mysql 客户端启动报错

麻烦提供下配置的my.cnf文件
看你输出的版本号是mysql  Ver 8.0.25 你装的是GreatSQL 8.0.32-25
是否存在两个数据库？如果是的话你的数据目录、my.cnf文件、端口号等要隔离开，否则会出现共用同一个。
如果只要测试体验GreatSQL 可以用Docker 直接拉取即可

[client]

user = root

你把socket= /home/data_redo/yxz/data/GreatSQL/mysql.sock 放在这里了
你自己指定下 -S 使用socket 链接

发一下 你的登录命令

直接用SOCKET登录看一下
