一、MySql安装

https://www.mysql.com/（科学访问）

需要先登录

账号：12****80@qq.com    密码：Jq1****8****

下载完成后拷贝到需要安装的文件夹内解压

把bin目录配置到Path环境变量里面

在mysql的根目录下新建my.ini配置文件

[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.

#安装目录

basedir = D:\develop\mysql-8.0.13-winx64

#data目录

datadir = D:\develop\mysql-8.0.13-winx64\data

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

character-set-server = utf8mb4

performance_schema_max_table_instances = 600

table_definition_cache = 400

table_open_cache = 256

[mysql]

default-character-set = utf8mb4

[client]

default-character-set = utf8mb4

准备就绪后打开命令行，输入mysqld --initialize --console

安装服务，执行命令mysqld --install

安装完成之后，就可以通过命令net start mysql启动MySQL的服务了。

登录mysql，执行命令mysql -uroot -p    然后输入密码

更改加密方式：ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;

更改密码：9527    ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '9527';

刷新：FLUSH PRIVILEGES;

三、navicat连接数据库

四、新建数据库

五、新建表

表建好之后，ctrl+S保存
