1.解压

mysql-8.0.19-winx64.zip

演示文件目录

C:\Program Files\mysql-8.0.19-winx64

2.创建两个文件夹

C:\Program Files\mysql-8.0.19-winx64\data
C:\Program Files\mysql-8.0.19-winx64\logs

3.设置环境变量

4.新建my.ini配置

[mysqld]
#安装目录
basedir = C:\Program Files\mysql-8.0.19-winx64
#数据文件目录
datadir = C:\Program Files\mysql-8.0.19-winx64\data
port = 3306
server_id = 1
general_log = ON
general_log_file = C:\Program Files\mysql-8.0.19-winx64\logs\mysql.log
log_error = C:\Program Files\mysql-8.0.19-winx64\logs\error.log
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
#sql_mode=ONLY_FULL_GROUP_BY,NO_AUTO_VALUE_ON_ZERO,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,PIPES_AS_CONCAT,ANSI_QUOTES
[mysql]
default-character-set = utf8mb4

[client]
default-character-set = utf8mb4

5.管理员权限开启CMD窗口

5.1 初始化

mysqld --initialize --console #不用特别指定default file默认会使用my.ini

控制台输入如下表示成功

C:\Program Files\mysql-8.0.19-winx64>mysqld --initialize --console
2020-04-21T10:11:25.148253Z 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.

Warning暂时没做理会，没发现使用异常
记下上面日志最后面的root的初始化密码Fv?_a7%jn_R(，下面要用到

5.2 安装服务

mysqld --install [服务名] #不写服务名默认为mysql

5.3 启动数据库

C:\Program Files\mysql-8.0.19-winx64>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。

5.4 使用临时密码登陆数据库

C:\Program Files\mysql-8.0.19-winx64>mysql -u root -p
Enter password: ************

5.5 修改root初始化密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '要改的新密码';

执行命令查看输出log

mysqld --console

D:\Program Files\mysql-8.0.19-winx64>mysqld --console

关键错误

TCP/IP, --shared-memory, or --named-pipe should be configured on NT OS

解决方案

修改my.ini,添加shared-memory

这个问题是由于我的MySQL的的的更新至8版本以上了，在安装的时候我并没有指定用户登入密码加密方式，所以默认被设置为caching_sha2_password
解决方法：

mysql> show variables like 'default_authentication_plugin';

查看本地mysql用户的信息

mysql> select host,user,plugin from mysql.user;

注意 caching_sha2_password， 只修改root的密码加密方式就可以了

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

mysql> select host,user,plugin from mysql.user;

使用tdm-gcc
https://jmeubank.github.io/tdm-gcc/download/
然后再系统环境变量path里把tdragon的位置上移到cygwin上面，
让系统调用gcc时先识别tdragon的gcc，或者直接把cygwin的环境路径直接删除了，
或者直接从goland里的settings->Go->GoPath里添加tdragon的路径，如下图
