[err] 1055

本人mysql安装在ubuntu16.04上，mysql版本是5.7.19；在创建表和插入数据时报了

[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

在网上查到的解决方案是修改/etc/mysql/my.cnf文件，在其中添加如下内容，然后重启mysql（重启命令：service mysql restart）

[mysqld]
sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘

我尝试了之后，发现重启出现问题。

后来，我发现该版本的mysql配置引用了/etc/mysql/conf.d文件夹以及/etc/mysql/mysql.conf.d文件夹，且配置都放在了mysql.conf.d文件夹下的mysqld.cnf文件中，故将上述内容修改在该文件中，该文件中有[mysqld]

故只需要在该标签的后续内容添加

sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘

，并重启mysql。

完美解决。。。。
