window安装MySQL5.7.28

在官网下载压缩包，找个好地方放好，然后去配置环境变量

 

保存my.ini文件

[mysqld]
# 设置服务端使用的字符集为utf-8
character-set-server=utf8
# 绑定IPv4地址
bind-address = 0.0.0.0
# 设置mysql的端口号
port = 3306
# 设置mysql的安装目录(能看到bin即可)
basedir=D:\mysql-5.7.28-winx64
# 设置mysql数据库的数据的存放目录
datadir=G:\other\Mysql5.7\data
# 允许最大连接数
max_connections=2000
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 设置mysql以及数据库的默认编码
[mysql]
default-character-set=utf8
[mysql.server]
default-character-set=utf8
# 设置客户端默认字符集
[client]
default-character-set=utf8

如果datadir的地址格式错误了，比如datadir=datadir=G:\other\Mysql5.7\data

就会出现这样的问题，错误提示不太友好

 

D:\mysql-5.7.28-winx64\bin>mysqld --initialize --console

只需要把目录地址改正确就可以了，datadir=G:\other\Mysql5.7\data

打开管理员权限的命令行进入到对应的bin目录里面执行安装，指定服务名，因为我电脑中还有MySQL8，要配很多个，所以就要命不同的名

 初始化，拿到密码

在本地服务中启动MySQL，选中后启动

 

进入命令行配置密码
