Ignoring query to other database 解决方法

今天登陆服务器，查看数据同步情况，出现逗比的问题一个。

Welcome to the MySQL monitor.  Commands end with ; or \g.

Server version: 5.5.44-0ubuntu0.14.04.1-log (Ubuntu)

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

mysql> show slave status\G;
Ignoring query to other database
Ignoring query to other database
mysql> show database;
Ignoring query to other database
mysql>

show databases出现Ignoring query to other database错误，又试了几个命令和sql全部提示Ignoring query to other database错误。

折腾了半天才发现原来是在连接mysql时没有"-u"参数导致的。我一时手滑，写成：

mysql -root -p

少了个“u”，正确写法如下：
mysql -u root -p

重新连接mysql　加上-u参数　一切正常。

凡事都不能马虎啊。。。
