[已解决] mysql 客户端启动报错

2051 5 2024-2-25 14:38
参考 https://greatsql.cn/docs/8032-25 ... centos-install.html 安装完成,确认server 进程已经启动,随后,尝试进入客户端;

mysql 版本信息:mysql  Ver 8.0.25 for Linux on x86_64 (Source distribution)


报错:ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

/tmp 目录下只有 mysqlx.sock;

尝试:建立软连接ln -s mysqlx.sock mysql.sock

报错:ERROR 2007 (HY000): Protocol mismatch; server version = 11, client version = 10


其他信息:
datadir目录下存在mysql.sock mysql.sock.lock文件,不知有什么用

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

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
王权富贵 2024-2-26 10:18:23
发一下 你的登录命令

直接用SOCKET登录看一下
