【解决egg-mysql插件连接不上mysql问题；】解决egg-mysql连接不上MySql服务器报错：Client does not support authentication protocol requested by server; consider upgrading MySQL client

问题原因

通过相关问题查阅，发现是由于navicat版本的问题造成连接失败。mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password
MySql查看版本号-1

LITING:~ liting$ mysql -uroot -p// 进入mysql Enter password://输入mysql密码，如下提示表示登录成功 Welcome to the MySQL monitor.Commands end with ; or \g.

MySql查看版本号-2（可以进入mysql后通过mysql命令查看）

mysql> select version(); +-----------+ | version() | +-----------+ | 8.0.14| +-----------+ 1 row in set (0.00 sec)

解决问题

1.进入mysql

LITING:~ liting$ mysql -uroot -p Enter password:// mysql密码 Welcome to the MySQL monitor.Commands end with ; or \g. Your MySQL connection id is 26 Server version: 8.0.14 MySQL Community Server - GPLCopyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners.Type 'help; ' or '\h' for help. Type '\c' to clear the current input statement.

2.输入命令修改加密规则
1.ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER;
password替换为mysql连接密码

ALTER USER 'root'@'localhost' IDENTIFIED BY '12345678' PASSWORD EXPIRE NEVER;

2.ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;
password为修改的新密码。

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

3.刷新权限，使修改生效。

FLUSH PRIVILEGES;

4.查看表中相关信息，确认修改是否真正生效

mysql> use mysql; //先使用命令 use mysql Database changed mysql> select user,host,plugin from user where user='root'; // 在输入该命令 +------+-----------+-----------------------+ | user | host| plugin| +------+-----------+-----------------------+ | root | localhost | mysql_native_password | +------+-----------+-----------------------+ 1 row in set (0.00 sec)

5.通过navicat连接测试
