原因
执行如下命令：
SELECT @@GLOBAL.sql_mode;
MySQL5.7版本默认设置了 mysql sql_mode = only_full_group_by 属性.这个属性对语法要求的更严了一些，具体可查看如下
官网描述：
Reject queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on (uniquely determined by) GROUP BY columns.
As of MySQL 5.7.5, the default SQL mode includes ONLY_FULL_GROUP_BY. (Before 5.7.5, MySQL does not detect functional dependency and ONLY_FULL_GROUP_BY is not enabled by default. For a description of pre-5.7.5 behavior, see the MySQL 5.6 Reference Manual.)
A MySQL extension to standard SQL permits references in the HAVING clause to aliased expressions in the select list. Before MySQL 5.7.5, enabling ONLY_FULL_GROUP_BY disables this extension, thus requiring the HAVING clause to be written using unaliased expressions. As of MySQL 5.7.5, this restriction is lifted so that the HAVING clause can refer to aliases regardless of whether ONLY_FULL_GROUP_BY is enabled.
对于上面的sql语句，order by里面的t.createTime必须也要在group by里面。
解决方法
- 关闭only_full_group_by属性
1.1. 临时关闭
未尝试，可行性未知。
全局
SET GLOBAL sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
某个库
sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
这里是暂时的修改，重启mysql以后，这里的改动可能会失效。需要修改mysql的配置
1.2. 永久关闭
Linux下my.cnf或Windows下my.ini
在[mysqld]下追加：
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
重启mysql
- 修改sql
将上面的sql修改为：
select t.createTime,t.`status`,count(t.`status`) as count from http_sequence_log t where t.pguid = 'ec8fce9c11504a62969d6b827a0770f7' group by t.`status`,t.createTime order by t.createTime desc limit 10
将order by里面的 t.createTime也放在group by里面
