MySQL 绿色版安装Window 系统

 为了便捷安装现在网上提供了许多的绿色版本MySQL安装包，下载后解压即可使用，但是MySQL 下载直接运行还是有一点小问题，需要把MYSQL 注册成为系统服务；

1.下载mysql绿色版本 例如：mysql-5.7.20-winx64;

2.修改数据库配置文件，j将my-default.in文件复制并命名为：my.ini;

# 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.

[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 = 128M

# 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.
# basedir = .....  #设置基目录
# datadir = .....  #设置数据目录
# port = .....     #设置MYSQL端口
# server_id = .....


# 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 

3.执行mysqld –install mysqld --defaults-file="D:Program Filesmysqlmy.ini",注册服务名，在windows服务中注册mysqld服务;

4.创建mysql的数据目录，执行 mysqld --initialize  创建数据库初始化文件;

5.执行net start mysql启动服务，net stop mysql关闭服务;

6.初次登录时，我们无法获取到数据库的root密码，所以需要my.ini文件中添加skip-grant-tables跳过权限验证。

7.将MYSQL配置系统环境变量，便于我们以后的操作；

8.执行mysql 命令，直接进入mysql系统；

8.登录成功，设置root初始化密码：

use mysql;
update user set password=password('123456') where user='root';

9.将my.ini中的skip-grant-tables去掉，重启服务。

10.命令行中链接数据库,修改数据库密码;

mysql -uroot -p
set password=password('123456'); -- 设置root密码

此时我们已经将绿色版本的MYSQL安装完成了，相比安装还是简单了许多，如果不熟悉配置文件，还是手动的一步一步的安装会更加靠谱。
