新建的mysql，在查询时报异常信息，虽然有正常执行结果。
[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by
在 /etc/my.cnf 文件里加上如下：
sql_mode='NO_ENGINE_SUBSTITUTION'
然后，重启Mysql服务就可以解决了！
