压缩包安装官方教程

官方步骤：

1. Extract the main arcHive to the desired install directory

解压安装包到自定义安装目录

2. Optional: also extract the debug-test archive if you plan to execute the Mysql benchmark and test suite

可选项：若想执行mysql基准和测试套件，可解压官网下载的调试测试包

3. Create an option file

创建可选配置文件：定义mysql服务器启动参数 完整配置
配置文件优先级：my.ini > my.cnf
配置文件放置目录：msyql 安装根目录即可

[mysqld]
#  mysql安装目录
# set basedir to your installation path
basedir=E:/mysql

# mysql数组目录
# set datadir to the location of your data directory 
datadir=E:/mydata/data

4. Choose a MySQL Server type

mysqld: mysql正常工作模式
mysqld-debug: mysql 调试工作模式，可调试和自动内存分配检查，排查执行出错

5. Initialize MySQL

初始化mysql数据目录

mysql8.0 账户验证方式变更：mysql_native_password -> caching_sha2_passWord

数据初始化方式：

• 安全，root账户密码随机生成，标识过期，控制台打印：mysqld --initialize --console
• 不安全，root账户不指定密码：mysqld --initialize-insecure --console

安全模式：
