在 Windows7 上按照 MySQL5.7

1、从官网下载最新版本的 MySQL，这里下载的是 mysql-5.7.17-win32；

2、将下载的 mysql-5.7.17-win32.zip 解压到指定的文件夹下，这里的目标文件夹是 E:\develop；

3、复制 my-default.ini 文件并将新的文件命名为 my.ini；

4、根据自己的 MySQL 解压到的目录配置 my.ini 文件，这里的 my.ini 配置如下：<br/>
	####################配置文件开始###################

	 # For advice on how to change settings please see

	 # http://dev.mysql.com/doc/refman/5.7/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.

	 [client]

	 default-character-set=utf8

	 [mysqld]<br/>
	 character-set-server=utf8<br/>
	 collation-server=utf8_general_ci

	 port=3306

	 datadir  ="E:\develop\mysql-5.7.17-win32/data/"

	 tmpdir   ="E:\develop\mysql-5.7.17-win32/data/"

	 socket   ="E:\develop\mysql-5.7.17-win32/data/mysql.sock"

	 log-error="E:\develop\mysql-5.7.17-win32/data/mysql_error.log"

	 sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

	 #sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

	#################### 配置文件结束 ###################

5、配置 MySQL 的环境变量，在系统区域创建 MySQL_HOME 变量，值为 MySQL 的安装目录，这里的是 E:\develop\mysql-5.7.17-win32；<br/>
   将 MySQL_HOME 加入到 path 变量中，即 %MySQL_HOME%\bin;

6、以管理员身份打开命令行工具 CMD 并进入到 MySQL 的命令 bin 目录，这里为 E:\develop\mysql-5.7.17-win32\bin；

7、执行如下命令：<br/>
	7.1 mysqld --initialize --user=mysql --console<br/>
	创建用户表，生成如下信息：<br/>
		E:\develop\mysql-5.7.17-win32\bin>mysqld --initialize --user=mysql --console<br/>
		2017-01-04T01:02:43.711502Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'E<br/>
		RROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will<br/>
		be merged with strict mode in a future release.<br/>
		2017-01-04T01:02:44.326080Z 0 [Warning] InnoDB: New log files created, LSN=45790

		2017-01-04T01:02:44.675125Z 0 [Warning] InnoDB: Creating foreign key constraint<br/>
		system tables.<br/>
		2017-01-04T01:02:44.791639Z 0 [Warning] No existing UUID has been found, so we a<br/>
		ssume that this is the first time that this server has been started. Generating<br/>
		a new UUID: 802e6595-d219-11e6-bcf8-10604b7f46dc.<br/>
		2017-01-04T01:02:44.806141Z 0 [Warning] Gtid table is not ready to be used. Tabl<br/>
		e 'mysql.gtid_executed' cannot be opened.<br/>
		2017-01-04T01:02:44.814642Z 1 [Note] A temporary password is generated for root@<br/>
		localhost: tFhwFqiA)0oQ<br/>
	<strong>其中的 tFhwFqiA)0oQ 为 MySQL 为我们生成的临时密码，一定要记下来，后面要用到；</strong><br/>
	7.2 安装服务：<br/>　　　　　　mysqld install MySQL --defaults-file="E:\develop\mysql-5.7.17-win32\my.ini"<br/>　　　　 7.3 启动服务：<br/>　　　　　　　　net start mysql<br/>
	7.4 进入到 MySQL 命令行界面：<br/>
		mysql -uroot -p<br/>　　　　　　　　　 在提示下输入步骤 7.1 中生成的临时密码；<br/>
	7.5 修改用户 root 的密码（必须修改，不然无法通过）：<br/>
		set password = password('123456')

8、查看 MySQL 的字符编码：<br/>
	SHOW VARIABLES LIKE '%character%';

	mysql> SHOW VARIABLES LIKE '%character%';<br/>
	+--------------------------+-----------------------------------------------+<br/>
	| Variable_name            | Value                                         |<br/>
	+--------------------------+-----------------------------------------------+<br/>
	| character_set_client     | utf8                                          |<br/>
	| character_set_connection | utf8                                          |<br/>
	| character_set_database   | utf8                                          |<br/>
	| character_set_filesystem | binary                                        |<br/>
	| character_set_results    | utf8                                          |<br/>
	| character_set_server     | utf8                                          |<br/>
	| character_set_system     | utf8                                          |<br/>
	| character_sets_dir       | E:\develop\mysql-5.7.17-win32\share\charsets\ |<br/>
	+--------------------------+-----------------------------------------------+<br/>
	8 rows in set, 1 warning (0.00 sec)<br/>
	说明我们的字符编码配置都为 UTF8。

9、好了，至此我们完成了 MySQL 的安装，开始愉快的编程之旅吧！
