MySql 8.0.11-Winxp64(免安装版)配置教程
人气:01. 解压zip包到安装目录
首先，将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-winx64 datadir = D:\mysql-8.0.11-winx64\data port = 3306 lower_case_table_names = 2 default_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\MySQL datadir = D:\DBs\MySQL port = 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 = 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
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 11064 2018-04-20T02:35:01.508173Z 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&hjQ 2018-04-20T02:35:07.017280Z 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
