MySQL8.0.24免安装版配置教程

官网下载地址：https://dev.mysql.com/downloads/mysql/

1. 点击官网下载地址进入下载页面，点击页面中的Archives进入版本选择页面，选择8.0.24压缩版进行下载
   
   
2. 将下载后的压缩包解压到要安装的目录
   以下图中D:\mysql-8.0.24-winx64安装路径为例
   解压后是不存在my.ini文件的，需要手动添加。新增my.ini文件后在文件中加入以下配置。

[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 = D:\\mysql-8.0.24-winx64
datadir = D:\\mysql-8.0.24-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 
character-set-server = utf8mb4
performance_schema_max_table_instances = 600
table_definition_cache = 400
table_open_cache = 256
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
lower_case_table_names = 1
skip-log-bin
 
[mysql]
default-character-set = utf8mb4

注：若安装路径不在本示例路径下，需要改basedir、datadir两个参数

3. 配置环境变量
   我的电脑–>右键属性–>高级系统设置–>环境变量
   
   
4. 安装mysql服务
   启动管理员模式下的cmd，并将路径切换至mysql安装目录下的bin目录，输入以下命令:

cd D:\mysql-8.0.24-winx64\bin mysqld –install
1

5. 初始化数据库
   输入以下命令

cd D:\mysql-8.0.24-winx64\bin mysqld --initialize --console
1

注：执行完该命令后会出现数据库root用户的初始密码，一定要复制保存，后面登录需要用到

6. 启动MySQL服务

cd D:\mysql-8.0.24-winx64\bin net start mysql
1

7. 进入数据库的配置
   输入mysql -u root -p后会让输入密码，密码为前面初始化数据时生成的密码，输入正确后就会出现如下界面，表示进入了MySQL命令模式
   
8. 修改初始密码
   输入以下命令

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root' PASSWORD EXPIRE NEVER;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
