MySql 5.7.17免安装配置教程详解

1、下载mysql/' target='_blank'>mysql-5.7.17-winx64.zip安装包（链接：https://dev.MySQL.com/downloads/mysql/）

2、解压安装包。

D:\DevelopTool\mysql-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:\DevelopTool\mysql-5.7.17-winx64\data

4、配置启动文件

　　把 D:\DevelopTool\mysql-5.7.17-winx64\my-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=./../datadatadir=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=20character_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=truesql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

5、初始化数据目录

mysqld --defaults-file="D:\DevelopTool\mysql-5.7.17-winx64\my.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mysqlmysql -u root -p#移除mysqlmysqld -remove
