摘要
在官网下载了mysql，版本mysql-5.7.17-winx64，免安装的压缩包，解压后。放在MySql的文件夹中。电脑系统win10 x64.
配置文件
# 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

[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\mysql-5.7.17-winx64
datadir =C:\Program Files\MySql\mysql-5.7.17-winx64\data
# port = .....
# 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
修改了basedir和datadir配置。
添加环境变量
我的电脑->属性->环境变量-PATH
C:\Program Files\MySql\mysql-5.7.17-winx64\bin;
管理员身份运行CMD，并进入bin目录。安装mysql。命令：mysqld -install
然后启动mysql。
出现这个错误尝试很多方法解决，最后将自己手动创建的data文件夹删除，然后运行初始化命令而解决。
初始化命令：mysqld --initialize
初始化过程中，会data创建很多的文件，如图所示：
