[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated

• docker上新装的mysql容器，在本地连接使用后报出错误：
• [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

我们直接上永久解决方案

先查询容器运行状态：docker ps -a

然后进入容器：docker exec -it 容器名 /bin/bash

查看配置文件：cat /etc/mysql/my.cnf

我这里是配置好的
接下来我们进入mysql命令行，查看其sql_mode配置:mysql -u root -p

查看sql_mode：show variables like '%sql_mode';
这是出错情况下的：

我们的目的就是要将sql_mode字段去掉红圈部分
这是修改后的：

• 我们先将上边的配置文件全部复制
• 下边我们就是要在服务器本地新建一个文件，路径还可以是/etc/mysql/my.cnf，将内容复制进去，并在：[mysqld]下的末尾添加sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION，所有内容如下：

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

• 然后我们Esc——>:wq,如果权限不够，会提示加“！”,即:wq!，如果为只读，先set noreadonly，然后再:wq，保存成功并退出。然后我们退出命令行和容器，两个exit解决。
• 接下来停止现在的容器，docker stop 容器名
• 删除容器：docker rm 容器名
  接下来是重点，我们要将本地的配置文件映射为创建容器时使用的配置文件，即以本地配置文件启动容器
  这样以后也好修改，命令：docker run -d -p 3306:3306 -v /etc/mysql/my.cnf:/etc/mysql/my.cnf -e MYSQL_ROOT_PASSWORD=123456 --name mysql01 mysql:latest，我的mysql版本是latest，我也没有映射data文件，想加的可以加。
• 然后docker ps -a查看，没有问题后，我们再次进入新建的容器，接着进入mysql命令行，查看sql_mode，出现了上边的预期成功的sql_mode字段，就算成功。
