步骤1：解压到安装目录，d:\software\MySQL
步骤2： 添加配置文件 d:\software\MySQL\my.ini
可参考：https://dev.mysql.com/doc/refman/8.0/en/mysqld-option-tables.html
[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:\software\MySQL
datadir = d:\software\MySQL\data
port = 3306
# server_id = .....
default_authentication_plugin=mysql_native_password
# 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
[mysql]
default-character-set = utf8mb4
[client]
default-character-set = utf8mb4
步骤3：初始化数据库
-- 注意：执行日志会生成root账户的初始密码
d:\software\MySQL\bin\mysqld --initialize --console
步骤4：安装服务
d:\software\MySQL\bin\mysqld --install MySQL8
步骤5：启动服务
net start MySQL8
net stop MySQL8
步骤6：修改root密码
mysql -uroot -p $password -- 步骤4生成的临时密码
-- 注意配置选项【my.ini】
-- [mysqld]
-- 设置默认使用mysql_native_password插件认证
-- default_authentication_plugin=mysql_native_password
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
