mysql新版本 group by 1055问题，真的很讨厌........终于忍不住了，临时方法缺点是每次启动都要重新设置，于是找方法，但是网上说的都会做了但是启动不了，不生效，亲自看了下mysql.server 配置文件，启动时会读取 /etc/my.cnf 或者安装目录下的my.cnf
1、临时解决方案
SELECT @@sql_mode 查询看到 有这么个讨厌的东西 ONLY_FULL_GROUP_BY ， 于是去掉这个值， set sql_mode = 修改后的值
2、彻底解决
在mysql 的安装目录下 添加 my.cnf
/usr/local/mysql-8.0.23-macos10.15-x86_64
配置文件

It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.

重启mysql ok 彻底解决 (必须是命令行启动，我也搞不懂，在mac的系统便好设置的左下角点mysql启动为什么不生效，命令行配置可以网上搜搜)
