MySql 8.0.11-Winxp64(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-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
