1、解壓MySQL-5.7.17-winx64.zip到目錄D:/PRogram Files/mysql-5.7.17-winx64

2、配置環境變量：

3、修改D:/Program Files/mysql-5.7.17-winx64目錄下my-default.ini文件，配置basedir和datadir：

# 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 = .....# datadir = .....# port = .....# server_id = .....#mysql所在的目錄basedir=D:/Program Files/mysql-5.7.17-winx64 #mysql所在的目錄/datadatadir=D:/Program Files/mysql-5.7.17-winx64/data# 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、以管理員權限運行cmd，并進入到 D:/Program Files/mysql-5.7.17-winx64/bin 目錄下，輸入命令 ==> mysqld -install
5、初始化mysql命令==>  mysqld --initialize
6、安裝成功后啟動服務==>  net start mysql 
7、登陸服務使用命令 ==> mysql -u root -p，輸入密碼按enter就好。mysql5.7.17給了一個初始密碼，在D:/Program Files/mysql-5.7.17-winx64/data/MSI.err文件中，或者在D:/Program Files/mysql-5.7.17-winx64目錄下搜索*.err
8、修改密碼為123456==>  set passWord for root@localhost=password('123456');
