1、下载mysql-5.7.17-winx64.zip安装包（链接：https://dev.mysql.com/downloads/mysql/）
2、解压安装包。
D:DevelopToolmysql-5.7.17-winx64 #解压目录
3、在解压目录下创建一个名为data的文件夹，用来存放数据
D:DevelopToolmysql-5.7.17-winx64data
4、配置启动文件
把 D:DevelopToolmysql-5.7.17-winx64my-default.ini 文件copy一份，重新命名为 my.ini ，修改里面的参数，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 = ..... # datadir = ..... # port = ..... # server_id = ..... ######################### # basedir 为安装文件解压后的目录 ｜ basedir和datadir 可以使用相对路径 # basedir=./.. basedir=D:\DevelopTool\mysql-5.7.11-winx64 # datadir 为用来存放数据的目录 # datadir=./../data datadir=D:\DevelopTool\mysql-5.7.11-winx64\data # port 为端口号 port=3306 # mar_connections为最大连接数 max_connections=20 character_set_server=utf8 # 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 explicit_defaults_for_timestamp=true sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
5、初始化数据目录
mysqld --defaults-file="D:DevelopToolmysql-5.7.17-winx64my.ini" --initialize-insecure
它会初始化 data 目录，在执行此命令前请先把data目录下的所有文件先删除，否则会失败
可以选择用 --initialize-insecure 或者 --initialize 来初始化，--initialize-insecure 初始化root密码为空，如果用 --initialize来初始化，会产生一个随机密码
执行成功后，在data目录下会生成mysql，perofrmance_schema，sys等目录文件
6、安装和启动mysql服务
#安装服务 mysqld -install #启动服务 net start mysql #进入mysql mysql -u root -p #移除mysql mysqld -remove
