-绿色版mysql安装过程
1、先下载mysql文件，路径为：https://dev.mysql.com/downloads/mysql/
2、下载之后进行解压，目录自己选定，然后载解压后的bin目录下新建my.ini文件，文件的初始化信息如下：
# 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.
[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 = C:\Program Files\mysql-5.7.19-winx64
datadir = C:\Program Files\mysql-5.7.19-winx64\data
port = 3306
# 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

4、进入cmd，进入解压目录的bin路径下，mysqld –install（安装mysql服务命令），如果出现Install/Remove of the Service Denied!这个错误，请以管理员身份运行cmd.exe；当出现Service successfully installed.说明已经安装成功。
5、在运行mysqld –install命令（初始化配置文件），出现A temporary password is generated for root@localhost: f-N7sekNwKhf提示时，初始化完成。（此时记住f-N7sekNwKhf这个密码，下面要用到）
6、执行net start mysql命令，提示MySQL服务已经启动成功，则完成该操作。
7、执行mysql -uroot -p命令，登录mysql，密码为之前生成的密码。
8、执行set password=password(‘root’); 修改面密码。
