1. 解压zip包到安装目录
首先，将mysql/49300.html">mysql-8.0.11-winx64.zip 解压缩到 安装D:/mysql-8.0.11-winx64 目录下，
2.配置文件
在安装根目录下添加 my.ini
基本配置文件（my）
[mysqld]basedir = D:/mysql-8.0.11-winx64datadir = D:/mysql-8.0.11-winx64/dataport = 3306lower_case_table_names = 2default_authentication_plugin=mysql_native_password
参考 基本配置：
[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:/Program/MySQLdatadir = D:/DBs/MySQLport = 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 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES character-set-server = utf8mb4performance_schema_max_table_instances = 600table_definition_cache = 400table_open_cache = 256[mysql]default-character-set = utf8mb4[client]default-character-set = utf8mb4
3.初始化数据库
在MySQL安装目录的 bin 目录下执行命令：
mysqld --initialize --console
执行完成后，会打印 root 用户的初始默认密码，比如：
2018-04-20T02:35:01.507037Z 0 [Warning] [MY-010915] [Server] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.2018-04-20T02:35:01.507640Z 0 [System] [MY-013169] [Server] D:/Program/MySQL8/bin/mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 110642018-04-20T02:35:01.508173Z 0 [ERROR] [MY-010340] [Server] Error message file 'D:/Program/MySQL/share/english/errmsg.sys' had only 1090 error messages, but it should contain at least 4512 error messages. Check that the above file is the right version for this program!2018-04-20T02:35:05.464644Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: APWCY5ws&hjQ2018-04-20T02:35:07.017280Z 0 [System] [MY-013170] [Server] D:/Program/MySQL8/bin/mysqld.exe (mysqld 8.0.11) initializing of server has completed
其中，第4行的“APWCY5ws&hjQ”就是初始密码，在没有更改密码前，需要记住这个密码，后续登录需要用到。
如果没记住，那也没事，删掉初始化的 datadir 目录，再执行一遍初始化命令，又会重新生成的。当然，也可以使用安全工具，强制改密码，用什么方法，自己随意。
4.安装服务
在MySQL安装目录的 bin 目录下执行命令：
mysqld --install [服务名]
4.启动服务
net start MySQL
更改密码和密码认证插件
在MySQL安装目录的 bin 目录下执行命令：
mysql -uroot -p
这时候会提示输入密码，记住了第3步的密码，填入即可登录成功，进入MySQL命令模式。
之前，MySQL的密码认证插件是“mysql_native_password”，而现在使用的是“caching_sha2_password”。
因为当前有很多数据库工具和链接包都不支持“caching_sha2_password”，为了方便，我暂时还是改回了“mysql_native_password”认证插件。
在MySQL中执行命令：
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
修改密码验证插件，同时修改密码。
如果想默认使用“mysql_native_password”插件认证，可以在配置文件中配置default_authentication_plugin项。
[mysqld]default_authentication_plugin=mysql_native_password
