这是刚安装的最新版的mysql教程，希望大家喜欢：

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
