[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

今天在链接远程数据库（我的远程数据库是mysql5.7的）时报了一个“[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”这样的错误，以前从来没有遇见过，现在记录一下，免得以后遇到。

我的mysql是在CentOS7.1下面的5.7.17

在 /etc/my.cnf 文件里加上如下：

sql_mode='NO_ENGINE_SUBSTITUTION'

然后，重启Mysql服务

systemctl restart mysqld
