Mysql错误:Ignoring query to other database解决方法

jiawang

今天登陆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
错误如下：

[root@strong bin]# ./mysql -root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 72

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

mysql>
mysql> show databases;
Ignoring query to other database



折腾了半天才发现原来是在连接mysql时没有"-u"参数导致的
重新连接mysql　加上-u参数　一切正常
[root@strong bin]# ./mysql -uroot -p
