Docker部署mysql远程连接 解决2059

安装MySQL

docker run -di --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 --restart=always mysql

navicat连接报错：

原因：

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，navicat驱动目前不支持新加密规则

解决：

# 远程连接请将'localhost'换成'%'
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #更改加密方式
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'; #更新用户密码

FLUSH PRIVILEGES; #刷新权限

[root@localhost ~]# docker exec -it mysql /bin/bash
root@f71fb11d4312:/# mysql -u root -p
Enter password:
