MySql 8.0.11Winxp64(免安装版)配置教程

  1. 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-winx64d

1. 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]

  1. Remove leading # and set to the amount of RAM for the most important data
  2. cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
  3. innodb_buffer_pool_size = 128M
  4. Remove leading # to turn on a very important data integrity option: logging
  5. changes to the binary log between backups.
  6. log_bin
  7. These are commonly set, remove the # and set as required. basedir = D:\Program\MySQL datadir = D:\DBs\MySQL port = 3306
  8. server_id = .....
  9. Remove leading # to set options mainly useful for reporting servers.
  10. The server defaults are faster for transactions and fast SELECTs.
  11. Adjust sizes as needed, experiment to find the optimal values.
  12. join_buffer_size = 128M
  13. sort_buffer_size = 2M
  14. 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
