null, message from server: "Host 'MS-IWURIWYEOZMP' is not allowed to connect to this MySQL server

引用:java.sql.SQLException: null, message from server: “Host ‘223.72.41.7’ is not allowed to connect to this MySQL server” 客户端访问时报错。引用:如果host的值是localhost，说明只支持本地连接，不能远程登录。 引用:ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'不予理会。
根据给出的错误信息，"Host 'MS-IWURIWYEOZMP' is not allowed to connect to this MySQL server"，可以推断出用户在连接MySQL服务器时遇到了问题。错误信息中提到了服务器不允许来自主机"MS-IWURIWYEOZMP"的连接。这可能是由于服务器配置的限制导致的。
解决这个问题的方法有两种。一种是通过更改MySQL服务器的访问权限来允许来自主机"MS-IWURIWYEOZMP"的连接。这可以通过在MySQL服务器上修改相应的配置文件或者通过命令行操作来实现。另一种方法是使用允许连接的主机名或IP地址来访问MySQL服务器。这需要在连接数据库时指定正确的主机名或IP地址。
另外，还需要注意的是，如果出现了其他的错误信息，比如"Duplicate entry '%-root' for key 'PRIMARY'"，这可能是由于数据库中出现了重复的主键值所致。解决这个问题可以通过删除或修改重复的主键值来解决。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
