Docker 安装mysql并解决ERROR 1045 (28000):问题

安装步骤

我习惯用dockerfile做一些自定义的配置。

FROM mysql:8.0.23

ENV MYSQL_ROOT_PASSWORD   my_root_password
ENV MYSQL_DATABASE        test
ENV MYSQL_USER            app
ENV MYSQL_PASSWORD        mypassword
ENV ALLOW_EMPTY_PASSWORD  yes
EXPOSE 13306:3306

# 该参数命令是用来更改所有表的默认编码和排序规则以使用UTF-8（utf8mb4）命令如下--character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
#docker run -itd  -p 13306:3306 --name=mysql8 mymysql:1.0.0 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
ENTRYPOINT ["docker-entrypoint.sh"]
CMD ["mysqld"]

启动容器

如果要对数据库表结构做utf8mb4编码更改，请在执行docker run命令时，在尾部追加--character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci。

# 示例为更改了表的默认编码为 utf8mb4编码
$ docker run -itd  -p 13306:3306 --name=mysql8 mymysql:1.0.0 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

[root@stresstest-test-wx-004 docker]# 查看 容器启动情况

注意事项

注意 进入容器后，连接mysql数据库一定要加 -h 参数 不然连接数据库会报错ERROR 1045 (28000): Access denied for user下面记录完整的访问流程。

[root@stresstest-test-wx-004 docker]# docker exec -it  mysql8 bash
root@ce2ee419dc24:/# 注意 一定要加 -h 参数 不然会报错 ERROR 1045 (28000): Access denied for user
root@ce2ee419dc24:/# mysql -h localhost -u root -p
