windows 压缩包方式安装

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：
2020-06-20T14:02:59.538460Z 0 [System] [MY-013169] [Server] C:\Application\mysql-8.0.20\bin\mysqld.exe (mysqld 8.0.20) initializing of server in progress as process 808
2020-06-20T14:02:59.634151Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2020-06-20T14:03:10.459155Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2020-06-20T14:03:23.438372Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: <uavdhtD2ul?

非安全模式：空密码警告手动指定root密码即可
2020-06-20T14:15:17.254891Z 0 [System] [MY-013169] [Server] C:\Application\mysql-8.0.20\bin\mysqld.exe (mysqld 8.0.20) initializing of server in progress as process 5564
2020-06-20T14:15:17.275132Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2020-06-20T14:15:30.200787Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2020-06-20T14:15:44.389432Z 6 [Warning] [MY-010453] [Server] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

Root密码设置方式：

非安全方式初始化：mysqladmin -uroot password <新密码>
安全方式初始化：mysqladmin -uroot -p <控制台打印随机生成密码> password <新密码>
通用设置方式：ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY <新密码>

6. Start the MySQL server

启动mysql

控制台直接输入：mysqld（阻塞执行）
安装为windows服务，通过windows服务执行:mysqld --install <服务名> ， net start <服务名>
