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

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   ## mysql01是容器的别名,这里也可以用容器的id代替

2、登录mysql

root@e285125c99d6:/# mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.

3、设置用户配置项

1)、查看用户信息


mysql> select host,user,plugin,authentication_string from mysql.user; 
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | caching_sha2_password | $A$005$HF7;krfwhkKHp5fPenQm4J2dm/RJtbbyjtCUVdDCcboXQw3ALxsif/sS1 |
| localhost | mysql.infoschema | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.session    | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.sys        | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
+-----------+------------------+-----------------------+-----------------------------------------

备注: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

2)、修改加密方式

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';  ### 123456 mysql的登录密码
flush privileges;

然后再查看用户信息

mysql> select host,user,plugin,authentication_string from mysql.user;
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
| localhost | mysql.infoschema | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.session    | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | mysql.sys        | caching_sha2_password | $A$005$THISISACOMBINATIONOFINVALIDSALTANDPASSWORDTHATMUSTNEVERBRBEUSED |
| localhost | root             | mysql_native_password | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
