docker部署mysql远程连接 解决1251 client does not support ..

作者:互联网

现象:用虚拟机上Docker启动mysql之后无法在本地安装的navicat上远程连接已启动的mysql,错误截图:

原因:mysql 8.0 默认使用 caching_sha2_password 身份验证机制;客户端不支持新的加密方式。

解决方案:

修改用户(root)的加密方式

步骤:
1、进入mysql容器内部
[root@localhost ~]# docker exec -it mysql01 bash

进入之后输入如下命令:

root@8e74f086c2bb:/# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

会提示并进入mysql容器:输入对应命令

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

host为 % 表示不限制ip localhost表示本机使用 plugin非mysql_native_password 则需要修改密码

输入如下命令:

mysql>ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
mysql>flush privileges;

再次查询:

mysql> select host,user,plugin,authentication_string from mysql.user;
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |

                                                                      PHFFzz``OkyuNlZo3K6eObfcdOORjQoG3zvTztdSnkIDOgg5ZkmzRb/ |
