份运行cmd，输入命令：
   

   mysqld install jianSQLService --defaults-file="E:developdatabasemysqlmysql-5.6.21jian.ini"

6. 启动
   

   net start jianSQLService

7. 登录
   

   mysql -P3366 -uroot -p

   参数说明：
   -h: mysql服务器地址。若本机，可省略；
   -P: mysql服务器端口。若默认3306，可省略；
   -u: 用户名；
   -p: 密码。密码为空，可省略。

8. 修改root密码
   

   mysql> update mysql.user set password=password("jian") where User="root";
   Query OK, 3 rows affected (0.00 sec)
   Rows matched: 3  Changed: 3  Warnings: 0
   
   mysql> flush privileges;
   Query OK, 0 rows affected (0.00 sec)

9. 关闭
   

   net stop jianSQLService

10. 卸载
    慎用。在放弃使用MySQL时，才用到此项。
    以管理员身份运行cmd，输入命令：
    

    mysqld –remove

    或者

    sc delete jianSQLService
