修改宿主机上的my.cnf，把这个参数加进去，然后重新创建容器，应该就可以了

这个是本地的，我做了连接运行不起
容器我都删除，重新运行了几次，都运行不起

不好意思，GreatSQL Docker提供了相关变量，启动时加上 -e LOWER_CASE_TABLE_NAMES=1 参数就行

详情参考 https://gitee.com/GreatSQL/GreatSQL-Docker/tree/master/GreatSQL

在my.cnf 里面写明lower_case_table_names 再映射进去，拉起来

那是因为你原来已经初始化了一个实例，你删除容器，但是你宿主机的物理文件还在，你把目录清空，删除容器，把配置加进去再重新拉容器。

我这样启动的，select t.* from test T left join tname b on t.id = b.id。这样会报错找到不到“T”，
如果表test 大写，sql小写也找不到表。看起来就是-e参数没有生效

已解决，-e LOWER_CASE_TABLE_NAMES = 1 必须这样写，不能改小写。启动加入可以看到也初始化。小写就直接看到docker启动成功id号。
