很多人在SO上遇到过这个问题,但几乎所有答案都没用。

对于管理服务器连接,连接选项卡,高级子选项卡中的MySQL Workbench 6.08,您必须选中使用旧身份验证协议框。'

尝试与mysql
命令行客户端连接时遇到同样的问题,我可以使用--skip-secure-auth
选项来避免错误。
例如:
mysql DBNAME -h HOST_NAME_OR_IP -u DB_USER --password="PASSWORD" --skip-secure-auth
其他 mysqlX 命令的相同参数,例如mysqldump
。

经过多次试验/错误后,问题被缩小为使用旧加密方式的密码。
mysql> select User, Password from mysql.user;
| user1 | *113D91F3A36D29C287C457A20D602FA384B8569F |
| user2 | 5d78f2535e56dfe0 |
Navicat等工具不会自动使用较新的样式密码,你必须明确告诉它不要使用旧样式(在Navicat中,它叫做Advanced / Use OLD_PASSWORD tncryption) - 这就是我们被绊倒的地方。
如果你正在使用mysql shell,你可以使用;
mysql> update mysql.user set password=PASSWORD("NEWPASSWORD") where User='testuser';
Query OK, 1 row affected
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select User, Password from mysql.user WHERE user = 'testuser';
| testuser | *B845F78DCA29B8AE945AB9CFFAC24A9D17EB5063 |
如果您想查找受此问题影响的所有用户;
mysql> SELECT Host, User, Password FROM mysql.user WHERE LENGTH(Password) = 16;
某些版本的Django不允许您在选项中使用secure-auth
,但对于您可以使用的那些;
'OPTIONS': {
'secure-auth': False
}
如果不支持,则会产生;
TypeError: 'secure-auth' is an invalid keyword argument for this function
对于那些将来遇到麻烦的人来说,这应该是一个快速的答案。
