[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

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';
