我要评论目录
一.确认windows是否安装mysql
1.按【win+r】打开运行
2.输入【services.msc】打开服务
3.在服务列表中查找mysql，如果有mysql服务则表示windows已经安装mysql，如果没有mysql服务则表示windows没有安装mysql
二.下载mysql安装包
1.进入mysql官网：点击进入，选择windows系统，点击下载
2.选择 no thanks, just start my download.
三.添加配置文件并安装mysql
1.将下载的zip包,解压到想要安装的目录下
2.进入解压后的目录，在bin同等级目录下新建my.ini
3.编辑my.ini,将以下配置粘贴到my.ini
ps:需要注意的是basedir mysql的安装路径,要选择你自己mysql 的安装路径,datadir 选择数据存放的路径,basedir , datadir路径使用正斜杠/ 或双斜杠\\ 否则起不来服务

[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.
# 设置mysql的安装目录
basedir = d:/mysql-8.0.33-winx64/mysql-8.0.33-winx64
# 设置mysql数据库的数据的存放目录
datadir = d:/mysql-8.0.33-winx64/mysql-8.0.33-winx64/data
# 设置3306端口
port = 3306
# 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
# 允许最大连接数
max_connections = 200
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors = 10
# 服务端使用的字符集默认为utf8
character-set-server = utf8mb4
# 创建新表时将使用的默认存储引擎
default-storage-engine = innodb
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin = mysql_native_password
[mysql]
# 设置mysql客户端默认字符集
default-character-set = utf8mb4
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set = utf8mb44.在mysql安装路径下的bin目录中使用cmd打开,输入cmd并回车
5.输入以下命令获取生成的初始密码,最好保存下,后期可能会用
mysqld --initialize --console
6.执行第二条命令,安装mysql服务并启动
mysqld --install mysql
7.查看mysql服务是否已经启动,没有启动的话,手动启动mysql服务
四.登录数据库，修改密码
1.在mysql安装目录下的bin目录下，启动cmd，进入命令提示符后执行以下命令
#连接数据库
mysql -u root -p
#修改mysql数据库密码，这里设置的用户名为root，密码为123456
alter user 'root'@'localhost' identified by '123456';五.配置环境变量
1.进入系统高级设置,进入环境变量设置
2.配置环境变量，这里变量值填写mysql的安装路径
3. 修改path变量,编辑path
六.启动mysql
1.打开cmd,执行mysql -uroot -p输入密码,进入mysql
2.新增数据测试
【总结】
以上就是在windows上安装mysql的全部步骤了。
如果哪里有不明白的可以私信哦~
